I verified the ssl connection to the local host with:
openssl s_client -connect localhost:443
Then I tried many versions of the check_http incantation, to no avail:
/usr/lib/nagios/plugins/check_http -S -H localhost -p 443
CRITICAL - Cannot retrieve server certificate.
/usr/lib/nagios/plugins/check_http -S -H localhost -p 443
CRITICAL - Cannot retrieve server certificate.
/usr/lib/nagios/plugins/check_http -S -H localhost -u https://localhost -p 443
CRITICAL - Cannot retrieve server certificate.
/usr/lib/nagios/plugins/check_http -S -H localhost -u https://localhost
CRITICAL - Cannot retrieve server certificate.
Is there anything else I could be doing wrong?
On this client, I have installed the following debian 3.1 packages:
nagios-common 2:1.3-cvs. 2:1.3-cvs.
nagios-nrpe-plugin 2.0-7 2.0-7
nagios-nrpe-server 2.0-7 2.0-7
nagios-plugins 1.4-6 1.4-6
nagios-text 2:1.3-cvs. 2:1.3-cvs.
