Hello Venkat,

 I recommend the following options beside your current ones (note: those are already indicates some advanced level of usage):

 -F run syslog-ng in the foreground (otherwise you only get debug logs if you enable the `internal()` source)
 -d enable the debug logs
 -v increase the verbository level

note: run syslog-ng with the following command: syslog-ng --help-all

Br,
Laci

Hi Laci,
I am not able to enable debugs for syslog-ng.
could you please share the complete command to enable debugs.

we are using the below command to start syslog-ng:
/sbin/syslog-ng -f /etc/syslog-ng/syslog-ng.conf -R /var/syslog-ng.persist -p /var/syslog-ng.pid

Regards,
Venkat.

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.
