Hello the list, I have just compiled a new kernel on my debian box, but I got this messages when I try to load iptables: /lib/modules/2.4.20-9custom/kernel/net/ipv4/netfilter/ip_tables.o: unresolved symbol nf_unregister_sockopt /lib/modules/2.4.20-9custom/kernel/net/ipv4/netfilter/ip_tables.o: unresolved symbol nf_register_sockopt /lib/modules/2.4.20-9custom/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.20-9custom/kernel/net/ipv4/netfilter/ip_tables.o failed /lib/modules/2.4.20-9custom/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables failed iptables v1.2.8: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. Any idea? Regrads Fred
