There's no need for an application like that -- ssh ships with OSX.

Open a terminal and type ssh myserver.domain, If you want to port forward ssh -L3389:server:3389 myserver.domain
 
i know i can ssh from the terminal, but then i'd have to change my mac log in name to my actual log in name for where i ssh to (ie, school server).

is there a way to ssh under a different name without making a new mac account or changing my account name? hope that isn't too confusing.
