Redhat 9 and DHCP/DNS issue...please help.

[tel1jag]

Hello,

I was just wondering if anyone had any insight on this issue...

I am running Red Hat 9.0 and have just about everything working, however, I am able to get a DHCP address, but no DNS information is sent down.

I get the ip and routing information...but nothing gets inserted in resolv.conf. I have seen some docs on creating an /etc/dhcpc directory with another resolv.conf file, but that didn't fix anything.

Anyone have any suggestions?

Thank you.

What's the DHCP server? Have you tried to network any other machines via DHCP with the server?

Doesn't matter...I get the same issue with any DHCP server. On my home network it's a Linksys box, at work it's a Microsoft server. If I boot into Windows the DHCP works, if I boot into Linux the DHCP gives me an IP address and routing info, but no DNS info.

What happens when you populate resolv.conf manually?

On RH9, configure your name server via: "System settings, network configurator", then select the DNS tab. I have mine harcoded to my DNS server, even though I don't recall doing that...
Having said that, there are 2 tools in RH9, pump (older) and dhcpcd which does the updating of /etc/resolv.conf behind the scenes... do a "ps as | grep dhcp" and you you will see that dhcpcd starts with -n -H as parameters.
Try killing it and restart it. I've used ethereal to check my packets and I DO get both domain info and DNS info from the DHCP server. Good luck!
