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

[Copter]

HowTo surf anonymously with TOR:

Tor, The Onion Router, is a network that helps to defend network surveillance. It hides the IP to avoid traffic analysis.

Further information:
https://www.torproject.org
http://en.wikipedia.org/wiki/Tor_%28...ity_network%29

!!Only use with activated swap!!

installing packets:

ipkg install tor
ipkg install polipo
ipkg install nano
ipkg install wget-ssl

To install wget-ssl, you might have to

ipkg remove wget

generate / configure config-files:

tor config:

cp /opt/etc/tor/torrc.sample /opt/etc/tor/torrc
nano /opt/etc/tor/torrc

## The directory for keeping all the keys/etc. By default, we store
## things in $HOME/.tor on Unix, and in Application Data\tor on Windows.
#DataDirectory @LOCALSTATEDIR@/lib/tor

has to be:

## The directory for keeping all the keys/etc. By default, we store
## things in $HOME/.tor on Unix, and in Application Data\tor on Windows.
DataDirectory /opt/var/lib/tor

Unfortunately, I havent found a way to reduce ram usage of tor, yet.

polipo config:

mkdir /opt/etc/polipo
cd /opt/etc/polipo/
wget https://svn.torproject.org/svn/torbrowser/trunk/build-scripts/config/polipo.conf --no-check-certificate
nano polipo.conf

Admin edit: svn repository has been moved to git
new link for config: https://gitweb.torproject.org/torbro...ig/polipo.conf

Following changes in polipo.conf:
(Full polipo.conf is attached)

### Basic configuration
### *******************

proxyAddress = "0.0.0.0"
# proxyAddress = "127.0.0.1"
allowedClients = 127.0.0.1, 192.168.1.61

### Memory
### ******

# Uncomment this if you want Polipo to use a ridiculously small amount
# of memory (a hundred C-64 worth or so):

#chunkHighMark = 819200 # 800kB Ram Usage in Bytes
#objectHighMark = 128

#chunkHighMark = 2097152 # 2M Ram Usage (=Ram x 1024 x 1024)
#objectHighMark = 768  

chunkHighMark = 4194304 # 4M Ram Usage
objectHighMark = 1536 

# Uncomment this if you've got plenty of memory:

# chunkHighMark = 50331648 # 48M Ram
# objectHighMark = 16384

#chunkHighMark = 67108864

### On-disk data
### ************
# diskCacheRoot = ""

allowedClients has to be 127.0.0.1 and all clients, who should be able to surf anonymously.
With 4 MB of Ram, polipo is much less CPU intensive than with only 800 kB.

Start tor and polipo:

tor & polipo -c /opt/etc/polipo/polipo.conf &

change the proxy settings of a browser on a connected PC to:
IPOFTHEROUTER:8118
and surfing is more anonym.

If you use the Firefox-Profile of JAP:
http://anonymous-proxy-servers.net/en/jondofox/download
you surf really anonym.


To help others to surf anonym, you can configure Tor as a Relay:

That for, you have to open a port in your firewall:

iptables -A INPUT -p tcp --dport 9001 -j ACCEPT

And activate the relay with the following changes in torrc:

ORPort 9001
RelayBandwidthRate 20 KBytes
RelayBandwidthBurst 30 KBytes

Cheers!
