 Posted: Thu Oct 09, 2008 2:39 am Post subject: Wireless using local at default level, how at boot level? |
 |
|
Wrote a small script to bring my wireless up using wpa_supplicant. Tested manually and it works fine.
Put the script to /etc/conf.d/local.start and added local to my default runlevel.
gives
| Code: |
alsasound | boot
bootmisc | boot
checkfs | boot
checkroot | boot
clock | boot
consolefont | boot
dbus | default
fbcondecor | boot
hald | default
hostname | boot
ivman | default
keymaps | boot
local | default nonetwork
localmount | boot
metalog | default
modules | boot
net.lo | boot
netmount | default
ntp-client | default
openvpn | default
rmnologin | boot
urandom | boot
vixie-cron | default
xdm | default |
Now at boot it starts my wireless (eth2, don't ask me why), and tries scanning for a suitable wireless router. Finds nothing, and issues an error: failed to configure wireless for eth2. Also my ntp-client fails as well as there is no network. System continues booting and at some point local kicks in and I get my wireless. At that point, if I issue ntpdate manually it will obviously work.
Now the question is how get use local right a way and get wireless running before anything else? |

Can you post this :
Maybe you can do somehting with netplug or ifplugd. |

I had the exact same issue.
My hack was to remove ntpdate from the auto start procedure (using rc-update del ntpdate) and append it to the end of my script called from /etc/conf.d/local.start.
The trick for me was to insert a "sleep 30" before the call to ntpdate to allow enough time for wpa_supplicant to do its stuff.
BTW my solution was a little different to yours. I created a symlink from /etc/init.d/net.lo to /etc/init.d/net.wlan0 and edited /etc/conf.d/net appropriately (as I'm sure you have too  ). My local.start script just sleeps and calls ntp-client (in my case). The advantage of this is that all the network related daemons (dhcpd, sshd etc) get delayed automatically until wpa_supplicant has associated with the router. Quite why the startup script for ntpXXX isn't is intelligent as the other network daemon scripts is another question ...

I moved everything to /etc/conf.d/net, but I cannot make it work the way I wanted.
My new /etc/conf.d/net:
| Code: | modules_eth0=( "ifplugd" )
config_eth0=( "dhcp" )
dhcpcd_eth0="-t 5"
modules_eth2=( "wpa_supplicant" )
config_eth2=( "dhcp" )
dhcpcd_eth2="-t 60"
wpa_supplicant_eth2="-Dwext -c /etc/wpa_supplicant/wpa_supplicant.conf"
wpa_timeout_eth2=60
preup() {
if [[ ${IFACE} == "eth2" ]]; then
if ifplugstatus | grep -q 'eth0: link beat detected'; then
ewarn "Wired connection on eth0 detected, aborting configu$
return 1
fi
fi
}
postup () {
if [[ ${IFACE} == "eth2" ]]; then
iwconfig eth2 txpower on
fi
} |
Both network interfaces are symlinked to net.lo
| Code: | | ls -l /etc/init.d/net.* |
| Code: | lrwxrwxrwx 1 root root 6 Aug 3 19:29 /etc/init.d/net.eth0 -> net.lo
lrwxrwxrwx 1 root root 6 Jun 24 2007 /etc/init.d/net.eth2 -> net.lo
-rwxr-xr-x 1 root root 30696 Aug 3 19:29 /etc/init.d/net.lo |
It drives me crazy.
net.eth0 and net.eth2 should I piut them to default or boot level? Neither?
net.lo is already on boot level.
Could you please post the corresponding files from your setup?
What do you use ifplugd or netplug?
Thanks mate. |

net.eth0 and net.eth2 should be in the normal startup level not boot
My /etc/conf/local.start script looks like this
| Code: |
GREP_CMD="grep 'inet addr:169.254.'"
/sbin/ifconfig | grep "$GREP_CMD" > /tmp/inetaddr
if [ -s /tmp/inetaddr ]; then
echo "Sleeping for 60 seconds to let WiFi Connect"
sleep 60
fi
rm /tmp/inetaddr
/etc/init.d/ntp-client start
|
I only want my wifi to start if there is no cabled connection on eth0. This script checks the IP address on eth0 and if it isn't set to a valid address, pauses for 60 seconds to allow the wifi router to associate. I have a slider switch on my HP laptop to activate the wifi card on and off. I leave it off unless I need to use wifi; the standard net.eth2 script knows if it is off so doesn't try to associate.

I am trying to avoid a 169.254.x.x ip address as all network services like ntp or samba will start on eth0 instead of eth2 (wireless) .
I want my eth0 down when cable is plugged. Not up with a bogus 169.254.x.x, but actually down.
eth2 (wireless) should be up only if eth0 is down.
As soon as I plug the cable eth0 should be up, and eth2 should be down.
Unplug, eth0 down again, and eth2 up.
Look at my /etc/ifplugd/ifplugd.action a few posts up how I am trying to manage it.
But so far no cigars  |
