Re: [syslog-ng] if no host; do use_dns

----- Original message -----

Hi list,

With keep_hostname(yes), when the syslog-ng box receives a message which does not have a host field, you end up with the last hop IP as the hostname. Is there already a way to tell sysng to use_dns() when this situation is encountered?

it is exactly the use-dns option that controls this.

I'd like to continue using keep_hostname(yes) for all log messages which do have a hostname included, but in the instance that hostname is not included, have syslog-ng do a reverse dns lookup in order to resolve hostname.

this is the behaviour for use-dns(yes)
