In the System It has libipt_connlimit.so file. but don't have ipt_connlimit.ko or .o file. Is this the reason why can't load the connlimit module? If it's the reason , then need I recombile the kernel? I have done so, but When I patch the kernel with the latest patch of POM, and comblie the kernel. errors occured. Just like I have said ----------------------------------------------------------------- CC net/ipv4/netfilter/ipt_connlimit.o net/ipv4/netfilter/ipt_connlimit.c: In function `count_them': net/ipv4/netfilter/ipt_connlimit.c:68: error: structure has no member named `proto' net/ipv4/netfilter/ipt_connlimit.c:94: error: structure has no member named `infos' net/ipv4/netfilter/ipt_connlimit.c:101: error: structure has no member named `infos' make[3]: *** [net/ipv4/netfilter/ipt_connlimit.o] Error 1 make[2]: *** [net/ipv4/netfilter] Error 2 make[1]: *** [net/ipv4] Error 2 make: *** [net] Error 2 ---------------------------------------------------------- I don't know what's wrong with it . version conflict? or GCC version not right? or other reason? I don't know why, can you help me? thanks 2005/10/28, Rob Sterenborg <rob@xxxxxxxxxxxxxxx>: > On Fri, October 28, 2005 08:19, Buddy wu wrote: > > I want to use connlimit to set the connections of each person to a > > certain number, but when I add a rule using iptables, error occured > > like these: > > > > [root@server1 linux]# /sbin/iptables -A INPUT -m connlimit > > --connlimit-above 6 -j DROP > > iptables: No chain/target/match by that name > > > > I have searched for this problem, someone said it maybe need to > > load the ipt_connlimit module.
