How to manage multiple ssh sessions with ease on Mac OS X
There are two ways I manage, or have seen people manage, SSH data:

Good 'ole, command line, plain text, ssh_config file.

Create a file called config inside ~/.ssh. You can specify global parameters by putting them above any host declarations. When I started using MacPorts, I had to explicitly define a default SSH Private Key to use automatically when connecting, so as the very first line of the file I put;

IdentityFile ~/.ssh/id_rsa


When you define custom rules for hosts (and you can even use * as a wildcard), it looks something like this:

Host prod-*
  User jason
  Port 2222
  LocalForward 5901 localhost:5901
  IdentityFile ~/.ssh/work-id_rsa


Then when I run ssh prod-script for example, all the rest of the rules get applied automatically.



A lot of people who don't want to manually manage all their stuff in such a cumbersome manner quickly find JellyfiSSH. (Mac App Store Link. The same people also became very annoyed when it stopped being downloadable for free.)

JellyfiSSH gives you GUI access to almost everything that can be specified in the command line or ssh_config file. JellyfiSSH is just a configuration storage app for organization purposes, because it generates the commands based off the options you set and upon clicking connect, opens a new terminal window with all of your options defined on the command line. JellyfiSSH is not a terminal app on it's own.
