what does it list when you type ifconfig.

if it does not list eth0 then type. ifconfig eth0 up
dhcpcd or dhclient eth0

and that might do it. If this is the case you need to add eth0 to you run time default. rc-update add net.eth0 default

**genesus** · 03-20-2005

ifconfig still posts the same output that I have listed in an above, i think the first, post. I have net.eth0 added to my default run time. and when I manually try I get the output

Code:

*Bringing eth0 up via DHCP....                             &#91;!!&#93;

and anytime I try to do anything with eth0, such as ifconfig eth0 up I get the output

Code:

eth0&#58; unkown interface&#58; No such device

so I figure that I have to somehow add the device and assign the eth card to be eth0...

confused and now a bit dazed,

thanks for your time,

John

try this in a vt that is not chrooted

Code:

net-setup eth0

also try

Code:

net-setup eth1

sometimes i dont know why but it gives it eth1 even though there is only 1 nic in the box.... then in that same vt

Code:

cp -L /etc/resolv.conf /mnt/gentoo/etc/resolv.conf

then go back to your chroot`d vt and check

Code:

cat /etclresolv.conf

to see that the nameserver info is there then ping something[/code]

Code:

-bash&#58; net-setup&#58; command not found

Ah, looks promising, but the command is not found, shoul I use a live cd, chroot, and emerge net-setup, or is the app of another name? Or is there a more manual way to do this?

Thanks for your time,

I appreciate all your help so far,

Hopefully we'll get this thing working soon

thanks,

John

wait
i thought u were installing
if u have a full install then simply edit your

Code:

/etc/conf.d/net

and asfar as' netmount' mine borks everytime but works....i'll fig that out someday

**genesus** · 03-20-2005

not sure what it is supposed to look like but my /etc/conf.d/net looks like this, I left out comment sentances but left in commented options in order to keep this post with some degree of brevity.

Code:

iface_eth0="192.168.0.2 broadcast 192.168.0.255 netmask 255.255.255.0"
#iface_eth1="207.170.82.202 broadcast 207.0.255.255 netmask 255.255.0.0"

iface_eth0="dhcp"
#iface_eth0="-HD"

#alias_eth0="192.168.0.3 192.168.0.4"
#broadcast_eth0="192.168.0.255 192.168.0.255"
#netmask_eth0="255.255.255.0 255.255.255.0"

so what do I configure manually. I just installed and had network capability within the install environment, which I did through slax via chroot, following the instructions for gentoos alternate install method, so I guess that is why net-setup is not working. There must be a way to turn the dev on and assign its designation, i know this isn't the correct terminology, to be eth0.

Not sure, seems like I've tried everything, but it will work eventually.

Thanks for your time,

John

I have a strong feeling that you might have not compiled in the support for your nic or at least done so as module and the module hasn't been loaded.

Please check the kernel settings and make sure you have the proper network driver compiled in as either builtin or as a module. When it is done as a module, of course, you have to make sure to load it before you use it.

AFAIK, the interface names are registered when the kernel detects the hardware and loads the proper driver for it. So, I would hope that you forgot to load the driver, because if you do have the driver and still it is not working, then I have no idea

lspci only shows what stuffs are actually present and they only pull the identification strings from the device itself. Which means is that just because it shows up on lspci doesn't mean it is correctly "recognized" by the kernel. It's just showing what's there. Loading a proper driver for it is a different matter.

to see what modules are currently available

Code:

modprobe -l

to load a specific module

Code:

modprobe <module-name>

to check currently loaded modules

Code:

lsmod

to check the current kernel settings (assuming /usr/src/linux is properly symlinked)

Code:

cd /usr/src/linux
make menuconfig

to compile kernel & install modules

Code:

make && make modules_install

As long as you have correctly set up dhcp server running at the other end of which your computer is connected to, be it another *nix box or just a stock router, your network settings look just fine. It even assumes dhcp when there is no settings present, which is how my /etc/conf.d/net is (it's an empty file!!!)

hope you have luck w/ your setup.

networkless gentoo is, quite frankly, useless LOL

I agree with ajck check under device drivers > network support > then find you lan settings and make sure you have then checked. If your not sure which ones try a bunch and see if it works.

ok, I'll look around at the kernel config menu and recompile and post the results, thank guys, this looks promising, already found xircom drivers in the kernel...maybe

take care,

John

**genesus** · 03-20-2005

ok I thought that I was onto something, the xircom drivers were not seleced in my menuconfig file, so I selected them, compiled the kernel, reboot, still same error, no netmount and eth0 not recognized. The xircom drivers were under the pcmcia section and not the section ethernet 10/100. So maybe that is the problem, do I unselect ethernet 10/100 and all devices if my card is pcmcia, which I think it is?

Getting closer I can feel it!

even manual bringing up of eth0 fails.../etc/init.d/net.eth0 start looks like it'll work but still returns the damn [!!]. I even tried selecting all ethernet drivers, recompiled, still fail on netmount and bringing up eth0 via DHCP...hmmm

thanks guys, anymore ideas?

John
