Nntlmaps; proxy software that allows you to authenticate via an MS Proxy Server

Ssh user config file

I got bored running command ssh -Y root@hostname everytime. So I created ssh config file my user. So my user connects remote computer with ssh command and allowed X11 forwarding.

edit ssh config file in your home directory
vi ~/.ssh/config

Add this line
User root
ForwardX11 yes


I use ssh passwordless login (ssh keygen) for remote computers. Also clusterssh for executing remote commands one time.

ClusterSSH controls a number of xterm windows via a single graphical console window to allow commands to be interactively run on multiple servers over an ssh connection.
