Bug 273927 – x11-apps/xdm-1.1.6: X server should not listen by default on 0.0.0.0:6000

• Status: RESOLVED DUPLICATE of bug 193044
• Product: Gentoo Security

[Description Martin Mokrejš 2009-06-12 21:55:38 UTC]

Hi,
  I found that by default my box is listening on port 6000 on all network interfaces:

# netstat -l -v -e -p -n
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       User       Inode      PID/Program name   
tcp        0      0 0.0.0.0:6000            0.0.0.0:*               LISTEN      0          30523842   19132/X 

I think it should be disabled or even better configurable in /etc/conf.d/xdm . At the moment I have disabled that in /etc/X11/xdm/Xservers by adding "-nolisten tcp" on the line defining local display :0.

One might want to have a look at:
http://bugs.gentoo.org/show_bug.cgi?id=171853

Jakub suggested to use ~/.xserverrc to change the listening behaviour. In my opinion the default should be -nolisten tcp.

@x11: any opinions on this?
