grr, DHCP

Hi!

I have a router downstairs that all the computers in the house connect to, and I use Comcast cable.
Using Redhat 6.2 under Gnome, I went to the Network Configurator from the Control Panel, and am having trouble setting up the network connection for that computer.

I've looked around but haven't found things to fit my problem, or get it through my newb self.

When I try to go to www,google,com in Netscape, two errors come up.
The first says

Quote:

Netscape is unable to locate the server www,google,com.
Please check the server name and try again.

The second error has this:

Quote:

"Warning: the following hosts are unknown:
home.netscape.com
home6.netscape.com
internic.net

This means that some or all hosts will be unreachable.
Perhaps there is a problem with your name server? If your site must use a non-root name server, you will need to set the $SOCKS_NS environment variable to point at the appropiate name server. It may (or may not) be necessary to set this variable, or the SOCKS host preference, to the IP address of the host in question rather than its name.

Consult your system adminstrator.

Alright.. I don't know what most of this stuff means..

To make a long post longer =/
Under Routing in the Network Configurator, I set up the default gateway as 192.168.0.1 and the default gateway device eth0.
Interface: eth0, network address: 68.50.15.13, netmask: 255.255.255.0, gateway: 192.168.0.1
For "names", I put hostname: cj241911-a and the domain dlcty1.va.home.com

I got most of the numbers from either telnetting the router on this WinXP computer, or the LAN control panel on XP.

Thank you!

1. Can you ping your router? ping 192.168.0.1
2. Can you ping a server on the internet, such as google? ping www.google.com
3. Paste the output of ifconfig eth0 (do this as root)

1. connect: Network is unreachable
2. ping: unknown host www.google.com
3. eth0: error fetching interface information: Device not found

btw, just ifconfig gives me lo information, and eth0 IS activated

err so.. you can't ping your router.. which means that it is either dropping packets or you haven't been assigned an IP.

Try the following (I'm assuming that you've set the router up on dhcp)

Code:

# ifconfig eth0 up
# dhclient eth0

Then try 3 (from above), then 1&2

well, for me, it looks like your local IP/Netmask doesn't fit your gateway's one,
try setting your local ip to 192.168.0.<SomethingNotUsedInYourNet> with
> ifconfig eth0 192.168.0.xxx up

OR, if you are _sure_ that your dhcp server is working, execute

> dhclient eth0

and check the output of
> dhclient --status (or -s, don't remember...) after executing

(on debian, the dhcpclient is called pump, (pump -i eth0/pump -s) maybe this also works with you)

and try to ping again:
> ping 192.168.0.1

could you send your output from
> ifconfig
