[ubuntu] Openssh server: Can't connect from remote

view story

http://ubuntuforums.org – Hi, sorry for the potentially stupid question. I have downloaded and installed openssh-server on a clean(just installed) ubuntu 12.04 install. I can connect just fine on the local lan with [email protected] but I don't know how/can't connect from a remote network. I attempted to connect to it with my android phone via the 3/4g network using the ip address (using connectbot). [email protected] but this just times out. Is there anyway to setup my ubuntu machine to accept connects from any network without getting a domain name? Thanks! (Hardware)
