Hi,

i would just like to share how i got an external VNC viewer to work with the new proxmox VNC 2.0

create your KVM machine, once created get the KVM ID (e.g: 100, 120)
SSH into your proxmox host
nano /etc/pve/local/qemu-server/(THE ID).conf - ( nano /etc/pve/local/qemu-server/100.conf )
at the end of config enter the following...

args: -vnc 0.0.0.0:100

this basically tells the KVM to run a vnc from the IP 0.0.0.0 (all) on port 6000 (5900 + what port you set)

run your container, and connect via external VNC :D

its also possible to setup VNC with a password
you do ' args: -vnc 0.0.0.0:100,password ' instead
then go into the console and run ' set_password vnc YOURPASSWORD '
but the console command has to be run every time you start up the VM because it doesnt remember the password for some reason? :confused:

hope this works for people :D

kindest regards

Simon

Why not simply follow the wiki ? ;)

http://pve.proxmox.com/wiki/Vnc_2.0

it's also possible to use your proxmox root password as password (don't known for others login)
Code: 
[COLOR=#000000][FONT=sans-serif]We have added VeNCrypt PLAIN authentication.[/FONT][/COLOR]
[COLOR=#000000][FONT=sans-serif]using tigervnc :[/FONT][/COLOR]
[COLOR=#000000][FONT=sans-serif]- encryption : none ,authentification: username and password[/FONT][/COLOR]
[COLOR=#000000][FONT=sans-serif]you can log with root@pam - rootpassword. (don't have tried with other logins)[/FONT][/COLOR]
 
I tried using http://pve.proxmox.com/wiki/Vnc_2.0 and it doesnt work properly for me.

I have this line in inetd.conf
10101 stream tcp nowait root /usr/sbin/qm vncproxy 101


and telnetting to that port gives me the same as running this command by hand

root@dkproxmoxve1:/etc# /usr/sbin/qm vncproxy 101
{"QMP": {"version": {"qemu": {"micro": 1, "minor": 7, "major": 1}, "package": ""}, "capabilities": []}}


I had to manually by hand create a .vnc file that it asks for.

root@dkproxmoxve1:/etc# /usr/sbin/qm vncproxy 102
unable to connect to socket '/var/run/qemu-server/102.vnc' - Connection refused at /usr/sbin/qm line 57.


root@dkproxmoxve1:/var/run/qemu-server# ls -la
total 56
drwxr-xr-x 2 root root 880 Mar 2 15:07 .
drwxr-xr-x 20 root root 1100 Mar 2 16:44 ..
-rw------- 1 root root 5 Sep 17 09:39 101.pid
srwx------ 1 root root 0 Sep 17 09:39 101.qmp
lrwxrwxrwx 1 root root 28 Mar 2 15:07 101.vnc -> /var/run/qemu-server/101.qmp
-rw------- 1 root root 5 Sep 17 09:39 102.pid
srwx------ 1 root root 0 Sep 17 09:39 102.qmp


but since 102 is not running there are no .vnc file.

Looks like I am linking the wrong file to the .vnc file. But where else should I get it from?


If I try to use tightvnc viewer it does not connect and says "Unsupported protocol: ERROR: unkno"


running this version
ii pve-manager 3.1-20 amd64 The Proxmox Virtual Environment

ii pve-qemu-kvm 1.7-6 amd64 Full virtualization on x86 hardware

ii pve-cluster 3.0-12 amd64 Cluster Infrastructure for Proxmox Virtual Environment

I want to add this:

root@dkproxmoxve1:/var/run# dpkg -l qemu-server

ii qemu-server 3.1-15 amd64 Qemu Server Tools


My /etc/pve/qemu-server/101.conf file already contains this line

args: -vnc 0.0.0.0:101


maybe that is why?
 
okay, so now TigerVNC fails with authentication failure, but I have supplied both my own account credentials and root credentials, it still will not let me log in. Any idea why?
