I bought a wireless PCI card for my Slackware 10.1 router/server without
doing some advance research. I was hoping to use the wireless card to allow the
router/server to do NAT for both wired connection and wireless
connections. This is essentially to allow my laptop and my neighbour to
get acces to the LAN and the internet without having to plug wires in.

Currently I have the two NIC thing with DHCP on the computer and it works
well. I share files via NFS for Linux users and samba for Windows users.
Essentially, I would like to add a wireless compent to the setup.

Is there a Howto out there? Can my DHCP server issue IPs on two NICs?

THanks in advance

Jenn

I can't help you with the wifi stuff, but I can tell you that yes,
dhcpd can hand out IPs on an arbitrary number of NICs. The easiest way
to do this is to have the two NICs on different subnets.

eth0 192.168.1.1
eth1 192.168.2.1

You can setup /etc/dhcpd.conf to hand out IPs freely. Slackware doesn't
include a rc.dhcpd startup script, so I'm enclosing mine on the off
chance it will help you.

You'll have to edit rc.M and rc.0 to start and stop it on boot if you
want it to all go smoothly, otherwise you can just referance this in
rc.local.

/etc/rc.d/rc.dhcpd
#!/bin/bash
# Start, stop, and restart the DHCP server.

dhcpd_start() {
echo "Starting the dhcp server."
if [ -x /usr/sbin/dhcpd ];then
/usr/sbin/dhcpd
fi
}

dhcpd_stop() {
echo "Stopping the dhcp server."
/bin/kill $(/bin/cat /var/run/dhcpd.pid)
}

dhcpd_restart() {
echo "Restarting the dhcp server."
dhcpd_stop
dhcpd_start
}

# See how we are called.

case "$1" in
'start')
dhcpd_start
;;
'stop')
dhcpd_stop
;;
'restart')
dhcpd_restart
;;
*)
echo "Usage $0 start|stop|restart."

Before you go any further you should search the net to see if this card
can operate in "Master" mode. Only cards that support the master mode
can be used in a router setup like this, and many cards only supports
"Managed" or "Ad-Hoc" modes.

A lot depends on what chipset your wireless card has and if there is a
linux driver for it. 'lspci' and 'lspci -n' will help with that.

Things are pretty untidy in the Linux wireless world, but here is a good
start
