ray_cs4

Usage

Overview

ray_cs is the low level Card Services device driver for the Raylink wireless LAN PCMCIA adapter. It is normally loaded automatically by card services according to the parameters specified in /etc/pcmcia/ray_cs.opts.

Parameters

essid=string

ESS ID - network name to join string with maximum length of 32 chars default value = "LINUX"

irq_mask=n

linux standard 16 bit value 1bit/IRQ lsb is IRQ 0, bit 1 is IRQ 1 etc. Used to restrict choice of IRQ's to use.

net_type=n

0 = adhoc network (default) 1 = infrastructure

ray_debug=n

(0-5) larger values for more verbose logging.

phy_addr=string

string of 12 hex digits containing new MAC address. must be started with x e.g. x00008f123456

hop_dwell=n

hop dwell time in Kilo-microseconds legal values = 16,32,64,128(default),256

beacon_period=n

Beacon period in Kilo-microseconds.
Legal values = 16,32,64,128,256(default) must be integer multiple of hop dwell.

psm=n

Power save mode
0 = continuously active
1 = power save mode (significantly slower)

bc=n

Power save mode
0 = 802.11 timing
1 = 802.11 modified timing. Interframe spacing is slowed down for compatibility with older Breezecom access points.

translate

0 = no translation (encapsulate frames)
1 = translation (default)

country=n

Country code
1 = USA (default)
2 = Europe
3 = Japan
4 = Korea
5 = Spain
6 = France
7 = Israel
8 = Australia

sniffer=n

0 = normal network interface - not sniffer (default)
1 = sniffer which can be used to record all network traffic using tcpdump or similar, but no normal network use is allowed. This is because linux has no knowledge of 802.11 headers and cannot parse them correctly. Note that tcpdump does not understand 802.11 headers, either so it can't interpret the contents, but it can record to a file.

ray_cs can lock the machine if the card is pulled out while active.
