Thanks to everyone, especially Nigel. I can now run the graphics from my mac onto the head node. Next step is to see if I can get the compute nodes to display the image. Short synopsis of the steps: On the head node: 1. Edit /etc/X11/fs/config to a. include the paths to the Mathematic fonts under catalogue= b. Comment out #no-listen = tcp 2. Restart xfs "service xfs restart" 3. Edit the iptables to allow tcp connections to port 7100 4. Restart iptables "service iptables restart" On the local mac where ted is the head node on the server xfsinfo -server ted:7100 xset +fp tcp/ted:7100 xset fp rehash xset q ssh -Y ted On Thu, Oct 27, 2011 at 4:17 AM, Nigel Wade <nmw@xxxxxxxxxxxx> wrote: > On 26/10/11 18:34, Doll, Margaret Ann wrote: > [ OK ] > > [root@ted fs]# netstat -alnp | grep 7100 >> unix 2 [ ACC ] STREAM LISTENING 10796483 >> 6976/xfs /tmp/.font-unix/fs7100 >> unix 3 [ ] STREAM CONNECTED 10796698 >> 6976/xfs /tmp/.font-unix/fs7100 >> >> > xfs is not listening on a network interface.
