Iptables command failed

[manisha s <cdac_manisha@yahoo.com>]

Hello All,

I m new to this mailing list and I don't know if
somebody have faced such a problem and may have
answerd to this question.

I m using kernel 2.4.22 and iptables rpm 1.2.7a-2.
I compiled a kernel to support the Network filtering
successfully. But when i issued the following command

iptables -A INPUT -s 127.0.0.1 -p icmp -j DROP

i got the following error

/lib/modules/2.4.22/kernel/net/ipv4/netfilter/ip_tables.o:
unresolved symbol nf_register_sockopt_Rsmp_f5985dce

/lib/modules/2.4.22/kernel/net/ipv4/netfilter/ip_tables.o:
unresolved symbol nf_unregister_sockopt_Rsmp_a5c3249c

/lib/modules/2.4.22/kernel/net/ipv4/netfilter/ip_tables.o:
insmod 
/lib/modules/2.4.22/kernel/net/ipv4/netfilter/ip_tables.o
failed

/lib/modules/2.4.22/kernel/net/ipv4/netfilter/ip_tables.o:
insmod ip_tables failed

iptables v1.2.7a: can't initialize iptables table
`filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.


what this error means?do i need to update the iptables
or kernel?

Any help or hint would be appreciated

Thanks in advance
Manisha
