Summary + +This document describes a little more of the detail behind configuring the +linux-wlan system. + +2. Installed Componenents + +The linux-wlan-ng package consists of the following components: + + p80211.o Kernel module for 802.11 services + prism2sta_cs.o Kernel module for the Prism2 PCMCIA device + driver. + wlanctl-ng User-mode utility for sending commands to + 802.11 services and MAC-specific drivers. + wland User-mode daemon for receiving and handling + events from 802.11 services and MAC-specific + drivers (not used in this version). + /etc/pcmcia/wlan-ng* PCMCIA event and configuration scripts + + *prism2dl This utility is used for loading firmware + images into prism2 cards. DO NOT USE IT! + UNLESS YOU KNOW EXACTLY WHAT YOU ARE DOING. + This utility has the capability to damage a + card in a way that can only be repaired by the + manufacturer. + +When a 'make install' is performed, the modules are copied to the +/usr/lib/modules/<kernelver>/net and /usr/lib/modules/pcmcia directory, +the user-mode utilities are copied to /sbin, and the contents of +linux-wlan-ng/etc/pcmcia are copied to the /etc/pcmcia directory. If +necessary, the pcmcia config files are altered to include a reference to +the wlan-ng.conf file containing the information cardmgr uses to match +card CIS information to specific device drivers at card insertion time. + +NOTE: It is very important that you restart your pcmcia services after +installing linux-wlan-ng. cardmgr will not recognize the information +in the wlan-ng.conf file until after it has been restarted. + + +3. Configuration Variables + +To configure your installation for use, it will probably be necessary +to edit the /etc/pcmcia/wlan-ng.opts file. This file contains a +collection of variable assignments that are used by the wlan-ng script +to intialize your card at insertion time. The variables are broken +into groups: ENABLE, DOWNLOAD, USER MIB, WEP, STA, and AP START. + +Many of the choices involved in choosing configuration variable +settings are dependent on whether you are setting up your system as a +Station (STA) or an Access Point (AP). STA configuration is most +common. If you are using a mobile station that will connect to one or +more APs, STA configuration is all you will need. + +3.1 ENABLE Group +The only variable is this group is: + +WLAN_ENABLE=y + This variable determines whether the card will be intialized, + configured for operation, and your protocol stack configured. + Generally, you always want this set to 'y'. For some cards, + you will set this variable to 'n' when performing card + maintenance like firmware upgrades. + +3.2 DOWNLOAD Group + +The DOWNLOAD group contains variables that indicate if code or data +needs to be downloaded to the card prior to initialization and normal +operation. Currently, this is only required for the Prism2 card when +running in AP mode. + +WLAN_DOWNLOAD=n + Set this variable to 'y' if code or data must be downloaded + into the card prior to operation. + +WLAN_DOWNLOADER=/sbin/prism2dl + This variable contains the name of the program used to + download the code into the card. + +WLAN_DLIMAGE=/etc/wlan/apfw.hex + This variable contains the name of the file you wish to + download. + +3.3 USER MIB Group + +There is only one variable in this group, USER_MIBS. You may add your +own local MIB item assignments assignments to this variable. The +wlan-ng script will loop through the assignments found in this +variable and configure the card with each one prior to final +configuration and enable. + +3.4 WEP Group + +The variables in the WEP group are used to configure the 802.11 "Wired +Equivalent Privacy" element of the MAC if it is supported. The driver +is queried for WEP support prior to attempting WEP configuration. If +the driver states that WEP is NOT supported, these variables are +ignored. Note that you may need to set some of these variables even if +you are not using the privacy service. If shared-key authentication +is used, the WEP keys must be present. + +dot11PrivacyInvoked=false + Set this variable to "true" to enable the WEP support. + +lnxreq_hostWEPEncrypt=false +lnxreq_hostWEPDecrypt=false + Set these to true if you want WEP to be handled by the driver + instead of the hardware. The only downside of this is that it + takes a bit of CPU time and you lose the ability to handle + fragmentation. However, with prism2 cards, you should see a + performance boost, and with prism2.5 cards, this may avoid lockups. + +dot11WEPDefaultKeyID=1 + This variable identifies which of the WEP keys is the default + key used for all transmits from this station. In some + implementations, this can be changed (or rotated) later. + +dot11ExcludeUnencrypted=true + Setting this variable to "true" and dot11PrivacyInvoked to + true, has the effect of making WEP completely required for this + station (or AP). If set to "true", this STA will discard any + received frames that are not encrypted. + +PRIV_GENERATOR=/sbin/nwepgen + Some vendors include "WEP Key Generator" programs as part of + their windows or AP implementations. This is purely a + convenience to prevent you from having to type in 40 + hexadecimal digits. It does not contribute to the secrity of + your system at all. In some cases, we've included small + programs that generate keys in a manner compatible with the + vendor's method. If you wish to use this capability, include + the name of the generator program here. + +PRIV_GENSTR="12345" + Every generator implementation we've seen so far uses some + kind of 'passphrase' to generate the keys. This variable + contains the passphrase. To disable the use of a generator, + leave this variable empty. + +dot11WEPDefaultKey0 +dot11WEPDefaultKey1 +dot11WEPDefaultKey2 +dot11WEPDefaultKey3 + If you are configuring your keys by hand, you need to assign + these four variables. The format is "xx:xx:xx:xx:xx" and the + order of the keys in these variables IS IMPORTANT. Note: If + the PRIV_GENSTR variable is not empty, these variables are + ignored. + +3.5 STA Group + +Currently, there is only one variable in the STA group. This will +change over time. + +dot11DesiredSSID="WLAN_PRISM2" + This variable contains the SSID or "network name" of the + wireless network you wish to associate with. + +3.6 AP START Group + +If you have access to the necessary hardware and firmware, this driver +can be used to set up a Access Point. To configure for an access +point, set the IS_AP variable to 'y'. The following is a quick +summary of the other AP configuration variables: + + +APBRIDGEDEVICE=eth0 + Defines the ethernet device that will be the 'other' port for + bridging 802.11 frames. +APSSID="WLAN_PRISM2" + Defines the SSID that the AP will use when creating the network. +APBCNINT=100 + Defines the beacon interval (in Kus) that the AP will use. +APDTIMINT=3 + Defines the DTIM interval (in beacon intervals). + +APCFPOLLABLE|APCFPOLLREQ | Description +--------------------------- + false | false | No point coordination by this AP + false | true | AP will point coordinate for delivery only + true | false | AP will point coordinate for deliver and polling + true | true | Reserved + +APCFPPERIOD=3 + Defines how often the contention free period occurrs (in + beacons). + +APCFPMAXDURATION=100 + Defines the maximum length of the contention free period (in + Kus). + +APPROBEDELAY=100 + Not used for infrastructure networks, any value is valid. + +APCHANNEL=6 + Channel that the AP will create the network on. Range of valid + values depends on you regulatory domain. In the USA and Canada + the range is 1-11. In Japan the range is 1-14. + + +APBASICRATES="2 4" + A whitespace separated list of data rates in units of 500Kb/s. + The basic rate set is the set of rates that stations MUST + support to be allowed to join the network. + +APOPRATES="2 4 11 22" + A whitespace separated list of data rates in units of 500Kb/s. + The operational rate set is the set of rates that are allowed + in the network. It must be a superset of the basic rates + above. + +To complete the configuration of an Access Point, you will need to +make sure you have kernel bridging enable in your currently running +kernel and have the brcfg utility installed. One version of the brcfg +utility can be found at ftp://ftp.absoval.com + +To start the access point running, make sure the ethernet card is in the +system first. Then insert the WLAN card and everything should be +configured automatically by the /etc/pcmcia/wlan-ng script. + + |
