I understand that, we use a very strict host access control list here on all Xserver based devices/products; I just thought it was interesting that xkill behaved in that manner. Initally I was under the impression that it would function like a graphical kill, but apparently that is not the case.

I don't know what possesed me to try this, but under Digital UNIX 5.0, as a normal user, I was able to set my DISPLAY to the IP address of another user who was running a seperate session, and run xkill.
xkill (like any other X client) uses the standard X access control scheme. Most likely, the other user had done an 'xhost +' or 'xhost +yourhost'. That's why xauth and friends exist, to stop games like this... -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech
