I wasn't talking just about connecting to localhost:22, but connections to
localhost with random ports.

Urgh, yeah. It checks whether the connection comes from 127.0.0.1. If your
"localhost" entry does not map to that, connections WILL fail.

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.

IIRC, there's something broken with that, but I don't remember the
details.
Might be related to Bug 510.

  Web search seems to imply this is a known issue with GNOME3

  2) works partially with the KDE desktop. There is the kscreen
  issue that is mentioned in the FAQ.  Really unusable unless
  one does disable kscreen.  Need to investigate further what
  consequences that has on normal logins.

  3) installed MATE from EPEL.  On first login it looks and works great

  terminate the session with x2goterminate-session to clear it out

 So my question is really about the MATE issue which I would prefer to use.
 Anyone have any clues as to what might be going on or a fix?


I'm not sure if it's Mate or X2Go but when I first installed both X2Go 
and

Mate on CentOS7 and tested, all was good.

Now it's broken for me also but somewhat differently.  When I logout it
just hangs with the background image that I used on my desktop.  So I use
control-alt-M to and then click on the white seal or whatever that animal is,
and then when I get the start-up screen back, I select terminate to terminate
the session.

Now I tried the same thing on Scientific Linux 7, which like Centos7 is
derived from Enterprise Linux 7, and it still works correctly, so whatever is

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.

Re: [X2Go-User] Problem connecting to Centos 7 (x2go 4.0.1.19).

2015-08-05 Thread Will Smith
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.

X2Go makes extensive use of SSH tunnels. I suspect your firewall is too strict
and denies access from localhost to localhost. Please make sure that locally,
all connections are allowed.

Hi,

I could select shutdown or restart if I logged off in a xfce4 or kde  
session (maybee additional in other DEs).

I reconize, that formerly the only choise was loggoff in former x2go sessions.

Is this an x2go setting?

[X2Go-User] Problem connecting to Centos 7 (x2go 4.0.1.19).

2015-08-05 Thread Will Smith

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.

 

Many thanks,

 

 

Will.
