Code – ssh serverhostname -o ‘BatchMode=yes’ -o ‘ConnectionAttempts=1’ true
Every time a ssh attempt fails, it rights a string “Failed” to the /var/log/secure.
Maybe you can just count that number, and if it goes above a threshold you can alert. Obviously you will need some more logic to check for the day to get your full requirement.
*** this is bash code ***
[root@jralph-linux jralph]# cat check_ssh.sh
#!/bin/bash
COUNT=$(tr -s ' ' '\n' < /var/log/secure | grep -c 'Failed') if [ $COUNT -ge "1" ] then echo "Failed SSH $COUNT" echo "We have some ssh failures" else echo "Things seem to be ok" fi
[root@jralph-linux jralph]# ./check_ssh.sh
Failed SSH 2
We have some ssh failures

echo "$returnCode"
if [ $returnCode != 0 ]
then
echo "Configuration is not valid"
