#!/bin/bash

mkdir /tmp/tcpdump
export TcpDump=tcpdump
export SliPackeLen=0
export SliptCapPacket=50000

for ((iLoop=0; iLoop<1000; iLoop++))
do
    ip a |grep bond0 &>/dev/null
    if [ $? -eq 0 ]
    then
    $TcpDump -i bond0 -s $SliPackeLen -c $SliptCapPacket -w /tmp/tcpdump/all_$iLoop.dmp  "(conditions)"and not icmp
    else
    $TcpDump -i eth0 -s $SliPackeLen -c $SliptCapPacket -w /tmp/tcpdump/all_$iLoop.dmp  "(conditions)" and not icmp
    fi
#{ 
#find /tmp/tcpdump -name '*dmp' -mtime +1 -delete 
#}&
done
echo ""

注：
抓包长度使用 -s 参数指定为0 不限制长度，否则会展示时引起kafka truncate 错误
