TLS 1.2 support for Nagios Client when calling AWS SES API

[arista-nagios]

We need to enable TLS1.2 for Nagios Client. How to do that? Current Nagios version : 5.7.4

You should upgrade that to 5.10 or higher to fix any issues. The 5.7 series had alot of bugs in it and should be depreciated.

[arista-nagios]

Upgrade is in the pipeline, we will do it soon.
Is there any other way we can configure SMTP to use TLS1.2 and above.

Could you provide more details of your environment? Linux Distribution and version, as well as the PHP version?

The PHP version can be determined by executing

Code: Select all

php --version

in a shell.

For newer TLS versions you need to be at PHP5.6 or higher. Ideally PHP would be at version 7 or 8.

[arista-nagios]

Linux distro: Centos 7.9
PHP version: 5.4.16
Nagios version: 5.7

Can I directly update PHP to 5.6 instead of upgrading nagios?

[jmichaelson]

You should be able to go to 5.6 for sure. However, please bear in mind that versions of PHP older than 8.1 are no longer supported by the PHP organization. Also, while you can stick with the Nagios XI version you're currently running, newer versions contain numerus bug and security fixes, so I strongly encourage you to upgrade your XI installation as well.
