network starting fail

Fou · 2009-10-23 02:18:27

Hi all,

I have 3 partitions on my hard drive. Vista, Arch linux and Ubuntu. Sometime when i'll go with Arch, i see some process failling on the screen - i'm REALY SORRY for my BAD english - i got no opportunity to practice
Network starting is failling sometime. other stuff fail to but i can't see which one. How can solve my problems with this ? I'm totally lost in the log files. Which one of this logs i should see first ?

Thank you

You can review the boot messages by adding a line to your /etc/rc.local:

ok thanks.

But, my internet connection work randomly, about 25% of the time. I don't know what i'm supposed to do ! !

For your internet connection to work, you first need a working network connection. What is the status of your network connection at that time? Do you receive an IP address and is ping working? Are you using static or dynamic IP addresses? What does /var/log/messages.log say?

Thank you for your rapid reply.

My network connection work. It work on my ubuntu partitions. When my internet does not work properly, i have no ip address and i cannot ping anything at all. I use dynamic IP addresses. Sometime, when i reboot, starting network fail and i have no network working. I reboot again, and then, everything work fine.

I'm searching right now on message.log, but sincerly, i don<t realy know what i'm looking for.

thank you

You should be looking for messages from dhcpcd, since this daemon acquires the IP address on boot. It may be faster if you look into /var/log/daemon.log, since thats the place all daemons put their messages in.

Consult this wiki article about dhcp configuration:

http://wiki.archlinux.org/index.php/Configuring_network

There is a troubleshooting section on the subject of dhcpcd not starting at boot. You may try the suggested workaround.

in daemon.log, i have only one log about dhcpcd and it is realy not clear.......

localhost dhcpcd: timed out

the rest in this log is this...

localhost init: Id "x" respawning too fast: disabled for 5 minutes
localhost init: cannot execute "/usr/bin/kdm"
localhost init: cannot execute "/usr/bin/kdm"
localhost init: cannot execute "/usr/bin/kdm"
localhost init: cannot execute "/usr/bin/kdm"
localhost init: cannot execute "/usr/bin/kdm"

again and again and again..........And i don't use kde or kdemod i'm on gnome. wierd:mad:

Did you try the suggested workaround from the wiki, adding

dhcpcd -k eth0 dhcpcd -nd eth0

to /etc/rc.local?

MariusEriksen · 2009-10-25 10:39:48

Are you using wifi? Maybe you are near the border and sometimes it fails to associate to the AP. Anyway, how are you starting it at boot?

Fou, give some real information, "it doesnt work" tells us nothing.

How is it configured? Post any relevant configuration files here.

What is the exact error message?

Arch Linux
