ProxyChains is a UNIX program, that hooks network-related libc functions in dynamically linked programs via a preloaded DLL and redirects the connections through SOCKS4a/5 or HTTP proxies.
sudo apt-get install -y proxychains
proxychains4 -q -f config_file program_name [arguments]
-q makes proxychains quiet - this overrides the config setting
-f allows one to manually specify a configfile to use
for example : proxychains telnet somehost.com
Default location of the config file is /etc/proxychains4.conf. For example use SSH to build a Dynamic Port Forward.
