problem with ipchains...
I am running Redhat 7.2 linux, and had installed pmfirewall. it worked fine until fewdays back.
now the ipchains giveing an error saying :
[root@server sbin]# ./ipchains -L
ipchains: Incompatible with this kernel
what happend to the ipchains ?
then I tried with this
[root@server sbin]# ./modprobe ipchains
/lib/modules/2.4.7-10/kernel/net/ipv4/netfilter/ipchains.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/2.4.7-10/kernel/net/ipv4/netfilter/ipchains.o: insmod /lib/modules/2.4.7-10/kernel/net/ipv4/netfilter/ipchains.o failed
/lib/modules/2.4.7-10/kernel/net/ipv4/netfilter/ipchains.o: insmod ipchains failed
what could be happend?
and how do I solve this? if I go for iptables, then which firewall easy to configure? something similer to pmfirewall.
