# 1、 judgeMasterNos.py 先启动,以后台方式启动;
# 2、 judgeMasterNos.py启动以后sleep 2秒后再启动arpProxy.py同时通过ps命令查看arpProxy.py进程是否存在如果不存在将启动失败信息写入到当前目录下的log中
# 3、 arpProxy.py启动以后sleep 2秒后再启动icmpProxy.py同时通过ps命令查看icmpProxy.py进程是否存在如果不存在将启动失败信息写入到当前目录下的log中
# 4、 icmpProxy.py启动以后sleep 2秒后再启动udpProxy.py同时通过ps命令查看udpProxy.py进程是否存在如果不存在将启动失败信息写入到当前目录下的log中
# 5、 udpProxy.py启动以后sleep 2秒后再启动tcpProxy.py同时通过ps命令查看tcpProxy.py进程是否存在如果不存在将启动失败信息写入到当前目录下的log中
# 6、 判断arpProxy.py、icmpProxy.py、udpProxy.py、tcpProxy.py四个进程是否存在如果不存在将错误信息写入到log中。
