Hey guys. Before anyone asks, yes, I searched the forums for my problem. I found a few seemingly relevant threads, but none of them worked out for me.

MythTV installed fine. Unfortunately, mythfilldatabase can't connect to the datadirect server. I get the error message:

Failed: Host not found.

I tried apt-get to update the xmltv program, but was unable to connect to anything with that either.

When I try to ping anything outside of my local network, it just hangs.

However, there is SOME connectivity. Myth Weather and News work perfectly.

I'm behind a generic CompUSA router. Cable connection through Time Warner. I'm thinking the problem might be along those lines somewhere, but have zero previous experience troubleshooting networks, and zero experience with Linux. Network card is onboard. Not sure what brand the motherboard is, off the top of my head. I think it uses the NForce chipset.

System specs:

Barebones base system - AOpen XCube Mini ITX system - EA65
256 MB generic RAM
Celeron 2 GHz
ALBATRON MX440 8X AGP Nvidia video card (using Svideo out)

I'm using the onboard sound (though I haven't gotten around to checking that yet, need to get a picture feed first), and I'm using the onboard network card. Being a mini ITX system, I don't have a spare slot to plug in another network card, so I hope I can get this to work. Otherwise, I just blew a load of cash;)

Oh, and my tuner card is some generic card that came bundled with the XCube.

I should probably add that I'm using Road Runner cable for my internet connection. I've read that there were some problems with Road Runner in the past (special login requirements and such), but that they fixed these issues. Not sure if there are still any problems that I don't know about though.

If anyone else out there is using Road Runner without incident, I'd like to hear. Thanks in advance for all your help.

Are you doing your pings to a hostname or an IP address? That will help narrow it down between DNS and actual network connection.

I don't know the "debian" for this command, but nslookup is used on some systems to see what your current nameserver is set to, and to use it to interactively look up names. I haven't used debian enough to know the proper command here...

I tried pinging both hostnames and a few known ip addresses, both to no effect.

Edit: Whoops. Foot in mouth. I just looked up the ip address for google.com (an obviously known good ip address). I pinged it and it worked. Either I mistyped the numbers when I tried the previous addresses, or they were down at the time (I used the ip address for my webserver in Georgia, it was the only numbers I had handy at the time).

Wow. For the first time in days, I feel like I'm making headway.

Okay, I'll update you guys on my results thus far. I edited my /etc/resolv.conf file to point to the correct DNS (it was previously pointing to my router). Everything seems to be working fine... until I reboot. When I reboot, the resolv.conf file gets written over to the old ip address. I don't want to have to edit the file every time I reboot to get my DNS resolved. Ugh.

I'll pound my head against google a bit more, trying to figure out how to get around this, or to stop DHCP from writing over my resolv.conf file. If any of y'all have suggestions, it'd sure make my life easier.

Making great progress thus far though.

Check your DHCP server and make sure it has the correct DNS addresses. I'll bet it is forwarding its own address as DNS when setting up clients.

I think I see what you're saying here, but where do I check for this? KnoppMyth set up the DHCP server automatically, I don't really know where to find it. I've poked around in a few places, but it's all Greek to me.

knoppmyth does not setup a dhcp server it sets up a dhcp client.

you have to look in your router for the dhcp server.

gotcha. Thanks. I'll check my router documentation.
