Hello, I am currently log into a work computer (which I do not have easy physical access to) and I log in using "shh -X username@someipaddress". The work computer is running Mac OSX 10.5.*. When I log in, I receive the following error: Warning: untrusted X11 forwarding setup failed: xauth key data not generated Warning: No xauth data; using fake authentication data for X11 forwarding. But the more important problem is that when I try to run "open some.pdf" I get the following error: kCGErrorRangeCheck : Window Server communications from outside of session allowed for root and console user only INIT_Processeses(), could not establish the default connection to the WindowServer.Abort trap I get this error pretty much anytime I actually try opening something to utilizes the GUI via the X forwarding. I'm not sure that these two problems are related, but it is quite annoying. I've googled around and have not found an adequate solution to this. Yes, the file /private/etc/sshd_config has X11Forwarding set to yes. If anyone has any insight that would be much appreciated. Thanks.
