Socat Port Forwarding Examples

gistfile1.txt

Example 1

socat TCP4-LISTEN:5010,reuseaddr,fork PROXY:109.185.139.177:www.zerohedge.com:80,proxyport=65103



In our case

ping www.zerohedge.com


34.199.177.156 is the ip of zerohedge.com

note it somewhere

echo    "127.0.0.1 www.zerohedge.com" >> /etc/hosts





Port 5010 must be replaced with the real port used by the app, it's just a placeholder




socat TCP4-LISTEN:5010,reuseaddr,fork PROXY:109.185.139.177:34.199.177.156:80,proxyport=65103





This way we trick the OS into believing that our node is zerohedge and this way we do not have to rewrite code.

Parameters in the examples must be replaced accordingly.


Example 2

Example of socat listening to multiple ports:
echo -n 3392 3393 3394 | xargs -d ' ' -I% bash -c 'socat TCP4-LISTEN:%,fork TCP4:192.168.10.102:% &'
