Multiple scenarios for Shell monitoring Web services

1. Ports

Local: Ss.netstat,lsof

Remote: TELNET,NMAP.NC

2. Number of local processes

3.header (Http,curl), simulating the user's way

4.URL (Wget,curl). How to impersonate a user

5.php,java Write the monitoring program, simulate the user's way (Let development provide)

Sample Judging conditions

[[email protected] ~]# lsof -i :80|wc -l     #本地端口    2[[email protected] ~]# nmap 127.0.0.1 -p 80    # Remote Port starting nmap 5.51  ( http://nmap.org )  at 2017-06-28 14:13  cstnmap scan report for localhost  (127.0.0.1) host is up  (0.000080s  latency). port   state service80/tcp open  httpnmap done: 1 ip  address  (1 host up)  scanned in 0.05 seconds[[email protected] ~]#  nmap 127.0.0.1 -p 80|wc -l8[[email protected] ~]# nmap 127.0.0.1  -p 80|grep open|wc -l  1[[email protected] ~]# ps -ef|grep  nginx |wc -l     #进程12 [[Email protected] ~]# culr -i  -s -w  " %{http_code} " -o /dev/null 127.0.0.1200       #curl [[email  Protected] ~]# wget --spider --timeout=10 --tries=2 127.0.0.1 &>/dev /null[[email protected] ~]# echo $?      #wget看返回值0

Case Shell
