今天做了一下Squid透明代理.RHAS版本.出现如下情况:
当我运行如下命令时:
/sbin/iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128

说明:eth1是内网网卡.
出现了:
/lib/modules/2.4.9-e.3/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
/lib/modules/2.4.9-e.3/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.9-e.3/kernel/net/ipv4/netfilter/ip_tables.o failed
/lib/modules/2.4.9-e.3/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables failed
iptables v1.2.4: can't initialize iptables table `nat': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
好像是需更新内核或IPTABLES.但以前做没有出现这种情况!!!不明白是怎么回事!!!!
