Setting chains to policy ACCEPT: security raw nat mangle fi[FAILED]

linode的 vps iptables启动报错

之前他们提供的解决方法如下：
cd /etc/init.d
mv iptables ~/iptables.bak
wget http://epoxie.net/12023.txt && cat 12023.txt | tr -d '\r' > iptables
chmod +x iptables
rm -rf 12023.txt

Now, "iptables" should now start successfully:

service iptables restart

现在 http://epoxie.net/12023.txt 这个已经404了各位有何解决办法么？

谢谢
