95 Configuring the Internet Junkbuster is not easy. To help you get started, we
96 provide you with three different default configurations. The following table
97 shows you, which features are enabled in each configuration.

239 <sect3 id="browseconfig"> <title>Why can I change the configuration with a
240 browser? Does that not raise security issues?</title>
242 What I don't understand, is how I can browser edit the config file as a
243 regular user, while the whole /etc/junkbuster hierarchy belongs to the user
244 "junkbuster", with only 644 perms.
247 When you use the browser-based editor, JunkBuster itself is writing to the
248 config files. Because JunkBuster is running as the user "junkbuster", it can
249 update the config files.
252 If you don't like this, setting "enable-edit-actions 0" in the config file
253 will disable the browser-based editor. If you're that paranoid, you should
254 also consider setting "enable-remote-toggle 0" to prevent browser-based
255 enabling/disabling of JunkBuster.
258 Note that normally only local users can connect to JunkBuster, so this is not
259 (normally) a security problem.

267 <sect2 id="misc"><title>Misc</title>
269 <sect3 id="loadingtimes"><title>I noticed considerable
270 delays in page requests compared to the old IJB. What's wrong?</title>
272 Using the default filtering configuration, I noticed considerable delays in
273 page requests compared to the old IJB. Loading pages with large contents
274 seemed to take forever, then suddenly delivering all the content at once.
277 The whole content must be loaded in order to filter, and nothing is is
278 sent to the browser during this time. The loading time does not really
279 change in real numbers, but the feeling is different, because most
280 browsers are able to start rendering incomplete content, giving the
281 user a feeling of "it works".
284 To modify the content of a page (i.e. make frames resizeable again, etc.) and
285 not just replace ads, the Internet Junkbuster needs to download the entire
286 page first, do its content magic and then send the page to the browser.
291 <sect3 id="configurl"><title>What is the "http://i.j.b/"?</title>
293 Since JunkBuster sits between your web browser and the Internet, it can be
294 programmed to handle certain pages specially.
298 With recent versions of JunkBuster (version 2.9.x), you can get some
299 information about JunkBuster and change some settings by going to
300 http://i.j.b/ or, equivalently, http://ijbswa.sourceforge.net/config/
301 (Note that i.j.b is far easier to type but may not work in some
306 These pages are *not* forwarded to a server on the internet - instead they are
307 handled by a special web server which is built in to JunkBuster.
311 If you are not running JunkBuster, then http://i.j.b/ will fail, and
312 http://ijbswa.sourceforge.net/config/ will return a web page telling you
313 you're not running JunkBuster.
317 If you have version 2.0.2, then the equivalent is
318 http://example.com/show-proxy-args (but you get far less information, and you
319 should really consider upgrading to 2.9.x).
324 <sect3 id="badfiledesc"><title>I get the message 'Bad File Descriptor', why?</title>
330 <sect3 id="proxy-chaining"><title>How do I chain Junkbuster with other proxies
331 (e.g. squid)?</title>
337 <sect3 id="jointeam"><title>I would like to help you, what do I do?</title>
339 Well, helping the team is always a good idea. We welcome new developers,
340 RPM gurus or documentation makers. Simply get an account on sourceforge.net
341 and mail your id to the developer mailing list. Once we have added you to
342 the team, you'll have write access to the CVS repository, and together
343 we'll find a suitable task for you.
347 <sect3 id="blocklist"><title>Do you still maintain the blocklists?</title>
349 No. The format of the blocklists has changed significantly in the versions
350 2.9.x. Once we have released the new version, there will again be
351 blocklists that you can update automatically.
355 <sect3 id="newads"><title>How can I submit new ads?</title>
357 As of now, please discontinue to submit new ad blocking infos. Once we
358 have released the new version, there will again be a form on the website,
359 which you can use to contribute new ads.
363 <sect3 id="ip"><title>How can I hide my IP address?</title>
365 You cannot hide your IP address with Junkbuster or any other software, since
366 the server needs to know your IP address to send the answer to you.
369 Fortunately there are many publicly usable anonymous proxies out there, which
370 solve the problem by providing a further level of indirection between you and
371 the web server, shared by many people and thus letting your requests "drown"
372 in white noise of unrelated requests as far as user tracking is concerned.
375 Most of them will, however, log your IP address and make it available to the
376 authorities in case you abuse that anonymity for criminal purposes. In fact
377 you can't even rule out that some of them only exist to *collect* information
378 on (those suspicious) people with a more than average preference for privacy.
381 You can find a list of anonymous public proxies at <ulink
382 url="http://www.multiproxy.org/anon_list.htm">multiproxy.org</ulink> and many

390 <!-- contains an advertisement, it has to decide whether this advertisement is an -->
391 <!-- image or not. The Junkbuster uses the imagefile for that purpose. -->
