Hi Guys and girls,
I am new to Linux and am determined to make it work, however, this has me stumped. I am sure that it is an easy fix but I don't know which little command to issue.
My installation of Red Hat 7.2 will dial up and connect to my ISP through Kppp easily enough, I can view web pages IF I use the IP address. If I type the host name in, I get DNS type errors (no such host etc.) I have a standard desktop type system with an external modem.
Initially I assumed that it was resolv.conf, so I checked it about 20 times, the DNS servers are correct. I tried nslookup -d2 (to see what was going on) and basically the output said "bad packet". Today it found an address and found the same errors.
:smash:
I have posted the nslookup below.
I don't like to say it, but the addresses that I am using work just fine for Windows. If you have any idea what is going on here I would appreciate the help.
thanks heaps.
Aleks.
