proxychains

proxychains allow you to route traffic using proxy servers. This is useful for routing traffic throihg applications that do not support proxy by default. For example, i use ssh through proxy chains.

To install proxychains on Ubuntu, run

apt install -y proxychains

Now you need to edit /etc/proxychains.conf and add your proxy servers.

sudo vi /etc/proxychains.conf 

On my computer, i use SSH tunnel to a sevrer on port 7878, so i added following to end of my proxychains.conf

socks5  127.0.0.1  7878

To text proxy proxychains, run

boby@sok-01:~$ curl checkip.amazonaws.com
59.92.71.53
boby@sok-01:~$ proxychains curl checkip.amazonaws.com
ProxyChains-3.1 (http://proxychains.sf.net)
|DNS-request| checkip.amazonaws.com 
|S-chain|-<>-127.0.0.1:7878-<><>-4.2.2.2:53-<><>-OK
|DNS-response| checkip.amazonaws.com is 34.193.115.2
|S-chain|-<>-127.0.0.1:7878-<><>-34.193.115.2:80-<><>-OK
51.38.246.115
boby@sok-01:~$ 

As you can see when using proxychains, you get a difernt IP as traffic get routed through proxy server specified in proxychains.conf

Proxychains show some connection info, you can hide this by editing proxychains.conf and uncommenting the line

# Quiet mode (no output from library)
#quiet_mode

With quite mode enabled, you will see

boby@sok-01:~$ proxychains curl checkip.amazonaws.com
ProxyChains-3.1 (http://proxychains.sf.net)
51.38.246.115
boby@sok-01:~$
