iptables: No chain/target/match by that name problem with linux-2.6.20

Hi ,

I am using Linux -2.6.20 with iptables-1.3.8.

I am getting the iptables error :

“/sbin/iptables -I OUTPUT -p udp -m multiport --sport 23,22,161,80,443,53,49 -m state --state NEW,ESTABLISHED,RELATED -o mgmt0 -j ACCEPT”

iptables: No chain/target/match by that name

I have enabled the connection tracking and iptables in kernel configurations.

The command works in linux -2.6.11 fedora core 4 machine.I compared the two kernels and found out the differences in the ip_conntrack.ko module is missing

In the linux-2.6.20 kernel, instead it has xt_conntrack.ko and nf_conntrack_ipv4.ko modules.

The .config file looks like :

# Core Netfilter Configuration

# CONFIG_NETFILTER_NETLINK is not set

CONFIG_NF_CONNTRACK_ENABLED=m

CONFIG_NF_CONNTRACK_SUPPORT=y

# CONFIG_IP_NF_CONNTRACK_SUPPORT is not set
