netcfg

jai134 · 2009-01-24 18:10:07

Hello. I'm trying to use netcfg to connect to the internet. When using iwconfig it's fine.With netcfg I have to do it twice to connect. Why can't netcfg connect the first time. I have had a problem about WIRELESS_TIMEOUT before and if it is that, where can I find the file to correct this?

Maybe post some configuration files so we can see what you are trying to do?

A little tip: install Archassistant from AUR, this made networking easy for me. (It uses netcfg)
When you fix your problem, post the solution too!

I have an unsecure network. This is rc.conf:
# Wireless: See network profiles below
#
INTERFACES=(wlan0 !eth0)

# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
#
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)

# Enable these network profiles at boot-up. These are only useful
# if you happen to need multiple network configurations (ie, laptop users)
# - set to 'menu' to present a menu during boot-up (dialog package required)
# - prefix an entry with a ! to disable it
#
# Network profiles are found in /etc/network.d
#
# This now requires the netcfg package
#
NETWORKS=(menu)

And this /etc/network.d
CONNECTION="wireless"
DESCRIPTION="Hemnätverket"
INTERFACE=wlan0
SCAN="yes"
SECURITY=""
ESSID="XXXX"
KEY=""
IP="dhcp"
Is that what you need. I have ath5k loaded at boot and net-profiles after network.
I get this errormessage: DHCP IP lease attempt failed. First time I use it from command-prompt. Second time it connects whithout any problem

u_no_hu · 2009-01-25 09:01:47

I think network is not needed if you are using net-profiles

jai134 · 2009-01-25 10:53:28

It made some difference. Now it connected the first time from command-prompt but not during bootup with dialog. This is my modules and daemons array:
MODULES=(mii r8169 ath5k snd-mixer-oss snd-pcm-oss snd-hwdep snd-page-alloc snd-pcm snd-timer snd !snd-pcsp snd-hda-intel soundcore)
DAEMONS=(syslog-ng !network net-profiles netfs crond hal fam alsa)

Read the wiki:
http://wiki.archlinux.org/index.php/Net … o_I_do_.3F

it is essential you provide ALL output and config files relevant otherwise the issue cannot be diagnosed.

"it doesnt work" means absolutely nothing.

what is the error you get ? i hope you have dialog installed....and increasing the timeout value a bit may help

Hi everybody,
this is my first question in this forum

I'm new to archlinux, I think it's the distro I've been looking for (I like configuring everything in text files, simple and straight solutions), BUT I have already some problems.

I'm using madwifi (modules: ath_pci, ath_hal, wlan) and DHCP for connecting to the internet (so I am connecting to my provider over wifi network),

I also get "DHCP IP lease attempt failed" and can't find any solution.

I have this in my "rc.conf" file:

NETWORKS=(mywifi)
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
DAEMONS=(syslog-ng network net-profiles netfs crond alsa hal)

(I didn't define INTERFACES, I hope this is OK)

And this in my "mywifi" file (under /etc/network.d/)

CONNECTION="wireless"
DESCRIPTION="My wifi connection"
INTERFACE=ath0
SCAN=no
ESSID=xxxxxxxxxx
DHCLIENT=no
IP="dhcp"
TIMEOUT=25
DHCP_TIMEOUT=25
QUIRKS=(preessid postsleep)

I have already tried another QUIRKS modes, removing DHCLIENT, SCAN=yes, ... nothing helps.

But now comes the interesting thing: although I get the error message at bootup "ath0: timed out, DHCP IP lease attempt failed" I can then log in as root and simply execute "dhcpcd ath0" and some seconds later the connection is up and running.

Can anyone help?

jai134 · 2009-01-25 19:41:23

Same for me. Tried to increase timeout but no success. After login it is no problem to connect as root. Can it be a problem with permissions? I will post the output from the link.

Welcome to the forums ghaad. Please don't hi-jack threads. This is about netcfg configuration.
--EDIT--
Maybe it's not any more.

My problem is solved! Yeah! But I really have no idea what happened, I just tried to reboot several times (because I also play around with another config files), and suddenly there is no connection problem any more.

ghaad · 2009-01-26 08:29:17

@jai134

Try to use madwifi instead of ath5k (if madwifi supports your card). Madwifi consists of modules ath_pci, ath_hal and wlan. Then disable ath5k (add a ! in front of it in the MODULES array in rc.conf). Take a look at my config, this now works for me. And maybe I know why I had these strange problems: maybe it doesn't make sense, but I enabled "PCI BusMaster" (or PCI MasterBus) in my BIOS. It was disabled, so I just tried to enable it. But I'm not sure if that was the problem, because I did a reboot several times then.

@skottish

I just thought it would be better to join a running topic instead of creating a new one with the same problem.

ghaad · 2009-01-26 20:38:31

I'm getting mad
I came home from work, started linux, and ... no internet connection. The same problem again. I tried for several hours to solve it (different parameters, own scripts, etc.), without success. Sometimes I even can't connect after bootup, "dhcpcd ath0" always says "time out", no matter what I'm giving in the --timeout parameter (35 seconds should be enough, but it isn't). When using netcfg there is still the same problem, but when I try to connect twice, it works (mostly), so I really have the same problem as jai134.

I have one idea which _might_ work for me and for jai134, but I don't know how to configure it: when using NETWORKS in /etc/rc.conf the connection fails (time out), BUT I am able to simply run "dhcpcd ath0" as root after startup and the connection is up and running. Soooo, where can I put this command - so it executes automatically (as root, of course) before the login shell appears?
Thanks in advance.

ghaad · 2009-01-27 11:57:47

This slowly becomes a monologue But maybe it will help someone.
I found out that the file rc.local is exactly what I was looking for. So I will try to run "hdcpcd ath0" from there.

mrmaikel · 2009-01-27 13:23:17

I have the same problem with an unsecured network.
I can connect manually, that means:

ifconfig wlan0 up
iwconfig wlan0 ESSID "***"
dhcpcd wlan0

With netcfg it won't function!

mrmaikel: What do you mean by "it won't function" - please post the output of netcfg when it "doesnt work" and your profile. Your driver helps too.

ghaad: I've seen that problem before, it's pretty annoying. Try editing /usr/lib/network/wireless.subr and changing the line:

quirk "postsleep" && sleep 1

to

quirk "postsleep" && sleep 10

If that works reliably, then you can tweak the 10 down gradually.

jai: You missed the most important output. What exactly does netcfg say when it doesnt work. It might only be one or two words, but it's the most essential thing I need to help debug your problem.

ghaad · 2009-01-27 20:19:12

This is soooo weird... It must be some kind of black magic

Netcfg caused quite a nice system crash (it killed some process which shouldn't be killed, it happened in /usr/lib/networks/wireless.subr - I forgot the line, it was > 100, but there is only one line with a "kill" command). It happened after booting (no network), so I just tried "netcfg mywifi" to call my mywifi config file again with netcfg and then it crashed. I wasn't even able to reboot then (weird numbers everywhere, I guess memory addresses). A hard reset was the only way.

Thanks for this

quirk "postsleep" && sleep 10

advice. Unfortunately it doesn't help, but at least now I know where to change some configuration.

I was now able to solve it (maybe just for today?) with the following trick:

I edited /etc/rc.local

echo Checking DHCP again...
sleep 1
dhcpcd ath0 --timeout 15
sleep 2

I guess it's not necessary to make the system sleep, but I wanted to make it more readable (else it would disappear too quickly).

In /etc/network.d/myfiwi I have the following

CONNECTION="wireless"
DESCRIPTION="My wifi connection"
INTERFACE=ath0
ESSID=xxxxxxxxxxxxxxx
SECURITY=none
SCAN=yes
QUIRKS=(predown postsleep)
DHCLIENT=no
IP="dhcp"
TIMEOUT=10
DHCP_TIMEOUT=10

And of course NETWORKS=(myfiwi) is in my /etc/rc.conf

The even more weird thing is that it FAILS while booting and "dhcpcd ath0" (in rc.local) says that it is already running - but the connection is there when I log in.

If this won't work again (tomorrow), I will definitely stop using netcfg and try some own script using iwconfig etc. (in rc.local for connecting and rc.local.shutdown for disconnecting). BTW maybe I didn't mention that I have the following wifi card / chip: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)

jai134 · 2009-01-28 17:16:49

It says "DHCP IP lease attempt failed". Is there a netconfig logfile?
