resolving problem (I think)
 

Just giving Fedora Core a whirl, I've set up my dial-up connection using redhat-config-network; no problems there but I'd rather be using wvdial. I've configured wvdial.conf etc, it dials and connects just fine but

returns something like: "host not found/unknown"

This is something to do with DNS isn't it? Anyway, where is the correct file to edit?

Cheers.

if you are using dialup then you should be able to get your DNS address automatically. while dialing check your
log file
#tail -f /var/log/messege

can you ping any public ip without dns??

any way's the correct location for your dns file is
# vi /etc/resolv.conf

nameserver primary-dns-ip
nameserver secondary dns ip
