[How-To] Tor - The Onion Router for wl500g

[ecaddict]

If you'd like to automatically install tor & polipo just copy-paste as such the following script to your SSH terminal for the router:

#!/bin/sh
#written by ecaddict, distributed (conveyed) under GPL version 3 or any later version

START=/opt/etc/init.d/S99tor
PFILE=/opt/var/run/polipo.pid
LFILE=/opt/var/log/polipo.log
PCONF=/opt/etc/polipo/polipo.conf
#user editable part end

ipkg update
ipkg install tor polipo
mkdir -p /opt/etc/polipo

It will create the following files (save them if you have some of them already):
/opt/etc/tor/torrc
/opt/etc/polipo/polipo.conf
/opt/etc/init.d/S99tor

install.tar.gz

You'll need to edit /opt/etc/tor/torrc if you have preference for exiting via tor in some country or you wish to activate the relay (check the discussion).
In /opt/etc/polipo/polipo.conf you may wish to reduce logLevel.
For more polipo options please check http://www.pps.jussieu.fr/~jch/softw...po/polipo.html

My usual single line install instead:

cd /tmp && wget -O install.tar.gz "http://wl500g.info/attachment.php?attachmentid=8479&d=1322142484" && tar xvzf install.tar.gz && ./install.sh

In my experience tor/polipo can use quite some memory/CPU time so if you plan to run many other programs on the router as well you may want to consider using RT-N16 or 128MB memory upgraded WL-500gPv1/WL-500W.

If you'd like to disable automatic startup just re-name /opt/etc/init.d/S99tor to e.g. /opt/etc/init.d/DS99tor

Enjoy!
