Network problems

[johpe916]

Hi,

I'm having a strange problem with my network.
I installed Gentoo 1.4 on a celeron, with a Realtek 8139 network card.
Everything worked ok. I bought an Athlon XP and a ECS K7S6A motherboard with the sis745 chipset. Before the change I recompiled my kernel with support for Athlon processors. At boot everything except network worked.

The strange thing is that the card is found as eth0, but it won´t take the dhcpcd command. If I do
:dhcpcd eth0, it takes a while, the command finishes but dhcp isn't on.

I recompiled the kernel a couple of times bot nothing changed. Then I tried the gentoo 1.2 iso and it finds the card and now it will accept dhcpcd, and the network is there.

I read a post on geento mailing list about someone else having the same problem. Does anyone have any ideas? What am I doing wrong? Is my kernel lacking some functionality?

If it works with the kernel on the install CD, you can compare your kernel's configuration file (in /usr/src/linux/.config), with the .config file used to build the install CD. If you can find the key difference, and can spare a moment to let us know, it will maybe help other people with your problem.

Welcome to the Gentoo forums, by the way.

Same problem here except its from the installed system of 1.2 downloaded from the net. Some times I will be able to fire up no problem but sometimes I even LOSE the lease on my address prematurely? Im on a Road Runner system here in Maine and usually its pretty good. (800+ KB/sec download) But recently the above mentioned crap occurs. Im not sure if its the new Toshiba modems they sent in the mail or Gentoo's DHCPCD thngy. Odd no?

Ok, got the answer.

I needed to enable the "mmapped IO" option in the kernel
Don´t know what it means or what it does but it solved my problem

Just felt like sharing.......
