WEP Not Working

[lfirth]

Hi, I eventualy have managed to get my wireless network card up and running with Fedora Core 4, I thought that it was abaout time I added a little security to it so have attempted to add WEP. The following is the output of my /etc/sysconfig/network-scripts/keys-wlan0 file

KEY=s:d472979ddb

I read on another forum that it may be necessery to ad the 's:' to get it to work properly but either way with or without the 's:', this will not allow me to connect to the wirlwess AP.

Any suggestions as to why or as to what else I can try?

taken from the iwconfig man page:

key/enc[ryption]
Used to manipulate encryption or scrambling keys and security mode.
To set the current encryption key, just enter the key in hex digits as XXXX-XXXX-XXXX-XXXX or XXXXXXXX. To set a key other than the current key,
prepend or append [index] to the key itself (this won’t change which is the active key). You can also enter the key as an ASCII string by using
the s: prefix. Passphrase is currently not supported.
To change which key is the currently active key, just enter [index] (without entering any key value).
off and on disable and reenable encryption.
The security mode may be open or restricted, and its meaning depends on the card used. With most cards, in open mode no authentication is used and
the card may also accept non-encrypted sessions, whereas in restricted mode only encrypted sessions are accepted and the card will use authentica-
tion if available.
If you need to set multiple keys, or set a key and change the active key, you need to use multiple key directives. Arguments can be put in any
order, the last one will take precedence.
Examples :
iwconfig eth0 key 0123-4567-89
iwconfig eth0 key [3] 0123-4567-89
iwconfig eth0 key s:password [2]
iwconfig eth0 key [2]
iwconfig eth0 key open
iwconfig eth0 key off
iwconfig eth0 key restricted [3] 0123456789
iwconfig eth0 key 01-23 key 45-67 [4] key [4]


it depends on how you setup your wep key. one of those will work using your interface name...eth1, ath0, wlan0, etc...

Couldn't run the command cos I got the following error.

[root@localhost sbin]# iwconfig wlan0 key d472-979d-db
bash: iwconfig: command not found
[root@localhost sbin]#

dir shows that the command is there:

when you su to root use su - (yes with the dash) so its sets up path's for the root user.

or use /usr/sbin/iwconfig everytime

Thanks for your help, but I tried all the options available in both ASCII and HEX and it just won't connect. I'll just have to leave it open.

Replace the "s" with an "o"
KEY=s:d472979ddb becomes KEY=o:d472979ddb

Security mode must be open and not shared. I read this somewhere from the ipw2100 website at sourceforge.

What I noticed was that the keys in /etc/sysconfig/network-scripts/keys-XXX is not getting configured. You can verify this if you do a iwconfig wla0 and check the encryption if it is the same key you are using.

sample iwconfig output below:
eth1 IEEE 802.11b ESSID:"MyAP" Nickname:"MyPC"
Mode:Managed Frequency:2.432 GHz Access Point: XX:XX:XX:XX:XX:XX
Bit Rate=11 Mb/s Tx-Power:off
Retry min limit:7 RTS thr:off Fragment thr:off
Encryption key:1111-2222-3333-4444-5555-6666-772 Security mode:open
Power Management:off
Link Quality=100/100 Signal level=-36 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:251 Missed beacon:0

Hope it helps you as that is how I solved my problem.

THAT'S IT!

Works now, thank you for the tip.
