I have a home network which consists of a DSL 'modem' attached to a Linksys router which provides DHCP service to two Windows computers, and a combined router/print server. Works fine.
Recently loaded Fedora C-2 on a third machine, was previously used for Windows, but installed Fedora as the sole OS. Machine has one NIC.
During setup I enabled firewall, with www, FTP, SSH and Mail(SMTP) allowed.
I (think I) set up the network to automaticall obtain a network address using DHCP.
Problem is, I can't fond the network, can't ping the router, etc.
Hardware is recognized, and seems to be working.
I know I'm doing something(s) wrong but what?
I'm using the graphical interface, chosen during setup, because I thought it should be easier (!?) Have not yet figured out how to get to the CLI.
Can one of you kind people point me in the right direction?

Hi Olddog2, welcome to lq. First I'd disable the firewall completely until things are working, then you can enable it and configure on from there. Next we need to see if the nic is up and running, You should have an icon on your desktop that looks like a tv with a seashell on it. That's Konsole, it's give you access to the cli from the gui. Open it, at the prompt issue
su -
rootpassword enter your root password.
You should now be root with root's environment. Please issue the following commands and post the output here in this thread.
lspci -v
lsmod
ifconfig -a
route -n
We'll need all of this info to help. Hopefully we'll get you going.
good luck.
I don't have the TV with seashell icon (konsole) on my desktop, and I couldn't find it anywhere on the Start menu or sub-menus. So I opened up Terminal, and entered su, and it prompted for root pswrd, and accepted it.
lspci -v <response was> bash: lspci: command not found.
I got the same response for:
lsmod <resp> bash: lsmod: command not found
ifconfig -a <ditto>
route -n <ditto>

Im no guru but it looks as if Eth0 is not accepting the dhcp, Also you will need to enter the DNS name severs manually as fedora seems to like this better. Most likly your going to use this server for some testing of network applications so I'd put a static IP on it for easyer finding when you decide to run your webserver,mailserver..... This is what i would do.

I agree you're not getting an ip address. The tricky part will be pinning down why. The hardware seems ok, but just to check try assigning a static address. Some dhcp clients are picky so you might try changing the client.
good luck.
