We've run into a problem with ssh X11 forwarding, apparently since the 8/23/2008 yum update of openssh packages.
In the very recent past we were able to 'ssh -X' from an SL 4.6 host to another SL 4.6 system, and from there do an 'ssh -X' to a third SL 4.6 system and have X11 traffic pipe its way back to the original host with no problems. Now, in the last few days, we find that the 'ssh -X' from first host to second works fine, but then an 'ssh -X' to the third results in: Warning: untrusted X11 forwarding setup failed: xauth key data not generated Warning: No xauth data; using fake authentication data for X11 forwarding. And firing up any X11 app on the third host fails with: X11 connection rejected because of wrong authentication. X connection to localhost:12.0 broken (explicit kill or server shutdown). I've started googling for this, but thought I'd throw it out in case others are experiencing the same problem or maybe Troy/Connie have a thought or fix. Thanks! - Larry -- P.
