I am having a problem with SSH X11 forwarding on Fedora 20 with firewall-config
, the GUI tool for FirewallD (the dynamic firewall system). With most X11 GUI applications including pretty much all "system-config-*" programs, I am able to tunnel X11 windows just fine when calling SSH with "ssh -X" / "ssh -Y". However, when I run "firewall-config
" from the SSH session, I get a window with no contents in it. The window has the title "Firewall Configuration" and the correct icon, but the whole content of the window is grey. It also hangs in such a way that I can't close the window or end the program with CTRL-C; I seem to have to do CTRL-Z and then a kill %
command.
Is this a bug in the program? Is it possible that only certain programs using X11 are incompatible with forwarding? Will I be restricted to only using the command-line tool over SSH?
Sorry but calling
xhost +
before the command doesn't solve the problem. – user553702 – 2014-01-11T10:40:00.197@user553702 Then please, after it freezes, do dmesg | tail -n 20 and post the output here, if you can see something concerning this incident. – MariusMatutiae – 2014-01-11T11:15:46.070
