Good morning to you all I need your help I´ve installed syslog-ng and it´s cacti plugin and it´s working fine, except for it´s name resolution. For some reason it resolves some names, and doesn´t resolve others. I´m able to ping my hosts by their names without any problem, and I´ve set use_dns(yes) in syslog-ng.conf I´ve done nslookup, and everything´s as it should. Does anybody have any idea why syslog-ng is resolving only some of my hosts names? Any help is very apreciated. Thkx I apreciate any help Thkx ________________________________________________________________________________ Cartão Citi: receba GRÁTIS uma máquina de café Peça aqui o seu http://www.iol.pt/correio/rodape.php?dst=0805131

Which version of syslog-ng?

When you say "it resolves some names", do you mean "it resolves some IP addresses to names"? Can you post an example of a 'destination' where you are using the name?
I´ve done nslookup, and everything´s as it should.
So if you nslookup the IP of each source, the nameserver returns an appropriate name?

What OS? What is in /etc/resolv.conf? /etc/hosts? What is in /etc/nsswitch.conf (or the equivalent for your OS)? I had all sorts of trouble because of slow nameservers (out of my control), I ended up just putting an entry in /etc/hosts for each remote syslog source. Not a scalable solution, but effective. Kevin
I figured out the problem. It wasn´t a problem in syslog-ng, but in my dns server. For some reason I had to re-create my hosts in my foward lookup zone and then reload my dns server. After that, syslog-ng started resolving the names ok.
