各位大虾看看下面的错误信息是什么原因造成的？
[root@support /]# iptables -L
/lib/modules/2.4.20-8/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/2.4.20-8/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.20-8/kernel/net/ipv4/netfilter/ip_tables.o failed
/lib/modules/2.4.20-8/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
