Is anyone else having trouble getting ssh to tunnel X11-forwarding? On MacOS X the following works flawlessly... 1) Enable the Remote Login service (ssh) on remote.foo.bar 2) On local.foo.bar execute... xhost +remote.foo.bar ssh -X -l username remote.foo.bar 3) once logged into remote.foo.bar via ssh execute... setenv DISPLAY local.foo.bar:0.0 With those commands I can run xcalc and glgears between two MacOS X 10.4 boxes but these commands do not appear to work from a Fedora Core 4 or RHEL3 box to either Fedora Core 4 or MacOS X 10.4. Any ideas on what could be going wrong? With linux running xcalc fails with an error of... Error: Can't open display local.foo.bar:0.0 Thanks in advance for any advice. Jack
