Hello Venkat,

 I do not know any current issue with IPv4 / IPv6 support. Since IPV6 can support embedded IPV4 it is possible that you have to "constrict" the binding in cases like this. (i.e.: ip-protocol option) Can you please share with us your configuration and the list of your network interfaces (with the configured addresses)?

Note: Starting syslog-ng with the

  -F (foreground)

  -d (debug)

  -e (stderr)

  -v (verbose)

options, syslog-ng will provide verbosed information. Possibly with some details or error messages about the network binding.

Br,

Laci

Hi,

Issue:

when configured both IPV4 and IPV6 syslog server IP's, I could see syslog-ng messages going to only one syslog server, either IPV4 or IPV6 syslog-ng server and that too to the latest server IP configured only.

Is there any known issue ? 

Please help me on this.

Thanks & Regards,

Venkat.
