Using multiple X programs across SSH.
This is probably a borderline n00b question but recently I have taken interest in using the X window functionality of ssh. I can ssh into a remote machine but it seems that I can only run one application at a time. I can of course call xterm and type in my command to start a graphical program but it seems that I can only one one program at a time from the xterm. I'm currently using TWM due to memory restraints on an old Windows 98 machine.
Is there a UNIX/Linux built in command that will let me run multiple X GUI programs at once from a single ssh prompt?
Thanks in advance.
