    |  centos vpn 接通后无法连接internet | 
    |  | 
    |  | 
    | vpn可以连接到服务器并成功连接,但是无法上任何外网网站。 经查:
 
 1.在vpn client pc上ping 服务器的pptpd地址192.168.80.1,可以ping通,ping服务器的外网地址也可以ping通,ping google或任何internet地址都不能。
 
 2.因此怀疑是服务器没有做ip转发。
 
 上到服务器上,查iptables, (实际上iptables是centos的防火墙,但是也是用来ip转发forward的)。
 用来查转发的命令是 :
 
 iptables -t nat -nL
 
 发现由于多次调试,里面杂乱无章,用下面命令清空:
 
 iptables -F
 iptables -X
 iptables -t nat -F
 iptables -t nat -X
 
 然后重新做:
 
 iptables -t nat -A POSTROUTING -s 192.168.80.0/24 -o seth0 -j MASQUERADE
 
 这个指令完成后立刻生效绝对不要重启iptables, 应为错误的 iptables设置还在/etc/sysconfig/iptables中,一重启反而还是错的。
 
 立刻测试vpn,发现问题解决,的确是转发有问题。
 
 这时把/etc/sysconfig/iptables移走,然后
 
 /sbin/service iptables save
 
 把正确的/etc/sysconfig/iptables文件保留下来,这样重启iptable service才不会依然是错误的。

    |  centos 取消屏保 | 
    |  | 
    |  | 
    | 发现centos 时间一长,就自动黑屏屏保,这样不方便监控,查后只要这样做, 
 setterm -blank 0
 
 并在/etc/rc.d/rc.local 加入这句,就可以在启动后自动把屏保关掉。
