Edit /etc/hosts to assign names to IP addresses Example: in /etc/hosts add 192.168.1.25 client , then you can ssh <user>@client instead of user@192.168.1.25
to enable xterm uncomment " ForwardX11 no " and change it to "ForwardX11 yes"
To leave your ssh sessions running (i.e they dont time out) add ServerAliveInterval 300 in /etc/ssh/ssh_config on the client
