96 browser is configured for a different port than what
110 default. This has been changed to port 8118 now, due to a conflict
111 with NAS (Network Audio Service), which uses port 8000. If you haven't,
112 you need to change your browser to the new port number, or alternately

137 >5.2. I just added a new rule, but the steenkin ad is
138 still getting through. How?</H3
140 > If the ad had been displayed before you added its URL, it will probably be
141 held in the browser's cache for some time, so it will be displayed without
142 the need for any request to the server, and <SPAN
146 will not be in the picture. The best thing to do is try flushing the browser's
147 caches. And then try again.</P
149 > If this doesn't help, you probably have an error in the rule you
150 applied. Try pasting the full URL of the offending ad into <A
151 HREF="http://config.privoxy.org/show-url-info"
153 >http://config.privoxy.org/show-url-info</A
155 and see if it really matches your new rule.</P
164 >5.3. One of my favorite sites does not work with <SPAN
170 > First verify that it is indeed a <SPAN
174 by toggling off <SPAN
178 HREF="http://config.privoxy.org/toggle"
180 >http://config.privoxy.org/toggle</A
182 and then shift-reloading the problem page (i.e. holding down the shift key
183 while clicking reload. Alternatively, flush your browser's disk and memory
186 > If still a problem, go to <A
187 HREF="http://config.privoxy.org/show-url-info"
189 >http://config.privoxy.org/show-url-info</A
191 and paste the full URL of the page in question into the prompt. See which actions
192 are being applied to the URL, and which matches in which actions files are
193 responsible for that. Now, armed with this information, go to <A
194 HREF="http://config.privoxy.org/show-status"
196 >http://config.privoxy.org/show-status</A
198 and select the appropriate actions files for editing.</P
200 > You can now either look for a section which disables the actions that
201 you suspect to cause the problem and add a pattern for your site there,
202 or make up a completely new section for your site. In any case, the recommended
203 way is to disable only the prime suspect, reload the problem page, and only
204 if the problem persists, disable more and more actions until you have
205 identified the culprit. You may or may not want to turn the other actions
206 on again. Remember to flush your browser's caches in between any such changes!</P
208 > Alternately, if you are comfortable with a text editor, you can accomplish
209 the same thing by editing the appropriate actions file. Probably the easiest
210 way to deal with such problems when editing by hand is to add your
218 which is an alias that turns off most <SPAN
222 actions, but is also likely to turn off more actions then needed, and thus lower
223 your privacy and protection more than necessary, </P
225 > Troubleshooting actions is discussed in more detail in the <A

243 >5.4. After installing <SPAN
247 every time I start IE. What gives?</H3
249 > This is a quirk that effects the installation of
253 >, in conjunction with Internet Explorer and
254 Internet Connection Sharing on Windows 2000 and Windows XP. The symptoms may
255 appear to be corrupted or invalid DUN settings, or passwords.</P
257 > When setting up an NT based Windows system with
261 > you may find that things do not seem to be
262 doing what you expect. When you set your system up you will probably have set
263 up Internet Connection Sharing (ICS) with Dial up Networking (DUN) when
264 logged in with administrator privileges. You will probably have made this DUN
265 connection available to other accounts that you may have set-up on your
266 system. E.g. Mum or Dad sets up the system and makes accounts suitably
267 configured for the kids.</P
269 > When setting up <SPAN
272 > in this environment you
273 will have to alter the proxy set-up of Internet Explorer (IE) for the
274 specific DUN connection on which you wish to use
278 >. When you do this the ICS DUN set-up
279 becomes user specific. In this instance you will see no difference if you
280 change the DUN connection under the account used to set-up the connection.
281 However when you do this from another user you will notice that the DUN
282 connection changes to make available to "Me only". You will also find that
283 you have to store the password under each different user!</P
285 > The reason for this is that each user's set-up for IE is user specific. Each
286 set-up DUN connection and each LAN connection in IE store the settings for
287 each user individually. As such this enforces individual configurations
288 rather than common ones. Hence the first time you use a DUN connection after
289 re-booting your system it may not perform as you expect, and prompt you for
290 the password. Just set and save the password again and all should be OK.</P

301 >5.5. I cannot connect to any FTP sites. <SPAN
305 seems to be blocking me.</H3
310 > cannot act as a proxy for FTP traffic,
311 so do not configure your browser to use <SPAN
315 as an FTP proxy. The same is true for any protocol other than HTTP or HTTPS.
318 > Most browsers understand FTP as well as HTTP. If you connect to a site, with
321 >ftp://ftp.example.com</TT
322 >, your browser is making
323 an FTP connection, and not a HTTP connection. So while your browser may
327 > does not, and cannot proxy
338 >5.6. In Mac OSX, I can't configure Microsoft Internet Explorer to use
342 > as the HTTP proxy.</H3
344 > Microsoft Internet Explorer (in versions like 5.1) respects system-wide
345 network settings. In order to change the HTTP proxy, open System
346 Preferences, and click on the Network icon. In the settings pane that
347 comes up, click on the Proxies tab. Ensure the "Web Proxy (HTTP)" checkbox
348 is checked and enter <TT
351 > in the entry field.
355 > in the Port field. The next time you start
356 IE, it should reflect these values.
366 >5.7. In Mac OSX, I dragged the Privoxy folder to the trash in order to
367 uninstall it. Now the finder tells me I don't have sufficient privileges to
370 > Just dragging the <SPAN
373 > folder to the trash is
374 not enough to delete it. <SPAN
380 >uninstall.command</SPAN
381 > file that takes care of
382 these details. Open the trash, drag the <SPAN
384 >uninstall.command</SPAN
386 file out of the trash and double-click on it. You will be prompted for
387 confirmation and the administration password.
390 > The trash may still appear full after this command; emptying the trash
391 from the desktop should make it appear empty again.
401 >5.8. I get a completely blank page at one site. <SPAN
407 ><html><body></body></html></SPAN
412 > the page loads fine.</H3
414 > Chances are that the site suffers from a bug in
416 HREF="http://www.php.net/"
423 which results in empty pages being sent if the client explicitly requests
424 an uncompressed page, like <SPAN
428 This bug has been fixed in PHP 4.2.3.
431 > To find out if this is in fact the source of the problem, try adding
434 >-prevent-compression</TT
449 > # Make exceptions for ill-behaved sites:
451 {-prevent-compression}
457 > If that works, you may also want to report the problem to the
458 site's webmasters, telling them to use zlib.output_compression
459 instead of ob_gzhandler in their PHP applications (workaround)
460 or upgrade to PHP 4.2.3 or later (fix).
470 >5.9. Why am I getting a 503 Error (WSAECONNREFUSED) on every page?</H3
472 > More than likely this is a problem with the network stack. ZoneAlarm has
473 been reported to cause this symptom -- even if not running. The solution is
474 to either fight the ZA configuration, or uninstall ZoneAlarm, and then find
475 something better behaved in its place. Other firewall type products may
476 cause similar type problems if not configured correctly.
