vnc server on fedora12 or higher

peter_u · 01-20-2011, 07:39 PM

I'm trying to setup vnc on a fedora system. currently I am on a fedora12 with SElinux enabled.
I installed with Yum the tigervnc and configured the service with screen 1 for one user "gy".
When I try to conn3ect to it from a windows XP laptop I get the no connection feedback.
So I installed vnc on some other windows box to try connections and it all worked. So something blocks it on fedora.

I disabled SElinux, but it didn't resolve the issue.

Any thoughts?

Did you install VNC or VNC server? Did you open the port that you are trying on?

Thanks for the quick response.

I installed
yum install -y tigervnc tigervnc-server
then I configured:
echo 'VNCSERVERS="1:gy"' >> /etc/sysconfig/vncservers
echo 'VNCSERVERARGS[1]="-geometry 1280x1024"' >> /etc/sysconfig/vncservers
and set a vncpassword for user "gy".
vncserver is active
I opened port 5901 in the firewall from the system/firewall menu, at least I thought so,
and it didn't work, but then I issued:
/etc/rc.d/init.d/iptables stop
and it worked.

I guess now the only question is how to configure the firewall.

IF I remember correctly you have to stop and restart IPtables before the change takes effect.

I found the solution.
The graphical firewall tool from the system menu did not take the port 5901 which I needed to open,
I had to edit
/etc/sysconfig/iptables

and insert a line
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT

After issuing the command
service iptables restart
I was able to connect via vnc from a windows box.

Thanks lazlow for your help.
