Hey,
There's a nifty little tool called neat (aka system-config-network)
you can use to set up your network settings. I don't use gnome or kde
anymore, so I can't tell you exactly where it would be on your menu, but
you can open up a terminal and type "neat" or "system-config-network" to
open it. It opens up in the "Devices" tab. You should see your network
card listed. Double click it to bring up a dialog to set your IP info
(DHCP if that's what you're using, or if you have a static IP address
you'll enter it manually here). There are 3 tabs in this dialog, but you
only need to worry abuot the first one (general). Click ok once you're
done, then go to the DNS tab on the main window and enter the DNS
servers for your ISP (ipconfig /all in win xp will give you this info if
you don't have it). After that, File->Save then quit the program. It
will say you may need to reboot etc etc, but all you really need to do
(from the terminal again) is run the command:
/etc/init.d/network restart
After that you should be good to go. In case you are interested in
what's going on behind the scenes, I'll tell you what neat is doing. As
you may know just about everything in linux can be configured in a text
file somewhere. Most of the network configuration information lives in:
/etc/sysconfig/network (file containing hostname to use, and toggle
networking on/off)
/etc/sysconfig/network-scripts/ (directory containing per-device
information for each NIC)
Every network card in your system will have a file in
/etc/sysconfig/network-scripts/ called "ifcfg-<devicename>". So in the
case of a single network card (called eth0), the settings are stored and
can be changed in /etc/sysconfig/network-scripts/ifcfg-eth0. Here's an
example of what it looks like:
# Intel Corp.|82540EM Gigabit Ethernet Controller
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:0D:9D:FF:23:5D
IPADDR=172.16.25.53
NETMASK=255.255.0.0
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
PEERDNS=no
GATEWAY=172.16.255.1
IPV6INIT=no
You may notice that DNS information isn't stored here. That's because
it's a system-wide type of thing, not specific to any one network card.
Host resolution and DNS info is stored in a file called
/etc/resolv.conf. You can get more information about that by typing "man
resolv.conf" at the command line, but the basics are you can use the
nameserver directive to list your DNS servers like so:
search cms-stl.com dhcp.cms-stl.com # tells it to try and tack on
cms-stl.com etc to hostnames if it can't find them
nameserver 172.16.1.1 # dns server #1
nameserver 172.16.1.4 # dns server #2
Modifying this file will take effect immediately, nothing needs to be
restarted.
I hope some of this info can help you get online. Welcome to Linux, I
hope you enjoy your adventure!

Hello,
I recently installed Fedora Core 3 on my computer and am not sure how to
configure the system so that it can access the Internet. It recognizes
the ethernet device to which I am plugged in to. I am at a college
campus and plugged directly into an ethernet port in the wall. I copied
down information I thought I might need from XP's ipconfig before going
on to install Fedora (things like what my DNS suffix, IP, subnet mask,
and default gateway were at that time). I am new to Linux and Fedora and
would appreciate any help anyone can offer. Thanks!
