Where to find network config files

[geckolabs]

I was working on my linux box network configuration with netconf. I seem to have everything working but still no network access. I was hoping to look at the network config files via vi,emacs etc. If someone could tell me where to find the files for DNS, GATEWAY, etc that would be great. I am using MD 7.2 and was using netconf thru KDE if that matters.

Thanks

DNS - /etc/resolv.conf
gateway is set by route (just type route to see what it is and use commands like route add default gw [IP address] to add a default gateway)
