• 查找包含smb端口

[root@server0 ~]# netstat -antp | grep smb
tcp        0      0 0.0.0.0:445             0.0.0.0:*               LISTEN      3499/smbd

• 查找包含http端口

[root@server0 ~]# netstat -antp | grep http
tcp6       0      0 :::80                   :::*                    LISTEN      7032/httpd        

• 关闭 使用80端口的服务

[root@prxy src]# netstat  -antp  |  grep 80
tcp6       0      0 :::80                   :::*                    LISTEN      5510/(squid-1)      
[root@prxy src]# kill 5510
