"JH" == Johnny Hughes <mailing-lists at hughesjr.com> JH> It is a feature ... really, it is (according to RH) :). JH> Here is a quote from the RH mailing list: RHML> I think by default X11Forwading is now disabled in RHML> SSH. You can either use 'ssh -X' or change it in your RHML> /etc/ssh/ssh_config. I have the following in mine: RHML> ForwardX11 yes RHML> ForwardX11Trusted yes JH> That should make it work the way you expect. Cool, cool, cool. This problem burned me a week or so ago. I figured out the ForwardX11 change, but I was too busy with the end of the semester to look into it any more than that, so never had a clue about ForwardX11Trusted. Luckily, the problem didn't seem to affect my Mac, so I've been using that as my main system. Until the start of this week, when I started having the same problems with X on my Mac after upgrading to Tiger, which was a pretty big clue, but I still wasn't sure exactly where the problem was. Johnny probably should have stressed that you need to add the ForwardX11 and ForwardX11Trusted keys on your client machine (the machine your X server is running on). Knowing about the -Y flag is also a Good Thing. Thanks!
