Dear all,

I assume that due to security reasons such command does not exist "by default" in custom installations but...

Is there any command to query a DNS-server for all the hostnames being served by it? Of course, I could nmap to discover which machines are up and running, but I look for something similar to 'ypcat hosts' ...

Martin,

Make sure you have bindutil installed and look at the man pages for the programs it provides. I'm pretty sure there is something that will do that. Please let us know what you find.

Wow. Can't believe I forgot about dig. Thanks Steve. dig should get you want you're looking for Martin...

If the authoritative servers don't allow zone transfers you're still not going to be able to get the hosts with dig. Greg

THis is as it should be, assuming the "operative" word here actually MEANS "secure" THo, I would think the administrator or other clever sort of people, could , if they actually can physically get to the box, put some sort of redirect to a specific box. or appalience , as long as no one other than they knew . Problem w/ poking a little hole in a secure setup is, folks dont seem able to keep quiet about suchlike things, soon people you dont want to see your various bits of info are looking over your shoulder, no?
