Gentoo not acknowledging Ethernet-Controller, or Dhcp.

metacym · n00b Joined: 04 Apr 2009 Posts: 17 Location: Oregon

Hello. I am a new Gentoo user, but have used Arch for a while.

I installed Gentoo AMD64 2005 from live disc on an old Compaq sr1920NX tower. it has an nVidia-bridged ethernet controller, ( to which the green light is on, which i would assume should mean it is working properly )

I have not been able to get it to acknowledge or start eth0. there is no wireless card as an option. Also, i downloaded the forecdeth driver on my laptop,
But the Gentoo compaq will not recognized the jump drive for me to even pull that off of it. I also typed dmesg, and the jump drive shows up there, but nowhere else.

resolv.conf only displays:

#Generated by dhcpd for interface eth0
nameserver 192.168.2.1

"resolve.conf" [converted] 2L, 64C

192.168.2.1 is the address that my macbook pro is assigned for internet sharing over eth0, so i dont see the problem there.

net-setup as a command says "command not found" and ifconfig only acknowledges loopback interface:

lo Link encap: Local Loopback
inet addr: 127.0.0.1 Mask: 255.0.0.0
inet6 addr: ::1/128 Scope: Host
UP LOOPBACK RUNNING MTU: 16436 Metric:1
RX packets: 0 errors: 0 dropped: 0 overruns: 0 frame: 0
TX packets: 0 errors: 0 dropped: 0 overruns:0 carrier: 0
collisions: 0 txqueuelen: 0
RX bytes: 0 (0 .0 b) TX bytes 0 (0 .0 b)

also, i tried to do: /etc/init.d./net.eth0 start

and i received the error message

Starting eth0
* configuration not set for eth0 - assuming DHCP
* No DHCP client installed.

So, here is where it get's worse. i cant use portage to update anything, because there is no internet connection. I cant transfer files to the gentoo box yet, because i cannot access the jump drives.

yeah, so it seems like i could be close to a solution, but i need some more insight on this.
cheers, - metacym.

"jump drive" - wtf is this ?
what kind of nvidia ethernet card do you have ? maybe provide us some info for example the outpout of

If you can get network to work on a differint distro or a livecd run post the output of lsmod and dmesg from that to determine what drivers are being used.

So i booted the machine in question into a Backtrack3 live disc that i had laying around, and i was unsuccessful at getting ethernet connectivity as well.
I suppose that any more trouble shooting Gentoo at this point is pointless if i cant even discern if this is a hardware issue or not.

the ethernet light appears. the ethernet controller shows up in the lspci | grep ethernet command. I am stumped at this point.

The forcedeth driver has been available in Gentoo since at least 2006 (probably before). I've had one of these running since that time:

update: , ifconfig now acknowledges eth0. unfortunately, i dont know what changed it. it could have been the command i issued earlier to modprobe forcedeth.
unfortunately, even though it sees eth0, it is not providing internet connectivity. Any advice is appreciated.

Link encap: Ethernet HWaddr 00:17:31:F7:7D:7A

All the normal parts that list the packets, errors, droped, overruns and frame all list
"0"

The modprobe created what you're now seeing with ifconfig.

Now try your /etc/init.d/net.eth0 start.

thanks for your help.

/etc/init.d/net.eth0 start prints:

starting eth0

No DHCP client installed.

There are new gentoo sources:

cach0rr0 · Posted: Sun Apr 05, 2009 7:54 am Post subject:

if you can get eth0 up, then you *should* be able to set a static IP if nothing else
you should write down your netmask, broadcast, and default gateway that's known to work on another box for that network
then configure a static IP once you've gotten eth0 recognized
then /etc/init.d/net.eth0 start

that should give you connectivity - then emerge dhcpcd, undo your changes to /etc/conf.d/net, and carry on (assuming you want to use dhcp, start dhcpcd, and add it to your default runlevel)

Still no ethernet.
Okay. so here are my variables:

networks configuration:

loopback 127.0.0.0
link-local 169.254.0.0

# the primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.120 <---- static IP i manually set
netmask 255.255.255.0
network 192.168.1.1
broadcast 192.168.1.255
gateway 192.168.2.1

#dns-* options are implemented by the resolvconf package, if installed.
dns-nameserver 192.168.2.1

here is my resolv.conf

#Generated by dhcpcd for interface eth0
nameserver 192.168.2.1
nameserver 192.168.1.1

/etc/init.d/net.eth0 start prints:

* Starting eth0
*configuration not set for eth0 - assuming DHCP
*No DHCP client installed.

/etc/conf.d/net is blank, and says that if left blank, DHCP will be the default, However i dont know what to put there instead of the blank, dhcp default.

You are using wronf config file format. The one you had used is taken from Ubuntu Linux, it will not be recognized by Gentoo, that is why you see

metacym · n00b Joined: 04 Apr 2009 Posts: 17 Location: Oregon

thanks for your reply.

I re-did everything per the guide you linked to, and the same DHCP error persists.

* i should add that i re-did the config for static-IP per the guide you linked me to .

So i have made a sliver of progress.

After re-configuring conf.d/net, I once again issued the command /etc/init.d/net.eth0 start, and this time it printed:

* Cachine service dependencies...
* Starting eth0
* Bringing up eth0
* 192.168.1.120
* network interface eth0 does not exist
* please verify hardware or kernel module ( driver )
localhost init.d #

So being a n00b, How do i go about verifying hardware or kernel module? I had thought this is what i did when i did "modprobe forcedeth"

Update:

eth0 is now up and running, but still not facilitating internet.

ifconfig prints:

i also re-did "modprobe forcedeth" , and "ln -s net.lo net.eth0" , and "rc-update add net.eth0 start", as well as set "kernel-version 2.6" in modules.autoload.d.

Everything seems so close to working, i just still am not sure what to do next.

after reboot, ifconfig is even acknowledging eth0 at runtime. So everything seems to be dialed, except that the internet connection still does not work.

i can ping the static IP address of the gentoo box, but other networks are still unreachable.

any help from you guys is appreciated. I feel so close!

If you are literally seeing a Network is unreachable error, then you are missing one or more required routes. What is the output of ip route show ; nl /etc/conf.d/net? If you are using a static IP assignment, this is normal, and you need to explicitly define your default route.

It looks like you are working not from root-user, so you should use 'sudo ip route'. By the way, what is the type of your connection to the Internet?
[EDITED] I have noticed that your default gateway is not in the same subnet. By default such configuration wil not work
