年纪大了 记不住命令了 常用LINUX备忘录
1. netstat
netstat -tulnp
-t tcp
-u udp
-l listen 仅侦听，而非活动已建立的连接
-n 按编号而非名称显示主机和端口
-p 显示端口号的本地进程
-p, --program
Show the PID and name of the program to which each socket belongs.
-l, --listening
Show only listening sockets. (These are omitted by default.)
--numeric , -n
Show numerical addresses instead of trying to determine symbolic host, port or user names.

2. tcpdump 抓包
tcpdump -i eth1 -s 0 -w httptest.pcap host 10.180.139.198 tcpdump -i eth1 -s 0 -w testplat.pcap host 10.180.184.41 tcpdump -i eth1 -s 0 -w arpdebug.pcap tcpdump -i eth2 -s 0 -w reg0704.pcap host 10.180.134.26
3. find
[root@jenkins ~]# find / -name HTMLTestRunner.py /opt/rh/python27/root/usr/lib/python2.7/site-packages/HTMLTestRunner.py /usr/lib/python2.6/site-packages/HTMLTestRunner.py
