Seems to work ok with kernel 2.0.30 and redhat 4.1

INSTALLATION

This card is configured the same as pretty much any other Ethernet
card. You need to set up one gateway or bridge PC that links the radio
segment of the Ethernet to the normal portion of the Ethernet.

This assumes that the radio modems are being set up on a class C subnet of
192.168.1.0.

Compile the driver on both machines with

	gcc -O -c arlan.c

Install the driver on both machines with

	insmod arlan.o irq=5

for the host PC setup the card's IP with

	ifconfig arlan0 192.168.1.254

or for the robot with

	ifconfig arlan0 192.168.1.1

on the host PC add a route with 

	route add -net 192.168.1.0 netmask 255.255.255.0 dev arlan0

on the robot add a route with a gateway with

	route add default gw 192.168.1.254 dev arlan0

on other workstation on the wire based Ethernet add routes to the gateway
host PC with

	route add -net 192.168.1.0 gw 100.100.3.4 netmask 255.255.255.0

where 100.100.3.4 is replaced with the IP addr of the PC that does the gateway

Additional robots would be the same except the 192.168.1.1 would change to 
something like 192.168.1.2 for the second robot etc. It' really all the same
as  

Test with pings both directions

you can install the driver with

	insmod arlan.o debug=2

to get more info about when packets are sent or received. debug=100 produce
lots of printouts

If you have problems, send me the results of doing a 

	ifconfig 

on both machines as well as

	cat /proc/net/arp
	route



If you are running redhat - you might try "make install" then run the
control-panel. From there go to the runlevel editor and add starting arlan
to level 3 and make sure it is before networking (I used priority 05). Now
go to the network-config tool and set the ip, gateway, and routes as
described above.


Good luck
