How to close a remote disconnected "xterm" window?
 

Using a xterm window to remotely log in and reboot a Redhat server causes the window to "hang" once the remote server reboots and I cannot close the window using Ctrl-D. Any ideas?

Open another terminal, find the pid (use the ps command) and kill the process (use the kill command). Or, if you prefer using your mouse, run xkill and click on the terminal.
