CheckSSLCertExpiry

This was a good starter script. It works as it should after modification. I ended up modifying it to say... ####################################### #!/bin/bash SitePort=$1 OutDate=$(echo | openssl s_client -connect ${SitePort}:443 2>/dev/null | openssl x509 -noout -endda$ OutputDate=$(date -d "${OutDate}" "+%s") SystemDate=$(date '+%s') DiffTime=$(expr "${OutputDate}" - "${SystemDate}") if [ "${DiffTime}" -ge 864000 ] then echo "Certificate will expire on ${OutDate}" exit 0 elif [ "${DiffTime}" -le 863999 -a -ge 5 ] then echo "Certificate is going to expire in less then 10 days on ( ${OutDate} ). Please Renew!" exit 1 elif [ "${DiffTime}" -le 4 ] then echo "Certificate has EXPIRED on ( ${OutDate} )! Please replace!" exit 2 else echo "ERROR! Certificate NOT found!" exit 2 fi #######################################
