vnc viewer error: unable connect to socket: Connection refused (111)

Question

I installed tigervnc-server package in server.

[root@localhost ~]# rpm -qa tigervnc-server
tigervnc-server-1.1.0-5.el6.i686

Created a vnc user and created vncpasswd also for that user.

[root@localhost ~]# useradd vnc
[root@localhost ~]# vncpasswd vnc
Password:
Verify:
[root@localhost ~]#

In /etc/sysconfig/vncserver I changed these 2 lines

VNCSERVERS="2:vnc"
VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"

After that I restarted the vncserver service

[root@localhost ~]# service vncserver restart
Shutting down VNC server: 2:vnc                            [  OK  ]
Starting VNC server: 2:vnc 
New 'localhost.localdomain:2 (vnc)' desktop is localhost.localdomain:2

Starting applications specified in /home/vnc/.vnc/xstartup
Log file is /home/vnc/.vnc/localhost.localdomain:2.log

                                                           [  OK  ]

Cleared iptables also.

[root@localhost ~]# iptables -F

While running vncviewer in client side I am getting this error

[root@client ~]# vncviewer 10.10.2.39:2

How to solve this error?

Also you might want to try this option:

-localhost no

The command that works for me is:

vncserver -localhost no -geometry 800x600 -depth 24

The idea is to have vncserver listen on the network interface, rather than just the loopback interface (lo).

Your server is only listening on the loopback address localhost.localdomain:2. Try launching it with the server's IP address specified explicitly:

vncserver -interface [address]

Great... I just changed this line `VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"` to this `VNCSERVERARGS[2]="-geometry 800x600"` now it's working fine. – max Mar 12 '13 at 13:25

Try shutting down the server with this command "vncserver -kill :1" then start the viewer again, no need to reboot.

In my case, this command works for me: vncserver -interface [address] -localhost no
