Hi,

Yes, you are right, if you don't set theĀ so_rcvbuf or set it to 0, that means that the syslog-ng will use the kernels default value

Best Regards,

Greetings,

Just looking for confirmation about the so_rcvbuf parameter for the
udp() source driver.

The default is 0. Does that mean that syslog-ng uses the default value
from the kernel?

ie.

cat /proc/sys/net/core/rmem_default
124928

If that is true, then perhaps the syslog-ng admin docs could mention
that. I've scanned "man 7 socket" and don't seen anything that
suggests that a value of 0 for so_rcvbuf means that the socket will
inherit the value.

Thanks for the help!
