Does anyone know of a way to test whether or not X can make it between points A and B? I'm working on a program from a remote box A, and I have MI/X at box B. issuing the following command gives: ==== [root@nic-31 .vnc]# xclock -d 144.15.8.165:0.0& [1] 1263 [root@nic-31 .vnc]# Error: Can't open display: [1]+ Exit 1 xclock -d 144.15.8.165:0.0 [root@nic-31 .vnc]# ==== also, doing ==== [root@nic-31 .vnc]# export DISPLAY=144.15.8.165:0.0 [root@nic-31-c29-111 .vnc]# xclock& [1] 1267 [root@nic-31-c29-111 .vnc]# _X11TransSocketINETConnect: Can't connect: errno = 1 13 Error: Can't open display: 144.15.8.165:0.0 [1]+ Exit 1 xclock ==== both methods give errors, so I'm assuming that either 1) I've messed something up. -or- 2) The firewall I'm behind currently won't let X through Either is quite possible.. Is there a way to assure that 2 is the cause? Thanks in advance, Brian |
