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 [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. Thanks! -larry
