Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hi. Hoping someone can tell me what I'm missing with my wireless setup.
Running slack12, 126.96.36.199 on a toshiba laptop with an ipw3945 card. Dual boot with winXP.
Previously had wireless working with Vector 5.8. Recently installed slack12 and have not been able to get wireless working.
Recently wireless stopped working under windows with similar symptoms (could see wireless network and network settings all seemed OK) and this was fixed by uninstalling and reinstalling driver. I'd put this down to normal windows behaviour.
I've built the driver module under this kernel (from source, not the slackware extras package) and it gets loaded in /etc/rc.d/rc.modules
The ipw3945d daemon gets started in rc.local
So far I think it's all OK because e.g.
# iwlist scanning
produces a normal output including my own wireless network.
iwconfig output looks ok to my newbie eye
lo no wireless extensions.
eth0 no wireless extensions.

The wireless device was always eth1 (192.168.1.3). The wired NIC is eth0 which is working fine (192.168.1.2).
The changes I've made are:
/etc/modprobe.d/wireless:alias eth1 ipw3945
Settings for eth1 in /etc/rc.d/rc.inet1.conf

With all of this can't ping my wireless router except with a wired connection (Destination host unreachable) or connect anywhere else
Didn't want to make this too much bulkier. If someone is able to help please just let me know which other outputs I should include. And I'm sure my problem has been dealt with before but I jst can't find a thread which quite matches my problem.
Thanks for reply. I never bothered about it before, both were always up without a problem. I have got wireless working in my Vector linux installation and for some reason now it did only work after
# ifconfig eth0 down
but this has not fixed the problem in slack12.
I thought it could be because eth0 was listed at the end of the default route line, so I did
# route del default
# route add default gw 192.168.1.1 eth1
but still no dice
At least I know it's not a hardware problem.
Thanks for the suggestion - keep 'em coming!
Decided to start with a clean slate. Went right through /etc/rc.d commenting out every mention of eth0 or eth1, all wireless settings (except for loading the driver and the daemon) and rebooted. After
# ifconfig eth1 192.168.1.3 netmask 255.255.255.0
# route add default gw 192.168.1.1
# iwconfig eth1 essid "MyNetwork"
# iwconfig eth1 key XXXXXXXXXXXXXXXX
everything works. Only problem is everything I commented out looked like it belonged there,so I'm a bit confused about the boot scripts.
I'll just make this a script for the moment but if anyone wants to tell me how all these things should really be started I'd be very grateful.
