linux 使用脚本实现自动Ping多台服务器测试连通性

#!/bin/bash
pingcmd()
{
prefix="SERVER $1 PING $2"
ping -w 1 -c 1 $2>/dev/null
ret=$?
if  [ $ret -eq 0 ]
     then printf "$prefix\t Ok\n"
     else printf "$prefix\t ERROR\n"
fi
return 0
}

echo "--------------------------"
echo "核心网1.1.1  PING FROM 1"
echo "--------------------------"
server0="192.168.0.14"   #本机的IP地址
server1="192.168.0.13"
server2="192.168.0.15"
server3="192.168.0.72"
server4="192.168.0.124"

pingcmd $server0 $server1
pingcmd $server0 $server2
pingcmd $server0 $server3
pingcmd $server0 $server4
