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 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 CONFIG_NF_CONNTRACK=m CONFIG_NF_CT_ACCT=y CONFIG_NF_CONNTRACK_MARK=y CONFIG_NF_CONNTRACK_EVENTS=y CONFIG_NF_CT_PROTO_GRE=m CONFIG_NF_CT_PROTO_SCTP=m CONFIG_NF_CONNTRACK_AMANDA=m CONFIG_NF_CONNTRACK_FTP=m CONFIG_NF_CONNTRACK_H323=m CONFIG_NF_CONNTRACK_IRC=m CONFIG_NF_CONNTRACK_NETBIOS_NS=m CONFIG_NF_CONNTRACK_PPTP=m CONFIG_NF_CONNTRACK_SIP=m CONFIG_NF_CONNTRACK_TFTP=m CONFIG_NETFILTER_XTABLES=m CONFIG_NETFILTER_XT_TARGET_CLASSIFY=m # # IP: Netfilter Configuration # CONFIG_NF_CONNTRACK_IPV4=m CONFIG_NF_CONNTRACK_PROC_COMPAT=y # CONFIG_IP_NF_QUEUE is not set CONFIG_IP_NF_IPTABLES=m CONFIG_IP_NF_MATCH_IPRANGE=m CONFIG_IP_NF_MATCH_TOS=m CONFIG_IP_NF_MATCH_RECENT=m CONFIG_IP_NF_MATCH_ECN=m CONFIG_IP_NF_MATCH_AH=m CONFIG_IP_NF_MATCH_TTL=m CONFIG_IP_NF_MATCH_OWNER=m CONFIG_IP_NF_MATCH_ADDRTYPE=m CONFIG_IP_NF_FILTER=m CONFIG_IP_NF_TARGET_REJECT=m CONFIG_IP_NF_TARGET_LOG=m CONFIG_IP_NF_TARGET_ULOG=m CONFIG_IP_NF_TARGET_TCPMSS=m CONFIG_NF_NAT=m CONFIG_NF_NAT_NEEDED=y CONFIG_IP_NF_TARGET_MASQUERADE=m CONFIG_IP_NF_TARGET_REDIRECT=m CONFIG_IP_NF_TARGET_NETMAP=m CONFIG_IP_NF_TARGET_SAME=m With Regards Pranav Jadhav
