location of wireless conf in Slackware

Hey all, I've got my Linksys WUSB11v2.6 working grrreat in slackware (kernel 2.4.26). But, now that it is working, I'm afraid to restart. I want to look and see that the iwconfig settings will reload, and that the ifconfig settings will reload.

Normally, network settings are stored in /etc/rc.d/rc.inet1.conf, but I guess settings for wlan0 aren't in there. And that doesn't say anything about iwconfig settings.

I'm using the sourceforge Atmel driver, and I already know that the module loads at boot time with no problem.

So, where is ifconfig wlan0 pulling its configuration info from? And where is iwconfig wlan0 pullings its configuration from?

You can edit:
/etc/pcmcia/wireless.opts
or
/etc/rc.d/rc.wireless.conf

I'm using orinoco_cs vs. Atmel. Not sure if that changes anything.

I checked both those files and they didn't have any settings configured. I'm thinking that means that isn't where the config is stored.

My card is USB, so I doubt the /etc/pcmcia would be the answer...

I still haven't restarted, but I suppose I can get it working again easily when I reboot. Thanks for trying, though.

You'll have to manually enter in your wireless settings into rc.wireless.conf, then make sure that rc.wireless is executable.

My own method is from the Slackware 9 days before the rc.wireless script was added, using a slightly different script I found somewhere (but it's the same concept):

/etc/rc.d/rc.wlan0

Code:

#!/bin/sh
   #
   # rc.wlan0
   #

   CHANNEL=1
   ESSID=""
   INTERFACE="wlan0"
   IPADDR=""
   KEY="" 
   MODE=""
   NETMASK="" 

   # Determine broadcast and network addresses from the IP address and netmask:

   BROADCAST=`/bin/ipmask $NETMASK $IPADDR | cut -f 1 -d ' '`
   NETWORK=`/bin/ipmask $NETMASK $IPADDR | cut -f 2 -d ' '`

   # Set up the WiFi card

   echo "Configuring ${INTERFACE}:"
   /sbin/ifconfig ${INTERFACE} ${IPADDR} broadcast ${BROADCAST} netmask ${NETMASK}
   /sbin/iwconfig ${INTERFACE} essid ${ESSID}
   /sbin/iwconfig ${INTERFACE} channel ${CHANNEL}
   /sbin/iwconfig ${INTERFACE} mode ${MODE}
   sleep 2
   /sbin/iwconfig ${INTERFACE} key ${KEY}

Just insert your appropriate settings, chmod +x, then add a call to this at the end of your rc.inet1:

Code:

###################################
### Wireless Card Configuration ###
###################################

if [ -x /etc/rc.d/rc.wlan0 ]; then
   echo "configuring wireless card..."
   /etc/rc.d/rc.wlan0
fi

# End of /etc/rc.d/rc.inet1

Hope that helps.

Thanks, that did it.

Actually, I still need to go in and make some changes. See, I had rc.inet1 bringing up the wlan0 interface from rc.inet1.conf, but that was giving eth0 and wlan0 the same IP. Easy to fix if I just put the ifconfig line in rc.wireless. Cool.

I restarted and all is well, except the nameservers I put in /etc/resolv.conf didn't stay there. (Oh yeah DHCP no worky with my current setup). So I reentered the nameserver info, made a backup file, and hopefully it'll never happen again, but I'll be ready if it does.

Thanks again.

If you set the essid before dhcp is executed it should work.

Okay, I might try that. But I don't mind having a static IP; it makes it easier to forward ports from the router. Otherwise, how useful is SSH, anyway? ;-)
