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

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
