Hi all,

After a fresh install, my system start well. Eth0 up. But i have no network, i can only ping myself on localhost and on my ip adress .... really don't understand what append.

My config :

Laptop ACER 5810 TG
Kernel 2.6.31-r6 w86_64
Attansic network card, the card works well with atl1c module on livecd and debian squeeze.

install profile : desktop

Kernel compiled with genkernel (just a 'genkernel all' for first.... waiting that problem was solved to tune it)

At boot, module load well, eth0 up, i can make an static config by hand without error message, but no network ! Can't ping my router. With DHCP, same thing, doesn't work.

I try to search some identical case in google, but i didn't find anything


Thanks for the help (and sorry for my english... french guy)


Hadrien

Hi Hadrieno,

so give us more info to give you better help.
Did you follow the Gentoo-handbook regarding setting up your network, cause the net-setup ethx works only on the live-cd or sysrescd, if you used it before.

Here is an example of my static IP configuration behind a Router which did the connection for me.
You see what you get if you enter ifconfig, route etc. as below.


Code:

ifconfig -a

eth0      Link encap:Ethernet  HWaddr 00:1b:b9:b2:17:50
          inet addr:192.168.69.2  Bcast:192.168.69.255  Mask:255.255.255.0
          inet6 addr: fe80::21b:b9ff:feb2:1750/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:310336 errors:0 dropped:0 overruns:0 frame:0
          TX packets:197319 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:436841277 (416.6 MiB)  TX bytes:15322484 (14.6 MiB)
          Memory:f9fe0000-fa000000

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:105 errors:0 dropped:0 overruns:0 frame:0
          TX packets:105 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:8144 (7.9 KiB)  TX bytes:8144 (7.9 KiB)

localhost andy # route

Kernel IP routing table

localhost andy # cat /etc/conf.d/net
# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d.  To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).

config_eth0=( "192.168.69.2 netmask 255.255.255.0 broadcast 192.168.69.255" )
routes_eth0=( "default via 192.168.69.1" )


Much success, Andy.

Yeah, i use the Handbook, but i didn't use net-setup. On install i just let dhcp doing his job, and all works fine.

At boot up, dhcp can't keep an adress, so i used basic configuration with ifconfig + route and modify resolv.conf.

So i find !

Explanation :

I took look on my /var/log/message and i see lot of errors like :

nommu_map_single: overflow 137c1b0d0+8 of device mask ffffffff
nommu_map_single: overflow 136c047c0+64 of device mask ffffffff
nommu_map_single: overflow 135cb8648+8 of device mask ffffffff
nommu_map_single: overflow 136c047c0+64 of device mask ffffffff
nommu_map_single: overflow 135cb8648+8 of device mask ffffffff
nommu_map_single: overflow 136c047c0+64 of device mask ffffffff


After some search on google, i found this :

https://bugzilla.redhat.com/show_bug.cgi?id=532582


And solution was to add : intel_iommu=off
in kernel boot up option in grub.conf....


Sorry for the topic.......

U can close the topic, i will change the title for others people who maybe will have same problems.


Have a nice day !

Fine that you could solve your problem by yourself!

As i wrote my first post, your second one was not readable for me...


Please edit your first post and add [solved] to the subject / title.

Andy.
