Network DHCP Issues

Hi everyone, I've just installed gentoo, I followed the installation instructions to get gentoo working in my box, everything it's going fine, my network card it's recognized and all that stuff, the only problem that I have it's that I can't get dhcp to work. when my system boots and the net.eth0 starts it says the next:

*Starting eth0
* Bringing up eth0
* dhcp
*No loaded modules provide "dhcp" (dhcp_start)

I actually get connected to the internet through a router that manages dhcp.

Maybe I forgot to do something during the installation but till now i haven't found the error yet, any help will be really apreciated, thanks.

Did you emerge dhcpcd?

I have the same problem. I did re-emerge dhcpcd but no luck. This happened after upgrading my base system to 1.12._pre1_r1

I have tried downgrading dhcpcd from 1.3.22_p4_r11 to 1.3.22_p4_r5 but still no luck

drakos7 · emerge =baselayout-1.11.13

Occurs here as well. After upgrade to baselayout.
Re-emerging dhcpcd 1.3.22_p4-r5 did not fix it.

FIXED

cgmd · emerge =baselayout-1.11.13

Same happened to me after emerge -uDN world upgrade to baselayout-1.12.0_pre1-r1. This produced a boot failure:

Perhaps you should investigate ifplugd. That is how I (think I) avoided the boot lock up issue. I am on a laptop so I do not always have a connection. When dhcp failed in ifplugd, the boot process continued so I did not need to resort to a Boot/LiveCD.

Mine, too, is a laptop. I have ifplugd operating as it should, now that I downgraded baselayout (i.e. I don't need a network connection to boot the laptop). I have no idea why I locked up after the baselayout upgrade.

Question... What can I do to try to prevent the lock up with my next upgrade??

I can only assume that I survived because my hardline eth0 is set up for ifplugd. Sorry I cannot be of more help.

Thanks for the input guys. The only thing i have noticed is that my whole machine is incredilbly slow to bootup. It takes about 15 minutes now. I have to push <ctrl>-D or <ctrl>-C to get it to get past just about every step after the network. I havent downgraded my base layout yet. I am ging to do that now.

My network config for eth0 and eht1 currently points to net.lo

Mine are as well:

They are meant to point to net.lo. It's just that some have deleted and recreated the link to fix the problem.

well i got close to the same problem. I also emerge -uD world and my internet connection is borked. I noticed also I emerged the baselayout. When I start it says
* Starting eth0
* Bringing up eth0
* up
* No loaded modules provide "up" (up_start) [!!]

My problem is that I use pppoe to connect and even tho I can bring up eth0 directly, I still cannot connect to downgrade the baselayout. I tried booting from the liveCD but I still cannot connect, which is really strange to me since its the same CD I used to get it going to begin with

Any help appreciated.

I transferred the files I needed (from one of the gentoo dist mirrors) to a usb flash drive and then tossed them in /usr/portage/distfiles. That is how I was able to go back to the previous baselayout.

can you post the link to the baselayout-1.11.13?

I am surprised.. the new version of baselayout is marked unstable in portage yet my emerge which includes no flags about ~x86 still downloaded and installed it anyways. Maybe that why my system breaks and I have to fix it everytime I do an emerge.

drakos7 · Posted: Fri Jul 22, 2005 2:46 am Post subject:

grep http /usr/portage/sys-apps/baselayout/baselayout-1.11.13.ebuild

So point to http://dev.gentoo.org/~azarah/baselayout/rc-scripts-1.6.13.tar.bz2

Not intuitively obvious. Looks like 1.12 gets baselayout-1.12 which is more consistent.

well i have baselayout-1.11.13 now but its still not working. I have been playing around with pppd and pppoe to try and find the magic combination to make that work. So far no luck. If I try to start dhcpcd it will not come up for whatever reason. The interface comes up (i can see with ifconfig) but it goes right back down. I can do ifconfig eth0 up and keep it up but thats not the real issue. I just dont know why pppd is not being used. Normally when I run adsl-start it bring up everything automatically. Can someone else that uses pppoe please post the contents of their /etc/ppp/pppoe.conf and also their /etc/conf.d/net files. I would really appreciate it!

for those using dhcp... emerge dhcpcd solved it for me... I really dont know, why portage was thinking it wasnt installed...

ok thanks. I still cannot connect tho. I think its an issue with pppd. When I try to start I see this in the syslog...
pppd: pppd 2.4.2 started
pppd: Couldnt get channel number: Input/Output error
pppoe: ioctl(SIOCGIFHWADDR): Session 0: No such device
pppd: Exit.
ADSL-Connect: ADSL-Connection lost; attempting reconnection.

repeats

I am guessing the SIOCGIFHWADDR error is a problem with the ethernet card or something in the code for the driver is borked. I will say that the network connection had been fine up til the last emerge. Since Ive tried to use old kernels, re-compile kernels and use, etc etc and I cant get it going again.. not even from the live CD which is quite odd to me. At any rate I use Intel nic card.. its on of those built in jobs on a laptop, so I am using the intel kernel modules which have always worked. I also had support for the 8139too and ne2000 support selected as modules. I would also be curious to know if anyone else having this connectivity issue dhcp, or otherwise is also using the 8139too or Intel drivers. If there was a problem in the code for either or these then the module would have been built and installed and well that would explain a few things. Maybe thats a code problem since there was a new kernel 12-r6 in the last emerge world.

Has any one seen or know what the above error is from?
