I run a cluster of machines w/ only one display; I need to run lots of remote X apps. For performance, I think I need the X server listening on a TCP port - but Debian makes a big deal about the security implications. Have I any options besides A) using SSH, B) removing the "-nolisten tcp" option, (or C) avoiding remote X apps)?
Must I actually remove "-nolisten tcp" from "/etc/X11/xinit/xserverrc" and "/etc/X11/xdm/Xservers", or is there a "/etc/default" or dpkg switch I missed somewhere?
# - SECURITY NOTE: Always pass the "-nolisten tcp" option to the X # server, as shown in the examples below, unless you know you # need the X server listening on a TCP port. Omitting this # option can expose your X server to attacks from remote hosts. # Note also that SSH's X11 port-forwarding option works even with # X servers that do not listen on a TCP port, so you do not need # to remove the "-nolisten tcp" option for SSH's benefit.
Thanks!

VNC. Works well, and shouldn't chew up too much bandwidth on a local connection.
