I've just installed TigerVNC on my Fedora 15 machine from the package manager then in terminal (as root):
chkconfig vncserver on service
vncserver start
None gave me errors, so I went back to the Windows 7 machine and fired up the viewer. But after a few seconds i get
unable to connect to socket: connection timed out(10060)
Does anyone know what to open up or fix on the Fedora machine to make this happen?
VNC servers on linux generally run on port 5900+$DISPLAY, wich is in most cases 1, so default vnc port on linux will be 5901 instead of 5900 on windows machines. Firing up the VNC server a 2nd time will launch it on 5902 (since the first display is already in use).
When connecting with a vnc client u will have to specify this port in your viewer: f.e.:
192.168.0.101:5901
Check for firewall on your fedora system by (as su):
iptables -nvL
If the firewall is blocking you should add a rule to accept packets on port 5900.
Check if the port is open on your fedora machine (as su):
netstat -tpln | grep "5900"
If you don't get any output, it means the daemon isn't running or their is some configuration problem.
Also you should use vncpasswd to set a vnc password on your fedora machine.
iptables -A INPUT -p tcp –dport 5900 -j ACCEPT in terminal. However changes will be lost unless you make it execute at startup. Hope that helps.

netstat -tpln led me to the answer to my problem. Followed a tut that said to use :1 when starting the server which results in the server listening on port 9001. My viewer was trying to connect to 9000. Changed it to :0 and it now works.

Could be that the server listening on port 5901. TigerVNC on Centos 6.0 listens on 5901.
iptables -nvL. On Windows, we can't help you.
