[RESOLVED] Can tigervnc be be configured to use with a non-ssh tunnel client?

Post by taylorkh » 2011/07/26 22:52:05

I found today that the trusty (but perhaps untrustworthy) vnc-server has been replaced by tigervnc-server. A fork from tightvnc-server as far as I can tell. I installed it on CentOS 6 and tried to connect to it with a "regular" vnc client (vinagre on Ubuntu) and that did not work. I tried a java enabled browser and that did not work. And gvncviewer and that did not work. So then I did some reading and learned that tigervnc is designed to use an ssh tunnel. That is of course a nice feature but is a little overkill for my needs. Home LAN behind 2 layers of hardware firewall.

So then I looked for tigervnc (client) for Ubuntu. No such thing in the repositories.

Then I deleted [b] -nolisten tcp -localhost[/b] from VNCSERVERARGS in /etc/sysconfig/vncservers and restarted tigrevnc-server. Still cannot connect.

My questions are... can I configure tigervnc-server to act like the old, less secure, vnc-server? and if so how? Otherwise can I use a tightvnc client with tigervnc-server? I see a package [b]xtigntvncviewer[/b] available for Ubuntu. I guess I will need to give it a try.

TIA,

Ken

I think you might be barking up the wrong tree! I was intrigued and installed tigervnc-server on my C6 install. So my first step after the install is to edit /etc/sysconfig/vncservers and add lines like this

[code]
VNCSERVERS="2:myusername"
VNCSERVERARGS[2]="-geometry 1024x768"
[/code]

Then I had to run vncpasswd as myusername and create ~/.vnc/passwd and then I could run

[code]
sudo service vncserver start
[/code]

Last step...

[code]
sudo iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 5902 -j ACCEPT
sudo service iptables save
[/code]

Now I can connect from my Centos 5 desktop using a tightvnc client.

Thanks TrevorH,
[code]I think you might be barking up the wrong tree![/code] I have been known to do this. I have also been known to get out my chain saw and just cut the darned tree down :-o

I did basically the same as you did. I did remember to vncpasswd. As for the firewall - for testing purposes I just disabled the firewalls on both machines. I will add the necessary ports once I get the things connected.

Well, upon further investigation I found that I did not really disable the firewall on the CentOS machine. I clicked the red Disable button, it grayed out and the green Enable button lighted. But I did not click Apply. I guess I am too used to Ubuntu. The same functionality in Firestarter allows the firewall to be disabled/enabled without an apply. Only adding/deleting/changing rules must be applied.

And after all that... The "built in" vinagre viewer on Ubuntu works fine with tigervnc on CentOS 6.

Thanks again,

Ken

Resisting the urge to mark this thread [as appropriate], I'll settle on [RESOLVED] . . . both for posterity and on your behalf.
