Nou, ik heb uiteindelijk die wireless usb adapter (in China!) besteld en na 14 dagen gekregen. Maar out-of-the-box werken, ho maar! Maar ik krijg de indruk dat het toch wel moet kunnen werken, er zit een linux-map bij...
In de linuxmap zit een Readme file en daarin staat:
Release Date: 2006-02-09, ver 1.2
RTL8187 Linux driver version 1.2
--This driver supports RealTek RTL8187 Wireless LAN driver for
Fedora Core 2/3/4/5, Debian 3.1, Mandrake 10.2/Mandriva 2006,
SUSE 9.3/10.1/10.2, Gentoo 3.1, etc.
- Support Client mode for either infrastructure or adhoc mode
- Support WEP and WPAPSK connection
< Component >
The driver is composed of several parts:
1. Module source code
stack.tar.gz
drv.tar.gz
2. Script ot build the modules
makedrv
3. Script to load/unload modules
wlan0up
wlan0down
4. Script and configuration for DHCP
wlan0dhcp
ifcfg-wlan0
4. Supplicant source code:
wpa_supplicant-0.4.9.tar.gz
5. Example of supplicant configuration file:
wpa1.conf
< Installation >
Runing the scripts can finish all operations of building up modules
from the source code and start the nic.
1. Build up the drivers from the source code
./makedrv
2. load the driver module to kernel and start up nic
./wlan0up
< Set wireless lan MIBs >
This driver uses Wireless Extension as an interface allowing you to set
Wireless LAN specific parameters.
Current driver supports "iwlist" to show the device status of nic
iwlist wlan0 [parameters]
where
parameter explaination [parameters]
----------------------- -------------
Show available chan and freq freq / channel
Show and Scan BSS and IBSS scan[ning]
Show supported bit-rate rate / bit[rate]
Show Power Management mode power
For example:
iwlist wlan0 channel
iwlist wlan0 scan
iwlist wlan0 rate
iwlist wlan0 power
Driver also supports "iwconfig", manipulate driver private ioctls, to set
MIBs.
iwconfig wlan0 [parameters] [val]
where
parameter explaination [parameters] [val] constraints
----------------------- ------------- ------------------
Connect to AP by address ap [mac_addr]
Set the essid, join (I)BSS essid [essid]
Set operation mode mode {Managed|Ad-hoc}
Set keys and security mode key/enc[ryption] {N|open|restricted|off}
For example:
iwconfig wlan0 ap XX:XX:XX:XX:XX:XX
iwconfig wlan0 essid "ap_name"
iwconfig wlan0 mode Ad-hoc
iwconfig wlan0 mode essid "name" mode Ad-hoc
iwconfig wlan0 key 0123456789 [2] open
iwconfig wlan0 key off
iwconfig wlan0 key restricted [3] 0123456789
< Getting IP address >
After start up the nic, the network needs to obtain an IP address before
transmit/receive data.
This can be done by setting the static IP via "ifconfig wlan0 IP_ADDRESS"
command, or using DHCP.
If using DHCP, setting steps is as below:
(1)connect to an AP via "iwconfig" settings
iwconfig wlan0 essid [name] or
iwconfig wlan0 ap XX:XX:XX:XX:XX:XX
(2)run the script which run the dhclient
./wlan0dhcp
or
dhcpcd wlan0
(Some network admins require that you use the
hostname and domainname provided by the DHCP server.
In that case, use
dhcpcd -HD wlan0)
< WPAPSK >
WPA_SUPPLICANT help the network to communicate under the protection of WPAPSK
mechanism
(1)Unpack source code of WPA supplicant:
tar -zxvf wpa_supplicant-0.4.9.tar.gz
cd wpa_supplicant-0.4.9
(2)Create .config file:
cp defconfig .config
(3)Edit .config file, uncomment the following line:
#CONFIG_DRIVER_IPW=y.
(4)Build WPA supplicant:
make
If make error for lack of <include/md5.h>, install the openssl lib(two ways):
1. Install the openssl lib from corresponding installation disc:
Fedora Core 2/3/4/5(openssl-0.9.71x-xx), Mandrake10.2/Mandriva10.2(openssl-0.9.7x-xmdk),
Debian 3.1(libssl-dev), Suse 9.3/10.0/10.1(openssl_devl), Gentoo(dev-libs/openssl), etc.
2. Download the openssl open source package from
www.openssl.org, build and install it.
(5)Edit wpa_supplicant.conf to set up SSID and its passphrase.
For example, the following setting in "wpa1.conf" means SSID
to join is "BufAG54_Ch6" and its passphrase is "87654321".
network={
ssid="BufAG54_Ch6"
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP WEP104 WEP40
psk="87654321"
priority=2
}
(6)Execute WPA supplicant (Assume 8187 and related modules had been
loaded):
./wpa_supplicant -D ipw -c wpa1.conf -i wlan0 &
Kan iemand me in mensentaal uitleggen hoe ik de boel moet installeren? Dat is het grote probleem met linux cq. ubuntu, het veronderstelt een heleboel kennis van de werking, maar een relatieve leek zoals ik heeft geen idee hoe hij de.e.a. moet aanpakken.
Anders zit ik nu met m'n derde usb-stick... :-(
Alvast bedankt,
Rob
