Description of problem:
after upgrading openssh to openssh-server-2.9p2-9.i386.rpm, X forwarding
no longer functions properly. I had to uninstall and reinstall openssh-
server-2.9p2-5.i386.rpm to use X forwarding
Version-Release number of selected component (if applicable):openssh-
Steps to Reproduce:
2.open any x application.: bash>xeyes&
Actual Results: invalid mit magic cookie
Expected Results: seamless xforward through secure tunnel
When you log in on the server, what are the XAUTHORITY and DISPLAY environment
variables set to? What output do you get if you run ssh with the "-v" option
when logging in?
ssh X11 forwarding works for me ok. I'd say this bug is a transient issue
of some sort or local config problem.
By default on new openssh in sshd_config X11UseLocalhost set to yes.
So, then app want connect - it try connect to $hostname (usually to real
ip on ethernet/etc...), but sshd bind to localhost:7xxx port.
