Dear all,

Does any one success to connect CentOS7 via xdmcp?
I’ve tried, but not yet succeeded.

1) CentOS7 with Development and Creative workstation
2) Disabled SELinux by editing /etc/selinux/config
3) Disabled firewalld by systemctl disable firewalld
4) Enabled xdmcp by editing /etc/gdm/custom.conf
Adding “Enable=true” in [xdmcp] section
5) reboot
7) connect from windows7 PC with Xming-6.9.0.31
“One window” mode with xdmcp connection
-> This is not working.

How I can do next step?

Additional information, I can open single Xterm window through Xming “Multiple windows” mode, but I can’t open gnome-terminal with same way.

I guessed this means thomething wrong in gnome or gdm working witn remote X or xdmcp. But I have no idea to resolve it.

Best regards, Kosuke Yagi

  • I can’t help with xdmcp, but if you are connecting from something capable of running the x2go client (linux/windows/mac) you can use that instead ([packages in EPEL). It doesn’t work with the stock gnome3 desktop due to the 3d requirements, but KDE or the MATE desktop from EPEL work fine. (MATE is a fork of gnome2 and has a very familiar feeling…).

    X2go has the advantage of being able to disconnect/reconnect sessions and will have better performance than native remote X on networks with latency.
