Do I need to reinstall?

[Mark Fraser]

I've got the feeling that something on my install isn't quite right. I
tried to install ndiswrapper which went ok, but when I tried to follow the
instructions some things weren't quite as they should be.

First of all where as I'm told I should be able to type just ndiswrapper
into a console window, I have to type /usr/sbin/ndiswrapper same goes for
iwconfig for which I have to type /sbin/iwconfig and I still can't seem to
do a scan.

If a reinstall isn't required is there something I can do to check my
install out to see what is wrong?

Type this:

su -

And then try your commands.

Explanation: "su" by itself gives you the UID and GID of root.  "su -"
(with the dash) gives you the UID and GID of root AND root's environment
(environment variables, path, etc.).  Essentially the dash says "do a
full login of me as root".

Thanks for that. I did manage to get ndiswrapper working for a while, but
then the whole computer locked up. This looks like it is due to the
difference in stack sizes between the kernel and the driver I am trying to
use. From what I have read, this requires recompiling the kernel to use a
8KB stack which is beyond me at the moment.

Actually, its not really as hard as you might imagine. There are several web 
pages explaining the steps.

In the past I have followed the steps here

http://www.city-fan.org/tips/TweakKernelPackage

Which allow you to create fedora kernels rpms, with whatever tweaks you want. 
For you, you will need to at the  "Reconfigure the kernel" step find the 
option to enable 8k stacks (I recommend the xmenu over the menuconfig )

Alternatively, there are rpms out there in google-land you can find with 8k 
stacks. I happen to know that linuxant (which provides a commercial product 
called driverloader which performs the same thing as ndiswrapper ) provides 
FC kernel rpms with larger stack sizes. See here

http://www.linuxant.com/driverloader/wlan/full/downloads.php

and follow the link for your FC version and system arch.

( btw. driverLoader is very good - I was forced to use it for a while when 
ipw2100 did not exist and ndiswrapper caused my machine to hang hard ! 
DriverLoader worked a treat )

cheers Chris

Most likely you are typing those commands as a regular user instead of 
root.  typing 'su -' (without quotes) on the command line will get you 
to the root user which will allow you to setup your wireless.

That happens to me also - not w/ those particular progs but anything
in /usr/sbin and /sbin I have to specify the path and yes I am su'd as
root.  I figured it was something i screwed in my .profile and haven't
bothered to spend the time to figure it out.

Just put a dash after the su and you will be all set.

su -
commands go here

[Bazooka Joe]

Wow, what a difference a dash makes - do you know how long I have been
typing paths and just excepted it.

Thx - this makes my week

The difference is this: "su" simply makes your UID be 0. "su -"
makes it look like you logged in as root, so it runs the root
setup.

BTW...if you edit your .bash_profile file, and add /usr/sbin and /sbin to
your PATH statement, you should be all set the next time you log in.

Please note that 'su root' is NOT the same as 'su - root'.  In the 
first case it will retain YOUR defined path, whereas the second one will 
switch to root's path.

su root:

[6] 12:55:07 <kirash@ivanhoe:~> echo $PATH
/bin:/usr/bin:/usr/local/bin:/usr/bin/X11:/usr/X11R6/bin:/home/kirash/bin

[7] 12:55:10 <kirash@ivanhoe:~> su root
Password:
[1] 12:55:17 <root@ivanhoe:/home/kirash> echo $PATH
/bin:/usr/bin:/usr/local/bin:/usr/bin/X11:/usr/X11R6/bin:/home/kirash/bin

Now the other one: su - root

[8] 12:55:59 <kirash@ivanhoe:~> echo $PATH
/bin:/usr/bin:/usr/local/bin:/usr/bin/X11:/usr/X11R6/bin:/home/kirash/bin

[9] 12:56:02 <kirash@ivanhoe:~> su - root
Password:
[1] 12:56:05 <root@ivanhoe:~> echo $PATH
/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/bin/X11:/usr/X11R6/bin:/root/bin
