X is listening on port 6000?

My X server is listening on port 6000 and I simply can't find a good way to stop it from doing so!
I tried altering multiple config files (the startx script, Xservers script from the kdm configs) and still I have X listening!

(Of course there is still a firewall blocking reactions on that port)

Normaly a line like -nolistening tcp has to be added after defining the X server executable. This is a default setting but appearently not on my system.

What am I doing wrong?

Actually, the line "-nolisten tcp", try putting it in your /usr/X11R6/bin/startx, on the serverargs option.

/usr/X11R6/bin/startx

I've tried that before. Personaly I think the startx script is ommited whenever you use a graphical login manager like xdm, kdm, gdm etc... .

Kdm keeps it's config files in "/opt/kde/share/config/kdm/". According to the kde documentation one should alter the lines of the Xservers file. But these should contain the line -nolisten tcp by default. In my case (a fresh kde 3.4 install) the file did'nt so a changed it to:

# $Xorg: Xserv.ws.cpp,v 1.3 2000/08/17 19:54:17 cpqbld Exp $
#
# Xservers file, workstation prototype
#
# This file should contain an entry to start the server on the
# local display; if you have more than one display (not screen),
# you can add entries to the list (one per line).  If you also
# have some X terminals connected which do not support XDMCP,
# you can add them here as well.  Each X terminal line should
# look like:
#    XTerminalName:0 foreign
#
:0 local@tty1 /usr/X11R6/bin/X -nolisten tcp

### Don't change these two lines; they are hints for genkdmconf. ###
### Version 1.99 ###
:1 local reserve /usr/X11R6/bin/X -nolisten tcp :1 vt8
:2 local reserve /usr/X11R6/bin/X -nolisten tcp :2 vt9
:3 local reserve /usr/X11R6/bin/X -nolisten tcp :3 vt10

Still al of this makes no changes to the fact that X keeps listening on the 6000 port.
And since this can evolve into a security risk I want it to change. Quite odd behaviour really since it's should be ommited as default.

i think, like another recent post, you may need "-- -nolisten tcp" with 2 dashes in front of it... just guessing though

Re: X is listening on port 6000?

I don't understand what you want to do, but here's how I start any 'xinit' session:

startx[fce4] -- -nolisten tcp

or in your case,

:0 local@tty1 /usr/X11R6/bin/X vt7 -nolisten tcp

or to '/etc/X11/xdm/Xservers'

:0 local /usr/X11R6/bin/X -nolisten tcp

should do it.

The 'nolisten tcp' will effectively stop your X server from listening to remote clients.  You can use `nmap localhost` to verify it's not listening on that port.
