linode无法启动iptables解决办法

 最近买了台linode的vps来代理和缓存,没想到在把iptables规则整好后,居然无法启动iptables,报以下错误:

1.第一个问题解决办法:
   cp /etc/init.d/iptables /etc/init.d/iptables.oldbak--
   vi /etc/init.d/iptables
   查找case "$i" in这行,如下内容:
       for i in $tables; do
        echo -n "$i "
        case "$i" in
            raw)
                $IPTABLES -t raw -P PREROUTING $policy \
                    && $IPTABLES -t raw -P OUTPUT $policy \
                    || let ret+=1
                ;;
            filter)
                $IPTABLES -t filter -P INPUT $policy \
                    && $IPTABLES -t filter -P OUTPUT $policy \
                    && $IPTABLES -t filter -P FORWARD $policy \
                    || let ret+=1
                ;;
            nat)
修改成如下:
    for i in $tables; do
        echo -n "$i "
        case "$i" in
            security)
                $IPTABLES -t filter -P INPUT $policy \
                    && $IPTABLES -t filter -P OUTPUT $policy \
                    && $IPTABLES -t filter -P FORWARD $policy \
                    || let ret+=1
                ;;
            raw)
                $IPTABLES -t raw -P PREROUTING $policy \
                    && $IPTABLES -t raw -P OUTPUT $policy \
                    || let ret+=1
                ;;
            filter)
                $IPTABLES -t filter -P INPUT $policy \
                    && $IPTABLES -t filter -P OUTPUT $policy \
                    && $IPTABLES -t filter -P FORWARD $policy \
                    || let ret+=1
                ;;
            nat)
2.第2个问题解决办法:
cp /etc/sysconfig/iptables-config /etc/sysconfig/iptables-config.oldbak--

关闭ip_conntrack_netbios_ns模块
sed -i 's/IPTABLES_MODULES="ip_conntrack_netbios_ns"/##IPTABLES_MODULES="ip_conntrack_netbios_ns"/g' /etc/sysconfig/iptables-config

3.重启iptables
service iptables restart
Flushing firewall rules:                                   [  OK  ]
Setting chains to policy ACCEPT: security raw nat mangle fi[  OK  ]
Unloading iptables modules:                                [  OK  ]
Applying iptables firewall rules:                          [  OK  ]

好了,iptables启动起来了,问题解决,只能说linode内核加载的模块太少了.
