eth0 works, dhcp does not. help? [SOLVED]

jessicavampirehunter

I have a strange network problem...when I boot up, I see the message

Starting eth0
Bringing up eth0
dhcp
Running dhcpcd [!!]

And then I have no network connection.

I've been searching the forums for a while, trying to see if there's a solution, but most people seem to have problems with eth0, and it seems to me that my problem is with dhcpcd (which I emerged, obviously).

The results of ifconfig

The results of lspci (the network stuff):

Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

I think my driver is 8139too...the one everyone's been having a problem with.

Baselayout is up-to-date.

The results of lsmod | grep 8139too
8139too 18128 0
mii 2800 1 8139too

net-setup is not found.

My /etc/conf.d/net:
config_eth0=( "dhcp" )
iface_eth0="dhcp"

Um, I think that's everything most people wanted to know...I have wireless, but I haven't even begun to configure it yet. I'm just trying to get my Ethernet working. Please help?

Thank you for your response!

OK, I tried that, and no dice. It doesn't seem to have changed anything.

Ok - restart the card and see if you notice anything in your /var/log/messages. You can tail it since it'll be close to the end of the log. If you see anything dhcpcd or eth0 related, please post it up.

Good name for the laptop! Hindu or Final Fantasy buff?

Anyway, dumb questions - have you re-emerged dhcpcd? Is this an onboard card or a pcmcia card?

jessicavampirehunter,

I suspect that your logical device eth0 is not what you think it is. Rather eth1 is your real ethernet port.
Do you have firewire ?
Did you use genkernel?
Does lsmod show eth1394 loaded?

Do you have two real cat5 ethernet interfaces?
If so they have probably swapped logical names between your liveCD install and your own kernel.
Plug your cat5 into the other ethernet port.

neddyseagoon,
Are you thinking that it's picking up the wireless card as eth0 and the hardwire port as eth1? That would definitely make sense, as now that I look back at his ifconfig output, it's saying eth1 is link encap Ethernet.

I re-emerged dhcpcd, and the problem is still there. /var/log/messages still shows the same error as before.

I don't know how to tell what type of card I have...it came with my laptop. How do I find that out?

I have a firewire port...not sure if it needs to be configured or not, though.
I did indeed use genkernel, recompiled to include 8139too since it apparently didn't before.
lsmod | grep eth1394 shows:

eth1394 14872 0
ieee1394 58776 3 eth1394,sbp2,ohci1394

I have just one cat5 port, and one cable...I suppose it's possible that my wireless is registering as eth0, though. I didn't emerge any of the stuff necessary for wireless support - I wanted to get my wired up first.

I changed my /etc/conf.d/net to:
config_eth0=( "dhcp" )
iface_eth0="dhcp"

config_eth1=( "dhcp" )
iface_eth1="dhcp"

hoping that this would configure everything to work, but it didn't. Same error as before..."Running dhcpcd...[!!]"

(incidentally, I'm not a he.

)

HA! I figured out what was wrong. I think.

I think the problem was what you said - that eth0 is my wireless connection and eth1 is my wired connection. So I created an initscript for eth1, with

jessicavampirehunter,

Did I say your were a he? Sorry.

I'm sure that your problem is that the eth0 logical name is being grabbed by the eth1394 module because it loades before your real ethernet port.

You have two ways forward. Make the modules load in the right order. Tolerate the loss of control amd make eth1 work. You will hate that because at your next kernel update, the names may swap again. Since you have started down the make eth1 work, lets finish it off.

It doesn't work for you at the moment because there in no script in /etc/init.d/ to start eth1.
If you look in /etc/init.d/ now you will find a file called net.eth0 which is a symbolic link to net.lo
We need on just like that for eth1 called net.eth1 make it like this
