Couldn't resolve your hostname or Found your hostname (cache

Hi people!!!

Actually, in my UnrealIRCd Server I have 2 servers: (serv1 and serv2). And in my zone there are two predominant ISP: telefonica & auna.

In Serv1:

- When a Telefonica user connect, works: Found your hostname (cached)
- When a AUNA user connect, works: Found your hostname (cached)

In Serv2:
- AUNA & Telefonica users connect, don't work nobody... :
Couldn't resolve your hostname; using your IP instead

In two servers (unix/linux) I make a nslookup to this IP's client and resolve correctly...

Can somebody help me? Very very thanks!!!

!

Well my first guess would be the server's set::dns block is setup wrong. Most likely the timeout is too low. This would cause the server to not receive a reply in time and so even though the IP does resolve, it takes too long for the IRCd to receive it so it just ignores it.

Probably the easiest way to check this is to compare the set::dns blocks of both servers and see if there are differences.

Thanks for your reply, codemastr...

I put set::dns correctly but don't resolve IP.

I put since 6seg to 50seg of timeout, and nothing... don't work...
I put several dns nameserver but unreal don't resolve ...

Is curious, that, with nslookup command the unix don't delay neither 3 seg and resolve IP correctly....

More help? thanks!!
