Hi,
Xymon asks OpenSSL to connect using any available SSL/TLS protocol and this should auto-negotiate to whatever protocol both sides support, which is what SSL/TLS clients (browsers etc) would normally do.
This is different from what you do with the command-line tests below; you explicitly request one of the TLS 1.x methods, so auto-negotiate is turned off. Could you running this command without the "-tls*" option?
Have you tried to configure Xymon to specifically use TLS 1? Put "httpst://www.example.com/" in hosts.cfg (the the 't' added to https). This will specifically request a TLSv1 connection. You are right that Xymon does not have similar ways to request TLSv1.1 and TLSv1.2 connections.
Regards,
Henrik

Hi Henrik,
It is. Specifically I use this:
openssl s_client -connect xymon:443 -tls1 2>/dev/null | grep Renegotiation
Secure Renegotiation IS NOT supported
openssl s_client -connect xymon:443 -tls1_1 2>/dev/null | grep Renegotiation
Secure Renegotiation IS NOT supported
openssl s_client -connect xymon:443 -tls1_2 2>/dev/null | grep Renegotiation
Secure Renegotiation IS supported
This is what xymon logs in xymonnet.log which you can also see alerting for the xymonnet column on the web page:

My guess is, Xymon doesn’t properly support the minor versions of TLS?

Hi David,
Xymon uses the openssl library on the Xymon server to do SSL/TLS. So the most basic of tests would be to run "openssl s_client -connect xymon1.domain.com:443" to see if your OpenSSL library supports the necessary protocols.
Note that you may have multiple versions of OpenSSL installed, so to be 100% sure check the version of OpenSSL that Xymon uses: "xymonnet --version" will tell you which OpenSSL version it was compiled with, and "ldd ~xymon/server/bin/xymonnet" will show you (on Linux, at least) what the actual library is that is used by xymonnet.
Regards,
Henrik

Mark Felder,
Mentioned last year around April 17^th , 2015 where Xymon support
for TLS v1.1 and v1.2 may be lacking. Perhaps the issue is more
my naiveté but does anyone know how I can get the sslcert and http
tests to work correctly with Apache and Xymon.
red https://xymon1.domain.com/ - SSL error
The sslcert test goes purple.
Os: Red Hat Enterprise Linux Server release 7.2 (Maipo)
Openssl: OpenSSL 1.0.1e-fips 11 Feb 2013
Xymon: 4.3.26
