Hi, I have Solaris 8+ systems with a working OpenSSH 3.9p1 build which work perfectly. We set X11Forwarding to yes in the config and get DISPLAY=localhost:10.0 allowing X tunnelling back. I have just recently built OpenSSH 5.2p1 and installed sshd on some machines and now the DISPLAY env variable is not set at all. As far as I can tell, nothing else has changed (account dot files are the same, client ssh is still 3.9p1 and sshd_config is the same). The only way I can get DISPLAY to work is to set X11UseLocalhost to no in sshd_config and then it gets <hostname>:10.0 and works just fine. I have tried forcing X11DisplayOffset and XAuthLocation (and checked that it was right). I have tried ssh -X (though that is the default) and ssh -Y and none of these make any difference. The messages from -vv show the two calls to xauth followed by "Requesting X11 forwarding with authentication spoofing" and "channel 0: request x11-req confirm 0" just the same as the working version. I can only presume that I have done something wrong with the build but can't see what. Any ideas please? -- Cheers, Rick Parsons Bristol, England
