Which machine have you upgraded? The ssh client or ssh server? What happens if you run ssh -Y remote and try to run X11 application again? I did a clean install on the client. I've tested with a number of different servers, RHEL3, RHEL2.1, RHEL4, Solaris 9, Solaris 8, SGI. My home directory is mounted NFS, so my config files haven't changed, and I haven't changed the /etc/ssh/ssh_config. -Y does work. More information. I did an install of RHEL4 on another desktop, and it does not exhibit this problem. The one difference between these is that the one that does not work is dual-headed running Xinerama. If -Y does work then it's duplicate of bug 138875 and more generally bug 137685. It should get fixed by the next OpenSSH update - this adds the ForwardX11Trusted yes to the ssh_config file. |
