    Legacy Cipher DES: Zabbix 7.0.11 + RHEL 9.5

    Hello everyone, recently I performed a migration from a server (RHEL 8.5) running Zabbix 6 LTS to a new server (RHEL 9.5) running Zabbix 7 LTS.
    In a nutshell the steps were:
    • install Zabbix 6 on the new RHEL 9.5 OK
    • export Zabbix DB from old server and import into new OK
    • on the new server, upgrade Zabbix to v7 OK

    The problem is that some of the monitored hosts only have the DES option and RHEL 9.5 by default isn't recommending it anymore.
    However still hope, on the openssl.cnf file, there're two lines commented clearly referring to DES Ciphers legacy stuff... uncomment...
    legacy = legacy_sec

    [legacy_sect]
    activate = 1


    Zabbix server already reloaded and still not working.
    I'm missing something for sure, after uncommenting how can I be sure that zabbix is now following these new configurations?
    Anyone passed through this?

    Thank you in advance.
Working...
