Nagios Monitoring Login Address

#!/bin/bashiplist=$ (W|awk ' nr!=1&&nr!=2&&/pts/| | /pty/{print $ ") Flag=0for IP in $iplistdo if [$ip = ' 180.168.*.* '] | | echo $ip |grep-q ' 192.168.4. Then:else flag=1 Illegal=${ip} fidoneif [$flag-eq 1];then echo $illegal is illegal exit 1else echo All Loginer is legal exit 0fi
