Ethernet Config in Ubuntu 5.04

[bern12345]

Linux newbie here!

Here's the specs:

1. A computer (laptop) - Win XP installed.
2. B computer (desktop) - Win XP and Ubuntu 5.04 installed (dual boot)
3. Both computers are on a router.
4. YahooDSL connection.
5. Dynamic IP

When both computers are running Win XP, both can surf the internet without problems.

When I boot the B computer to run Ubuntu, I can't surf or go online with B computer.
Had checked eth0, says it is configured.

What should I do?

Need help! Had been working on it for already two days so I took the courage to place a question in this forum.

type "ifconfig eth0 up" to get ethernet going.

if u use dhcp-client type "dhclient" after eth0 up

If you are still having troubles please paste the output of ifconfig -a.

If you are still having troubles please paste the output of ifconfig -a.

Still having troubles!
Here's the output of ifconfig -a:

I really do not know what to do. Took me days before I can configure how to copy and paste in linux, transfer to a floppy and open it up in windows so i can paste the result in this forum.

Perhaps I got the wrong info for my specs that is why I don't get help from here:

I am very new to Linux and want to try this OS

My problem is I can't get online with Linux.

1. SBC DSL connection, SpeedStream 5100 Modem
2. I have 4 computers ( 2 laptops, one Win95, one with WinXP Pro), one desktop with XP Pro/SUSE dual boot, one Mac.
3. All these 4 computers are connected to a router (CompUSA Cable/DSL router with 4 port switch) and the router is connected to the DSL modem.
4. Booting with windows I do not have a problem connecting to the Internet.
5. The problem is when I boot with SUSE, no internet connection with SUSE only. (NIC is VIA VT6102 (Rhine II) Embedded Ethernet Controller on VT8235) configured on DHCP.

typed ifconfig -a in Yast and here's what showed up.

I know I am doing something wrong here. Can anybody help?
I am very new to Linux and I am so interested to learn this OS.

What are the results of

ping 4.2.2.2

and

ping google.com

from a command line.

What are the results of

ping 4.2.2.2

and

ping google.com

from a command line.

I would personally suggest

ping -c 3 google.com

Go into the kernel and give yourself support for your card and use a dhcp client like dhcpcd.

EDIT: Your card should already be detected. If not then it is unsupported. If it has been dectected then just issue the command "dhcpcd" as root.

[bern12345]

My card is detected.

Here are the results of the following:

ping 4.2.2.2:

64 bytes from 4.2.2.2 icmp_seq=197 tt1=247 time=51.2 ms

and just goes on endlessly...

ping google.com:

ping: unknown host google.com

ping -c 3 google.com:

/sbin/modify_resolvconf:line 245: /etc/init.d/lwresd:No such file or directory

Do these thing help?

[George Harrison]

hmm.. well if the card is detected and you are receiving ping then there shouldn't be a problem..

As root run "dhcpcd".

EDIT: oh wait, you aren't receiving ping. Google was an unknown host. Run dhcpcd and check your /etc/resolv.conf file.

[bern12345]

I got it connected, only if I connect my linux machine directly to my modem.

Do you think it is the router that's not good?

Coz my other machines won't have any connections.
