zabbix-agent 3.4.7 for RHEL 5 without TLS support

[AndreasHH]

When I wanted to configure PSK (pre-shared key) on RHEL 5 with zabbix-Agent rpm 3.4.7 (zabbix-agent-3.4.7-1.el5.x86_64.rpm) I got the following error message.

zabbix_agentd [2836]: "TLSAccept" configuration parameter cannot be used: Zabbix agent was compiled without TLS support
zabbix_agentd [2836]: "TLSPSKIdentity" configuration parameter cannot be used: Zabbix agent was compiled without TLS support
zabbix_agentd [2836]: "TLSPSKFile" configuration parameter cannot be used: Zabbix agent was compiled without TLS support

Is it on purpose that TLS support has been disabled on RHEL 5 / CentOS 5?

In order to use the encryption function, it is necessary to prepare a library for encryption.

ex.
- GnuTLS 3.1.18 or later
- OpenSSL 1.0.1 or later.

Manual:

https://www.zabbix.com/documentation/3.4/manual/encryption

In the RHEL 5 standard package, the versions of those libraries are too old and can not be used.

I think you need to prepare a new library and compile it again using it.
However, other libraries are also old, so that method may not work as well.

Hello Atsushi,

Thanks for the Information. This sounds like some effort to use encryption for zabbix-agent on RHEL 5.
