SYNOPSIS
cnwctl |
[-d
domain]
[-i
interface]
[-k
scramble-key]
[-sS
[rate]] |
DESCRIPTION
The
cnwctl utility is used to control Netwave AirSurfer PC
Cards as well as display statistics. The following options are available:
-
-
- -d
- Set the domain of the card to domain.
The domain must be between 0x000 and 0x1ff. The domains 0x000 through
0x0ff are for access to an add-hoc network. The domains 0x100 through
0x1ff are for access to a Netwave Access Point. The default domain is
0x000. A card may only talk to the access point in its domain, or other
cards in its add-hoc domain.
-
-
- -i
- Use interface as the interface rather
than
cnw0
.
-
-
- -k
- Set the scramble key to scramble-key.
The scramble key must be between 0x0000 and 0xffff. Both the source and
the destination must use the same scramble key in order to
communicate.
-
-
- -s
- Display statistics. When the optional argument
rate (which must be the last argument to the end of
the command line) is specified as a non-zero value, statistics will be
displayed every rate seconds. At the top of each
“page” of statistics, column labels will be displayed. The
first row of statistics will be totals since boot, subsequent lines are
deltas from the previous row. If rate is not
specified, or is 0 (zero), a single page of statistics will be displayed.
