What specs does a DNS HAVE to have?

I was just looking for others suggestions. I'm looking to add another DNS to my network. This DNS would server for domain resolution for my webservers. (low traffic servers at this time) I was going to use Centos 4.4 with bind 9. I'm hoping I could use an old HP Celeron 500Mhz with 256 for this. Maybe a 20 or 40gb hard drive. Does aothers think this machine would work sufficiently?

Thanks in Advance.

oh yeah that'll be fine really. i'd suggest slimming things down a lot though. don't run x windows, don't run any other servers etc... as for disk space, you really don't need more than a few gigs dns doesn't use disk space.

Sweet! Thanks for the quick reply. I actually have a 4.2gb drive I can use. Unfortunaly I'm not good yet with the command prompt yet to feel confident enough to configure bind. I'm not sure what the edit tools and such linux has nor to work them yet

I don't think Webmin takes up that much space. I could work well with that. Maybe I can just use that hard drive minium operating system with bind.

Another quick question you might could answer. I have windows DNS servers atm. I will just use this new server as a slave of course. With the windows DNS server I have 2 NIC cards in them so that I have internal net access to the server and then public access. However, after its idle for a bit, I have to disable to internal net card or the server will quit responding to tcp packets and dnsreports errors on those servers. I made sure the dns server setup knows to reply to queries on the public card. Do you know if this is a problem on linux servers?

The non-responsive issue is not something you shouldn't see in linux. Of course, you shouldn't see it in windows either.

A DNS server is a great way to learn the command line. If you're setting up a slave server, there really is nothing to it. You add the domain names to the named.conf file, and give the IPs of the master servers. You can use any text editors for that - the two most popular are vim and emacs, but there are probably hundreds at this point.
