PostPosted: Sat Nov 22, 2014 3:52 pm    Post subject: Network does not work with Realtek RTL8111/8168/8411 ... Reply with quote

I did a fresh installation of Gentoo. My network card is Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06) (lspci list).
Kernel is gentoo-sources-3.14.14. Little old, but i copy my old config. I install also linux-firmware-20140603.
Openrc is sys-apps/openrc-0.12.4 USE="ncurses netifrc pam tools- unicode -debug -newnet (-prefix) (-selinux) -static-libs". dmesg show renamed network interface eth0 to enp3s0.
I did symlink net.enp3s0 --> net.lo and add rc-update add net.enp3s0 default. I install also dhcpcd.

lsmod show
mii 3803 1 r8169 and
r8169 55812 0

Am I forgetting something? Before connecting the work with these settings.
How do I make fixed network settings? My router ip is 192.168.11.2
is config_enp3s0="192.168.0.2/24" or config_eth0="192.168.0.2/24" ?
Why udev rename eth0 to enp3s0?

my make.conf is now
CFLAGS="-O2 -march=bdver1 -mprefer-avx128 -mvzeroupper -pipe"

CXXFLAGS="${CFLAGS}"
CHOST="x86_64-pc-linux-gnu"

Why udev rename eth0 to enp3s0?
As part of its highly contentious and often troublesome "Predictable Network Interface Names" feature, udev renames your devices based on their physical characteristics. There are many threads discussing both the technical value of the feature and the wisdom of this default. You should decide whether you want to use the udev mangled name or the kernel assigned name, configure udev accordingly, and then configure your network.

If you want to use a fixed IP address, then you should set config_interface="chosen-fixed-IP/24". In most cases, you will want the fixed IP to be on the same subnet as your router. Usually, you can set config_interface="dhcp" and let your router assign an appropriate IP address.

If you need more help, please explain exactly what does not work and why you believe the observed behavior is wrong. For example, do you have trouble resolving names? Can you connect over TCP to a known valid IP address on the Internet? Can you connect over TCP to a known valid IP address on your LAN?

I use stage3-amd64-20141113.tar.bz2. Maybe some older stage3 is better?
The network does not work. also ssh don't work. I would like to continue with the installation ..

Sakarias,

Code:
Nov 22 21:38:03 localhost kernel: [ 12.755354] r8169 0000:03:00.0 enp3s0: link up
Nov 22 21:38:08 localhost dhcpcd[1738]: enp3s0: using IPv4LL address 169.254.250.116
Nov 22 21:38:08 localhost dhcpcd[1738]: enp3s0: adding route to 169.254.0.0/16


shows that dhcpcd failed to get an IP address from your router for some reason so it assigned itself a link local address.
it only waited 5 seconds, thats a very short timeout.
The only use for link local addresses is in ad hoc wireless networking.
This at least shows your kernel is OK as enp3s0 exists.

Lets rule out a few trivial things. Do you only have a single wired ethernet port on your motherboard?
Its quite possible for the liveCD and your install to see multiple interfaces in different orders, so you may need to try all your interfaces.
However enp3s0: link up, says that there is a cable in enp3s0

Next step. Given that your router ip is 192.168.11.2. lets assign an IP statically.
Code:
ifconfig  enp3s0 192.168.11.101/24
will do that. If that worked
Code:
ping 192.168.11.2
should work too.
You will not get to the internet yet, that needs another setting
Code:
route add default gw 192.168.11.2

Does
Code:
ping 74.125.230.64
work?
Thats google.com.

If it fails tell what happens and post the output of
Code:
route -n

Is 192.168.11.101/24 right? Can i try 192.168.11.1/24?

route add default gw 192.168.11.2

and ping 74.125.230.64 don't work

route -n > route1

file /etc/conf.d/net missing?

My second gentoo installation works and
get ip 192.168.11.2 from router with dhcpcd.
And i use same kernel! gcc is new stable 4.8

Sakarias,

Code:
PING 192.168.11.2 (192.168.11.2) 56(84) bytes of data.
From 192.168.11.101: icmp_seq=1 Destination Host Unreachable


Shows that there is no TCP/IP link from your PC to your router. Until that is fixed, networking won't work.
Your routing table is correct.

/etc/conf.d/net missing is OK. The system will use dhcpcd, which we have seen in your earlier posts.

A driver issue is not ruled out but its easier to test for hardware.
Can you prove that the port on the router and ethernet cable works by testing with another PC.
If thats good, can you try another network card in yor PC.
Try another cable and router port anyway.

The output of lspci and lspic -n may be useful. Just the Ethernet lines.
Code:
0a:06.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8169 PCI Gigabit Ethernet Controller (rev 10)
0a:06.0 0200: 10ec:8169 (rev 10)
In my case they are identified by the 0a:06.0 at the start of the line.

Your dmesg output might show useful information too. That will not fit in a post but you can put it onto a pastebin site and post a link.

My compurer and router work. I'm just typing with same computer, but another system. I have new 2T hardisk and like instal light Linux with vdr and xbmc.

cut from dmesg...

I installed Gentoo on several occasions. Now, I have forgotten something and I came up with what would be wrong with.

Shows that enp3s0 was able to get an IP address using dhcpcd.
Its not clear if tis is Gentoo or your other operating system.
That all works.

Assorted Realtek cards take firmware patches to make thew work properly/better. I'm not aware of any that must have firware loaded to work at all.
The firmware is provided by the linux-firmware package. The r8169 driver must be compiled as a module to pick up the firmware.

shows the interface going down, the kerel being unhappy abount it and finally the interface comming back up. This time without an IP address.

This might be a power management issue. If you can, turn off any Ethernet power managemet . Thats a guess though.
