• -P
  • Sets an optional value for an TLS protocol. e.g xmpp.
  • Automatically gets set for some known port numbers.
• -w
  • Sets the value for the days before warning. Default is 30
• -c
  • Sets the value for the days before critical. Default is 5
• -l
  • Sets an optional label for the host in messages. Default uses /etc/services.
• -h

Example

./check_ssl.sh -H adfinis-sygroup.ch -p 443 -w 40
