HOWTO: Madwifi Accesspoint edgy
Hi All,
Want set up an AP for your home WIFI network? Got an Atheros chipset Wireless Card? Got a Fresh install of edgy?
Yes!!!!!
Good then read on and you'll make an access point out of it in a few minutes
-This howto is my first ever so please be kind - I only want to give back to the ubuntu commnity
Coming straight after a fresh load from an edgy 6.10 install CD
also for the very very green - commands are italicized so just copy and paste them
open a terminal
1st : sudo apt-get update
2nd : sudo apt-get dist-upgrade
(I can't get the AP up properly unless I do an upgrade first so I recomend you do too)
3rd : Reboot
4th : sudo apt-get install build-essential
5th : download the current snapshot from here http://snapshots.madwifi.org/dadwifi-current.tar.gz
6th : extract the file to a folder mine is on the desktop so from your home folder cd Desktop then cd to the madwifi folder
7th : make clean
8th : make
9th : make install
10th : choose remove the current module from the system and you have the driver installed good for you!!!!!!
11th : sudo modprobe ath_pci autocreate=ap
12th : sudo gedit /etc/modules
13th type in ath_pci autocreate=ap then save it
14th sudo gedit /etc/modprobe.d/madwifi
15th type options ath_pci autocreate=ap then save and close
16th sudo gedit /etc/network/interfaces
17th auto ath0
iface ath0 inet static
address 192.168.3.5
netmask 255.255.255.0
broadcast 192.168.3.255
[wireless-essid WiFiAp
wireless mode master Just change this to suite your network ip addresses
18th setup routing of some sort I use this script for my home network and placed it in
/etc/network/if-up.d (I got the script from www.debianadministrator - simple debian gateway) I name it 00firewall and made it executable and then reboot
#!/bin/sh
PATH=/usr/sbin:/sbin:/bin:/usr/bin
#
# delete all existing rules.
#
iptables -F
iptables -t nat -F
iptables -t mangle -F
iptables -X
# Always accept loopback traffic
iptables -A INPUT -i lo -j ACCEPT
# Allow established connections, and those not coming from the outside
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -m state --state NEW -i ! eth1 -j ACCEPT
iptables -A FORWARD -i eth1 -o eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
# Allow outgoing connections from the LAN side.
iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT
# Masquerade.
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
# Don't forward from the outside to the inside.
iptables -A FORWARD -i eth1 -o eth1 -j REJECT
# Enable routing.
echo 1 > /proc/sys/net/ipv4/ip_forward
19th on a client machine
iface rausb0 inet static
address 192.168.3.5
netmask 255.255.255.0
broadcast 192.168.3.255
[wireless-essid WiFiAp
20th on the client machine you'll need to setup your isp's DNS settings in the networking panel (can't think of the file right now) because this is a static address setup... Either that or setup a DNS server like bind9 on you AP thats what I did
ping the machine and boingo you should be done
I hope this helps
Please feel free to make suggesstions or even corrections and as for credits???? well I credit myself for doing heaps of reading and re-installing about 10-15 times
And I credit fairly crappy explanations or complete howto's to the need for writing this one and ironically just as I got to the end of my search for knowledge I found in the forums the very same conlcusion that i came to by doing a search for
yep you guessed it ath_pci autocreate=ap
It confirmed what I was just about to do so I'm glad the thread was there but it was very obscure.
Cheers All Again I hope this helps
