severe dns config problems

fresh install of mandrake 9.2 on a dell dimension l1000r. the cdrom was kinda b0rking on me so i decided to do a floppy install. i kept getting an error about the ftp servers i was putting in telling me 'bad hostname' .. so i decided to get the ip addresses of the servers and used them instead for the install, which worked. (i had tried this on both ethernet cards in the machine before using the ips)

so i get it all installed (all options except dns, firewall/router, and mail) i think. so i boot it up and on boot the ethernet device fails. i didn't bother to look at why, i just decided to reinstall cause i could let it run while i was at work. this time i used a different source ftp just to be safe and used the other eth card for the install. same problem, fails.

ifconfig shows me the device, but it doesn't have an address, so i give it one. so far so good. adding a default gateway allowed me to ping any host on my network and also on the internet. but trying to ping any hostname would just give me an 'unknown host'

in /etc/resolv.conf my nameservers were already in there, i tried commenting out 'nameserver' since i wasn't running dns, and next i also tried commenting out 'search local' both to no avail.

so i can still ping any host on the internet, and what's more is that when i do an nslookup, it goes right to my dns servers listed in /etc/resolv.conf and i can resolve whatever i want.... aaaaahhhhh

do any of you gurus have any clue on what's going on? i'm at a huge loss, any help would be greatly appreciated.

and while we are on similar topics it seems, and since i was originally trying to use dhcp, i tried adding the

check_link_down() {
return 1;

mentioned in the recent posts, which didn't help out on this one.

ok, looking around in the other threads i found the one about dhcpd, which i had tried but is not installed on my machine...

i did not know about dhclient, which does work to give me a dhcp lease...
i don't know why this is such a huge problem that was never fixed cause it seems to be happening to a lot of people....


MY BIGGEST PROBLEM, still remains... why can i lookup hostnames from dns servers, ping dns servers (and any host for that matter), but yet not be able to ping hosts by their name

this makes no sense to me.
