Wandering around in the /etc/sysconfig tree, I find that there seem to

No damned wonder I can edit the /etc/sysconfig/network-scripts version
of ifcfg-wlan0, restart that interface and then see that iwconfig nor
ifconfig appear to reflect the changes I've made.

So which is the master version of these files, and how many of the
friggin dupes can I actually nuke to get rid of the effect of trying to
make a change and having that change ignored?

Right now there are:
root diablo sysconfig]# ls -lL `locate ifcfg-wlan0`
-rw-r--r-- 3 root root 314 May 10 21:21
/etc/sysconfig/networking/devices/ifcfg-wlan0
-rw-r--r-- 3 root root 314 May 10 21:21
/etc/sysconfig/networking/profiles/default/ifcfg-wlan0
-rw-r--r-- 3 root root 314 May 10 21:21
/etc/sysconfig/network-scripts/ifcfg-wlan0

Can anyone explain just what the heck is going on here?  This is driving
me to drink, which I don't mind all that much within limits (2 beers,
I'm diabetic), but its making me buy the gas too!


2 words "Hard Link".

Do an "ls -i" on the files and you will see they all have the same inode.

Which says that I should be able to edit any one of them and have that change be taken globally. In which case, note this ESSID setting:
[root diablo etc]# cat `locate ifcfg-wlan0` |grep ESSID
ESSID=MountainHost
ESSID=MountainHost
ESSID=MountainHost

Which s/b fine BUT:

[root diablo etc]# iwconfig wlan0

Kwifimanager can also find the access point by its ESSID, but as you can see the key is on and wep, supposed to be off/open.

[root diablo etc]# cat `locate ifcfg-wlan0` |grep KEY
KEY=open
KEY=open
KEY=open

and an iwlist wlan0 scan shows this:
[root diablo etc]# iwlist wlan0 scan

                   Extra:atim=0

for the two access points located in this motel building. There is no possibility of a connection until I can convince wlan0 that the fscking key is off or open. That SEEMS like the next step in this little dance unless someone more experienced than I can see something else wrong above.
