解决iptables Setting chains to policy ACCEPT: security raw nat[FAILED]filter
在ttlsa迁移到靠谱云以前服务器用的是linode,目前还有一些站点依旧使用linode,算算看,我也是linode的忠实用户。有时候在重启iptables的时候总是会出现iptables: Setting chains to policy ACCEPT: security raw nat[FAILED]filter ,想想没什么影响就放着,但是终究是我终究是个强迫症患者,决定修复他。
错误重现
[root@li254-129 ~]# service iptables restart iptables: Setting chains to policy ACCEPT: security raw nat[FAILED]filter iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] iptables: Applying firewall rules: [ OK ]
错误原因
Linode官方在iptables里加了一个security的规则链,但是centos不支持,既然不支持,我就做点手脚吧。
解决iptables: Setting chains to policy ACCEPT: security raw nat[FAILED]filter
找到如下case段,在raw后面加上security)段,修改后如下。
# vim /etc/init.d/iptables 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 ;; security) $IPTABLES -t filter -P INPUT $policy \ && $IPTABLES -t filter -P OUTPUT $policy \ && $IPTABLES -t filter -P FORWARD $policy \ || let ret+=1 ;;
重启iptables
[root@li254-129 ~]# service iptables restart iptables: Setting chains to policy ACCEPT: security raw nat[ OK ]filter iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] iptables: Applying firewall rules: [ OK ]
呵呵,问题搞定了~
