Bug - PVE Cluster: VNC error on node

[Pavel Olenev]

Hi!


I have some problem when using vnc console on Proxmox VE 2.1. My cluster contains four proxmox ve servers. When I trying to open vnc console from GUI on master server to virtual machine on node (10.0.0.30) I get this error:

TASK ERROR: command '/bin/nc -l -p 5900 -w 10 -c '/usr/bin/ssh -T -o BatchMode=yes -c blowfish-cbc 10.0.0.30 /usr/sbin/qm vncproxy 133 2>/dev/null'' failed: exit code 255


This error I get with any vm on current node. All other node work fine.
If I open GUI from this node (10.0.0.30) - vnc console work fine too.

I think that I have the same issue, ... the message that I am getting is:

TASK ERROR: command '/bin/nc -l -p 5900 -w 10 -c '/usr/sbin/qm vncproxy 100 2>/dev/null'' failed: exit code 1

I think there needs to be a VNC server installed and configured to support that connection, ... or if that is already in place maybe a firewall rule is preventing it ... any ideas anyone?

I am also seeing this exact same error when trying to access the console from the GUI. I know this worked the last time I used it which was a few days ago. I know my java was just updated on my PC. I wonder if that has anything to do with it.

Did you try this?

I also had the error "exit code 1" some time ago.

@adamb: If you are running Windows (XP), the Java update should have kept you previous version, and you can revert back to it, can you please check and let me know which version it was?
I think I have Java(TM) 6 Update 31 on mine, right now where I am getting the error.

Yes, this could be the solution, that's also written in the link I posted and it solved the problem for me. But Pavel has "exit code 255", don't know if this matters!

Yep this did it for me. Java was disabled.

OK, I got it to work, too, with Firefox 12 and Java (TM) 6 update 31, I guess I was trying this with Chrome, and that one seems to be the reason for the errors.

I have this problem only on one current node on cluster. I.e node 1 is master. If I open GUI from node 1 - I can access VNC to vm on nodes 1,2,4,5,6 etc. But have error on node 3 only. If I open gui from node 3 - I can access to vnc console on this node. All nodes is updated. I think if problem was in firefox/chrome/java - it will be problem with all nodes, not only with current one. And in our network this problem in all computers, not only mine.
