Summary: check_http -S fails with some servers

Initial Comment:
Hello Ton and all,

while updating from v 1.4.13 to v. 1.4.14 I observe check_http behaving rather strangely when performing HTTPS checks. Same platform (openSUSE 11.2), both plugin versions were compiled without any deviating configure options:

nagios-plugins-1.4.13> ./plugins/check_http -S -H <host>  -p 8443 
HTTP OK HTTP/1.1 200 OK - 2328 bytes in 0.205 seconds |time=0.205096s;;;0.000000 size=2328B;;;0

nagios-plugins-1.4.14> /plugins/check_http -S -H <host>  -p 8443 
CRITICAL - Cannot make SSL connection 
HTTP CRITICAL - Error on receive

With other servers, however, the same test (same port) succeeds even with version 1.4.14. Any advice on how to proceed?

Best

     Patricia

Hello Thomas,

thanks for taking this up quickly! Yes, both plugin versions I compiled
freshly from scratch yesterday. Unfortunately the host in question is only
accessible via VPN, but I'm happy to help out with tests.

Message:
Thanks for your report. I've seen this bug previously (in debian trackers,
I don't remember if there's a NP trackers counterpart).... So far it seemed
to be a compatibility problem with OpenSSL, and last time I checked I could
not find a single change in nagios-pugins that could explain this.

So the most important question is did you freshly compile both plugins
version at the same time (i.e. with the same OS patches/underlying
libraries)?. Ideally I would like that you start from fresh tarballs in an
empty directory, extract them, configure, compile and test both versions.
If you can still reproduce this regression from fresh builds I will further
investigate.

It would be nice if you could include the full verbose output (-vvv) of
the plugins, the exact version of OpenSSL you're using (i.e. installed OS
packages) and the output of "pkg-config --modversion openssl".

It would be even better if you can also provide an externally accessible
URL I could test with (using private mail if you wish).

Thank you
