Comments on VNC Server Installation on CentOS 6.5

It works, thanks. However, I faced 2 small issues on centOS6.5. Firstly, had to add iptables rule to allow vnc port. Secondly, had to set the password for the vnc user. The password is needed because, the screen gets locked after a while and if no password is set then all unlock attempts fails

Had to do this and restart the vncservice

sudo iptables -I INPUT 5 -m state --state NEW -m tcp -p tcp -m multiport --dports 5901:5903,6001:6003 -j ACCEPT
sudo service iptables save
sudo service iptables restart

It's great tool and easy to manage all things of linux GUI.

Thanks,

Prakash

Something changed for CentOS 6.6 because I can't get this work. I tried bondo's iptables command and that returned an "unknown protocol '-m' specified."

Anyone have suggestions?

On Remmina client for ubuntu the VNC configuration requires the user ID not the port.

server: [ip]:1    or      server: [server1.example.com]:1

Hi. Can you help?CentOS 6.7 / firewall disabled

/etc/sysconfig/vncservers# VNCSERVERS="5901:admin"# VNCSERVERARGS[5091]="-geometry 1024x768"

[root@server10 ~]# service vncserver restartShutting down VNC server:                                  [  OK  ]Starting VNC server: no displays configured                [FAILED]

Where I could have done wrong?

You don't need to specify the complete port string. The number you assign to each user will be concatenated to the first three digits of the vnc default ports (i.e. 590 + the_number_you_specify). In your code, the actual port for connection ends up being 5905901, which is, of course, nonsensical. Just remove the 590 and leave the 1 like so: "1:admin"  and VNCSERVERARGS[1] and you should be good to go. 

Srijan,

I want to make the vncserver as service, so it's always running and i can connect to the client even after the reboot. what has to be enabled?

The command:

chkconfig vncserver on

should enable the service to start at boot. If this won't help, then add the command:

service vncserver start

in the file /etc/rc.local

Why do you say, "Please don't install the Development Tools." Is there a conflict? I need the development tools.

Hi,

I have a VPS with CentOS 6 and I installed VNc server to connect to it. Everything works fine, network and internet are ok. But after I reboot the VPS, I can connect the VPS through VNC again but the VPS does not have internet, the network icon showing "red X" with the message "device not managed".I have tried to rebuild the VPS, install VNC and the internet problem comes again after reboot.

This worked for me on CentOS 6.8 nicely. Thanks for the good tutorial.

In my case "yum groupinstall Desktop" failed because such groupinstall was not found at centos 5 with epel and remi repo.
