<p class="MsoNormal">I’m running Xymon 4.3.12 on CentOS 6.4 and monitoring a number of Apache web servers that each have multiple SSL VirtualHosts.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Xymon appears to be using the openssl s_client utility to check server certificates and since s_client is not SNI compliant, it only picks up the certificate of the first VirtualHost. All other VirtualHosts are reported having the same
certificate.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone know of a workaround (perhaps using curl) to validate SSL certificates and track expiration dates of those certificates?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks much.<o:p></o:p></p>
