    Hi,

    I have read on some places that if I want to modify supported ciphers I have to use "AllowedCiphers" and/or "EnabledCiphers" options
    https://wiki.netxms.org/wiki/Server_Configuration_Variables
    https://media.readthedocs.org/pdf/netxms-admin/latest/netxms-admin.pdf

    I want to enable only AES256, so I set AllowedCiphers on 1, then restart NetXMS Server and I get a warning "NetXMS Server doesnt support encryption".
    I have netxms server 2.08 running on windows server 2012r2, my version doesn't has EnabledCiphers option, so I create the variable and set it on 1.
    But I get same mesage. If I set AllowedCiphers to 17, it works.
    Do I'm doing something wrong?

    Best Regards

      Hi,

      most likely that's because your JVM does not support AES-256, only AES-128. You may need to download and install "JCE Unlimited Strength Jurisdiction Policy Files" into your JVM.

      Best regards,
      Victor
