Re: [syslog-ng] error='self signed certificate in certificate chain'

13 Mar 2016

      Thanks  Robert.
With required-untrusted,  I am able to communicate with syslog-ng server with TLS encryption.

I want to establish mutual authentication and need required-trusted option

Could you please let me know how to solve the following certificate issue with required-trusted option
Regards,
Girish

Hi,

try setting the peer-verify option to required-untrusted (https://www.balabit.com/sites/default/files/documents/syslog-ng-ose-latest-g...)

HTH,
