[Bug 592434] Re: ssh -X user@machine hangs when using exit to terminate
Try running the remote X client using dbus-run-session(1), which I have on my FreeBSD build of dbus: $ ssh mybox $ dbus-run-session -- gedit I came across this thread looking for why ssh sessions in which I ran /certain/ X clients would hang the session when I tried to exit. Now that I know it's a dbus issue, I came across a dbus session wrapper program that suits my needs perfectly. Now I can alias those naughty commands while in an ssh session. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/592434 Title: ssh -X user@machine hangs when using exit to terminate To manage notifications about this bug go to: https://bugs.launchpad.net/dbus/+bug/592434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 592434] Re: ssh -X user@machine hangs when using exit to terminate
I've given up on it for now.. it requires substancial changes and is a quasi-design flaw with dbus. I am curious (- I haven't checked) what happens with the switch to sdbus/kdbus. Eventually it might be worthwhile to actually have dbus start and manage your ssh session (the server side only of course) and then everything should might work fine, then you can have bash as a systemd managed user job. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/592434 Title: ssh -X user@machine hangs when using exit to terminate To manage notifications about this bug go to: https://bugs.launchpad.net/dbus/+bug/592434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In this is that dbus-launch will connect to the remote X server and scope itself to that, which will cause ssh to refuse to exit because there are still clients. Basically: ssh -X remotehost firefox & Now, scoping of the bus is a long debated mess, but there is a reasonable fix for the ssh -X case; we scope the bus lifetime to the requesting client, not to the X server. This patch adds --exit-after-clients-exit option to the bus, which will cause the bus, after an initial connection is made once, to exit after it has no connections. dbus-launch --autolaunch is modified to use this. Now, in the Firefox case what's actually going on is that it talks to GConf, which was recently modified to scope to DBus, bus since no bus is available it autolaunches one. The resulting gconfd-2 process hangs around after ssh exits, but will eventually time out. Possible regressions: * Previously dbus-launch looked at the X server to try to find a bus address; this worked in the "local" (i.e. same uid-kernel) case where one manually sets: DISPLAY=:0 somedbusapp A specific example of this case is the legacy Unix getty. But I don't see this as a big problem; there are other environment variables, and really, the right fix for this is to have the OS default to single session.

You cannot remove this functionality. Well, eventually my goal is just "some-dbus-command" works (this gets back to OS single session). I agree maintaining DISPLAY= setting for legacy gettys is desirable (I use it myself sometimes), though I don't see such a hard and fast "you cannot remove" rule for random Linux voodoo commands. The question is - can we come up with a variation that "fixes" the ssh case without changing anything else? It looks like recent versions of OpenSSH put "SSH_CONNECTION" in the environment; in that case, we could simply not connect to X. We could also check inside dbus-launch for whether the X is remote, and if so ignore it. However - if it comes down to "do we 'break' getty or do we 'unbreak' ssh", I think the latter really has to win.

This is really a dbus issue, not a SSH issue: see http://serverfault.com/questions/405518/how-to-configure-d-bus-and-ssh-x-forwarding-to-prevent-ssh-from-hanging-on-exit Gedit for whatever reason is looking for an active dbus-session and running `dbus-launch --autostart' if none was found. But `dbus-launch --autostart' doesn't watch the user session and therefore ssh hangs while waiting dbus-launch to quit. A workaround is to run 'dbus-launch --exit-with-session' when you first connect over SSH.
