I have a server that I screwed up iptables on. Now when the server restarts it locks up trying to apply the firewall rules.
How can I remove the rules (set to all ACCEPT) in a linux rescue mode or knoppix or other way of getting to the file system?
Any suggestions how to fix this?
Those rules are stored in /etc/sysconfig/iptables, so you have some choices:
1) Boot into rescue mode, then do /sbin/service iptables stop, then exit to boot the system normally. You'll have no firewall at this point. Create the rules as you want them (with iptables command), then do an /sbin/service iptables save to fix the file.
2) Boot into rescue mode, then edit /etc/sysconfig/iptables to make the firewall what you wanted in the first place, then exit to boot normally.
