[syslog-ng] if no host; do use_dns

[Lance Laursen]

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?

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.

Thanks,
