Hi

I've got a linux RH7.3 system acting as gateway for windows 2000 clients on NAT network 192.168.0.x

I've got a dialup working on the linux box with ppp web browsing, dns resolution etc all working.

on the client machines they correctly getting DHCP'ed all their information including a DNS server address of the 192.168.0.1 machine.

client machines can ping internet hosts.

client machines cannot resolve internet (or local) hostnames.  

whats up with my DNS config?

doh!  i didn't have a DNS server running on the host

one thing tho'  i'm prepared to give the points to someone that can tell me why i can't telnet into port 42 and see the DNS server response.   it just says refused.

cheers

does you firewall (ipchains, iptables) or inetd (/etc/hosts.{allow,deny}) allow the connection?

bendecko,

Port 42?  I though named (or DNS server) should be listening on port 53/TCP.  What is the error message?  connection refused? or connect failed?
