: 안녕하세요.  Redhat 7.2 kernel 2.4.18 쓰고 있는데요.

Redhat 7.2 는 ipchains 를 쓰지요.

: /lib/modules/2.4.18-17.7.x/kernel/net/ipv4/netfilter/ip_tables.o: init_module: Device or resource busy
: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
:       You may find more information in syslog or the output from dmesg
: /lib/modules/2.4.18-17.7.x/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.18-17.7.x/kernel/net/ipv4/ne
: tfilter/ip_tables.o failed /lib/modules/2.4.18-17.7.x/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables failed
: iptables v1.2.5: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
: Perhaps iptables or your kernel needs to be upgraded.

: 이런 오류만 뜨네요.
