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.

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_2.9.9_alpha
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-2.9.8-1.i686.rpm
252 /usr/src/redhat/SRPMS/junkbuster-2.9.9-1.src.rpm
256 To install, of course:
261 rpm -Uvv /usr/src/redhat/RPMS/i686/junkbuster-2.9.9-1.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-2.9.9-1.i686.rpm
296 /usr/src/packages/SRPMS/junkbuster-2.9.9-1.src.rpm
300 To install, of course:
305 rpm -Uvv /usr/src/packages/RPMS/i686/junkbuster-2.9.9-1.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:

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 need <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. For the
411 time being, there are only three default configuration files (this will
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.)
440 The <filename>re_filterfile</filename> file can be used to rewrite the raw
441 page content, including text as well as embedded HTML and JavaScript.
449 <filename>ijb.action</filename> and <filename>re_filterfile</filename>
450 can use Perl style regular expressions for maximum flexibility. All files use
451 the <quote><literal>#</literal></quote> character to denote a comment. Such
452 lines are not processed by <application>Junkbuster</application>. After
453 making any changes, restart <application>Junkbuster</application> in order
454 for the changes to take effect.
458 While under development, the configuration content is subject to change.
459 The below documentation may not be accurate by the time you read this.
460 Also, what constitutes a <quote>default</quote> setting, may change, so
461 please check all your configuration files on important issues.
464 <!-- ~~~~~ New section ~~~~~ -->
467 <title>The Main Configuration File</title>
469 Again, the main configuration file is named <filename>config</filename> on
470 Linux/Unix/BSD and OS/2, and <filename>config.txt</filename> on Windows.
471 Configuration lines consist of an initial keyword followed by a list of
472 values, all separated by whitespace (any number of spaces or tabs). For
480 <emphasis>blockfile blocklist.ini</emphasis>
487 Indicates that the blockfile is named <quote>blocklist.ini</quote>.
491 A <quote><literal>#</literal></quote> indicates a comment. Any part of a
492 line following a <quote><literal>#</literal></quote> is ignored, except if
493 the <quote><literal>#</literal></quote> is preceded by a
494 <quote><literal>\</literal></quote>.
498 Thus, by placing a <quote><literal>#</literal></quote> at the start of an
499 existing configuration line, you can make it a comment and it will be treated
500 as if it weren't there. This is called <quote>commenting out</quote> an
501 option and can be useful to turn off features: If you comment out the
502 <quote>logfile</quote> line, <application>junkbuster</application> will not
503 log to a file at all. Watch for the <quote>default:</quote> section in each
504 explanation to see what happens if the option is left unset (or commented
509 Long lines can be continued on the next line by using a
510 <quote><literal>\</literal></quote> as the very last character.
514 There are various aspects of <application>Junkbuster</application> behavior
519 <!-- ~~~~~ New section ~~~~~ -->
522 <title>Defining Other Configuration Files</title>
525 <application>Junkbuster</application> can use a number of other files to tell it
526 what ads to block, what cookies to accept, etc. This section of the
527 configuration file tells <application>Junkbuster</application> where to find
528 all those other files.
532 On <application>Windows</application>, <application>Junkbuster</application>
533 looks for these files in the same directory as the executable. On Unix and
534 OS/2, <application>Junkbuster</application> looks for these files in the current
535 working directory. In either case, an absolute path name can be used to
540 When development goes modular and multiuser, the blocker, filter, and
541 per-user config will be stored in subdirectories of <quote>confdir</quote>.
542 For now, only <filename>confdir/templates</filename> is used for storing HTML
543 templates for CGI results.
547 The location of the configuration files:
554 <emphasis>confdir /etc/junkbuster</emphasis> # No trailing /, please.
561 The directory where all logging (i.e. <filename>logfile</filename> and
562 <filename>jarfile</filename>) takes place. No trailing
563 <quote><literal>/</literal></quote>, please:
570 <emphasis>logdir /var/log/junkbuster</emphasis>
577 Note that all file specifications below are relative to
578 the above two directories!
582 The <quote>ijb.action</quote> file contains patterns to specify the actions to
583 apply to requests for each site. Default: Cookies to and from all
584 destinations are kept only during the current browser session (i.e. they
585 are not saved to disk). Popups are disabled for all sites. All sites are
586 filtered if <quote>re_filterfile</quote> specified. No sites are blocked. An
587 empty image is displayed for filtered ads and other images (formerly
588 <quote>tinygif</quote>). The syntax of this file is explained in detail <link
589 linkend="actionsfile">below</link>.
596 <emphasis>actionsfile ijb.action</emphasis>
603 The <quote>re_filterfile</quote> file contains content modification rules.
604 These rules permit powerful changes on the content of Web pages, e.g., you
605 could disable your favourite JavaScript annoyances, rewrite the actual
606 content, or just have some fun replacing <quote>Microsoft</quote> with
607 <quote>MicroSuck</quote> wherever it appears on a Web page. Default: No
608 content modification, or whatever the developers are playing with :-/
615 <emphasis>re_filterfile re_filterfile</emphasis>
622 The logfile is where all logging and error messages are written. The logfile
623 can be useful for tracking down a problem with
624 <application>Junkbuster</application> (e.g., it's not blocking an ad you
625 think it should block) but in most cases you probably will never look at it.
629 Your logfile will grow indefinitely, and you will probably want to
630 periodically remove it. On Unix systems, you can do this with a cron job
631 (see <quote>man cron</quote>). For Redhat, a <command>logrotate</command>
632 script has been included.
636 On SuSE Linux systems, you can place a line like <quote>/var/log/junkbuster.*
637 +1024k 644 nobody.nogroup</quote> in <filename>/etc/logfiles</filename>, with
638 the effect that cron.daily will automatically archive, gzip, and empty the
639 log, when it exceeds 1M size.
643 Default: Log to the a file named <filename>logfile</filename>.
644 Comment out to disable logging.
651 <emphasis>logfile logfile</emphasis>
658 The <quote>jarfile</quote> defines where
659 <application>Junkbuster</application> stores the cookies it intercepts. Note
660 that if you use a <quote>jarfile</quote>, it may grow quite large. Default:
661 Don't store intercepted cookies.
668 <emphasis>#jarfile jarfile</emphasis>
675 If you specify a <quote>trustfile</quote>,
676 <application>Junkbuster</application> will only allow access to sites that
677 are named in the trustfile. You can also mark sites as trusted referrers,
678 with the effect that access to untrusted sites will be granted, if a link
679 from a trusted referrer was used. The link target will then be added to the
680 <quote>trustfile</quote>. This is a very restrictive feature that typical
681 users most propably want to leave disabled. Default: Disabled, don't use the
689 <emphasis>#trustfile trust</emphasis>
696 If you use the trust mechanism, it is a good idea to write up some online
697 documentation about your blocking policy and to specify the URL(s) here. They
698 will appear on the page that your users receive when they try to access
699 untrusted content. Use multiple times for multiple URLs. Default: Don't
700 display links on the <quote>untrusted</quote> info page.
707 <emphasis>trust-info-url http://www.your-site.com/why_we_block.html</emphasis>
708 <emphasis>trust-info-url http://www.your-site.com/what_we_allow.html</emphasis>
716 <!-- ~ End section ~ -->
720 <!-- ~~~~~ New section ~~~~~ -->
723 <title>Other Configuration Options</title>
726 This part of the configuration file contains options that control how
727 <application>Junkbuster</application> operates.
731 <quote>Admin-address</quote> should be set to the email address of the proxy
732 administrator. It is used in many of the proxy-generated pages. Default:
740 <emphasis>#admin-address fill@me.in.please</emphasis>
747 <quote>Proxy-info-url</quote> can be set to a URL that contains more info
748 about this <application>Junkbuster</application> installation, it's
749 configuration and policies. It is used in many of the proxy-generated pages
750 and its use is highly recommended in multi-user installations, since your
751 users will want to know why certain content is blocked or modified. Default:
752 Don't show a link to online documentation.
759 <emphasis>proxy-info-url http://www.your-site.com/proxy.html</emphasis>
766 <quote>Listen-address</quote> specifies the address and port where
767 <application>Junkbuster</application> will listen for connections from your
768 Web browser. The default is to listen on the localhost port 8000, and
769 this is suitable for most users. (In your web browser, under proxy
770 configuration, list the proxy server as <quote>localhost</quote> and the
771 port as <quote>8000</quote>).
775 If you already have another service running on port 8000, or if you want to
776 serve requests from other machines (e.g. on your local network) as well, you
777 will need to override the default. The syntax is
778 <quote>listen-address [<ip-address>]:<port></quote>. If you leave
779 out the IP address, <application>junkbuster</application> will bind to all
780 interfaces (addresses) on your machine and may become reachable from the
781 Internet. In that case, consider using access control lists (acl's) (see
782 <quote>aclfile</quote> above), or a firewall.
786 For example, suppose you are running <application>Junkbuster</application> on
787 a machine which has the address 192.168.0.1 on your local private network
788 (192.168.0.0) and has another outside connection with a different address.
789 You want it to serve requests from inside only:
796 <emphasis>listen-address 192.168.0.1:8000</emphasis>
803 If you want it to listen on all addresses (including the outside
811 <emphasis>listen-address :8000</emphasis>
818 If you do this, consider using ACLs (see <quote>aclfile</quote> above). Note:
819 you will need to point your browser(s) to the address and port that you have
820 configured here. Default: localhost:8000 (127.0.0.1:8000).
824 The debug option sets the level of debugging information to log in the
825 logfile (and to the console in the Windows version). A debug level of 1 is
826 informative because it will show you each request as it happens. Higher
827 levels of debug are probably only of interest to developers.
834 debug 1 # GPC = show each GET/POST/CONNECT request
835 debug 2 # CONN = show each connection status
836 debug 4 # IO = show I/O status
837 debug 8 # HDR = show header parsing
838 debug 16 # LOG = log all data into the logfile
839 debug 32 # FRC = debug force feature
840 debug 64 # REF = debug regular expression filter
841 debug 128 # = debug fast redirects
842 debug 256 # = debug GIF deanimation
843 debug 512 # CLF = Common Log Format
844 debug 1024 # = debug kill popups
845 debug 4096 # INFO = Startup banner and warnings.
846 debug 8192 # ERROR = Non-fatal errors
853 It is <emphasis>highly recommended</emphasis> that you enable ERROR
854 reporting (debug 8192), at least until the next stable release.
858 The reporting of FATAL errors (i.e. ones which crash
859 <application>JunkBuster</application>) is always on and cannot be disabled.
863 If you want to use CLF (Common Log Format), you should set <quote>debug
864 512</quote> ONLY, do not enable anything else.
868 Multiple <quote>debug</quote> directives, are OK - they're logical-OR'd
876 <emphasis>debug 15 # same as setting the first 4 listed above</emphasis>
890 <emphasis>debug 1 # URLs</emphasis>
891 <emphasis>debug 4096 # Info</emphasis>
892 <emphasis>debug 8192 # Errors - *we highly recommended enabling this*</emphasis>
899 <application>Junkbuster</application> normally uses
900 <quote>multi-threading</quote>, a software technique that permits it to
901 handle many different requests simultaneously. In some cases you may wish to
902 disable this -- particularly if you're trying to debug a problem. The
903 <quote>single-threaded</quote> option forces
904 <application>Junkbuster</application> to handle requests sequentially.
905 Default: Multi-threaded mode.
912 <emphasis>#single-threaded</emphasis>
919 <quote>toggle</quote> allows you to temporarily disable all
920 <application>Junkbuster's</application> filtering. Just set <quote>toggle
925 The Windows version of <application>Junkbuster</application> puts an icon in
926 the system tray, which also allows you to change this option. If you
927 right-click on that icon (or select the <quote>Options</quote> menu), one
928 choice is <quote>Enable</quote>. Clicking on enable toggles
929 <application>Junkbuster</application> on and off. This is useful if you want
930 to temporarily disable <application>Junkbuster</application>, e.g., to access
931 a site that requires cookies which you would otherwise have blocked. This can also
932 be toggled via a web browser at the <application>Junkbuster</application>
933 internal address of <ulink url="http://i.j.b">http://i.j.b</ulink> on
938 <quote>toggle 1</quote> means <application>Junkbuster</application> runs
939 normally, <quote>toggle 0</quote> means that
940 <application>Junkbuster</application> becomes a non-anonymizing non-blocking
941 proxy. Default: 1 (on).
948 <emphasis>toggle 1</emphasis>
955 For content filtering, i.e. the <quote>+filter</quote> and
956 <quote>+deanimate-gif</quote> actions, it is neccessary that
957 <application>Junkbuster</application> buffers the entire document body.
958 This can be potentially dangerous, since a server could just keep sending
959 data indefinitely and wait for your RAM to exhaust. With nasty consequences.
963 The <application>buffer-limit</application> option lets you set the maximum
964 size in Kbytes that each buffer may use. When the documents buffer exceeds
965 this size, it is flushed to the client unfiltered and no further attempt to
966 filter the rest of it is made. Remember that there may multiple threads
967 running, which might require increasing the <quote>buffer-limit</quote>
968 Kbytes <emphasis>each</emphasis>, unless you have enabled
969 <quote>single-threaded</quote> above.
976 <emphasis>buffer-limit 4069</emphasis>
983 To enable the web-based <filename>ijb.action</filename> file editor set
984 <application>enable-edit-actions</application> to 1, or 0 to disable. Note
985 that you must have compiled <application>JunkBuster</application> with
986 support for this feature, otherwise this option has no effect. This
987 internal page can be reached at <ulink
988 url="http://i.j.b">http://i.j.b</ulink>.
992 Security note: If this is enabled, anyone who can use the proxy

1040 <title>Access Control List (ACL)</title>
1042 Access controls are included at the request of some ISPs and systems
1043 administrators, and are not usually needed by individual users. Please note
1044 the warnings in the FAQ that this proxy is not intended to be a substitute
1045 for a firewall or to encourage anyone to defer addressing basic security
1050 If no access settings are specified, the proxy talks to anyone that
1051 connects. If any access settings file are specified, then the proxy
1052 talks only to IP addresses permitted somewhere in this file and not
1053 denied later in this file.
1057 Summary -- if using an ACL:
1062 Client must have permission to receive service.
1067 LAST match in ACL wins.
1072 Default behavior is to deny service.
1077 The syntax for an entry in the Access Control List is:
1084 ACTION SRC_ADDR[/SRC_MASKLEN] [ DST_ADDR[/DST_MASKLEN] ]
1091 Where the individual fields are:
1098 <emphasis>ACTION</emphasis> = <quote>permit-access</quote> or <quote>deny-access</quote>
1100 <emphasis>SRC_ADDR</emphasis> = client hostname or dotted IP address
1101 <emphasis>SRC_MASKLEN</emphasis> = number of bits in the subnet mask for the source
1103 <emphasis>DST_ADDR</emphasis> = server or forwarder hostname or dotted IP address
1104 <emphasis>DST_MASKLEN</emphasis> = number of bits in the subnet mask for the target
1112 The field separator (FS) is whitespace (space or tab).
1116 IMPORTANT NOTE: If the <application>junkbuster</application> is using a
1117 forwarder (see below) or a gateway for a particular destination URL, the
1118 <literal>DST_ADDR</literal> that is examined is the address of the forwarder
1119 or the gateway and <emphasis>NOT</emphasis> the address of the ultimate
1120 target. This is necessary because it may be impossible for the local
1121 <application>Junkbuster</application> to determine the address of the
1122 ultimate target (that's often what gateways are used for).
1126 Here are a few examples to show how the ACL features work:
1130 <quote>localhost</quote> is OK -- no DST_ADDR implies that
1131 <emphasis>ALL</emphasis> destination addresses are OK:
1138 <emphasis>permit-access localhost</emphasis>
1145 A silly example to illustrate permitting any host on the class-C subnet with
1146 <application>Junkbuster</application> to go anywhere:
1153 <emphasis>permit-access www.junkbusters.com/24</emphasis>
1160 Except deny one particular IP address from using it at all:
1167 <emphasis>deny-access ident.junkbusters.com</emphasis>
1174 You can also specify an explicit network address and subnet mask.
1175 Explicit addresses do not have to be resolved to be used.
1182 <emphasis>permit-access 207.153.200.0/24</emphasis>
1189 A subnet mask of 0 matches anything, so the next line permits everyone.
1196 <emphasis>permit-access 0.0.0.0/0</emphasis>
1203 Note, you <emphasis>cannot</emphasis> say:
1210 <emphasis>permit-access .org</emphasis>
1217 to allow all *.org domains. Every IP address listed must resolve fully.
1221 An ISP may want to provide a <application>Junkbuster</application> that is
1222 accessible by <quote>the world</quote> and yet restrict use of some of their
1223 private content to hosts on its internal network (i.e. its own subscribers).
1224 Say, for instance the ISP owns the Class-B IP address block 123.124.0.0 (a 16
1225 bit netmask). This is how they could do it:
1232 <emphasis>permit-access 0.0.0.0/0 0.0.0.0/0</emphasis> # other clients can go anywhere
1233 # with the following exceptions:
1235 <emphasis>deny-access</emphasis> 0.0.0.0/0 123.124.0.0/16 # block all external requests for
1236 # sites on the ISP's network
1238 <emphasis>permit 0.0.0.0/0 www.my_isp.com</emphasis> # except for the ISP's main
1241 <emphasis>permit 123.124.0.0/16 0.0.0.0/0</emphasis> # the ISP's clients can go
1249 Note that if some hostnames are listed with multiple IP addresses,
1250 the primary value returned by DNS (via gethostbyname()) is used. Default:
1251 Anyone can access the proxy.
1256 <!-- ~ End section ~ -->
1259 <!-- ~~~~~ New section ~~~~~ -->
1262 <title>Forwarding</title>
1265 This feature allows chaining of HTTP requests via multiple proxies.
1266 It can be used to better protect privacy and confidentiality when
1267 accessing specific domains by routing requests to those domains
1268 to a special purpose filtering proxy such as lpwa.com. Or to use
1269 a caching proxy to speed up browsing.
1273 It can also be used in an environment with multiple networks to route
1274 requests via multiple gateways allowing transparent access to multiple
1275 networks without having to modify browser configurations.
1279 Also specified here are SOCKS proxies. <application>Junkbuster</application>
1280 SOCKS 4 and SOCKS 4A. The difference is that SOCKS 4A will resolve the target
1281 hostname using DNS on the SOCKS server, not our local DNS client.
1285 The syntax of each line is:
1292 <emphasis>forward target_domain[:port] http_proxy_host[:port]</emphasis>
1293 <emphasis>forward-socks4 target_domain[:port] socks_proxy_host[:port] http_proxy_host[:port]</emphasis>
1294 <emphasis>forward-socks4a target_domain[:port] socks_proxy_host[:port] http_proxy_host[:port]</emphasis>
1301 If http_proxy_host is <quote>.</quote>, then requests are not forwarded to a
1302 HTTP proxy but are made directly to the web servers.
1306 Lines are checked in sequence, and the last match wins.
1310 There is an implicit line equivalent to the following, which specifies that
1311 anything not finding a match on the list is to go out without forwarding
1312 or gateway protocol, like so:
1319 <emphasis>forward .* . </emphasis># implicit
1326 In the following common configuration, everything goes to Lucent's LPWA,
1327 except SSL on port 443 (which it doesn't handle):
1334 <emphasis>forward .* lpwa.com:8000</emphasis>
1335 <emphasis>forward :443 .</emphasis>
1342 See the FAQ for instructions on how to automate the login procedure for LPWA.
1343 Some users have reported difficulties related to LPWA's use of
1344 <quote>.</quote> as the last element of the domain, and have said that this
1345 can be fixed with this:
1352 <emphasis>forward lpwa. lpwa.com:8000</emphasis>
1359 (NOTE: the syntax for specifiying target_domain has changed since the
1360 previous paragraph was written -- it will not work now. More information
1365 In this fictitious example, everything goes via an ISP's caching proxy,
1366 except requests to that ISP:
1373 <emphasis>forward .* caching.myisp.net:8000</emphasis>
1374 <emphasis>forward myisp.net .</emphasis>
1381 For the @home network, we're told the forwarding configuration is this:
1389 <emphasis>forward .* proxy:8080</emphasis>
1396 Also, we're told they insist on getting cookies and JavaScript, so you should
1397 add home.com to the cookie file. We consider JavaScript a security risk.
1398 Java need not be enabled.
1402 In this example direct connections are made to all <quote>internal</quote>
1403 domains, but everything else goes through Lucent's LPWA by way of the
1404 company's SOCKS gateway to the Internet.
1411 <emphasis>forward-socks4 .* lpwa.com:8000 firewall.my_company.com:1080</emphasis>
1412 <emphasis>forward my_company.com .</emphasis>
1419 This is how you could set up a site that always uses SOCKS but no forwarders:
1426 <emphasis>forward-socks4a .* . firewall.my_company.com:1080</emphasis>
1433 An advanced example for network administrators:
1437 If you have links to multiple ISPs that provide various special content to
1438 their subscribers, you can configure forwarding to pass requests to the
1439 specific host that's connected to that ISP so that everybody can see all
1440 of the content on all of the ISPs.
1444 This is a bit tricky, but here's an example:
1449 host-a has a PPP connection to isp-a.com. And host-b has a PPP connection to
1450 isp-b.com. host-a can run a <application>Junkbuster</application> proxy with
1451 forwarding like this:
1458 <emphasis>forward .* .</emphasis>
1459 <emphasis>forward isp-b.com host-b:8000</emphasis>
1466 host-b can run a <application>Junkbuster</application> proxy with forwarding
1474 <emphasis>forward .* .</emphasis>
1475 <emphasis>forward isp-a.com host-a:8000</emphasis>
1482 Now, <emphasis>anyone</emphasis> on the Internet (including users on host-a
1483 and host-b) can set their browser's proxy to <emphasis>either</emphasis>
1484 host-a or host-b and be able to browse the content on isp-a or isp-b.
1488 Here's another practical example, for University of Kent at
1489 Canterbury students with a network connection in their room, who
1490 need to use the University's Squid web cache.
1497 <emphasis>forward *. ssbcache.ukc.ac.uk:3128</emphasis> # Use the proxy, except for:
1498 <emphasis>forward .ukc.ac.uk . </emphasis> # Anything on the same domain as us
1499 <emphasis>forward * . </emphasis> # Host with no domain specified
1500 <emphasis>forward 129.12.*.* . </emphasis> # A dotted IP on our /16 network.
1501 <emphasis>forward 127.*.*.* . </emphasis> # Loopback address
1502 <emphasis>forward localhost.localdomain . </emphasis> # Loopback address
1503 <emphasis>forward www.ukc.mirror.ac.uk . </emphasis> # Specific host
1510 If you intend to chain <application>Junkbuster</application> and
1511 <application>squid</application> locally, then chain as
1512 <literal>browser -> squid -> junkbuster</literal> is the recommended way.
1516 Your squid configuration could then look like this:
1523 # Define junkbuster as parent cache
1524 <!-- per feedback from user...
1525 cache_peer 127.0.0.1 8000 parent 0 no-query
1527 cache_peer 127.0.0.1 parent 8000 0 no-query
1529 # Define ACL for protocol FTP
1532 # Do not forward ACL FTP to junkbuster
1533 always_direct allow FTP
1535 # Do not forward ACL CONNECT (https) to junkbuster
1536 always_direct allow CONNECT
1538 # Forward the rest to junkbuster
1539 never_direct allow all

1553 <title>Windows GUI Options</title>
1555 Removed references to Win32. HB 09/23/01
1558 <application>Junkbuster</application> has a number of options specific to the
1559 Windows GUI interface:
1563 If <quote>activity-animation</quote> is set to 1, the
1564 <application>Junkbuster</application> icon will animate when
1565 <quote>Junkbuster</quote> is active. To turn off, set to 0.
1572 <emphasis>activity-animation 1</emphasis>
1579 If <quote>log-messages</quote> is set to 1,
1580 <application>Junkbuster</application> will log messages to the console
1588 <emphasis>log-messages 1</emphasis>
1595 If <quote>log-buffer-size</quote> is set to 1, the size of the log buffer,
1596 i.e. the amount of memory used for the log messages displayed in the
1597 console window, will be limited to <quote>log-max-lines</quote> (see below).
1601 Warning: Setting this to 0 will result in the buffer to grow infinitely and
1602 eat up all your memory!
1609 <emphasis>log-buffer-size 1</emphasis>
1616 <application>log-max-lines</application> is the maximum number of lines held
1617 in the log buffer. See above.
1624 <emphasis>log-max-lines 200</emphasis>
1631 If <quote>log-highlight-messages</quote> is set to 1,
1632 <application>Junkbuster</application> will highlight portions of the log
1633 messages with a bold-faced font:
1640 <emphasis>log-highlight-messages 1</emphasis>
1647 The font used in the console window:
1654 <emphasis>log-font-name Comic Sans MS</emphasis>
1661 Font size used in the console window:
1668 <emphasis>log-font-size 8</emphasis>
1675 <quote>show-on-task-bar</quote> controls whether or not
1676 <application>Junkbuster</application> will appear as a button on the Task bar
1684 <emphasis>show-on-task-bar 0</emphasis>
1691 If <quote>close-button-minimizes</quote> is set to 1, the Windows close
1692 button will minimize <application>Junkbuster</application> instead of closing
1693 the program (close with the exit option on the File menu).
1700 <emphasis>close-button-minimizes 1</emphasis>
1707 The <quote>hide-console</quote> option is specific to the MS-Win console
1708 version of <application>JunkBuster</application>. If this option is used,

1731 <title>The Actions File</title>
1734 The <quote>ijb.action</quote> file (formerly
1735 <filename>actionsfile</filename>) is used to define what actions
1736 <application>Junkbuster</application> takes, and thus determines how images,
1737 cookies and various other aspects of HTTP content and transactions are
1738 handled. Images can be anything you want, including ads, banners, or just
1739 some obnoxious image that you would rather not see. Cookies can be accepted
1740 or rejected, or accepted only during the current browser session (i.e.
1741 not written to disk).
1745 To determine which actions apply to a request, the URL of the request is
1746 compared to all patterns in this file. Every time it matches, the list of
1747 applicable actions for the URL is incrementally updated. You can trace
1748 this process by visiting <ulink
1749 url="http://i.j.b/show-url-info">http://i.j.b/show-url-info</ulink>.
1753 The actions file can be edited with a browser by loading
1754 <ulink url="http://i.j.b/">http://i.j.b/</ulink>, and then select
1755 <quote>Edit Actions</quote>.
1759 There are four types of lines in this file: comments (begin with a
1760 <quote>#</quote> character), actions, aliases and patterns, all of which are
1761 explained below, as well as the configuration file syntax that
1762 <application>Junkbuster</application> understands.
1767 <!-- ~~~~~ New section ~~~~~ -->
1769 <title>URL Domain and Path Syntax</title>
1771 Generally, a pattern has the form <domain>/<path>, where both the
1772 <domain> and <path> part are optional. If you only specify a
1773 domain part, the <quote>/</quote> can be left out:
1777 <emphasis>www.example.com</emphasis> - is a domain only pattern and will match any request to
1778 <quote>www.example.com</quote>.
1782 <emphasis>www.example.com/</emphasis> - means exactly the same.
1786 <emphasis>www.example.com/index.html</emphasis> - matches only the single
1787 document <quote>/index.html</quote> on <quote>www.example.com</quote>.
1791 <emphasis>/index.html</emphasis> - matches the document <quote>/index.html</quote>, regardless of
1796 <emphasis>index.html</emphasis> - matches nothing, since it would be
1797 interpreted as a domain name and there is no top-level domain called
1798 <quote>.html</quote>.
1802 The matching of the domain part offers some flexible options: if the
1803 domain starts or ends with a dot, it becomes unanchored at that end.
1808 <emphasis>.example.com</emphasis> - matches any domain that <emphasis>ENDS</emphasis> in
1809 <quote>.example.com</quote>.
1813 <emphasis>www.</emphasis> - matches any domain that <emphasis>STARTS</emphasis> with
1818 Additionally, there are wildcards that you can use in the domain names
1819 themselves. They work pretty similar to shell wildcards: <quote>*</quote>
1820 stands for zero or more arbitrary characters, <quote>?</quote> stands for
1821 any single character. And you can define charachter classes in square
1822 brackets and they can be freely mixed:
1826 <emphasis>ad*.example.com</emphasis> - matches <quote>adserver.example.com</quote>,
1827 <quote>ads.example.com</quote>, etc but not <quote>sfads.example.com</quote>.
1831 <emphasis>*ad*.example.com</emphasis> - matches all of the above, and then some.
1835 <emphasis>.?pix.com</emphasis> - matches <quote>www.ipix.com</quote>,
1836 <quote>pictures.epix.com</quote>, <quote>a.b.c.d.e.upix.com</quote>, etc.
1840 <emphasis>www[1-9a-ez].example.com</emphasis> - matches <quote>www1.example.com</quote>,
1841 <quote>www4.example.com</quote>, <quote>wwwd.example.com</quote>,
1842 <quote>wwwz.example.com</quote>, etc., but <emphasis>not</emphasis>
1843 <quote>wwww.example.com</quote>.
1847 If <application>Junkbuster</application> was compiled with
1848 <quote>pcre</quote> support (default), Perl compatible regular expressions
1849 can be used. See the <filename>pcre/docs/</filename> direcory or <quote>man
1850 perlre</quote> (also available on <ulink
1851 url="http://www.perldoc.com/perl5.6/pod/perlre.html">http://www.perldoc.com/perl5.6/pod/perlre.html</ulink>)
1852 for details. A brief discussion of regular expressions is in the
1853 <link linkend="regex">Appendix</link>. For instance:
1857 <emphasis>/.*/advert[0-9]+\.jpe?g</emphasis> - would match a URL from any
1858 domain, with any path that includes <quote>advert</quote> followed
1859 immediately by one or more digits, then a <quote>.</quote> and ending in
1860 either <quote>jpeg</quote> or <quote>jpg</quote>. So we match
1861 <quote>example.com/ads/advert2.jpg</quote>, and
1862 <quote>www.example.com/ads/banners/advert39.jpeg</quote>, but not
1863 <quote>www.example.com/ads/banners/advert39.gif</quote> (no gifs in the
1868 Please note that matching in the path is case
1869 <emphasis>INSENSITIVE</emphasis> by default, but you can switch to case
1870 sensitive at any point in the pattern by using the
1871 <quote>(?-i)</quote> switch:
1875 <emphasis>www.example.com/(?-i)PaTtErN.*</emphasis> - will match only
1876 documents whose path starts with <quote>PaTtErN</quote> in
1877 <emphasis>exactly</emphasis> this capitalization.
1882 <!-- ~ End section ~ -->
1886 <!-- ~~~~~ New section ~~~~~ -->
1889 <title>Actions</title>
1891 Actions are enabled if preceded with a <quote>+</quote>, and disabled if
1892 preceded with a <quote>-</quote>. Actions are invoked by enclosing the
1893 action name in curly braces (e.g. {+some_action}), followed by a list of
1894 URLs to which the action applies. There are three classes of actions:
1902 Boolean (e.g. <quote>+/-block</quote>):
1908 <emphasis>{+name}</emphasis> # enable this action
1909 <emphasis>{-name}</emphasis> # disable this action
1919 Parameterized (e.g. <quote>+/-hide-user-agent</quote>):
1925 <emphasis>{+name{param}}</emphasis> # enable action and set parameter to <quote>param</quote>
1926 <emphasis>{-name}</emphasis> # disable action
1935 Multi-value (e.g. <quote>{+/-add-header{Name: value}}</quote>, <quote>{+/-wafer{name=value}}</quote>):
1941 <emphasis>{+name{param}}</emphasis> # enable action and add parameter <quote>param</quote>
1942 <emphasis>{-name{param}}</emphasis> # remove the parameter <quote>param</quote>
1943 <emphasis>{-name}</emphasis> # disable this action totally
1954 If nothing is specified in this file, no <quote>actions</quote> are taken.
1955 So in this case <application>JunkBuster</application> would just be a
1956 normal, non-blocking, non-anonymizing proxy. You must specifically
1957 enable the privacy and blocking features you need (although the
1958 provided default <filename>ijb.action</filename> file will
1959 give a good starting point).
1963 Later defined actions always over-ride earlier ones. For multi-valued
1964 actions, the actions are applied in the order they are specified.
1968 The list of valid <application>Junkbuster</application> <quote>actions</quote> are:
1976 Add the specified HTTP header, which is not checked for validity.
1977 You may specify this many times to specify many different headers:
1983 <emphasis>+add-header{Name: value}</emphasis>
1993 Block this URL totally.
1999 <emphasis>+block</emphasis>
2009 De-animate all animated GIF images, i.e. reduce them to their last frame.
2010 This will also shrink the images considerably (in bytes, not pixels!). If
2011 the option <quote>first</quote> is given, the first frame of the animation
2012 is used as the replacement. If <quote>last</quote> is given, the last frame
2013 of the animation is used instead, which propably makes more sense for most
2014 banner animations, but also has the risk of not showing the entire last
2015 frame (if it is only a delta to an earlier frame).
2021 <emphasis>+deanimate-gifs{last}</emphasis>
2022 <emphasis>+deanimate-gifs{first}</emphasis>
2031 <quote>+downgrade</quote> will downgrade HTTP/1.1 client requests to
2032 HTTP/1.0 and downgrade the responses as well. Use this action for servers
2033 that use HTTP/1.1 protocol features that
2034 <application>Junkbuster</application> doesn't handle well yet. HTTP/1.1
2035 is only partially implemented. Default is not to downgrade requests.
2041 <emphasis>+downgrade</emphasis>
2050 Many sites, like yahoo.com, don't just link to other sites. Instead, they
2051 will link to some script on their own server, giving the destination as a
2052 parameter, which will then redirect you to the final target. URLs resulting
2053 from this scheme typically look like:
2054 http://some.place/some_script?http://some.where-else.
2057 Sometimes, there are even multiple consecutive redirects encoded in the
2058 URL. These redirections via scripts make your web browing more traceable,
2059 since the server from which you follow such a link can see where you go to.
2060 Apart from that, valuable bandwidth and time is wasted, while your browser
2061 ask the server for one redirect after the other. Plus, it feeds the
2065 The <quote>+fast-redirects</quote> option enables interception of these
2066 requests by <application>Junkbuster</application>, who will cut off all but
2067 the last valid URL in the request and send a local redirect back to your
2068 browser without contacting the remote site.
2074 <emphasis>+fast-redirects</emphasis>
2083 Filter the website through the re_filterfile:
2089 <emphasis>+filter{filename}</emphasis>
2098 Block any existing X-Forwarded-for header, and do not add a new one:
2104 <emphasis>+hide-forwarded</emphasis>
2113 If the browser sends a <quote>From:</quote> header containing your e-mail
2114 address, this either completely removes the header (<quote>block</quote>), or
2115 changes it to the specified e-mail address.
2121 <emphasis>+hide-from{block}</emphasis>
2122 <emphasis>+hide-from{spam@sittingduck.xqq}</emphasis>
2131 Don't send the <quote>Referer:</quote> (sic) header to the web site. You
2132 can block it, forge a URL to the same server as the request (which is
2133 preferred because some sites will not send images otherwise) or set it to a
2134 constant string of your choice.
2140 <emphasis>+hide-referer{block}</emphasis>
2141 <emphasis>+hide-referer{forge}</emphasis>
2142 <emphasis>+hide-referer{http://nowhere.com}</emphasis>
2151 Alternative spelling of <quote>+hide-referer</quote>. It has the same
2152 parameters, and can be freely mixed with, <quote>+hide-referer</quote>.
2153 (<quote>referrer</quote> is the correct English spelling, however the HTTP
2154 specification has a bug - it requires it to be spelled <quote>referer</quote>.)
2160 <emphasis>+hide-referrer{...}</emphasis>
2169 Change the <quote>User-Agent:</quote> header so web servers can't tell your
2170 browser type. Warning! This breaks many web sites. Specify the
2171 user-agent value you want. Example, pretend to be using Netscape on
2178 <emphasis>+hide-user-agent{Mozilla (X11; I; Linux 2.0.32 i586)}</emphasis>
2185 Or to identify yourself explicitly as a <quote>Junkbuster</quote> user:
2191 <emphasis>+hide-user-agent{JunkBuster/1.0}</emphasis>
2196 (Don't change the version number from 1.0 - after all, why tell them?)
2203 <emphasis>+hide-user-agent{browser-type}</emphasis>
2213 Treat this URL as an image. This only matters if it's also <quote>+block</quote>ed,
2214 in which case a <quote>blocked</quote> image can be sent rather than a HTML page.
2215 See <quote>+image-blocker{}</quote> below for the control over what is actually sent.
2221 <emphasis>+image</emphasis>
2230 Decides what to do with URLs that end up tagged with <quote>{+block
2231 +image}</quote>. There are 4 options. <quote>-image-blocker</quote> will
2232 send a HTML <quote>blocked</quote> page, usually resulting in a
2233 <quote>broken image</quote> icon. <quote>+image-blocker{logo}</quote> will
2234 send a <quote>JunkBuster</quote> image.
2235 <quote>+image-blocker{blank}</quote> will send a 1x1 transparent GIF image.
2236 And finally, <quote>+image-blocker{http://xyz.com}</quote> will send a HTTP
2237 temporary redirect to the specified image. This has the advantage of the
2238 icon being being cached by the browser, which will speed up the display.
2244 <emphasis>+image-blocker{logo}</emphasis>
2245 <emphasis>+image-blocker{blank}</emphasis>
2246 <emphasis>+image-blocker{http://i.j.b/send-banner}</emphasis>
2255 By default (i.e. in the absence of a <quote>+limit-connect</quote>
2256 action), <application>Junkbuster</application> will only allow CONNECT
2257 requests to port 443, which is the standard port for https as a
2262 The CONNECT methods exists in HTTP to allow access to secure websites
2263 (https:// URLs) through proxies. It works very simply: the proxy
2264 connects to the server on the specified port, and then short-circuits
2265 its connections to the client <emphasis>and</emphasis> to the remote proxy.
2266 This can be a big security hole, since CONNECT-enabled proxies can
2267 be abused as TCP relays very easily.
2271 If you want to allow CONNECT for more ports than this, or want to forbid
2272 CONNECT altogether, you can specify a comma separated list of ports and
2273 port ranges (the latter using dashes, with the minimum defaulting to 0 and
2281 <emphasis>+limit-connect{443} # This is the default and need no be specified.</emphasis>
2282 <emphasis>+limit-connect{80,443} # Ports 80 and 443 are OK.</emphasis>
2283 <emphasis>+limit-connect{-3, 7, 20-100, 500-} # Port less than 3, 7, 20 to 100</emphasis>
2284 <emphasis> #and above 500 are OK.</emphasis>
2294 <quote>+no-compression</quote> prevents the website from compressing the
2295 data. Some websites do this, which can be a problem for
2296 <application>Junkbuster</application>, since <quote>+filter</quote>,
2297 <quote>+no-popup</quote> and <quote>+gif-deanimate</quote> will not work on
2298 compressed data. This will slow down connections to those websites,
2299 though. Default is <quote>nocompression</quote> is turned on.
2306 <emphasis>+nocompression</emphasis>
2315 If the website sets cookies, <quote>no-cookies-keep</quote> will make sure
2316 they are erased when you exit and restart your web browser. This makes
2317 profiling cookies useless, but won't break sites which require cookies so
2318 that you can log in for transactions. Default: on.
2324 <emphasis>+no-cookies-keep</emphasis>
2333 Prevent the website from reading cookies:
2339 <emphasis>+no-cookies-read</emphasis>
2348 Prevent the website from setting cookies:
2354 <emphasis>+no-cookies-set</emphasis>
2363 Filter the website through a built-in filter to disable those obnoxious
2364 JavaScript pop-up windows via window.open(), etc. The two alternative
2365 spellings are equivalent.
2371 <emphasis>+no-popup</emphasis>
2372 <emphasis>+no-popups</emphasis>
2381 This action only applies if you are using a <filename>jarfile</filename>
2382 for saving cookies. It sends a cookie to every site stating that you do not
2383 accept any copyright on cookies sent to you, and asking them not to track
2384 you. Of course, this is a (relatively) unique header they could use to
2391 <emphasis>+vanilla-wafer</emphasis>
2400 This allows you to add an arbitrary cookie. It can be specified multiple
2401 times in order to add as many cookies as you like.
2407 <emphasis>+wafer{name=value}</emphasis>
2418 The meaning of any of the above is reversed by preceding the action with a
2419 <quote>-</quote>, in place of the <quote>+</quote>.
2427 Turn off cookies by default, then allow a few through for specified sites:
2434 # Turn off all persistant cookies
2435 { +no-cookies-read }
2437 # Allow cookies for this browser session ONLY
2438 { +no-cookies-keep }
2440 # Execeptions to the above, sites that benefit from persistant cookies
2441 { -no-cookies-read }
2443 { -no-cookies-keep }
2450 # Alternative way of saying the same thing
2451 {-no-cookies-set -no-cookies-read -no-cookies-keep}
2460 Now turn off <quote>fast redirects</quote>, and then we allow two exceptions:
2470 # Reverse it for these two sites, which don't work right without it.
2472 www.ukc.ac.uk/cgi-bin/wac\.cgi\?
2480 Turn on page filtering, with one exception for sourceforge:
2487 # Run everything through the default filter file (<filename>re_filterfile</filename>):
2490 # But please don't re_filter code from sourceforge!
2492 .cvs.sourceforge.net
2499 Now some URLs that we want <quote>blocked</quote>, ie we won't see them.
2500 Many of these use regular expressions that will expand to match multiple
2510 /.*/(.*[-_.])?ads?[0-9]?(/|[-_.].*|\.(gif|jpe?g))
2511 /.*/(.*[-_.])?count(er)?(\.cgi|\.dll|\.exe|[?/])

2565 <title>Aliases</title>
2567 Custom <quote>actions</quote>, known to <application>Junkbuster</application>
2568 as <quote>aliases</quote>, can be defined by combining other <quote>actions</quote>.
2569 These can in turn be invoked just like the built-in <quote>actions</quote>.
2570 Currently, an alias can contain any character except space, tab, <quote>=</quote>,
2571 <quote>{</quote> or <quote>}</quote>. But please use only <quote>a</quote>-
2572 <quote>z</quote>, <quote>0</quote>-<quote>9</quote>, <quote>+</quote>, and
2573 <quote>-</quote>. Alias names are not case sensitive, and
2574 <emphasis>must be defined before anything</emphasis> else in the
2575 <filename>ijb.action</filename>file ! And there can only be one set of
2576 <quote>aliases</quote> defined.
2580 Now let's define a few aliases:
2587 # Useful customer aliases we can use later. These must come first!
2589 +no-cookies = +no-cookies-set +no-cookies-read
2590 -no-cookies = -no-cookies-set -no-cookies-read
2591 fragile = -block -no-cookies -filter -fast-redirects -hide-referer -no-popups
2592 shop = -no-cookies -filter -fast-redirects
2593 +imageblock = +block +image
2595 #For people who don't like to type too much: ;-)
2598 c2 = -no-cookies-set +no-cookies-read
2599 c3 = +no-cookies-set -no-cookies-read
2600 #... etc. Customize to your heart's content.
2607 Some examples using our <quote>shop</quote> and <quote>fragile</quote>
2615 # These sites are very complex and require
2616 # minimal interference.
2618 .office.microsoft.com

2646 <title>The Filter File</title>
2648 The filter file defines what filtering of web pages
2649 <application>Junkbuster</application> does. The default filter file is
2650 <filename>re_filterfile</filename>, located in the config directory. In this
2651 file, <emphasis>any document content</emphasis>, whether viewable text or
2652 embedded non-visible content, can be changed.
2656 This file uses regular expressions to alter or remove any string in the
2657 target page. Some examples from the included default <filename>re_filterfile</filename>:
2661 Stop web pages from displaying annoying messages in the status bar by
2662 deleting such references:
2669 # The status bar is for displaying link targets, not pointless buzzwords.
2670 # Again, check it out on http://www.airport-cgn.de/.
2671 s/status='.*?';*//ig
2678 Just for kicks, replace any occurrence of <quote>Microsoft</quote> with
2679 <quote>MicroSuck</quote>:
2686 s/microsoft(?!.com)/MicroSuck/ig
2693 Kill those auto-refresh tags:
2700 # Kill refresh tags. I like to refresh myself. Manually.
2701 # check it out on http://www.airport-cgn.de/ and go to the arrivals page.
2703 s/<meta[^>]*http-equiv[^>]*refresh.*URL=([^>]*?)"?>/<link rev="x-refresh" href=$1>/i

2714 <!-- ~~~~~ New section ~~~~~ -->
2715 <sect1 id="quickstart"><title>Quickstart to Using Junkbuster</title>
2717 Install package, then run and enjoy! <application>Junbuster</application>
2718 accepts only one command line option -- the configuration file to be
2719 used. Example Unix startup command:
2725 # /usr/sbin/junkbuster /etc/junkbuster/config
2731 An init script is provided for SuSE and Redhat.
2735 For for SuSE: /etc/rc.d/junkbuster start
2739 For RedHat: /etc/rc.d/init.d/junkbuster start
2744 If no configuration file is specified on the command line,
2745 <application>Junkbuster</application> will look for a file named
2746 <filename>config</filename> in the current directory. Except on Amiga where
2747 it will look for <filename>AmiTCP:db/junkbuster/config</filename> and Win32
2748 where it will try <filename>config.txt</filename>. If no file is specified
2749 on the command line and no default configuration file can be found,
2750 <application>Junkbuster</application> will fail to start.
2754 Be sure your browser is set to use the proxy which is by default at
2755 localhost, port 8000. With <application>Netscape</application> (and
2756 <application>Mozilla</application>), this can be set under <literal>Edit
2757 -> Preferences -> Advanced -> Proxies -> HTTP Proxy</literal>.
2758 For <application>Internet Explorer</application>: <literal>Tools >
2759 Internet Properties -> Connections -> LAN Setting</literal>. Then,
2760 check <quote>Use Proxy</quote> and fill in the appropriate info (Address:
2761 localhost, Port: 8000). Include if HTTPS proxy support too.
2765 The included default configuration files should give a reasonable starting
2766 point, though may be somewhat aggressive in blocking junk. You will probably
2767 want to keep an eye out for sites that require persistant cookies, and add these to
2768 <filename>ijb.action</filename> as needed. By default, most of these will
2769 be accepted only during the current browser session, until you add them to
2770 the configuration. If you want the browser to handle this instead, you will
2771 need to edit <filename>ijb.action</filename> and disable this feature. If you
2772 use more than one browser, it would make more sense to let
2773 <application>Junkbuster</application> handle this. In which case, the
2774 browser(s) should be set to accept all cookies.
2778 If a particular site shows problems loading properly, try adding it
2779 to the <literal>{fragile}</literal> section of
2780 <filename>ijb.action</filename>. This will turn off most actions for
2785 HTTP/1.1 support is not fully implemented. If browsers that
2786 support HTTP/1.1 (like <application>Mozilla</application> or recent versions
2787 of I.E.) experience problems, you might try to force HTTP/1.0 compatiblity.
2788 For Mozilla, look under <literal>Edit -> Preferences -> Debug ->
2789 Networking</literal>. Or set the <quote>+downgrade</quote> config option in
2790 <filename>ijb.action</filename>.
2794 After running <application>Junkbuster</application> for a while, you can
2795 start to fine tune the configuration to suit your personal, or site,
2796 preferences and requirements. There are many, many aspects that can
2797 be customized. <quote>Actions</quote> (as specified in <filename>ijb.action</filename>)
2798 can be adjusted by pointing your browser to
2799 <ulink url="http://i.j.b/">http://i.j.b/</ulink>,
2800 and then follow the link to <quote>edit the actions list</quote>.
2801 (This is an internal page and does not require Internet access.)
2805 In fact, various aspects of <application>Junkbuster</application>
2806 configuration can be viewed from this page, including
2807 current configuration parameters, source code version numbers,
2808 the browser's request headers, and <quote>actions</quote> that apply
2809 to a given URL. In addition to the <filename>ijb.action</filename> file
2810 editor mentioned above, <application>Junkbuster</application> can also
2811 be turned <quote>on</quote> and <quote>off</quote> from this page.
2815 If you encounter problems, please verify it is a
2816 <application>Junkbuster</application> bug, by disabling
2817 <application>Junkbuster</application>, and then trying the same page.
2818 Also, try another browser if possible to eliminate browser or site
2819 problems. Before reporting it as a bug, see if there is not a configuration
2820 option that is enabled that is causing the page not to load. You can
2821 then add an exception for that page or site. If a bug, please report it to

2955 <title>Regular Expressions</title>
2957 <application>Junkbuster</application> can use <quote>regular expressions</quote>
2958 in various config files. Assuming support for <quote>pcre</quote> (Perl
2959 Compatible Regular Expressions) is compiled in, which is the default. Such
2960 configuration directives do not require regular expressions, but they can be
2961 used to increase flexibility by matching a pattern with wildcards against
2966 If you are reading this, you probably don't understand what <quote>regular
2967 expressions</quote> are, or what they can do. So this will be a very brief
2968 introduction only. A full explanation would require a book ;-)
2972 <quote>Regular expressions</quote> is a way of matching one character
2973 expression against another to see if it matches or not. One of the
2974 <quote>expressions</quote> is a literal string of readable characters
2975 (letter, numbers, etc), and the other is a complex string of literal
2976 characters combined with wildcards, and other special characters, called
2977 metacharacters. The <quote>metacharacters</quote> have special meanings and
2978 are used to build the complex pattern to be matched against. Perl Compatible
2979 Regular Expressions is an enhanced form of the regular expression language
2980 with backward compatibility.
2984 To make a simple analogy, we do something similar when we use wildcard
2985 characters when listing files with the <command>dir</command> command in DOS.
2986 <literal>*.*</literal> matches all filenames. The <quote>special</quote>
2987 character here is the asterik which matches any and all characters. We can be
2988 more specific and use <literal>?</literal> to match just individual
2989 characters. So <quote>dir file?.text</quote> would match
2990 <quote>file1.txt</quote>, <quote>file2.txt</quote>, etc. We are pattern
2991 matching, using a similar technique to <quote>regular expressions</quote>!
2995 Regular expressions do essentially the same thing, but are much, much more
2996 powerful. There are many more <quote>special characters</quote> and ways of
2997 building complex patterns however. Let's look at a few of the common ones,
2998 and then some examples:
3003 <emphasis>.</emphasis> - Matches any single character, e.g. <quote>a</quote>,
3004 <quote>A</quote>, <quote>4</quote>, <quote>:</quote>, or <quote>@</quote>.
3010 <emphasis>?</emphasis> - The preceding character or expression is matched ZERO or ONE
3017 <emphasis>+</emphasis> - The preceding character or expression is matched ONE or MORE
3024 <emphasis>*</emphasis> - The preceding character or expression is matched ZERO or MORE
3031 <emphasis>\</emphasis> - The <quote>escape</quote> character denotes that
3032 the following character should be taken literally. This is used where one of the
3033 special characters (e.g. <quote>.</quote>) needs to be taken literally and
3034 not as a special metacharacter.
3040 <emphasis>[]</emphasis> - Characters enclosed in brackets will be matched if
3041 any of the enclosed characters are encountered.
3047 <emphasis>()</emphasis> - Pararentheses are used to group a sub-expression,
3048 or multiple sub-expressions.
3054 <emphasis>|</emphasis> - The <quote>bar</quote> character works like an
3055 <quote>or</quote> conditional statement. A match is successful if the
3056 sub-expression on either side of <quote>|</quote> matches.
3062 <emphasis>s/string1/string2/g</emphasis> - This is used to rewrite strings of text.
3063 <quote>string1</quote> is replaced by <quote>string2</quote> in this
3069 These are just some of the ones you are likely to use when matching URLs with
3070 <application>Junkbuster</application>, and is a long way from a definitive
3071 list. This is enough to get us started with a few simple examples which may
3072 be more illuminating:
3076 <emphasis><literal>/.*/banners/.*</literal></emphasis> - A simple example
3077 that uses the common combination of <quote>.</quote> and <quote>*</quote> to
3078 denote any character, zero or more times. In other words, any string at all.
3079 So we start with a literal forward slash, then our regular expression pattern
3080 (<quote>.*</quote>) another literal forward slash, the string
3081 <quote>banners</quote>, another forward slash, and lastly another
3082 <quote>.*</quote>. We are building
3083 a directory path here. This will match any file with the path that has a
3084 directory named <quote>banners</quote> in it. The <quote>.*</quote> matches
3085 any characters, and this could conceivably be more forward slashes, so it
3086 might expand into a much longer looking path. For example, this could match:
3087 <quote>/eye/hate/spammers/banners/annoy_me_please.gif</quote>, or just
3088 <quote>/banners/annoying.html</quote>, or almost an infinite number of other
3089 possible combinations, just so it has <quote>banners</quote> in the path
3094 A now something a little more complex:
3098 <emphasis><literal>/.*/adv((er)?ts?|ertis(ing|ements?))?/</literal></emphasis> -
3099 We have several literal forward slashes again (<quote>/</quote>), so we are
3100 building another expression that is a file path statement. We have another
3101 <quote>.*</quote>, so we are matching against any conceivable sub-path, just so
3102 it matches our expression. The only true literal that <emphasis>must
3103 match</emphasis> our pattern is <application>adv</application>, together with
3104 the forward slashes. What comes after the <quote>adv</quote> string is the
3109 Remember the <quote>?</quote> means the preceding expression (either a
3110 literal character or anything grouped with <quote>(...)</quote> in this case)
3111 can exist or not, since this means either zero or one match. So
3112 <quote>((er)?ts?|ertis(ing|ements?))</quote> is optional, as are the
3113 individual sub-expressions: <quote>(er)</quote>,
3114 <quote>(ing|ements?)</quote>, and the <quote>s</quote>. The <quote>|</quote>
3115 means <quote>or</quote>. We have two of those. For instance,
3116 <quote>(ing|ements?)</quote>, can expand to match either <quote>ing</quote>
3117 <emphasis>OR</emphasis> <quote>ements?</quote>. What is being done here, is an
3118 attempt at matching as many variations of <quote>advertisement</quote>, and
3119 similar, as possible. So this would expand to match just <quote>adv</quote>,
3120 or <quote>advert</quote>, or <quote>adverts</quote>, or
3121 <quote>advertising</quote>, or <quote>advertisement</quote>, or
3122 <quote>advertisements</quote>. You get the idea. But it would not match
3123 <quote>advertizements</quote> (with a <quote>z</quote>). We could fix that by
3124 changing our regular expression to:
3125 <quote>/.*/adv((er)?ts?|erti(s|z)(ing|ements?))?/</quote>, which would then match
3130 <emphasis><literal>/.*/advert[0-9]+\.(gif|jpe?g)</literal></emphasis> - Again
3131 another path statement with forward slashes. Anything in the square brackets
3132 <quote>[]</quote> can be matched. This is using <quote>0-9</quote> as a
3133 shorthand expression to mean any digit one through nine. It is the same as
3134 saying <quote>0123456789</quote>. So any digit matches. The <quote>+</quote>
3135 means one or more of the preceding expression must be included. The preceding
3136 expression here is what is in the square brackets -- in this case, any digit
3137 one through nine. Then, at the end, we have a grouping: <quote>(gif|jpe?g)</quote>.
3138 This includes a <quote>|</quote>, so this needs to match the expression on
3139 either side of that bar character also. A simple <quote>gif</quote> on one side, and the other
3140 side will in turn match either <quote>jpeg</quote> or <quote>jpg</quote>,
3141 since the <quote>?</quote> means the letter <quote>e</quote> is optional and
3142 can be matched once or not at all. So we are building an expression here to
3143 match image GIF or JPEG type image file. It must include the literal
3144 string <quote>advert</quote>, then one or more digits, and a <quote>.</quote>
3145 (which is now a literal, and not a special character, since it is escaped
3146 with <quote>\</quote>), and lastly either <quote>gif</quote>, or
3147 <quote>jpeg</quote>, or <quote>jpg</quote>. Some possible matches would
3148 include: <quote>//advert1.jpg</quote>,
3149 <quote>/nasty/ads/advert1234.gif</quote>,
3150 <quote>/banners/from/hell/advert99.jpg</quote>. It would not match
3151 <quote>advert1.gif</quote> (no leading slash), or
3152 <quote>/adverts232.jpg</quote> (the expression does not include an
3153 <quote>s</quote>), or <quote>/advert1.jsp</quote> (<quote>jsp</quote> is not
3154 in the expression anywhere).
3158 <emphasis><literal>s/microsoft(?!.com)/MicroSuck/i</literal></emphasis> - This is
3159 a substitution. <quote>MicroSuck</quote> will replace any occurence of
3160 <quote>microsoft</quote>. The <quote>i</quote> at the end of the expression
3161 means ignore case. The <quote>(?!.com)</quote> means
3162 the match should fail if <quote>microsoft</quote> is followed by
3163 <quote>.com</quote>. In other words, this acts like a <quote>NOT</quote>
3164 modifier. In case this is a hyperlink, we don't want to break it ;-).
3168 We are barely scratching the surface of regular expressions here so that you
3169 can understand the default <application>Junkbuster</application>
3170 configuration files, and maybe use this knowledge to customize your own
3171 installation. There is much, much more that can be done with regular
3172 expressions. Now that you know enough to get started, you can learn more on
