I have a CentOS server at home and want to view the X display on a laptop running Ubuntu, and not having much success. Here's what's been tried so far: I ran this command on the CentOS server: export DISPLAY=192.168.0.18:0.0 And ran this command on the Ubuntu laptop: xauth +192.168.0.2 When I try to run, say, xclock on the Ubuntu laptop, this is the error message I'm getting: [root at centos-ws ~]# xclock Error: Can't open display: 192.168.0.18:0.0 I'm assuming there's an important little detail I'm missing somewhere, but don't know what. Any suggestions? Paul
