If you run for example eggdrop, psybnc, minecraft server or application running as a server and you don't know which ip you must use to connect then type command
sockstat –l4
to check on what ip address and port is listening
Another helpful commands
ifconfig – available IP on shell
vhost – this same but with shellmix vhosts
You can always change ip address in configuration file
Shellmix.com IP is not available on shell !
