Whilst there are numerous ways of keeping tabs of your SSH sessions, I found SSHMenu to be one of the easiest to manage and use. Whilst it is originally a GNOME panel applet, it can also be used outside of the GNOME desktop environment.
Installation is easy. Add the repository, "deb http://www.McLean.net.nz/debian stable contrib", on your /etc/apt/sources.list. Refresh apt-get and then invoke "sudo apt-get install sshmenu-gnome". If you prefer installing from source, you can get the source, too.
Configuration is straightforward.
Cool, eh?
