Check https not working

[bostjanc]

Hi.
Need a little help.

When we use Nagios command check_http with http site it works ok:
Command: check_http_pattern
Command line: $USER1$/check_http -I $HOSTADDRESS$ -u $ARG1$ -r $ARG2$

but if we wish to check https://internalsite.com we receive an error:
HTTP CRITICAL: HTTP/1.1 302 Found - pattern not found - 889 bytes in 0.037 second response time

Site also has redirection from http to https if that causes that error?
We have tried also putting in argument 1: http instead of https but still will not work.

please help.
with best regards

Site also has redirection from http to https if that causes that error?

Yes, you may want to follow the redirect by adding the following to the command

Code: Select all

 -f follow

Otherwise, we need to see what you are running from the command line to know what else you could be hitting.

Hi.

Thank you for your reply.

If we run on Nagios server:

cd /usr/local/nagios/libexec/
./check_http -I "192.168.1.41" -u "https://oursite.com/Home/Ping" -r "OK"
HTTP CRITICAL: HTTP/1.1 302 Found - pattern not found - 889 bytes in 0.037 second response time |time=0.037284s;;;0.000000 size=889B;;;0

and if we run command:
./check_http -I "192.168.1.41" -u "https://oursite.com/Home/Ping" -r "OK" -f follow
CRITICAL - Socket timeout after 10 seconds

./check_http -I "192.168.1.41" -u "http://oursite.com/Home/Ping" -r "OK" -f follow
CRITICAL - Socket timeout after 10 seconds

How about

Code: Select all

./check_http -I "192.168.1.41" -H "oursite.com" -u "/Home/Ping" -S -r "OK" -f follow

hi.
thank you for your reply.
If we run that command we receive an error:
check_http: Invalid option - SSL is not available

and if we run:
nmap nagiosSERVER.domain..com -p 443

Starting Nmap 6.40 ( http://nmap.org ) at 2019-11-07 00:15 PST
Nmap scan report for nagiosSERVER.domain.com (192.168.1.13)
Host is up (0.000071s latency).
PORT STATE SERVICE

which openssl
/usr/bin/openssl

Does Nagios server needs SSL enabled if we want to check SSL site (our web server)?

Running nmap to check webserver from nagios:
If we run on nagios:
nmap IP-OF-WEB-SERVER -p 443
