You might connect your Linux box using IrLAN to another network
device such as a Linux box with IrLAN, a HP NetBeamer or a
Window$95 box with Infrared Network Device support.

Maybe you have to choose the access mode. You can do this by using
modprobe irlan access=1 for direct mode. IrLAN states that a
provider can either be in direct mode, or in peer mode, so you
currently have to choose when you start IrLAN.
Run ifconfig eth0 up <ip_address> netmask <ip_netmask> to
configure it with IP-address and other parameters. If the protocol
is still running you may start communicating. It is possible to
use RedHat's netcfg to do this, since it makes it very easy. Next
time you only need to do /sbin/ifup eth0. Notice that ifconfig
does not know how to deal with IrLAP addresses, so the address is
really just the 4 first bytes (in little endian format).
Test the network device by pinging to it. For detailed information
about further setup see the NET3-HOWTO.
Do not forget to add a route, e.g. route add default gw
<ip_gateway> or route add -host <target host> dev eth0.
Ping to another IP now, to test the connection.
For testing reasons I recommend only to use one laptop and one IR
ethernet device in the same room. If there are problems look which
different modes for the IR ethernet device are possible. Try them.
