External VNC viewer?

in such a case connect via ssh to the Proxmox VE and then:

Code:
vzctl enter VMID
the host can access all containers without the need of a running network.

Thank you, thank you, thank you!!!

I have been looking for the OpenVZ equivalent of xm vm_name console
I was beginning to think it was not possible.
 
Try to debug with telnet:

# telnet IPADDRESS 5900

to see if the vnc server is answering. Or try to use another port.

Cool thanks. I get

Code:
root@devel:~# telnet 10.33.33.131 5900
Trying 10.33.33.131...
Connected to 10.33.33.131.
Escape character is '^]'.
RFB 003.008

And hangs there, waiting for some stream.

Now to search this string...

I tried and tried and tried yesterday and suddenly it started working. Bugger me if I know why it wasn't, I didn't change anything in the process.

Thanks guys!!

PS I would recommend a tick box option in the web GUI to allow external VNC viewing to a VM in Proxmox. That would be the icing on the cake with this beautiful server software! :D
PSS Hmmm maybe I can look at implementing this myself
 
I added this to my /etc/inetd.conf so that I can always connect to my VMs with an external viewer:
9001 stream tcp nowait root /usr/sbin/qm qm vncproxy 101 SecretPassword
9002 stream tcp nowait root /usr/sbin/qm qm vncproxy 102 SecretPassword
9003 stream tcp nowait root /usr/sbin/qm qm vncproxy 103 SecretPassword
9004 stream tcp nowait root /usr/sbin/qm qm vncproxy 104 SecretPassword
9005 stream tcp nowait root /usr/sbin/qm qm vncproxy 105 SecretPassword
9006 stream tcp nowait root /usr/sbin/qm qm vncproxy 106 SecretPassword
9007 stream tcp nowait root /usr/sbin/qm qm vncproxy 107 SecretPassword
9008 stream tcp nowait root /usr/sbin/qm qm vncproxy 108 SecretPassword

Nice work clipcarl!!! :cool:

Is it right that this only works for KVM and not OpenVZ VM's?

I have OpenVZ VM's on 5901 and 5902 and KVM VM's on 5903 and 5904.

Code:
david@david ~ $
telnet 10.33.33.131 5901
Trying 10.33.33.131...
Connected to 10.33.33.131.

Then.. with
/usr/sbin/qm qm vncproxy 101 SecretPassword
Is it possible to transfer file directly to/from Guest VM 101 with VNC client ( like UltraVNC ) if I disable temporanealy VM 101 Network?

I don´t think that this is possible here but never tried.
 
This works great for KVM guests, but I have not been able to figure out a command line to have vncterm started from inetd. I always get a "connection refused" error. I looked through the x11vnc man page, but from what I can see, vncterm does not support most of the x11vnc options.

vncterm does work from the command line (for a single session).

The simplest thing I tried was:
Code:
5902 stream tcp nowait root /usr/bin/vncterm -inetd -c vzctl enter 102
 
I added this to my /etc/inetd.conf so that I can always connect to my VMs with an external viewer:
9001 stream tcp nowait root /usr/sbin/qm qm vncproxy 101 SecretPassword
9002 stream tcp nowait root /usr/sbin/qm qm vncproxy 102 SecretPassword
9003 stream tcp nowait root /usr/sbin/qm qm vncproxy 103 SecretPassword
9004 stream tcp nowait root /usr/sbin/qm qm vncproxy 104 SecretPassword
9005 stream tcp nowait root /usr/sbin/qm qm vncproxy 105 SecretPassword
9006 stream tcp nowait root /usr/sbin/qm qm vncproxy 106 SecretPassword
9007 stream tcp nowait root /usr/sbin/qm qm vncproxy 107 SecretPassword
9008 stream tcp nowait root /usr/sbin/qm qm vncproxy 108 SecretPassword

This works awesome!!! Of course I changed SecretPassword to something else :)
 
having issues getting this to work for 1.4 and a kvm instance.

In short - I setup a kvm - but cannot attach via external vnc
what is the easiest how-to for us to follow here -

server id is 101

Strange - seems I can do this on the 1.3 and earlier - but 1.4 just cannot get it to work (go figure)

Hi typo3usa,

I tried it today and it worked very well. I did what clipcarl recommended.
I use UltraVNC as a client to connect to all my KVM instances. Are you sure you opend the ports on the router (if you are behind one)? And forward them to the pve ip - not to the kvm internal nic?

kind regards
BitRausch

It goes on 1.4 version...
and you remember to made: sh openbsd-inetd restart

Bye
 
I've come up with the attached script to spawn (and respawn) VNC listeners for OpenVZ containers. The script assumes each one listens on 59XX (for 100-199 of course). Usage notes are included at the top of the script.

Usage:
Start with: nohup vz_vnclisten <VMID> &
Stop with: kill `cat /var/run/vz_vnclisten_<VMID>` (may take a while to stop)
Start on boot by adding to /etc/rc.local:
/usr/local/sbin/vz_vnclisten <VMID> &

Hi there,

I read this thread on and on to connect my external vnc to the proxmox kvm sessions with "chicken vnc" on Mac. It didn't go well since now and i tought i share my solution with you guys, who has MacOSX 10.6.2.

On my Site this steps works:

1. Download wine from the internet and install it -> http://winebottler.kronenberg.org/
2. Download also Thight VNC only the excecutable Edition -> http://www.tightvnc.com/download/1.3.10/tightvnc-1.3.10_x86_viewer.zip
3. Start on your Proxmox VNC Server via SSH following command: nc -l -p 5900 -c "qm vncproxy VMID PASSWORD" -> exp.: nc -l -p 5900 -c "qm vncproxy 101 mypassword"
-> tnx for this solution @dietmar
4. Just execute the vncviewer from your Mac -> type in the box your IP ADRESS:PORT -> exp: 192.168.1.1:5900
5. Enter your password

-> Now id should work on your Mac to ;-)

Just to explain why i used TightVnc with Wine?

- I wasn't able to connect over firefox to the openvnc session -> it always gave me a blank page
- I tryed safari too, it works for the moment but it didn't fit the screen size so its not really nice to work with it
- So if i tested the firefox and Internetexplorer from my Bootcamp Partition Windows 7 it always worked perfectly, also tightVnc worked without any problem
