   Thanks,  I just had a look at your link.  We are running slackware-12.1.0 32 bit.  Which is
why I am compiling everything. Not sure if something for centos or fedora will work.

FYI the package over at Terabithia works with TLS 1.2 out of the box.  I have an httpd that is TLS 1.2 only.

Hi Frank,

what happens if you leave out the --ssllib and --sslinclude parameters? It is an unusual location for OpenSSL to be installed, so I guess you compiled it yourself?

It also ought to pull in libdl.so automatically, but that probably requires some magic when compiling OpenSSL.

Anyway, I believe you can work around it by setting NETLIBS in xymon-4.3.27/build/Makefile.Linux like

  NETLIBS="-ldl"


Regards,

Henrik

   Hi everyone,

We are changing all our SSL web sites on windows over to tls1.2. So I have upgraded the
openssl on the xymon server.

     I have run into an ssl issue compiling xymon-4.3.27 and xymon-4.3.28

openssl   is in /usr/share/openssl-1.0.21

 ./configure.server --ssllib /usr/share/openssl-1.0.21/lib --sslinclude /usr/share/openssl-1.0.21/include

This is my error:
