I did a lot of the KA9Q DNS resolver code, and it certainly does TTL and authority correctly. The very early Karn code didn't, but he integrated my changes years ago. But, NOS doesn't act as a SERVER, which is what I think the requestor wants. For that, Linux or any Unix variant would be a fine choice.

For that, Linux or any Unix variant would be a fine choice. For a Domain Name Service Server, I have used DIS NET.EXE, available from ftp.demon.co.uk. I think that Mark Turner or Giles Todd added the server code. It works exactly like "named", supports multiple zones, can act as primary or secondary, and configuration is very easy. The original poster (whose address I have lost) should take a look at it. Also for ethernet situations, FTP Software sells a DNS server which runs over their kernel. Haven't used it though.

I was not talking about your resolver code. I should have clearer about that. WAS> But, NOS doesn't act as a SERVER, which is what I think WAS> the requestor wants.

None of this code that I know about is very solid, and no one has put much time into it, either. NOS is limited in memory under DOS, and acting as a name server is not a particularly efficient use of it. -- Mike ------------------------------ Date: Wed, 10 Aug 94 21:27:00 -0000 From: mikebw@bilow.bilow.uu.ids.net (Mike Bilow) Subject: DNS To: tcp-group@ucsd.edu On 94 Aug 22 at 22:38, Ashok Aiyar wrote: AA> On Wed, 10 Aug 1994, William Allen Simpson wrote: >> I did a lot of the KA9Q DNS resolver code, and it certainly >> does TTL and authority correctly.

I am not at all familiar with that variant. Where can it be found? AA> The original poster (whose address I have lost) should take AA> a look at it.

The only server implementations I have seen in NOS are far more limited than what you describe. It is not particularly easy to code a name server, and there are numerous subtle traps. Also, many people have come to take for granted what are really optional features, such as recursion. -- Mike ------------------------------ End of TCP-Group Digest V94 #170 ******************************
