From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461) Description of problem: up2date does not work through an ssh connection with X forwarding on. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Start a remote Xserver. (Used CYGWIN/Xfree86 on windows machine) 2. Connect to linux server using ssh -X user@somelinuxhost.com 3. start up2date Actual Results: You see the up2date root logon message through X, then up2date hangs. Expected Results: up2date should have opened in X. Additional info: up2date works fine if it is run via a telnet session setting a DISPLAY=remoteXserver:0.0; export DISPLAY Also this worked prior to the 2.7.11 release.
This seems to work fine for me. I need more info. after ssh'ing, whats the value of $PATH and $DISPLAY? what happens if you su to root and run "up2date"? what happens if you su to root and run "/usr/sbin/up2date"?
After ssh is connected; DISPLAY=localhost:10.0 PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bi n:/root/bin:/root/bin When you su to root it just hangs. Obviously you don't see the X window requesting root logon. I tried a different connection method,using Tera Term Pro with the SSH plugin and WinAxe 6.2 as the Xserver. When I run up2date using this method I get a X fowarding error. TTSSH 'Remote X application sent incorrect authentication data. Its X session is being cancelled.'
reassinging to usermode, since that seems to be causing the problems
Nope, this looks like the ssh X forwarding problem, usermode is not likely to be a culprit here. Closing this for now. Please file a new bug against some recent release if the problem persists.
