Hi all,
I routinely connect to remote machines using this command: "ssh -Y
remoteHost". This allows a graphical program to run remotely but
display locally. I've been using this on my laptop fc4 to connect to my
workstation fc4. Everything stays on the workstation. No problem.
I recently installed fc6 on two different machines with similar hardware
capabilities. One is running the stock 2.6.18-1.2798.fc6xen kernel,
and the other vanilla 2.6.18.2. They seem to behave similarly except
for the "ssh -Y remoteHost", where they behave _very_ differently.
Remote programs still run there and display here _except_ firefox and
thunderbird. This is where it becomes very strange.
If firefox is running locally and I try to run firefox remotely I get
two different results. Vanilla kernel causes 70 seconds of network
traffic and finally stops with firefox running nowhere. Remote "ps"
shows it doing a remote ping and trying to launch but eventually dies a
quiet death. On stock kernel it very quickly launches another copy of
the local firefox.
If firefox is not running locally the vanilla kernel still tries for 70
seconds and aborts without logging or complaining, but the stock kernel
will run firefox remotely and display here as expected. If firefox is
running remotely but displaying locally and I try to launch a local copy
of firefox it runs another copy remotely and displays that one here, too.
On to thunderbird. Vanilla kernel will eventuall launch remotely and
display locally, but so slowly as to be unuseable (think 110 baud
modems), displaying, disappearing, reappearing, requesting
configuration, then blowing it away. After about a half hour of it
still not coming up all the way I gave up. On the stock kernel it works
beautifully.
I haven't got a clue how to troubleshoot this. Since everything else
seems to work properly it points to firefox and thunderbird. I don't
know if it is kernel related. The fact that nothing is logged on either
end at any time doesn't help, nor does the diversity of results.
Note that I'm using both fc6 boxes successfully, one as a workstation
and one as a server. It is only using firefox or thunderbird *remotely*
that things go crazy.
Any insights from anybody? Should this be bugzilla'd (or should I be)?
Thanks,
Mike Wright
Mike -
Sorry for the delay in answering, but are you logged in to both systems
with the same username?
What happens if you log in to one system as, say, "mike," but the other
system as "mwright?"
Also, what happens when you do ssh -X instead of -Y?
Thanks,
Thomas
