In case system-config-firewall is started from the menu -> System -> Administration -> Firewall. The program system-config-firewall runs under the normal user "sluser", which has no permission to change the firewall config. That's why you get the error "IOError: Permission denied: /etc/sysconfig/iptables.old" It should work, if you run the firewall configuration as root from the command line: su - system-config-firewall This all happens because I do not set a root password and give all rights to the sluser via /etc/sudoers sluser ALL=(ALL) NOPASSWD: ALL This seems to "confuse" system-config-firewall when starting as normal user. I have to think about how to solve this problem ... any suggestions are welcome. Cheers, Urs
