  52. ACCEPT all -- anywhere anywhere
  53. ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
  54. REJECT all -- anywhere anywhere reject-with icmp-host-prohibited

  56. Chain FORWARD (policy ACCEPT)

  58. REJECT all -- anywhere anywhere reject-with icmp-host-prohibited

  60. Chain OUTPUT (policy ACCEPT)
  61. target prot opt source destination
  62. [root@localhost Desktop]# iptables -F

本以为这样就可以了，但是ping其他机器 的时候不通。ping 本机通。
折腾了几个小时，找来了其他几个DBA，最后得出的结果是，Dell机器的网卡顺序不一致。
坑！
