Ran netconfig and nuked my dial-up

I installed Slack9 and setup a dial-up using pppsetup and kppp only, (no /etc/ppp file editing). Dial-up was working ok. I was preparing to setup my eth0 to smb into a win2k box, so I ran netconfig. I was using autodns to access my ISP's nameserver. Now I can't open any webpages etc due to my nameserver/routing being broken. How do I fix this? I've tried re-running netconfig and using "loopback" to no avail. I even retrieved the DNS addresses from my ISP and tried entering them manually in KPPP and pppsetup, but that doesn't work either. Please explain what I did, how I fix it and if possible a link to a good how-to on setting up an external dial-up and internal network. I've read most of the how-to's on this subject but I find that the HOW-TO's do not keep pace with the newest tools/kernels/methods.

Ok, I've done some more with this problem. I can log on to ISP with no problem. I obviously have a routing problem. I've edited /etc/resolv.conf with the domain and nameserver addresses of my ISP ( The output of route -n is as follows:

Destination Gateway Genmask Flags Metric Ref Use Iface UH 0 0 0 ppp0 U 0 0 0 lo UG 0 0 0 ppp0

My /etc/ppp/options files contain the following lines

I think my default route is pointing to the wrong interface or is setup up improperly. As I already said logging on and staying connected is no problem. I cannot ping any addresses except my ISP's remote IP address and Gateway. How do I fix this. I've tried setting "route add -net" etc. Can any one help?

Your route looks fine to me. You say you can't ping any addresses except If that's true, you can forget about DNS and /etc/resolv.conf, you've got a deeper problem. Are you running any firewall, such as iptables or ipchains? Do you have a /etc/sysconfig/network-scripts/ifcfg-ppp0, and if so, what does it contain?

I figured it out! I had everything setup ok. My ISP's DNS information listed on their website was outdated. I used dnsquery to verify their dns address from another working linux box.
