Hmm, I don't see a security tab in the preferences for X11.app using
OS X 10.4.

I had this problem along with a more annoying issue of having my
hostname automagically change based on where I connected to the net.  

I found notes via google suggesting that I edit /etc/hostconfig and
replace HOSTNAME=-AUTOMATIC- with my desired hostname.  I think this
resolved both issues for me.  YMMV.
