64 <sect1 id="introduction"><title>Introduction</title>
66 <application>Internet Junkbuster</application> is a web proxy with advanced
67 filtering capabilities for protecting privacy, filtering web page content,
68 managing cookies, controlling access, and removing ads, banners, pop-ups and
69 other obnoxious Internet Junk. <application>Junkbuster</application> has a
70 very flexible configuration and can be customized to suit individual needs
71 and tastes. <application>Internet Junkbuster</application> has application
72 for both stand-alone systems and multi-user networks.
76 This documentation is included with the current development version of
77 <application>Internet Junkbuster</application> and is incomplete at this
78 point. The most up to date reference for the time being is still the comments
79 in the source files and in the individual configuration files. Development
80 of version 3.0 is currently underway, and includes many significant changes and
81 enhancements over earlier verions. The target release date for stable v3.0 is
86 Since this is a development version, some features are in the process of
87 being implemented. This documentation may be slightly out of sync as a
88 result. And there <emphasis>are</emphasis> bugs, though hopefully not many!
92 <!-- ~~~~~ New section ~~~~~ -->
94 <title>New Features</title>
96 In addition to <application>Junkbuster's</application> traditional features
97 of ad and banner blocking and cookie management, this is a list of new
98 features currently under development:
106 A browser based configuration utility (WIP at
107 <ulink url="http://i.j.b">http://i.j.b</ulink>).
113 Modularized configuration that will allow for system wide settings, and
114 individual user settings. (not implemented yet)
120 Blocking of annoying pop-up browser windows (previously available as a
127 Support for HTTP/1.1 (partially implemented at this point).
133 Support for Perl Compatible Regular Expressions in the configuration files, and
134 generally a more sophisticated configuration syntax over previous versions.
140 Web page content filtering.
154 In addition, the configuration is more versatile overall.

164 <!-- ~~~~~ New section ~~~~~ -->
165 <sect1 id="installation"><title>Installation</title>
167 <application>Junkbuster</application> is available as raw source code, or
168 pre-compiled binaries. See the <ulink
169 url="http://sourceforge.net/projects/ijbswa/">Junkbuster Home Page</ulink>
170 for current release info. <application>Junkbuster</application> is also available
172 url="http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/ijbswa/current/">CVS</ulink>.
173 This is the recommended approach at this time. But please be aware that CVS
174 is constantly changing, and it may break in mysterious ways.
177 <!-- ~~~~~ New section ~~~~~ -->
178 <sect2 id="installation-source"><title>Source</title>
180 For gzipped tar archives, unpack the source:
185 tar xzvf ijb_source_* [.tgz or .tar.gz]
186 cd ijb_source_2.9.10_beta
191 For retrieving the current CVS sources, you'll need the CVS
192 package installed first. To download CVS source:
197 cvs -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa login
198 cvs -z3 -d:pserver:anonymous@cvs.ijbswa.sourceforge.net:/cvsroot/ijbswa co current
204 This will create a directory named <filename>current/</filename>, which will
205 contain the source tree.
209 Then, in either case, to build from tarball/CVS source:
214 ./configure (--help to see options)
215 make (the make from gnu, gmake for *BSD)
217 make -n install (to see where all the files will go)
218 make install (to really install)
223 For Redhat and SuSE Linux RPM packages, see below.
229 <!-- ~~~~~ New section ~~~~~ -->
230 <sect2 id="installation-rh"><title>Red Hat</title>
232 To build Redhat RPM packages, install source as above. Then:
237 autoheader [suggested for CVS source]
238 autoconf [suggested for CVS source]
245 This will create both binary and src RPMs in the usual places. Example:
249 /usr/src/redhat/RPMS/i686/junkbuster-2.9.10-1.i686.rpm
252 /usr/src/redhat/SRPMS/junkbuster-2.9.10-1.src.rpm
256 To install, of course:
261 rpm -Uvv /usr/src/redhat/RPMS/i686/junkbuster-2.9.10-1.i686.rpm
266 This will place the <application>Junkbuster</application> configuration
267 files in <filename>/etc/junkbuster/</filename>, and log files in
268 <filename>/var/log/junkbuster/</filename>.
273 <!-- ~~~~~ New section ~~~~~ -->
274 <sect2 id="installation-suse"><title>SuSE</title>
276 To build SuSE RPM packages, install source as above. Then:
281 autoheader [suggested for CVS source]
282 autoconf [suggested for CVS source]
289 This will create both binary and src RPMs in the usual places. Example:
293 /usr/src/packages/RPMS/i686/junkbuster-2.9.10-1.i686.rpm
296 /usr/src/packages/SRPMS/junkbuster-2.9.10-1.src.rpm
300 To install, of course:
305 rpm -Uvv /usr/src/packages/RPMS/i686/junkbuster-2.9.10-1.i686.rpm
310 This will place the <application>Junkbuster</application> configuration
311 files in <filename>/etc/junkbuster/</filename>, and log files in
312 <filename>/var/log/junkbuster/</filename>.
318 <!-- ~~~~~ New section ~~~~~ -->
319 <sect2 id="installation-os2"><title>OS/2</title>
326 The OS/2 version of <application>Junkbuster</application> requires the EMX
327 runtime library to be installed. The EMX runtime library is available on
328 the hobbes OS/2 archive, among many other locations:
329 <ulink url="http://hobbes.nmsu.edu/cgi-bin/h-search?sh=1&button=Search&key=emxrt.zip&stype=all&sort=type&dir=%2Fpub%2Fos2%2Fdev%2Femx%2Fv0.9d">http://hobbes.nmsu.edu/cgi-bin/h-search?sh=1&button=Search&key=emxrt.zip&stype=all&sort=type&dir=%2Fpub%2Fos2%2Fdev%2Femx%2Fv0.9d</ulink>
333 <application>Junkbuster</application> is packaged in a WarpIN self-
334 installing archive. The self-installing program will be named depending
335 on the release version, something like:
336 <filename>ijbos123.exe</filename>. In order to install it, simply run
337 this executable or double-click on its icon and follow the WarpIN
338 installation panels. A shadow of the <application>Junkbuster</application>
339 executable will be placed in your startup folder so it will start
340 automatically whenever OS/2 starts.
344 The directory you choose to install <application>Junkbuster</application>
345 into will contain all of the configuration files.
349 If you would like to build binary images on OS/2 yourself, you will need
350 a working EMX/GCC environment, plus several Unix-like tools. The Hobbes
351 OS/2 archive is a good place to start when building such an environment.
352 A set of Unix-like tools named gnupack is located here:
353 <ulink url="http://hobbes.nmsu.edu/cgi-bin/h-search?sh=1&key=gnupack&stype=all&sort=type&dir=%2Fpub%2Fos2%2Fapps">http://hobbes.nmsu.edu/cgi-bin/h-search?sh=1&key=gnupack&stype=all&sort=type&dir=%2Fpub%2Fos2%2Fapps</ulink>
356 Once you have the source code unpacked as above, you can build the binaries
357 from the <filename>current/</filename> directory:
371 <!-- ~~~~~ New section ~~~~~ -->
372 <sect2 id="installation-win"><title>Windows</title>
373 <para>Click-click. (I need help on this. Not a clue here. Also for
374 configuration section below. HB.)
378 <!-- ~~~~~ New section ~~~~~ -->
379 <sect2 id="installation-other"><title>Other</title>
381 Some quick notes on other Operating Systems.
385 For FreeBSD (and other *BSDs?), the build will require <command>gmake</command>
386 instead of the included <command>make</command>. <command>gmake</command> is
387 available from <ulink url="http://www.gnu.org">http://www.gnu.org</ulink>.
388 The rest should be the same as above for Linux/Unix.
395 <!-- ~ End section ~ -->
398 <!-- ~~~~~ New section ~~~~~ -->
399 <sect1 id="configuration"><title>Junkbuster Configuration</title>
401 For Unix, *BSD and Linux, all configuraton files are located in
402 <filename>/etc/junkbuster/</filename> by default. For MS Windows and OS/2,
403 these are all in the same directory as the
404 <application>Junkbuster</application> executable. The name and number of
405 configuration files has changed from previous versions, and is subject to
406 change as development progresses.
410 The installed defaults provide a reasonable starting point, though possibly
411 aggressive by some standards. For the time being, there are only three
412 default configuration files (this will change in time):
420 The main configuration file is named <filename>config</filename>
421 on Linux, Unix, BSD, and OS/2, and <filename>config.txt</filename> on
422 Windows. On Amiga, it is
423 <filename>AmiTCP:db/junkbuster/config</filename>.
429 The <filename>ijb.action</filename> file is used to define various
430 <quote>actions</quote> relating to images, banners, pop-ups, access
431 restrictions, banners and cookies. There is a CGI based editor for this
432 file that can be accessed via <ulink
433 url="http://i.j.b">http://i.j.b</ulink>. This is the easiest method of
434 configuring actions. (Still under active development. Other actions
435 files are included as well with differing levels of filtering
436 and blocking, e.g. <filename>ijb-basic.action</filename>.)
442 The <filename>re_filterfile</filename> file can be used to rewrite the raw
443 page content, including text as well as embedded HTML and JavaScript.
451 <filename>ijb.action</filename> and <filename>re_filterfile</filename>
452 can use Perl style regular expressions for maximum flexibility. All files use
453 the <quote><literal>#</literal></quote> character to denote a comment. Such
454 lines are not processed by <application>Junkbuster</application>. After
455 making any changes, restart <application>Junkbuster</application> in order
456 for the changes to take effect.
460 While under development, the configuration content is subject to change.
461 The below documentation may not be accurate by the time you read this.
462 Also, what constitutes a <quote>default</quote> setting, may change, so
463 please check all your configuration files on important issues.
466 <!-- ~~~~~ New section ~~~~~ -->
469 <title>The Main Configuration File</title>
471 Again, the main configuration file is named <filename>config</filename> on
472 Linux/Unix/BSD and OS/2, and <filename>config.txt</filename> on Windows.
473 Configuration lines consist of an initial keyword followed by a list of
474 values, all separated by whitespace (any number of spaces or tabs). For
482 <emphasis>blockfile blocklist.ini</emphasis>
489 Indicates that the blockfile is named <quote>blocklist.ini</quote>.
493 A <quote><literal>#</literal></quote> indicates a comment. Any part of a
494 line following a <quote><literal>#</literal></quote> is ignored, except if
495 the <quote><literal>#</literal></quote> is preceded by a
496 <quote><literal>\</literal></quote>.
500 Thus, by placing a <quote><literal>#</literal></quote> at the start of an
501 existing configuration line, you can make it a comment and it will be treated
502 as if it weren't there. This is called <quote>commenting out</quote> an
503 option and can be useful to turn off features: If you comment out the
504 <quote>logfile</quote> line, <application>junkbuster</application> will not
505 log to a file at all. Watch for the <quote>default:</quote> section in each
506 explanation to see what happens if the option is left unset (or commented
511 Long lines can be continued on the next line by using a
512 <quote><literal>\</literal></quote> as the very last character.
516 There are various aspects of <application>Junkbuster</application> behavior
521 <!-- ~~~~~ New section ~~~~~ -->
524 <title>Defining Other Configuration Files</title>
527 <application>Junkbuster</application> can use a number of other files to tell it
528 what ads to block, what cookies to accept, etc. This section of the
529 configuration file tells <application>Junkbuster</application> where to find
530 all those other files.
534 On <application>Windows</application>, <application>Junkbuster</application>
535 looks for these files in the same directory as the executable. On Unix and
536 OS/2, <application>Junkbuster</application> looks for these files in the current
537 working directory. In either case, an absolute path name can be used to
542 When development goes modular and multiuser, the blocker, filter, and
543 per-user config will be stored in subdirectories of <quote>confdir</quote>.
544 For now, only <filename>confdir/templates</filename> is used for storing HTML
545 templates for CGI results.
549 The location of the configuration files:
556 <emphasis>confdir /etc/junkbuster</emphasis> # No trailing /, please.
563 The directory where all logging (i.e. <filename>logfile</filename> and
564 <filename>jarfile</filename>) takes place. No trailing
565 <quote><literal>/</literal></quote>, please:
572 <emphasis>logdir /var/log/junkbuster</emphasis>
579 Note that all file specifications below are relative to
580 the above two directories!
584 The <quote>ijb.action</quote> file contains patterns to specify the actions to
585 apply to requests for each site. Default: Cookies to and from all
586 destinations are kept only during the current browser session (i.e. they
587 are not saved to disk). Popups are disabled for all sites. All sites are
588 filtered if <quote>re_filterfile</quote> specified. No sites are blocked. An
589 empty image is displayed for filtered ads and other images (formerly
590 <quote>tinygif</quote>). The syntax of this file is explained in detail <link
591 linkend="actionsfile">below</link>.
598 <emphasis>actionsfile ijb.action</emphasis>
605 The <quote>re_filterfile</quote> file contains content modification rules.
606 These rules permit powerful changes on the content of Web pages, e.g., you
607 could disable your favourite JavaScript annoyances, rewrite the actual
608 content, or just have some fun replacing <quote>Microsoft</quote> with
609 <quote>MicroSuck</quote> wherever it appears on a Web page. Default: No
610 content modification, or whatever the developers are playing with :-/
617 <emphasis>re_filterfile re_filterfile</emphasis>
624 The logfile is where all logging and error messages are written. The logfile
625 can be useful for tracking down a problem with
626 <application>Junkbuster</application> (e.g., it's not blocking an ad you
627 think it should block) but in most cases you probably will never look at it.
631 Your logfile will grow indefinitely, and you will probably want to
632 periodically remove it. On Unix systems, you can do this with a cron job
633 (see <quote>man cron</quote>). For Redhat, a <command>logrotate</command>
634 script has been included.
638 On SuSE Linux systems, you can place a line like <quote>/var/log/junkbuster.*
639 +1024k 644 nobody.nogroup</quote> in <filename>/etc/logfiles</filename>, with
640 the effect that cron.daily will automatically archive, gzip, and empty the
641 log, when it exceeds 1M size.
645 Default: Log to the a file named <filename>logfile</filename>.
646 Comment out to disable logging.
653 <emphasis>logfile logfile</emphasis>
660 The <quote>jarfile</quote> defines where
661 <application>Junkbuster</application> stores the cookies it intercepts. Note
662 that if you use a <quote>jarfile</quote>, it may grow quite large. Default:
663 Don't store intercepted cookies.
670 <emphasis>#jarfile jarfile</emphasis>
677 If you specify a <quote>trustfile</quote>,
678 <application>Junkbuster</application> will only allow access to sites that
679 are named in the trustfile. You can also mark sites as trusted referrers,
680 with the effect that access to untrusted sites will be granted, if a link
681 from a trusted referrer was used. The link target will then be added to the
682 <quote>trustfile</quote>. This is a very restrictive feature that typical
683 users most propably want to leave disabled. Default: Disabled, don't use the
691 <emphasis>#trustfile trust</emphasis>
698 If you use the trust mechanism, it is a good idea to write up some online
699 documentation about your blocking policy and to specify the URL(s) here. They
700 will appear on the page that your users receive when they try to access
701 untrusted content. Use multiple times for multiple URLs. Default: Don't
702 display links on the <quote>untrusted</quote> info page.
709 <emphasis>trust-info-url http://www.your-site.com/why_we_block.html</emphasis>
710 <emphasis>trust-info-url http://www.your-site.com/what_we_allow.html</emphasis>
718 <!-- ~ End section ~ -->
722 <!-- ~~~~~ New section ~~~~~ -->
725 <title>Other Configuration Options</title>
728 This part of the configuration file contains options that control how
729 <application>Junkbuster</application> operates.
733 <quote>Admin-address</quote> should be set to the email address of the proxy
734 administrator. It is used in many of the proxy-generated pages. Default:
742 <emphasis>#admin-address fill@me.in.please</emphasis>
749 <quote>Proxy-info-url</quote> can be set to a URL that contains more info
750 about this <application>Junkbuster</application> installation, it's
751 configuration and policies. It is used in many of the proxy-generated pages
752 and its use is highly recommended in multi-user installations, since your
753 users will want to know why certain content is blocked or modified. Default:
754 Don't show a link to online documentation.
761 <emphasis>proxy-info-url http://www.your-site.com/proxy.html</emphasis>
768 <quote>Listen-address</quote> specifies the address and port where
769 <application>Junkbuster</application> will listen for connections from your
770 Web browser. The default is to listen on the localhost port 8000, and
771 this is suitable for most users. (In your web browser, under proxy
772 configuration, list the proxy server as <quote>localhost</quote> and the
773 port as <quote>8000</quote>).
777 If you already have another service running on port 8000, or if you want to
778 serve requests from other machines (e.g. on your local network) as well, you
779 will need to override the default. The syntax is
780 <quote>listen-address [<ip-address>]:<port></quote>. If you leave
781 out the IP address, <application>junkbuster</application> will bind to all
782 interfaces (addresses) on your machine and may become reachable from the
783 Internet. In that case, consider using access control lists (acl's) (see
784 <quote>aclfile</quote> above), or a firewall.
788 For example, suppose you are running <application>Junkbuster</application> on
789 a machine which has the address 192.168.0.1 on your local private network
790 (192.168.0.0) and has another outside connection with a different address.
791 You want it to serve requests from inside only:
798 <emphasis>listen-address 192.168.0.1:8000</emphasis>
805 If you want it to listen on all addresses (including the outside
813 <emphasis>listen-address :8000</emphasis>
820 If you do this, consider using ACLs (see <quote>aclfile</quote> above). Note:
821 you will need to point your browser(s) to the address and port that you have
822 configured here. Default: localhost:8000 (127.0.0.1:8000).
826 The debug option sets the level of debugging information to log in the
827 logfile (and to the console in the Windows version). A debug level of 1 is
828 informative because it will show you each request as it happens. Higher
829 levels of debug are probably only of interest to developers.
836 debug 1 # GPC = show each GET/POST/CONNECT request
837 debug 2 # CONN = show each connection status
838 debug 4 # IO = show I/O status
839 debug 8 # HDR = show header parsing
840 debug 16 # LOG = log all data into the logfile
841 debug 32 # FRC = debug force feature
842 debug 64 # REF = debug regular expression filter
843 debug 128 # = debug fast redirects
844 debug 256 # = debug GIF deanimation
845 debug 512 # CLF = Common Log Format
846 debug 1024 # = debug kill popups
847 debug 4096 # INFO = Startup banner and warnings.
848 debug 8192 # ERROR = Non-fatal errors
855 It is <emphasis>highly recommended</emphasis> that you enable ERROR
856 reporting (debug 8192), at least until the next stable release.
860 The reporting of FATAL errors (i.e. ones which crash
861 <application>JunkBuster</application>) is always on and cannot be disabled.
865 If you want to use CLF (Common Log Format), you should set <quote>debug
866 512</quote> ONLY, do not enable anything else.
870 Multiple <quote>debug</quote> directives, are OK - they're logical-OR'd
878 <emphasis>debug 15 # same as setting the first 4 listed above</emphasis>
892 <emphasis>debug 1 # URLs</emphasis>
893 <emphasis>debug 4096 # Info</emphasis>
894 <emphasis>debug 8192 # Errors - *we highly recommended enabling this*</emphasis>
901 <application>Junkbuster</application> normally uses
902 <quote>multi-threading</quote>, a software technique that permits it to
903 handle many different requests simultaneously. In some cases you may wish to
904 disable this -- particularly if you're trying to debug a problem. The
905 <quote>single-threaded</quote> option forces
906 <application>Junkbuster</application> to handle requests sequentially.
907 Default: Multi-threaded mode.
914 <emphasis>#single-threaded</emphasis>
921 <quote>toggle</quote> allows you to temporarily disable all
922 <application>Junkbuster's</application> filtering. Just set <quote>toggle
927 The Windows version of <application>Junkbuster</application> puts an icon in
928 the system tray, which also allows you to change this option. If you
929 right-click on that icon (or select the <quote>Options</quote> menu), one
930 choice is <quote>Enable</quote>. Clicking on enable toggles
931 <application>Junkbuster</application> on and off. This is useful if you want
932 to temporarily disable <application>Junkbuster</application>, e.g., to access
933 a site that requires cookies which you would otherwise have blocked. This can also
934 be toggled via a web browser at the <application>Junkbuster</application>
935 internal address of <ulink url="http://i.j.b">http://i.j.b</ulink> on
940 <quote>toggle 1</quote> means <application>Junkbuster</application> runs
941 normally, <quote>toggle 0</quote> means that
942 <application>Junkbuster</application> becomes a non-anonymizing non-blocking
943 proxy. Default: 1 (on).
950 <emphasis>toggle 1</emphasis>
957 For content filtering, i.e. the <quote>+filter</quote> and
958 <quote>+deanimate-gif</quote> actions, it is neccessary that
959 <application>Junkbuster</application> buffers the entire document body.
960 This can be potentially dangerous, since a server could just keep sending
961 data indefinitely and wait for your RAM to exhaust. With nasty consequences.
965 The <application>buffer-limit</application> option lets you set the maximum
966 size in Kbytes that each buffer may use. When the documents buffer exceeds
967 this size, it is flushed to the client unfiltered and no further attempt to
968 filter the rest of it is made. Remember that there may multiple threads
969 running, which might require increasing the <quote>buffer-limit</quote>
970 Kbytes <emphasis>each</emphasis>, unless you have enabled
971 <quote>single-threaded</quote> above.
978 <emphasis>buffer-limit 4069</emphasis>
985 To enable the web-based <filename>ijb.action</filename> file editor set
986 <application>enable-edit-actions</application> to 1, or 0 to disable. Note
987 that you must have compiled <application>JunkBuster</application> with
988 support for this feature, otherwise this option has no effect. This

1042 <title>Access Control List (ACL)</title>
1044 Access controls are included at the request of some ISPs and systems
1045 administrators, and are not usually needed by individual users. Please note
1046 the warnings in the FAQ that this proxy is not intended to be a substitute
1047 for a firewall or to encourage anyone to defer addressing basic security
1052 If no access settings are specified, the proxy talks to anyone that
1053 connects. If any access settings file are specified, then the proxy
1054 talks only to IP addresses permitted somewhere in this file and not
1055 denied later in this file.
1059 Summary -- if using an ACL:
1064 Client must have permission to receive service.
1069 LAST match in ACL wins.
1074 Default behavior is to deny service.
1079 The syntax for an entry in the Access Control List is:
1086 ACTION SRC_ADDR[/SRC_MASKLEN] [ DST_ADDR[/DST_MASKLEN] ]
1093 Where the individual fields are:
1100 <emphasis>ACTION</emphasis> = <quote>permit-access</quote> or <quote>deny-access</quote>
1102 <emphasis>SRC_ADDR</emphasis> = client hostname or dotted IP address
1103 <emphasis>SRC_MASKLEN</emphasis> = number of bits in the subnet mask for the source
1105 <emphasis>DST_ADDR</emphasis> = server or forwarder hostname or dotted IP address
1106 <emphasis>DST_MASKLEN</emphasis> = number of bits in the subnet mask for the target
1114 The field separator (FS) is whitespace (space or tab).
1118 IMPORTANT NOTE: If the <application>junkbuster</application> is using a
1119 forwarder (see below) or a gateway for a particular destination URL, the
1120 <literal>DST_ADDR</literal> that is examined is the address of the forwarder
1121 or the gateway and <emphasis>NOT</emphasis> the address of the ultimate
1122 target. This is necessary because it may be impossible for the local
1123 <application>Junkbuster</application> to determine the address of the
1124 ultimate target (that's often what gateways are used for).
1128 Here are a few examples to show how the ACL features work:
1132 <quote>localhost</quote> is OK -- no DST_ADDR implies that
1133 <emphasis>ALL</emphasis> destination addresses are OK:
1140 <emphasis>permit-access localhost</emphasis>
1147 A silly example to illustrate permitting any host on the class-C subnet with
1148 <application>Junkbuster</application> to go anywhere:
1155 <emphasis>permit-access www.junkbusters.com/24</emphasis>
1162 Except deny one particular IP address from using it at all:
1169 <emphasis>deny-access ident.junkbusters.com</emphasis>
1176 You can also specify an explicit network address and subnet mask.
1177 Explicit addresses do not have to be resolved to be used.
1184 <emphasis>permit-access 207.153.200.0/24</emphasis>
1191 A subnet mask of 0 matches anything, so the next line permits everyone.
1198 <emphasis>permit-access 0.0.0.0/0</emphasis>
1205 Note, you <emphasis>cannot</emphasis> say:
1212 <emphasis>permit-access .org</emphasis>
1219 to allow all *.org domains. Every IP address listed must resolve fully.
1223 An ISP may want to provide a <application>Junkbuster</application> that is
1224 accessible by <quote>the world</quote> and yet restrict use of some of their
1225 private content to hosts on its internal network (i.e. its own subscribers).
1226 Say, for instance the ISP owns the Class-B IP address block 123.124.0.0 (a 16
1227 bit netmask). This is how they could do it:
1234 <emphasis>permit-access 0.0.0.0/0 0.0.0.0/0</emphasis> # other clients can go anywhere
1235 # with the following exceptions:
1237 <emphasis>deny-access</emphasis> 0.0.0.0/0 123.124.0.0/16 # block all external requests for
1238 # sites on the ISP's network
1240 <emphasis>permit 0.0.0.0/0 www.my_isp.com</emphasis> # except for the ISP's main
1243 <emphasis>permit 123.124.0.0/16 0.0.0.0/0</emphasis> # the ISP's clients can go
1251 Note that if some hostnames are listed with multiple IP addresses,
1252 the primary value returned by DNS (via gethostbyname()) is used. Default:
1253 Anyone can access the proxy.
1258 <!-- ~ End section ~ -->
1261 <!-- ~~~~~ New section ~~~~~ -->
1264 <title>Forwarding</title>
1267 This feature allows chaining of HTTP requests via multiple proxies.
1268 It can be used to better protect privacy and confidentiality when
1269 accessing specific domains by routing requests to those domains
1270 to a special purpose filtering proxy such as lpwa.com. Or to use
1271 a caching proxy to speed up browsing.
1275 It can also be used in an environment with multiple networks to route
1276 requests via multiple gateways allowing transparent access to multiple
1277 networks without having to modify browser configurations.
1281 Also specified here are SOCKS proxies. <application>Junkbuster</application>
1282 SOCKS 4 and SOCKS 4A. The difference is that SOCKS 4A will resolve the target
1283 hostname using DNS on the SOCKS server, not our local DNS client.
1287 The syntax of each line is:
1294 <emphasis>forward target_domain[:port] http_proxy_host[:port]</emphasis>
1295 <emphasis>forward-socks4 target_domain[:port] socks_proxy_host[:port] http_proxy_host[:port]</emphasis>
1296 <emphasis>forward-socks4a target_domain[:port] socks_proxy_host[:port] http_proxy_host[:port]</emphasis>
1303 If http_proxy_host is <quote>.</quote>, then requests are not forwarded to a
1304 HTTP proxy but are made directly to the web servers.
1308 Lines are checked in sequence, and the last match wins.
1312 There is an implicit line equivalent to the following, which specifies that
1313 anything not finding a match on the list is to go out without forwarding
1314 or gateway protocol, like so:
1321 <emphasis>forward .* . </emphasis># implicit
1328 In the following common configuration, everything goes to Lucent's LPWA,
1329 except SSL on port 443 (which it doesn't handle):
1336 <emphasis>forward .* lpwa.com:8000</emphasis>
1337 <emphasis>forward :443 .</emphasis>
1344 See the FAQ for instructions on how to automate the login procedure for LPWA.
1345 Some users have reported difficulties related to LPWA's use of
1346 <quote>.</quote> as the last element of the domain, and have said that this
1347 can be fixed with this:
1354 <emphasis>forward lpwa. lpwa.com:8000</emphasis>
1361 (NOTE: the syntax for specifiying target_domain has changed since the
1362 previous paragraph was written -- it will not work now. More information
1367 In this fictitious example, everything goes via an ISP's caching proxy,
1368 except requests to that ISP:
1375 <emphasis>forward .* caching.myisp.net:8000</emphasis>
1376 <emphasis>forward myisp.net .</emphasis>
1383 For the @home network, we're told the forwarding configuration is this:
1391 <emphasis>forward .* proxy:8080</emphasis>
1398 Also, we're told they insist on getting cookies and JavaScript, so you should
1399 add home.com to the cookie file. We consider JavaScript a security risk.
1400 Java need not be enabled.
1404 In this example direct connections are made to all <quote>internal</quote>
1405 domains, but everything else goes through Lucent's LPWA by way of the
1406 company's SOCKS gateway to the Internet.
1413 <emphasis>forward-socks4 .* lpwa.com:8000 firewall.my_company.com:1080</emphasis>
1414 <emphasis>forward my_company.com .</emphasis>
1421 This is how you could set up a site that always uses SOCKS but no forwarders:
1428 <emphasis>forward-socks4a .* . firewall.my_company.com:1080</emphasis>
1435 An advanced example for network administrators:
1439 If you have links to multiple ISPs that provide various special content to
1440 their subscribers, you can configure forwarding to pass requests to the
1441 specific host that's connected to that ISP so that everybody can see all
1442 of the content on all of the ISPs.
1446 This is a bit tricky, but here's an example:
1451 host-a has a PPP connection to isp-a.com. And host-b has a PPP connection to
1452 isp-b.com. host-a can run a <application>Junkbuster</application> proxy with
1453 forwarding like this:
1460 <emphasis>forward .* .</emphasis>
1461 <emphasis>forward isp-b.com host-b:8000</emphasis>
1468 host-b can run a <application>Junkbuster</application> proxy with forwarding
1476 <emphasis>forward .* .</emphasis>
1477 <emphasis>forward isp-a.com host-a:8000</emphasis>
1484 Now, <emphasis>anyone</emphasis> on the Internet (including users on host-a
1485 and host-b) can set their browser's proxy to <emphasis>either</emphasis>
1486 host-a or host-b and be able to browse the content on isp-a or isp-b.
1490 Here's another practical example, for University of Kent at
1491 Canterbury students with a network connection in their room, who
1492 need to use the University's Squid web cache.
1499 <emphasis>forward *. ssbcache.ukc.ac.uk:3128</emphasis> # Use the proxy, except for:
1500 <emphasis>forward .ukc.ac.uk . </emphasis> # Anything on the same domain as us
1501 <emphasis>forward * . </emphasis> # Host with no domain specified
1502 <emphasis>forward 129.12.*.* . </emphasis> # A dotted IP on our /16 network.
1503 <emphasis>forward 127.*.*.* . </emphasis> # Loopback address
1504 <emphasis>forward localhost.localdomain . </emphasis> # Loopback address
1505 <emphasis>forward www.ukc.mirror.ac.uk . </emphasis> # Specific host
1512 If you intend to chain <application>Junkbuster</application> and
1513 <application>squid</application> locally, then chain as
1514 <literal>browser -> squid -> junkbuster</literal> is the recommended way.
1518 Your squid configuration could then look like this:
1525 # Define junkbuster as parent cache
1526 <!-- per feedback from user...
1527 cache_peer 127.0.0.1 8000 parent 0 no-query
1529 cache_peer 127.0.0.1 parent 8000 0 no-query
1531 # Define ACL for protocol FTP
1534 # Do not forward ACL FTP to junkbuster
1535 always_direct allow FTP
1537 # Do not forward ACL CONNECT (https) to junkbuster
1538 always_direct allow CONNECT
1540 # Forward the rest to junkbuster
1541 never_direct allow all

1555 <title>Windows GUI Options</title>
1557 Removed references to Win32. HB 09/23/01
1560 <application>Junkbuster</application> has a number of options specific to the
1561 Windows GUI interface:
1565 If <quote>activity-animation</quote> is set to 1, the
1566 <application>Junkbuster</application> icon will animate when
1567 <quote>Junkbuster</quote> is active. To turn off, set to 0.
1574 <emphasis>activity-animation 1</emphasis>
1581 If <quote>log-messages</quote> is set to 1,
1582 <application>Junkbuster</application> will log messages to the console
1590 <emphasis>log-messages 1</emphasis>
1597 If <quote>log-buffer-size</quote> is set to 1, the size of the log buffer,
1598 i.e. the amount of memory used for the log messages displayed in the
1599 console window, will be limited to <quote>log-max-lines</quote> (see below).
1603 Warning: Setting this to 0 will result in the buffer to grow infinitely and
1604 eat up all your memory!
1611 <emphasis>log-buffer-size 1</emphasis>
1618 <application>log-max-lines</application> is the maximum number of lines held
1619 in the log buffer. See above.
1626 <emphasis>log-max-lines 200</emphasis>
1633 If <quote>log-highlight-messages</quote> is set to 1,
1634 <application>Junkbuster</application> will highlight portions of the log
1635 messages with a bold-faced font:
1642 <emphasis>log-highlight-messages 1</emphasis>
1649 The font used in the console window:
1656 <emphasis>log-font-name Comic Sans MS</emphasis>
1663 Font size used in the console window:
1670 <emphasis>log-font-size 8</emphasis>
1677 <quote>show-on-task-bar</quote> controls whether or not
1678 <application>Junkbuster</application> will appear as a button on the Task bar
1686 <emphasis>show-on-task-bar 0</emphasis>
1693 If <quote>close-button-minimizes</quote> is set to 1, the Windows close
1694 button will minimize <application>Junkbuster</application> instead of closing
1695 the program (close with the exit option on the File menu).
1702 <emphasis>close-button-minimizes 1</emphasis>
1709 The <quote>hide-console</quote> option is specific to the MS-Win console
1710 version of <application>JunkBuster</application>. If this option is used,

1733 <title>The Actions File</title>
1736 The <quote>ijb.action</quote> file (formerly
1737 <filename>actionsfile</filename>) is used to define what actions
1738 <application>Junkbuster</application> takes, and thus determines how images,
1739 cookies and various other aspects of HTTP content and transactions are
1740 handled. Images can be anything you want, including ads, banners, or just
1741 some obnoxious image that you would rather not see. Cookies can be accepted
1742 or rejected, or accepted only during the current browser session (i.e.
1743 not written to disk). Changes to <filename>ijb.action</filename> should
1744 be immediately visible to <application>Junkbuster</application> without
1745 the need to restart.
1749 To determine which actions apply to a request, the URL of the request is
1750 compared to all patterns in this file. Every time it matches, the list of
1751 applicable actions for the URL is incrementally updated. You can trace
1752 this process by visiting <ulink
1753 url="http://i.j.b/show-url-info">http://i.j.b/show-url-info</ulink>.
1757 The actions file can be edited with a browser by loading
1758 <ulink url="http://i.j.b/">http://i.j.b/</ulink>, and then select
1759 <quote>Edit Actions</quote>.
1763 There are four types of lines in this file: comments (begin with a
1764 <quote>#</quote> character), actions, aliases and patterns, all of which are
1765 explained below, as well as the configuration file syntax that
1766 <application>Junkbuster</application> understands.
1771 <!-- ~~~~~ New section ~~~~~ -->
1773 <title>URL Domain and Path Syntax</title>
1775 Generally, a pattern has the form <domain>/<path>, where both the
1776 <domain> and <path> part are optional. If you only specify a
1777 domain part, the <quote>/</quote> can be left out:
1781 <emphasis>www.example.com</emphasis> - is a domain only pattern and will match any request to
1782 <quote>www.example.com</quote>.
1786 <emphasis>www.example.com/</emphasis> - means exactly the same.
1790 <emphasis>www.example.com/index.html</emphasis> - matches only the single
1791 document <quote>/index.html</quote> on <quote>www.example.com</quote>.
1795 <emphasis>/index.html</emphasis> - matches the document <quote>/index.html</quote>, regardless of
1800 <emphasis>index.html</emphasis> - matches nothing, since it would be
1801 interpreted as a domain name and there is no top-level domain called
1802 <quote>.html</quote>.
1806 The matching of the domain part offers some flexible options: if the
1807 domain starts or ends with a dot, it becomes unanchored at that end.
1812 <emphasis>.example.com</emphasis> - matches any domain that <emphasis>ENDS</emphasis> in
1813 <quote>.example.com</quote>.
1817 <emphasis>www.</emphasis> - matches any domain that <emphasis>STARTS</emphasis> with
1822 Additionally, there are wildcards that you can use in the domain names
1823 themselves. They work pretty similar to shell wildcards: <quote>*</quote>
1824 stands for zero or more arbitrary characters, <quote>?</quote> stands for
1825 any single character. And you can define charachter classes in square
1826 brackets and they can be freely mixed:
1830 <emphasis>ad*.example.com</emphasis> - matches <quote>adserver.example.com</quote>,
1831 <quote>ads.example.com</quote>, etc but not <quote>sfads.example.com</quote>.
1835 <emphasis>*ad*.example.com</emphasis> - matches all of the above, and then some.
1839 <emphasis>.?pix.com</emphasis> - matches <quote>www.ipix.com</quote>,
1840 <quote>pictures.epix.com</quote>, <quote>a.b.c.d.e.upix.com</quote>, etc.
1844 <emphasis>www[1-9a-ez].example.com</emphasis> - matches <quote>www1.example.com</quote>,
1845 <quote>www4.example.com</quote>, <quote>wwwd.example.com</quote>,
1846 <quote>wwwz.example.com</quote>, etc., but <emphasis>not</emphasis>
1847 <quote>wwww.example.com</quote>.
1851 If <application>Junkbuster</application> was compiled with
1852 <quote>pcre</quote> support (default), Perl compatible regular expressions
1853 can be used. See the <filename>pcre/docs/</filename> direcory or <quote>man
1854 perlre</quote> (also available on <ulink
1855 url="http://www.perldoc.com/perl5.6/pod/perlre.html">http://www.perldoc.com/perl5.6/pod/perlre.html</ulink>)
1856 for details. A brief discussion of regular expressions is in the
1857 <link linkend="regex">Appendix</link>. For instance:
1861 <emphasis>/.*/advert[0-9]+\.jpe?g</emphasis> - would match a URL from any
1862 domain, with any path that includes <quote>advert</quote> followed
1863 immediately by one or more digits, then a <quote>.</quote> and ending in
1864 either <quote>jpeg</quote> or <quote>jpg</quote>. So we match
1865 <quote>example.com/ads/advert2.jpg</quote>, and
1866 <quote>www.example.com/ads/banners/advert39.jpeg</quote>, but not
1867 <quote>www.example.com/ads/banners/advert39.gif</quote> (no gifs in the
1872 Please note that matching in the path is case
1873 <emphasis>INSENSITIVE</emphasis> by default, but you can switch to case
1874 sensitive at any point in the pattern by using the
1875 <quote>(?-i)</quote> switch:
1879 <emphasis>www.example.com/(?-i)PaTtErN.*</emphasis> - will match only
1880 documents whose path starts with <quote>PaTtErN</quote> in
1881 <emphasis>exactly</emphasis> this capitalization.
1886 <!-- ~ End section ~ -->
1890 <!-- ~~~~~ New section ~~~~~ -->
1893 <title>Actions</title>
1895 Actions are enabled if preceded with a <quote>+</quote>, and disabled if
1896 preceded with a <quote>-</quote>. Actions are invoked by enclosing the
1897 action name in curly braces (e.g. {+some_action}), followed by a list of
1898 URLs to which the action applies. There are three classes of actions:
1906 Boolean (e.g. <quote>+/-block</quote>):
1912 <emphasis>{+name}</emphasis> # enable this action
1913 <emphasis>{-name}</emphasis> # disable this action
1923 Parameterized (e.g. <quote>+/-hide-user-agent</quote>):
1929 <emphasis>{+name{param}}</emphasis> # enable action and set parameter to <quote>param</quote>
1930 <emphasis>{-name}</emphasis> # disable action
1939 Multi-value (e.g. <quote>{+/-add-header{Name: value}}</quote>, <quote>{+/-wafer{name=value}}</quote>):
1945 <emphasis>{+name{param}}</emphasis> # enable action and add parameter <quote>param</quote>
1946 <emphasis>{-name{param}}</emphasis> # remove the parameter <quote>param</quote>
1947 <emphasis>{-name}</emphasis> # disable this action totally
1958 If nothing is specified in this file, no <quote>actions</quote> are taken.
1959 So in this case <application>JunkBuster</application> would just be a
1960 normal, non-blocking, non-anonymizing proxy. You must specifically
1961 enable the privacy and blocking features you need (although the
1962 provided default <filename>ijb.action</filename> file will
1963 give a good starting point).
1967 Later defined actions always over-ride earlier ones. For multi-valued
1968 actions, the actions are applied in the order they are specified.
1972 The list of valid <application>Junkbuster</application> <quote>actions</quote> are:
1980 Add the specified HTTP header, which is not checked for validity.
1981 You may specify this many times to specify many different headers:
1987 <emphasis>+add-header{Name: value}</emphasis>
1997 Block this URL totally.
2003 <emphasis>+block</emphasis>
2013 De-animate all animated GIF images, i.e. reduce them to their last frame.
2014 This will also shrink the images considerably (in bytes, not pixels!). If
2015 the option <quote>first</quote> is given, the first frame of the animation
2016 is used as the replacement. If <quote>last</quote> is given, the last frame
2017 of the animation is used instead, which propably makes more sense for most
2018 banner animations, but also has the risk of not showing the entire last
2019 frame (if it is only a delta to an earlier frame).
2025 <emphasis>+deanimate-gifs{last}</emphasis>
2026 <emphasis>+deanimate-gifs{first}</emphasis>
2035 <quote>+downgrade</quote> will downgrade HTTP/1.1 client requests to
2036 HTTP/1.0 and downgrade the responses as well. Use this action for servers
2037 that use HTTP/1.1 protocol features that
2038 <application>Junkbuster</application> doesn't handle well yet. HTTP/1.1
2039 is only partially implemented. Default is not to downgrade requests.
2045 <emphasis>+downgrade</emphasis>
2054 Many sites, like yahoo.com, don't just link to other sites. Instead, they
2055 will link to some script on their own server, giving the destination as a
2056 parameter, which will then redirect you to the final target. URLs resulting
2057 from this scheme typically look like:
2058 http://some.place/some_script?http://some.where-else.
2061 Sometimes, there are even multiple consecutive redirects encoded in the
2062 URL. These redirections via scripts make your web browing more traceable,
2063 since the server from which you follow such a link can see where you go to.
2064 Apart from that, valuable bandwidth and time is wasted, while your browser
2065 ask the server for one redirect after the other. Plus, it feeds the
2069 The <quote>+fast-redirects</quote> option enables interception of these
2070 requests by <application>Junkbuster</application>, who will cut off all but
2071 the last valid URL in the request and send a local redirect back to your
2072 browser without contacting the remote site.
2078 <emphasis>+fast-redirects</emphasis>
2087 Filter the website through the re_filterfile:
2093 <emphasis>+filter{filename}</emphasis>
2102 Block any existing X-Forwarded-for header, and do not add a new one:
2108 <emphasis>+hide-forwarded</emphasis>
2117 If the browser sends a <quote>From:</quote> header containing your e-mail
2118 address, this either completely removes the header (<quote>block</quote>), or
2119 changes it to the specified e-mail address.
2125 <emphasis>+hide-from{block}</emphasis>
2126 <emphasis>+hide-from{spam@sittingduck.xqq}</emphasis>
2135 Don't send the <quote>Referer:</quote> (sic) header to the web site. You
2136 can block it, forge a URL to the same server as the request (which is
2137 preferred because some sites will not send images otherwise) or set it to a
2138 constant string of your choice.
2144 <emphasis>+hide-referer{block}</emphasis>
2145 <emphasis>+hide-referer{forge}</emphasis>
2146 <emphasis>+hide-referer{http://nowhere.com}</emphasis>
2155 Alternative spelling of <quote>+hide-referer</quote>. It has the same
2156 parameters, and can be freely mixed with, <quote>+hide-referer</quote>.
2157 (<quote>referrer</quote> is the correct English spelling, however the HTTP
2158 specification has a bug - it requires it to be spelled <quote>referer</quote>.)
2164 <emphasis>+hide-referrer{...}</emphasis>
2173 Change the <quote>User-Agent:</quote> header so web servers can't tell your
2174 browser type. Warning! This breaks many web sites. Specify the
2175 user-agent value you want. Example, pretend to be using Netscape on
2182 <emphasis>+hide-user-agent{Mozilla (X11; I; Linux 2.0.32 i586)}</emphasis>
2189 Or to identify yourself explicitly as a <quote>Junkbuster</quote> user:
2195 <emphasis>+hide-user-agent{JunkBuster/1.0}</emphasis>
2200 (Don't change the version number from 1.0 - after all, why tell them?)
2207 <emphasis>+hide-user-agent{browser-type}</emphasis>
2217 Treat this URL as an image. This only matters if it's also <quote>+block</quote>ed,
2218 in which case a <quote>blocked</quote> image can be sent rather than a HTML page.
2219 See <quote>+image-blocker{}</quote> below for the control over what is actually sent.
2225 <emphasis>+image</emphasis>
2234 Decides what to do with URLs that end up tagged with <quote>{+block
2235 +image}</quote>. There are 4 options. <quote>-image-blocker</quote> will
2236 send a HTML <quote>blocked</quote> page, usually resulting in a
2237 <quote>broken image</quote> icon. <quote>+image-blocker{logo}</quote> will
2238 send a <quote>JunkBuster</quote> image.
2239 <quote>+image-blocker{blank}</quote> will send a 1x1 transparent GIF image.
2240 And finally, <quote>+image-blocker{http://xyz.com}</quote> will send a HTTP
2241 temporary redirect to the specified image. This has the advantage of the
2242 icon being being cached by the browser, which will speed up the display.
2248 <emphasis>+image-blocker{logo}</emphasis>
2249 <emphasis>+image-blocker{blank}</emphasis>
2250 <emphasis>+image-blocker{http://i.j.b/send-banner}</emphasis>
2259 By default (i.e. in the absence of a <quote>+limit-connect</quote>
2260 action), <application>Junkbuster</application> will only allow CONNECT
2261 requests to port 443, which is the standard port for https as a
2266 The CONNECT methods exists in HTTP to allow access to secure websites
2267 (https:// URLs) through proxies. It works very simply: the proxy
2268 connects to the server on the specified port, and then short-circuits
2269 its connections to the client <emphasis>and</emphasis> to the remote proxy.
2270 This can be a big security hole, since CONNECT-enabled proxies can
2271 be abused as TCP relays very easily.
2275 If you want to allow CONNECT for more ports than this, or want to forbid
2276 CONNECT altogether, you can specify a comma separated list of ports and
2277 port ranges (the latter using dashes, with the minimum defaulting to 0 and
2285 <emphasis>+limit-connect{443} # This is the default and need no be specified.</emphasis>
2286 <emphasis>+limit-connect{80,443} # Ports 80 and 443 are OK.</emphasis>
2287 <emphasis>+limit-connect{-3, 7, 20-100, 500-} # Port less than 3, 7, 20 to 100</emphasis>
2288 <emphasis> #and above 500 are OK.</emphasis>
2298 <quote>+no-compression</quote> prevents the website from compressing the
2299 data. Some websites do this, which can be a problem for
2300 <application>Junkbuster</application>, since <quote>+filter</quote>,
2301 <quote>+no-popup</quote> and <quote>+gif-deanimate</quote> will not work on
2302 compressed data. This will slow down connections to those websites,
2303 though. Default is <quote>nocompression</quote> is turned on.
2310 <emphasis>+nocompression</emphasis>
2319 If the website sets cookies, <quote>no-cookies-keep</quote> will make sure
2320 they are erased when you exit and restart your web browser. This makes
2321 profiling cookies useless, but won't break sites which require cookies so
2322 that you can log in for transactions. Default: on.
2328 <emphasis>+no-cookies-keep</emphasis>
2337 Prevent the website from reading cookies:
2343 <emphasis>+no-cookies-read</emphasis>
2352 Prevent the website from setting cookies:
2358 <emphasis>+no-cookies-set</emphasis>
2367 Filter the website through a built-in filter to disable those obnoxious
2368 JavaScript pop-up windows via window.open(), etc. The two alternative
2369 spellings are equivalent.
2375 <emphasis>+no-popup</emphasis>
2376 <emphasis>+no-popups</emphasis>
2385 This action only applies if you are using a <filename>jarfile</filename>
2386 for saving cookies. It sends a cookie to every site stating that you do not
2387 accept any copyright on cookies sent to you, and asking them not to track
2388 you. Of course, this is a (relatively) unique header they could use to
2395 <emphasis>+vanilla-wafer</emphasis>
2404 This allows you to add an arbitrary cookie. It can be specified multiple
2405 times in order to add as many cookies as you like.
2411 <emphasis>+wafer{name=value}</emphasis>
2422 The meaning of any of the above is reversed by preceding the action with a
2423 <quote>-</quote>, in place of the <quote>+</quote>.
2431 Turn off cookies by default, then allow a few through for specified sites:
2438 # Turn off all persistant cookies
2439 { +no-cookies-read }
2441 # Allow cookies for this browser session ONLY
2442 { +no-cookies-keep }
2444 # Execeptions to the above, sites that benefit from persistant cookies
2445 { -no-cookies-read }
2447 { -no-cookies-keep }
2454 # Alternative way of saying the same thing
2455 {-no-cookies-set -no-cookies-read -no-cookies-keep}
2464 Now turn off <quote>fast redirects</quote>, and then we allow two exceptions:
2474 # Reverse it for these two sites, which don't work right without it.
2476 www.ukc.ac.uk/cgi-bin/wac\.cgi\?
2484 Turn on page filtering, with one exception for sourceforge:
2491 # Run everything through the default filter file (<filename>re_filterfile</filename>):
2494 # But please don't re_filter code from sourceforge!
2496 .cvs.sourceforge.net
2503 Now some URLs that we want <quote>blocked</quote>, ie we won't see them.
2504 Many of these use regular expressions that will expand to match multiple
2514 /.*/(.*[-_.])?ads?[0-9]?(/|[-_.].*|\.(gif|jpe?g))
2515 /.*/(.*[-_.])?count(er)?(\.cgi|\.dll|\.exe|[?/])

2569 <title>Aliases</title>
2571 Custom <quote>actions</quote>, known to <application>Junkbuster</application>
2572 as <quote>aliases</quote>, can be defined by combining other <quote>actions</quote>.
2573 These can in turn be invoked just like the built-in <quote>actions</quote>.
2574 Currently, an alias can contain any character except space, tab, <quote>=</quote>,
2575 <quote>{</quote> or <quote>}</quote>. But please use only <quote>a</quote>-
2576 <quote>z</quote>, <quote>0</quote>-<quote>9</quote>, <quote>+</quote>, and
2577 <quote>-</quote>. Alias names are not case sensitive, and
2578 <emphasis>must be defined before anything</emphasis> else in the
2579 <filename>ijb.action</filename>file ! And there can only be one set of
2580 <quote>aliases</quote> defined.
2584 Now let's define a few aliases:
2591 # Useful customer aliases we can use later. These must come first!
2593 +no-cookies = +no-cookies-set +no-cookies-read
2594 -no-cookies = -no-cookies-set -no-cookies-read
2595 fragile = -block -no-cookies -filter -fast-redirects -hide-referer -no-popups
2596 shop = -no-cookies -filter -fast-redirects
2597 +imageblock = +block +image
2599 #For people who don't like to type too much: ;-)
2602 c2 = -no-cookies-set +no-cookies-read
2603 c3 = +no-cookies-set -no-cookies-read
2604 #... etc. Customize to your heart's content.
2611 Some examples using our <quote>shop</quote> and <quote>fragile</quote>
2619 # These sites are very complex and require
2620 # minimal interference.
2622 .office.microsoft.com
2623 .windowsupdate.microsoft.com
2626 # Shopping sites - still want to block ads.

2650 <title>The Filter File</title>
2652 The filter file defines what filtering of web pages
2653 <application>Junkbuster</application> does. The default filter file is
2654 <filename>re_filterfile</filename>, located in the config directory. In this
2655 file, <emphasis>any document content</emphasis>, whether viewable text or
2656 embedded non-visible content, can be changed.
2660 This file uses regular expressions to alter or remove any string in the
2661 target page. Some examples from the included default <filename>re_filterfile</filename>:
2665 Stop web pages from displaying annoying messages in the status bar by
2666 deleting such references:
2673 # The status bar is for displaying link targets, not pointless buzzwords.
2674 # Again, check it out on http://www.airport-cgn.de/.
2675 s/status='.*?';*//ig
2682 Just for kicks, replace any occurrence of <quote>Microsoft</quote> with
2683 <quote>MicroSuck</quote>:
2690 s/microsoft(?!.com)/MicroSuck/ig
2697 Kill those auto-refresh tags:
2704 # Kill refresh tags. I like to refresh myself. Manually.
2705 # check it out on http://www.airport-cgn.de/ and go to the arrivals page.

2719 <sect1 id="quickstart"><title>Quickstart to Using Junkbuster</title>
2721 Install package, then run and enjoy! <application>Junbuster</application>
2722 accepts only one command line option -- the configuration file to be
2723 used. Example Unix startup command:
2729 # /usr/sbin/junkbuster /etc/junkbuster/config
2735 An init script is provided for SuSE and Redhat.
2739 For for SuSE: /etc/rc.d/junkbuster start
2743 For RedHat: /etc/rc.d/init.d/junkbuster start
2748 If no configuration file is specified on the command line,
2749 <application>Junkbuster</application> will look for a file named
2750 <filename>config</filename> in the current directory. Except on Amiga where
2751 it will look for <filename>AmiTCP:db/junkbuster/config</filename> and Win32
2752 where it will try <filename>config.txt</filename>. If no file is specified
2753 on the command line and no default configuration file can be found,
2754 <application>Junkbuster</application> will fail to start.
2758 Be sure your browser is set to use the proxy which is by default at
2759 localhost, port 8000. With <application>Netscape</application> (and
2760 <application>Mozilla</application>), this can be set under <literal>Edit
2761 -> Preferences -> Advanced -> Proxies -> HTTP Proxy</literal>.
2762 For <application>Internet Explorer</application>: <literal>Tools >
2763 Internet Properties -> Connections -> LAN Setting</literal>. Then,
2764 check <quote>Use Proxy</quote> and fill in the appropriate info (Address:
2765 localhost, Port: 8000). Include if HTTPS proxy support too.
2769 The included default configuration files should give a reasonable starting
2770 point, though may be somewhat aggressive in blocking junk. You will probably
2771 want to keep an eye out for sites that require persistant cookies, and add these to
2772 <filename>ijb.action</filename> as needed. By default, most of these will
2773 be accepted only during the current browser session, until you add them to
2774 the configuration. If you want the browser to handle this instead, you will
2775 need to edit <filename>ijb.action</filename> and disable this feature. If you
2776 use more than one browser, it would make more sense to let
2777 <application>Junkbuster</application> handle this. In which case, the
2778 browser(s) should be set to accept all cookies.
2782 If a particular site shows problems loading properly, try adding it
2783 to the <literal>{fragile}</literal> section of
2784 <filename>ijb.action</filename>. This will turn off most actions for
2789 HTTP/1.1 support is not fully implemented. If browsers that
2790 support HTTP/1.1 (like <application>Mozilla</application> or recent versions
2791 of I.E.) experience problems, you might try to force HTTP/1.0 compatiblity.
2792 For Mozilla, look under <literal>Edit -> Preferences -> Debug ->
2793 Networking</literal>. Or set the <quote>+downgrade</quote> config option in
2794 <filename>ijb.action</filename>.
2798 After running <application>Junkbuster</application> for a while, you can
2799 start to fine tune the configuration to suit your personal, or site,
2800 preferences and requirements. There are many, many aspects that can
2801 be customized. <quote>Actions</quote> (as specified in <filename>ijb.action</filename>)
2802 can be adjusted by pointing your browser to
2803 <ulink url="http://i.j.b/">http://i.j.b/</ulink>,
2804 and then follow the link to <quote>edit the actions list</quote>.
2805 (This is an internal page and does not require Internet access.)
2809 In fact, various aspects of <application>Junkbuster</application>
2810 configuration can be viewed from this page, including
2811 current configuration parameters, source code version numbers,
2812 the browser's request headers, and <quote>actions</quote> that apply
2813 to a given URL. In addition to the <filename>ijb.action</filename> file
2814 editor mentioned above, <application>Junkbuster</application> can also
2815 be turned <quote>on</quote> and <quote>off</quote> from this page.
2819 If you encounter problems, please verify it is a
2820 <application>Junkbuster</application> bug, by disabling
2821 <application>Junkbuster</application>, and then trying the same page.
2822 Also, try another browser if possible to eliminate browser or site
2823 problems. Before reporting it as a bug, see if there is not a configuration
2824 option that is enabled that is causing the page not to load. You can
2825 then add an exception for that page or site. If a bug, please report it to

2959 <title>Regular Expressions</title>
2961 <application>Junkbuster</application> can use <quote>regular expressions</quote>
2962 in various config files. Assuming support for <quote>pcre</quote> (Perl
2963 Compatible Regular Expressions) is compiled in, which is the default. Such
2964 configuration directives do not require regular expressions, but they can be
2965 used to increase flexibility by matching a pattern with wildcards against
2970 If you are reading this, you probably don't understand what <quote>regular
2971 expressions</quote> are, or what they can do. So this will be a very brief
2972 introduction only. A full explanation would require a book ;-)
2976 <quote>Regular expressions</quote> is a way of matching one character
2977 expression against another to see if it matches or not. One of the
2978 <quote>expressions</quote> is a literal string of readable characters
2979 (letter, numbers, etc), and the other is a complex string of literal
2980 characters combined with wildcards, and other special characters, called
2981 metacharacters. The <quote>metacharacters</quote> have special meanings and
2982 are used to build the complex pattern to be matched against. Perl Compatible
2983 Regular Expressions is an enhanced form of the regular expression language
2984 with backward compatibility.
2988 To make a simple analogy, we do something similar when we use wildcard
2989 characters when listing files with the <command>dir</command> command in DOS.
2990 <literal>*.*</literal> matches all filenames. The <quote>special</quote>
2991 character here is the asterik which matches any and all characters. We can be
2992 more specific and use <literal>?</literal> to match just individual
2993 characters. So <quote>dir file?.text</quote> would match
2994 <quote>file1.txt</quote>, <quote>file2.txt</quote>, etc. We are pattern
2995 matching, using a similar technique to <quote>regular expressions</quote>!
2999 Regular expressions do essentially the same thing, but are much, much more
3000 powerful. There are many more <quote>special characters</quote> and ways of
3001 building complex patterns however. Let's look at a few of the common ones,
3002 and then some examples:
3007 <emphasis>.</emphasis> - Matches any single character, e.g. <quote>a</quote>,
3008 <quote>A</quote>, <quote>4</quote>, <quote>:</quote>, or <quote>@</quote>.
3014 <emphasis>?</emphasis> - The preceding character or expression is matched ZERO or ONE
3021 <emphasis>+</emphasis> - The preceding character or expression is matched ONE or MORE
3028 <emphasis>*</emphasis> - The preceding character or expression is matched ZERO or MORE
3035 <emphasis>\</emphasis> - The <quote>escape</quote> character denotes that
3036 the following character should be taken literally. This is used where one of the
3037 special characters (e.g. <quote>.</quote>) needs to be taken literally and
3038 not as a special metacharacter.
3044 <emphasis>[]</emphasis> - Characters enclosed in brackets will be matched if
3045 any of the enclosed characters are encountered.
3051 <emphasis>()</emphasis> - Pararentheses are used to group a sub-expression,
3052 or multiple sub-expressions.
3058 <emphasis>|</emphasis> - The <quote>bar</quote> character works like an
3059 <quote>or</quote> conditional statement. A match is successful if the
3060 sub-expression on either side of <quote>|</quote> matches.
3066 <emphasis>s/string1/string2/g</emphasis> - This is used to rewrite strings of text.
3067 <quote>string1</quote> is replaced by <quote>string2</quote> in this
3073 These are just some of the ones you are likely to use when matching URLs with
3074 <application>Junkbuster</application>, and is a long way from a definitive
3075 list. This is enough to get us started with a few simple examples which may
3076 be more illuminating:
3080 <emphasis><literal>/.*/banners/.*</literal></emphasis> - A simple example
3081 that uses the common combination of <quote>.</quote> and <quote>*</quote> to
3082 denote any character, zero or more times. In other words, any string at all.
3083 So we start with a literal forward slash, then our regular expression pattern
3084 (<quote>.*</quote>) another literal forward slash, the string
3085 <quote>banners</quote>, another forward slash, and lastly another
3086 <quote>.*</quote>. We are building
3087 a directory path here. This will match any file with the path that has a
3088 directory named <quote>banners</quote> in it. The <quote>.*</quote> matches
3089 any characters, and this could conceivably be more forward slashes, so it
3090 might expand into a much longer looking path. For example, this could match:
3091 <quote>/eye/hate/spammers/banners/annoy_me_please.gif</quote>, or just
3092 <quote>/banners/annoying.html</quote>, or almost an infinite number of other
3093 possible combinations, just so it has <quote>banners</quote> in the path
3098 A now something a little more complex:
3102 <emphasis><literal>/.*/adv((er)?ts?|ertis(ing|ements?))?/</literal></emphasis> -
3103 We have several literal forward slashes again (<quote>/</quote>), so we are
3104 building another expression that is a file path statement. We have another
3105 <quote>.*</quote>, so we are matching against any conceivable sub-path, just so
3106 it matches our expression. The only true literal that <emphasis>must
3107 match</emphasis> our pattern is <application>adv</application>, together with
3108 the forward slashes. What comes after the <quote>adv</quote> string is the
3113 Remember the <quote>?</quote> means the preceding expression (either a
3114 literal character or anything grouped with <quote>(...)</quote> in this case)
3115 can exist or not, since this means either zero or one match. So
3116 <quote>((er)?ts?|ertis(ing|ements?))</quote> is optional, as are the
3117 individual sub-expressions: <quote>(er)</quote>,
3118 <quote>(ing|ements?)</quote>, and the <quote>s</quote>. The <quote>|</quote>
3119 means <quote>or</quote>. We have two of those. For instance,
3120 <quote>(ing|ements?)</quote>, can expand to match either <quote>ing</quote>
3121 <emphasis>OR</emphasis> <quote>ements?</quote>. What is being done here, is an
3122 attempt at matching as many variations of <quote>advertisement</quote>, and
3123 similar, as possible. So this would expand to match just <quote>adv</quote>,
3124 or <quote>advert</quote>, or <quote>adverts</quote>, or
3125 <quote>advertising</quote>, or <quote>advertisement</quote>, or
3126 <quote>advertisements</quote>. You get the idea. But it would not match
3127 <quote>advertizements</quote> (with a <quote>z</quote>). We could fix that by
3128 changing our regular expression to:
3129 <quote>/.*/adv((er)?ts?|erti(s|z)(ing|ements?))?/</quote>, which would then match
3134 <emphasis><literal>/.*/advert[0-9]+\.(gif|jpe?g)</literal></emphasis> - Again
3135 another path statement with forward slashes. Anything in the square brackets
3136 <quote>[]</quote> can be matched. This is using <quote>0-9</quote> as a
3137 shorthand expression to mean any digit one through nine. It is the same as
3138 saying <quote>0123456789</quote>. So any digit matches. The <quote>+</quote>
3139 means one or more of the preceding expression must be included. The preceding
3140 expression here is what is in the square brackets -- in this case, any digit
3141 one through nine. Then, at the end, we have a grouping: <quote>(gif|jpe?g)</quote>.
3142 This includes a <quote>|</quote>, so this needs to match the expression on
3143 either side of that bar character also. A simple <quote>gif</quote> on one side, and the other
3144 side will in turn match either <quote>jpeg</quote> or <quote>jpg</quote>,
3145 since the <quote>?</quote> means the letter <quote>e</quote> is optional and
3146 can be matched once or not at all. So we are building an expression here to
3147 match image GIF or JPEG type image file. It must include the literal
3148 string <quote>advert</quote>, then one or more digits, and a <quote>.</quote>
3149 (which is now a literal, and not a special character, since it is escaped
3150 with <quote>\</quote>), and lastly either <quote>gif</quote>, or
3151 <quote>jpeg</quote>, or <quote>jpg</quote>. Some possible matches would
3152 include: <quote>//advert1.jpg</quote>,
3153 <quote>/nasty/ads/advert1234.gif</quote>,
3154 <quote>/banners/from/hell/advert99.jpg</quote>. It would not match
3155 <quote>advert1.gif</quote> (no leading slash), or
3156 <quote>/adverts232.jpg</quote> (the expression does not include an
3157 <quote>s</quote>), or <quote>/advert1.jsp</quote> (<quote>jsp</quote> is not
3158 in the expression anywhere).
3162 <emphasis><literal>s/microsoft(?!.com)/MicroSuck/i</literal></emphasis> - This is
3163 a substitution. <quote>MicroSuck</quote> will replace any occurence of
3164 <quote>microsoft</quote>. The <quote>i</quote> at the end of the expression
3165 means ignore case. The <quote>(?!.com)</quote> means
3166 the match should fail if <quote>microsoft</quote> is followed by
3167 <quote>.com</quote>. In other words, this acts like a <quote>NOT</quote>
3168 modifier. In case this is a hyperlink, we don't want to break it ;-).
3172 We are barely scratching the surface of regular expressions here so that you
3173 can understand the default <application>Junkbuster</application>
3174 configuration files, and maybe use this knowledge to customize your own
3175 installation. There is much, much more that can be done with regular
3176 expressions. Now that you know enough to get started, you can learn more on
