Before I carry, please feel free to tell me FAQ off; I have quickly scanned the archive and google and haven't found a solution to this problem - but I'm open to suggestions. I'm initialising iptables on RH Linux 8. When I start iptables I am getting the error message " can't initialize iptables table `' ". Now, I issued `lsmod` and I have both "iptable_filter" and "ip_tables" modules loaded. I initially tried starting ipchains with a whole raft of rules, but even starting with the single rule: -P INPUT DROP causes this error to appear. When I reboot the machine and check my syslog messages, I notice that iptables-restore is issuing a modprobe for module `iptable_`, as in: iptables: Applying iptables firewall rules modprobe: modprobe: Can't locate module iptable_ modprobe: modprobe: Can't locate module iptable_ ... iptables: can't initialize iptables table `' (do you need to insmod?) which leads me to believe that some table module it requires isn't loaded. Is this correct, and if so how is this. I'm only using the default "filter" table (which is loaded) with my single policy rule... Any help or pointers to solutions would be greatly appreciated.
