I’m trying to set up a VNC server using the instructions at http://www.techrepublic.com/blog/linux-and-open-source/linux-101-easy-vnc-server-setup/
I am up to step 6:
Step 6: Edit iptables
In order for the VNC connections to get through, you must allow them with iptables. To do this, open up the file /etc/sysconfig/iptables and add the line:
-A INPUT -m state –state NEW -m tcp -p tcp -m multiport –dports
5901:5903,6001:6003 -j ACCEPT
Save the file and restart iptables with the command:
service iptables restart
When I issue the restart command I get:
iptables: Applying firewall rules: iptables-restore: line 1 failed
Note that I did not have an iptables file before but there is an iptables-config file.
Can someone help me complete this configuration.
