Nagios Support Forum

Is it possible that encryption is disabled for the service? Are you able to run:
?

Hello,

The wget is not working from the VMA box, But when I try it from the nagios server it's working, Is there any package that need to update in VMA box for fix this issue ?

What OS is the VMA box running?

I recently ran into an issue with another perl plugin that didn't work on cent6 because the SSL modules were outdated and didn't support SNI. Do you know if SNI is a requirement for the non-working machine? You may need to upgrade perl on the VMA system to get this support.

Hello,

VMA is SUSE Linux Enterprise Server 11 SP3 for VMware (x86_64) - Kernel)

It seems SNI is not enabled for the domain. I have checked using this command from Nagios server openssl s_client -connect serverip:443 and it's showing the SSL details.

Also, I have checked the SSL details of the working and not working domain. Please see the below details.

can you advise if we upgrade Perl or OpenSSL package is it affect current working domains check?
Also kindly provide the package name we need to update if it needs.

I don't see ECDHE-RSA-AES256-GCM-SHA384 on vmabox. You may need to install the openssl 1.0.1g:

Since updating libraries on another machine is a bit beyond our scope, you may want to reach out to the Suse team to assist with this if needed.
