The Internet Junkbuster - Frequently Asked Questions

Applies to

SuSE Linux: Versions since 6.1
ijb

General information can be found in the section `Background Information'. The Internet Junkbuster is a trademark of Junkbusters Corp., the source code is provided under the terms of the GNU General Public Licence, courtesy of Junkbusters Corp.

Please note, that the Internet Junkbuster is not within the scope of the SuSE installation support. Please report bugs, suggestions, etc. to the below e-mail address. Support questions will not be answered.

Important:

A little bug sneaked in (SuSE Linux 6.2 only): Please change the file /sbin/init.d/ijb
Simply replace the line No. 17
su - nobody -c '/usr/sbin/junkbuster /etc/ijb/junkbstr.ini' &
with
su - nobody -c 'nohup /usr/sbin/junkbuster /etc/ijb/junkbstr.ini < /dev/null > /dev/null &'
After this change, the `failed'-messages when starting Junkbuster should no longer appear.
Thanks to Thorsten Bonow.

Request:

You want to install the Internet Junkbuster, start it up and surf the Web `filtered'.

Procedure:

  1. Install the package `ijb', series `n' using YaST
  2. Start up the Junkbuster using the command rcijb start
  3. Configure your Webbrowser to use `localhost:8000' as HTTP proxy-server
  4. Navigate to the URL http://internet.junkbuster.com/cgi-bin/show-proxy-args. This page will show, whether you're surfing through the Junkbuster or not
Hints:
rcijb start works only when used as user root. After having rebooted, the Junkbuster needs to be restarted. You can enable starting at boot-time with creating proper symlinks in the directories /sbin/init.d/rc2.d and /sbin/init.d/rc3.d. If you're using Netscape, HTTP proxy-servers can be configured in `Edit -> Preferences -> Advanced -> Proxies'. In this case, the proxy-server is your own machine (TCP-Port 8000). All configuration files of the Junkbuster are located in /etc/ijb. Further information about the Internet Junkbuster can be found on the Junkbusters Corporation Homepage.
The command ps aux | grep junkbuster
should create output similar the the following:
nobody 164 0.0 0.2 1276 296 ? S Apr 18 0:00 (junkbuster)
This output indicates a running Junkbuster (well, sleeping at that particular moment ;-)

Request:

Your Junkbuster is running, but all pages with banner ads look still the same as before (i.e. banner ads do not vanish or show up as `broken image'-icons).

Procedure:

You need to install an up-to-date blocklist.
Blocklists are available from many sites, e.g. waldherr.org (URL stated below). Download the blocklist and copy the file to /etc/ijb/sblock.ini (you may need to add a blank line at the end of the file). Afterwards use rcijb restart to restart the Junkbuster.

Background Information

The Internet Junkbuster is a non-cacheing HTTP proxy server. HTTP is the protocol used to `surf' the WorldWideWeb. HTTP is one of many protocols used in the Internet to transfer HTML-documents (and other files). `Non-cacheing' means that the Internet Junkbuster does not (in contrast to SQUID) store retrieved data locally to reduce network traffic.

You can use the Internet Junkbuster to

You can not use the Internet Junkbuster to block Spam (unsolicited bulk E-mail).

A detailed description of the technical merits and the configuration of the Internet Junkbuster can be found on the Junkbusters Corporation homepage (and you have access to the source code ;-).
