Posted: Mon Sep 09, 2013 5:37 pm Post subject: [SOLVED] network stopped working with ipv4

Hello,

I use my laptop mainly on two networks (home and office). Everything worked fine until the last 'emerge -auvDN world', which I did on Friday.
Now my network doesn't work anymore in the office; everything still fine at home.
wicd-curses, which I usually use to manage the network, says it cannot get an ip.
First I tried to revert back those packages that were updated and that could be related to this network malfunction:

Code:

From /etc/portage/package.mask
# trying to revert back network
=virtual/perl-libnet-1.230.0
=sys-kernel/linux-headers-3.9
=sys-power/powertop-2.4
=net-nds/openldap-2.4.35
=sys-power/upower-0.9.21

This didn't help (at the bottom of this message is full list of packages that were updated during the last emerge).
Digging in the log files, I see that the home network is using ipv6, and the one in the office is using ipv4.
I am quite lost. I am attaching below an excerpt of the wicd log, and the corresponding section of /var/log/messages.
I should also mention that I am using a lenovo usb dongle with the 'asix' module; however, in the office I am unable to use both the wired network and the wireless one.

Is this a problem with ipv4 vs. ipv6? How can I debug it and fix it? when I try to do by hand

Code:

ifconfig eth1 down
ifconfig eth1 up
dhcpcd eth1

I get a "network unreachable" error. I guess it's because of the "setting false ip" I see below?

Many thanks for any suggestion you might have,

Davide

First, lets:

Code:

cd /usr/src/linux
make clean
make menuconfig
Networking Support --->
Networking Options --->
< >The IPv6 protocol ---> {disable this one}
exit menuconfig
recompile kernel and copy to /boot (see Gentoo instructions for this)
reboot.

Do above unless you are using systemd!

Your working IPv6 Router is accepting IPv6 requests but the logs indicate you are receiving an IPv4 Address:

Code:

eth1: sending IPv6 Router Solicitation
2013/09/09 09:15:37 ::
2013/09/09 09:15:37 :: dhcpcd[29154]: eth1: broadcasting for a lease
2013/09/09 09:15:37 ::
2013/09/09 09:15:41 :: dhcpcd[29154]: eth1: sending IPv6 Router Solicitation
2013/09/09 09:15:41 ::
2013/09/09 09:15:43 :: dhcpcd[29154]: eth1: offered 192.168.0.178 from 192.168.0.1

which means it defaults to IPv4.

now edit /etc/portage/make.conf, or /etc/make.conf depending on system age, and remove ipv6 from the USE variables. Then

Code:

emerge -uDNav world

This will effectively remove IPv6 support from your system..., thereby forcing both networks to use a baseline of IPv4.

Thanks! I have re-compiled my kernel after disabling the ipv6 support.
One thing that I noticed is that I did not have any ipv6 keyword in my make.conf (see below).
Perhaps that was the cause of my problem?
I can get an IP at home, and I don't see the 'IPv6 Router Solicitation' messages anymore (see below).
Now I am going to try again in the office.
I will post an update soon...

THANK YOU, eyoung100!!!! you rock! That was it. My network is now working again at home and in the office I don't even remember ever enabling ipv6 in my make.conf, and it would have taken me months to guess it without your help Best wishes, Davide

IPv6 is going to be REQUIRED for systemd. As such , it's been enabled by default in the newer kernels, as most people cannot tell a difference, unless they have an older router, which was your case.
