OpenSSH is a great means to protect your connection from being sniffed by others. However, this isn't always enough. Simply proving that you connected to a server is enough to get incriminated. Unfortunately, SSH doesn't provide a native way to obfuscate to whom it connects. Instead, a proxy server can be set up. And this is where TOR comes to play. This howto covers installing TOR on a Debian based system and setting up SSH to use TOR.
Installing TOR
First you should to add the TOR repository to your system. It's only necessary if there's no package in the default repositories.
Add the following line to your /etc/apt/sources.list file. You have to replace lenny with your distribution.
by type command
$ gedit /etc/apt/sources.list
and add following line :
deb http://mirror.noreply.org/pub/tor lenny main
$ apt-key adv --recv-keys --keyserver subkeys.pgp.net 0x94C09C7F
Update your sources.list by type
$ apt-get update
Install TOR :
$ apt-get install -y tor
If you want to use TOR with OpenSSH, you have to install another program called connect-proxy.
$ apt-get install -y connect-proxy
Setup OpenSSH to use TOR for all connections
However, this is not recommended, but here is how it works. Add the following block to the top of your ~/.ssh/config file.
Host *
CheckHostIP no
Compression yes
Protocol 2
ProxyCommand connect -4 -S localhost:9050 $(tor-resolve %h localhost:9050)
Set up OpenSSH to use TOR for a specific connection
I recommend using TOR only for a specific connection. All other connections won't be affected.
Add this block to your ~/.ssh/config. You have to replace mydomain with the host domain name or IP address and myaccount with your user name.
Host mydomain
HostName mydomain.com
User myaccount
CheckHostIP no
Compression yes
Protocol 2
Set up OpenSSH to use TOR for a bunch of connections
Instead of setting up TOR for every single connections, you can do this for a bunch of connections at once. Following example shows how it works.
Host anon_*
CheckHostIP no
Compression yes
Protocol 2
ProxyCommand connect -4 -S localhost:9050 $(tor-resolve %h localhost:9050) %p
Host anon_mydomain
HostName mydomain.com
User myaccount
Host anon_mydomain2
HostName mydomain2.com
User myaccount
Port 980
Finish....!!!
Happy Testing...!!
