Ping script on Linux and Auto-discovery on zabbix3.xx

Sometimes we need to ping some addresses on Linux to determine if the address is occupied

First, write the shell script

The script is as follows:

#!/bin/bashfor i in 192.168.16.     {1..255} do (ping $i-C 2 >/dev/null 2>&1 [$?-eq 0] && echo "$i is Alive" ) &done

The effect is as follows

Second, the use of fping

Fping needs to be installed separately, it can ping a group of addresses,-G to specify a set of addresses, such as

Fping-g 192.168.16.1 192.168.16.200

Represents all the addresses between these two addresses.

-A option indicates that the alive is printed out of the host
[Email protected]:/tmp$fping-a-G 192.168.16.0/24 2>/dev/null
192.168.16.1
192.168.16.2
192.168.16.128
192.168.16.129

-u option to print out the unreachable host
[Email protected]:/tmp$Fping-u-G 192.168.16.0/24 2>/dev/null
192.168.16.3
192.168.16.4
192.168.16.5
...< ...
192.168.16.254

The effect is as follows:

Iii. Use of Nmap

NMAP-SP 192.168.99.0/24

The effect is as follows:

Iv. Automatic discovery using Zabbix

Because the ping host may not be allowed, because there is a terminal server on the firewall on Ping,zabbix can configure the Autodiscover rule, you can find the state of the host through PING,SSH, to determine the host address

Whether it is occupied

The effect is as follows:
