Perhaps this is more of a firewalld question, but any > further light which can be shed on the issue would be most useful. Maybe your resolver does weird things with firewalld running? In any case, whether firewalld is running or not, localhost should (not just for X2Go, but in general) not resolve to a public IP address. Sadly I have no idea what could be misbehaving, other than the resolver. The hosts file should be prioritized in /etc/nsswitch.conf, but there's probably ways to screw that up.

Robert, I think this is an issue that you should raise over on X2Go-Dev, or file a bug for it. Even if CentOS is at fault, it's more likely to catch the attention of the developers "over there", and reporting it as a bug makes sure it doesn't get lost as time goes on. - -Stefan - -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243 -BEGIN PGP SIGNATURE- Version: GnuPG v2 iQEcBAEBCAAGBQJVwlqCAAoJEG7d9BjNvlEZTvUH/1hT914BEV7IHSiqcDXyAMZ1 oD2RzXzjF567bdXWTxki6pTuHH8JCuJyMbE1UvjvCCO5gXvtVi/lfk/c5FAO5LVV BzJirsnKkp7MV5tEbfbNdSH860XdtHIynvDFwMNHgmLJGTstLA8rrcqQosgPA9dy 6hLLY/RRGz2DDgYBzdo1tF/OoJxw8E/YL6StM6LyUBqkIXvWk2jijN8b7shX9WOY c3fq4QxrgJ84Qcv+7hX80DSb0YrT8SILZwxaDSNNTzCKk1bR8j4N/Qob5Rd/l/R+ 2shgn55p8XXjfUHE4SaQpv7yQbj2LIH1zkWR2+gRZFhNLGwkPtpTgaQDiZbtB2k= =XMkf -END PGP SIGNATURE- ___ x2go-user mailing list x2go-user@lists.x2go.org http://lists.x2go.org/listinfo/x2go-user

First hit when you type "Gnome" in the wiki's search bar is http://wiki.x2go.org/doku.php/doc:de-compat?s[]=gnome And subsection http://wiki.x2go.org/doku.php/doc:de-compat?s[]=gnome#compatibility_and_workarounds_depend_on_what_version explains which versions of Gnome X2Go is compatible with.

Re: [X2Go-User] Problem connecting to Centos 7 (x2go 4.0.1.19).
Dear Mahai, Many thanks for your response. I can ssh localhost from the server no problems. Indeed, all services on localhost are trsuted. Having investigated further, I can see that it uses the public IP address when attempting to bind to localhost rather than 127.0.0.1 when firewalld is running. Cf. with firewalld running, the logs contain Info: Agent running with pid '204654'. Session: Starting session at 'Wed Aug 5 14:57:49 2015'. Info: Proxy running in server mode with pid '204654'. Info: Waiting for connection from 'localhost' on port '30011'. Warning: Refusing connection from '131.***.***.100'. 100' on port '30011', and I'm unable to connect, but after stopping the firewalld service, and reconnecting, they contain Info: Agent running with pid '214487'. Session: Starting session at 'Wed Aug 5 15:19:53 2015'. Info: Proxy running in server mode with pid '214487'. Info: Waiting for connection from 'localhost' on port '30011'. Info: Accepted connection from '127.0.0.1'. Info: Connection with remote proxy completed. and I can connect no problem. The routing table is the same in both cases. My /etc/hosts file contains the localhost line first and the public hostname/IP address line second. Perhaps this is more of a firewalld question, but any further light which can be shed on the issue would be most useful. Many thanks, Will.

I suspect your firewall is too strict and denies access from localhost to localhost. Please make sure that locally, all connections are allowed.

[X2Go-User] Shutdown selectable but gladly not work

[X2Go-User] Problem connecting to Centos 7 (x2go 4.0.1.19).
Dear All, I'm having a stange problem when attemping to connect to my Centos server using x2goclients (Ubuntu & mac, 4.0.5.0). I'm running firewalld, but port 22 is unblocked and I am able to ssh into the machine and forward X traffic. When accessing from both a mac and an ubuntu client the session appears to start, but then immediately disconnects. The client logs say: Info: Proxy running in client mode with pid '12054'. Session: Starting session at 'Wed Aug 5 12:38:47 2015'. Info: Using abstract X11 socket in kernel namespace for accessing DISPLAY=:0. Info: Connecting to remote host 'localhost:31003'. Info: Connection to remote proxy 'localhost:31003' established. Error: The remote NX proxy closed the connection. Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie. Session: Terminating session at 'Wed Aug 5 12:38:53 2015'. Session: Session terminated at 'Wed Aug 5 12:38:53 2015'. If I attempt to reconnect, I can see the session, but am unable to resume it. The strange thing is that if I stop firewalld, I'm able to access the server from both clients with no issues, which implies it's a firewall issue, but as I say port 22 is unblocked and I can forward X traffic. Is there some other obvious firewall setting I've failed do? Any assistance in fixing or diagnosing this issue would be highly appreciated.
