 |
|
I just installed from the Live CD (because I'm lazy  ) and the internet isn't working upon boot.
It says that eth0 doesn't exist.
When I run `ifconfig -a` eth0 doesn't appear.
Contents of /etc/conf.d/net:
| Code: | | config_eth0=( "dhcp" ) |
I don't know what else to post really. Just ask if you need anything else. |

| Maybe you should load your ethernet card's module. |

Of course, me being the idiot that I am, doesn't know what that is.
Doesn't the genkernel automatically load them? Or I have no idea.
I only have used Ubuntu and Arch (now using Arch+Gentoo) which are both more set-up by default than Gentoo.

I don't know if genkernel loads them automatically. Probably it just builds them automatically.
with you can see what modules are loaded in your system
and with | Code: | | modprobe modules_name |
you can load the module you want. |

Also, can you post this :
| Code: |
# ifconfig -a
# lspci -kv

ifconfig -a:
| Code: | lo Link encap:Local Loopback

It said that -k was a invalid option. So I just did lspci -v. If it makes a huge difference.
It's pretty long, so I pastebin'd it.

Ah, a fellow clevelander 
Apparently genkernel doesn't automatically load the necessary modules. I don't use genkernel, so I can't testify to that. From your lspci, you need the "forcedeth" module to create the eth0 interface. So if you do
| Code: | #modprobe forcedeth
#etc/init.d/net.eth0 start |
things should work.

I'll try that.
And I'm not IN Cleveland. I'm in a suburb of it. Westlake. It's a nice little city. 
I wish I was in Cleveland so I'm closer to the Rock and Roll Hall of Fame. I'm a complete headbanging metalhead.

Hi, you need to enable the forcedeth module :
http://hardware4linux.info/component/23510/
| Code: |
# find /usr/src/linux-2.6.27-gentoo-r8 -name Makefile | xargs grep -i forcedeth
|
Result :
| Code: |
/usr/src/linux-2.6.27-gentoo-r8/drivers/net/Makefile:obj-$(CONFIG_FORCEDETH) += forcedeth.o
|
So, you the module is here
| Code: |
Symbol: FORCEDETH_NAPI [=n]
Prompt: Use Rx Polling (NAPI) (EXPERIMENTAL)
Defined at drivers/net/Kconfig:1373
Depends on: NETDEVICES && NET_ETHERNET && FORCEDETH && EXPERIMENTAL
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Ethernet (10 or 100Mbit) (NET_ETHERNET [=n])
-> nForce Ethernet support (FORCEDETH [=n])
Symbol: FORCEDETH [=n]
Prompt: nForce Ethernet support
Defined at drivers/net/Kconfig:1362
Depends on: NETDEVICES && NET_ETHERNET && NET_PCI && PCI
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Ethernet (10 or 100Mbit) (NET_ETHERNET [=n])

`modprobe forcedeth` works.
System is updating. 42/255.
Could take a while. Posting this with Bon Echo.

Cool. 42/255 probably gives you time to drive down to the the Rock Hall and back.
Ironically, I've lived downtown on the west bank of the Cuyahoga for about 10 years, and I've never been to the Hall. One of these days.

i have the same problem with eth0, "not existing".
i made sure the kernel has the module built in (with Y not M). eth0 wont exist though...even though installation CD will pick it up and give me a network.
i tried putting it as M, and but i get a fatal: Module forcedeth not found.
im networkless...pls help
i dont have X installed yet so i cannot scroll through the very basic installation terminals. is there a way for me to read long messages like any scrolling option?
also i cannot ssh since i dont have a network |

did you do a make modules_install when building your kernel?
hop onto the handbook, and do that find command it mentions. You should see the .ko for that module.
If the module is found by that `find` you should be able to modprobe it. If there's some other problem with the module, it won't say "not found" - it may say it failed to load for one reason or another, in which case dmesg should give some clue as to why.

sure, heaps of ways. easiest:
| Code: | | lspci -v > lspci.txt |
then
if your network is working on the livecd, and indeed it's the forcedeth module, you should be able to do
and see the module listed. the lshw command should confirm as well (you have to emerge lshw)
at any rate, let's find out first if you have the module bulit at all. Do that `find` command they mention on the handbook, see if it's listed. If not you need to make modules_install, add the module name to /etc/modules.autoload.d/kernel-2.6 and carry on about ya bizness

thx for response
the following are run from a chrooted environment from minimal CD:
| Code: | | lshw | grep forcedeth |
gives
| Code: | configuration: autonegotion=on broadcast=yes driver=forcedeth driverversion=0.61 duplex=full ip=192.168.0.11 .....
|
and the same for the other NIC.
| Code: | lsmod | grep deth
forcedeth 57484 0 |
does not return anything with forcedeth, i looked inside the text file like you showed me.
i did the find command, but there is no forcedeth in there either (i loooked in my own kernel, not the CD's). it makes sense though because i have it set up as built in (with Y) at the moment.
i re-run the commands by logging in w/out chrooting booting from my own kernel (no network, no eth0)
| Code: | | lshw | grep forcedeth |
does not return anything
does not return anything
does not return anything with forcedeth, no mention of drivers in use for ethernet cards, but this was same response when chrooting.
| Code: | | find /lib/modules/2.6.29-gentoo-r5/ forcedeth |
says forcedeth: no such file or directory.
now again, config_forcedeth=y in my .config, not =m
i have network now, because i have it running from minimal CD
i still need help
thank you. |

h2sammo,
Please post your lspic output.
The -k option is only useful if the device is working. It tells what kernel module is in use.
forcedeth (or any other module) only appears in lsmod when its loaded. Modules are only in /lib/modules/`uname -r`/... when they are configured in the kernel as <M>. when they are set as <*> they are included in the bzImage file, thus cannot be modprobed.
If you have made the module you really need, either as a module or into the kernel and the network device does not exist, you have messed up the kernel build or install. Check with The date/time is the build date and time of the running kernel. Does that look right ?

uname -a gives my latest kernel. so thats ok there
the way i make and install the kernel is with | Code: | | make && make modules_install |
and then i copy the bzImage to /boot
i follow the compilation process on the screen and i see forcedeth.o being listed during the compilation...however my eth0 is still absent. how do i make sure that when i make changes to my kernel, the old kernel gets replaced with the new one and used for the boot?
help |

h2sammo,
The lspci you posted does not contain any Ethernet lines. Please check that.
Either you don't have any Ethernet, you missed it in lspci, or Ethernet is disabled in the BIOS
forcedeth.o will be made regardless of it being seleted as <M> or <*>
Only <M> will get you a forcedeth.ko file

h2sammo,
Sorry about that.
Can you post your kernel .config file please. email it to me if its too big for the forums or a pastebin

how can i get it off my machine? i dont have network, cant ssh.
maybe give me some pointers as to what to look for and i can report that bit back.
edit: i have found this nifty command, which lets me search inside .config and outputs results, its much less for me to type, ex:
| Code: | grep CONFIG_FORCEDETH /usr/src/linux/.config
CONFIG_FORCEDETH=y
#CONFIG_FORCEDETH_NAPI is not set |
what else should i lookf for? is there anythign which can negate this instruction? |

h2sammo,
Boot the liveCD so you have network
Mount your filesystems as if you were going to chroot. Do not chroot
Your kernel .config is now at /mnt/gentoo/usr/src/linux/.config so you can move it over the network
If you chroot, you can do emerge wgetpaste then use wgetpaste to put things onto a pastebin.
Kernel .config files may be too big for that in one go but if it works (from inside the chroot)
| Code: | | wgetpaste /usr/src/linux/.config |
is the command. Post the URL it gives you.

The password is auto scrobbled for security, nobody knows that password and it changes on every reboot.
You just have to change it for any known password. Use the passwd command for that.
Cheers!
