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:~$
