[syslog-ng] Enable TLS encryption

[Peter Eckel]

Hi Sathish, 

you want to pass UDP traffic through TLS? That doesn't work out of the box. TLS implies TCP.

TLS encryption for UDP isn't possible. AFAIK Syslog NG does not support DTLS, but you'd need clients that support it as well anyway on the other end, and that's highly unlikely.

You can set up a Syslog NG gateway near the UDP-only logging clients that forwards the messages sent over UDP via TCP/TLS, however. Whether that makes sense depends on your use case. 

Best regards, 

  Peter.
