Nagios/Icinga Plugin that checks for SSLv2 and SSLv3 support

Uses OpenSSL s_client to perform support checks for SSLv2 and SSLv3 or STARTTLS/SSLv2, SSLv3 on various services.


  • Copy bin/check_poodle into /usr/local/bin/check_poodle and make it executable.
  • Copy services/poodle into /etc/nagios/objects/services (or /etc/icinga/objects/services) and modify the files for your need. They expect a hostgroup named 'all'.
  • Restart Nagios/Icinga.
