Xserver checking for reverse lookup
RHEL 5.2
Any one familiar with disabling the ip check by the Xserver.
I have scenario that my DNS server has an IP(x.x.x.x=dupclient) address which is not getting cleaned up. But the same IP is currently being used by another user(x.x.x.x=client) So when the connection is made to the linux server from the client and the linux server checks back(client=x.x.x.x) the from where the connection is currently made. But the linux sending communication to "dupclient" instead of "client" as linux server is resolving that way. But this is not happening for an HP-UX 11.11 server.The Xserver on HPUX box does not try a reverse lookup and hence no conflicts. My guess is the LINUX xserevr code has some extra security feature and that is want i want to disable if possible.

Re: Xserver checking for reverse lookup
Shalom,
Linux is a little more secure out of the box.
Check /etc/X11/xorg.conf
These files:
/etc/X11/xinit
Xclients xinitrc xinitrc.d xinputrc
Xclients.d xinitrc-common xinput.d Xsession
[root@bersheva xinit]# pwd
Also the gdm files.
-rw-r--r-- 1 root root 2597 May 28 2008 custom.conf
drwxr-xr-x 2 root root 4096 Feb 14 20:13 Init
-rw-r--r-- 1 root root 4048 May 28 2008 locale.alias
drwxr-xr-x 2 root root 4096 Feb 14 20:13 modules
drwxr-xr-x 2 root root 4096 Feb 14 20:13 PostLogin
drwxr-xr-x 2 root root 4096 Feb 14 20:13 PostSession
drwxr-xr-x 2 root root 4096 Feb 14 20:13 PreSession
-rw-r--r-- 1 root root 71 May 28 2008 securitytokens.conf
-rwxr-xr-x 1 root root 5536 May 28 2008 XKeepsCrashing
lrwxrwxrwx 1 root root 21 Feb 14 20:13 Xsession -> ../X11/xinit/Xsession
[root@bersheva gdm]# pwd
/etc/gdm
This is defined and documented in English language documentation in the configuration files.
