Hi, As a random exercise in port-closing, I'm trying to stop X opening 6000. There was an article on rootprompt.org that suggested passing '-nolisten tcp' to the incantation to start X. Setup: /etc/rc.d/xdm starts X, since I'm using Helix Gnome I assume from this section of that script: case "$DISPLAYMANAGER" in kdm|kde|KDM|KDE) DISPLAYMANAGER=/opt/kde/bin/kdm ;; gdm|GDM|Gnome|GNOME) DISPLAYMANAGER=/opt/gnome/bin/gdm ;; *) DISPLAYMANAGER=/usr/X11R6/bin/xdm ;; esac that it eventually fires up gdm for me (I told it to use gdm during the Helix Gnome install). I tried passing '-nolisten tcp' to /opt/gnome/bin/gdm with no luck, in fact it would appear from gdm's behaviour when passed '--help' and '-?' it ignores command line parameters. I also don't have a man page for gdm and xdm's is less than helpful. Does anyone know how to do this?
