I have been testing both nsyslog and syslog-ng recently (after discovering syslog-ng is based on nsyslog). One thing I have noticed while testing syslog-ng 1.4.4, is that it doesn't appear to allow filters such as: filter myfilter { facility(auth); host(system); }; which were valid in nsyslog. In addition, nsyslog appeared to support reverse lookups of the source ip, to resolve into fqdn. So a message received by nsyslog from host "blah1" would appear in logs as "blah1.mydomain.com". Whereas in syslog-ng it would appear as "blah1" OR with the long_hostnames(yes) option, would log the hostname as "blah1/blah1". Questions: 1. Is it possible to specify multiple criteria per filter? 2. Is it possible to enable reverse lookups and log hostname in fqdn? Cheers, Nick -- GPG/PGP key available on request.
