How to share eth0 > wlan0 Internet? Ad-Hoc.

[Alexey]

Previously, I was able to set up wi-fi card (iwconfig), dhcp server and iptables.

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

How do correctly configure wi-fi card and a dhcp server?

Code:

krab@note ~ $ ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:26:2D:AC:B9:E2 
          inet addr:192.168.1.3  Bcast:192.168.1.255  Mask:255.255.255.0

Okey!

Code:

$ nano /etc/default/dhcp
INTERFACES="eth0"
$ nano /etc/default/dhcpd
INTERFACES="eth0"

Code:

$ nano /etc/dhcp/dhcpd.conf
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.2.255;
option routers 192.168.2.1;
option domain-name-servers 192.168.1.1;

subnet 192.168.2.0 netmask 255.255.255.0 {
interface wlan0;
range 192.168.2.2 192.168.2.20;
}

Code:

iwconfig wlan0 mode ad-hoc
iwconfig wlan0 channel 1
iwconfig wlan0 Bit 54Mb/s
iwconfig wlan0 essid "linux"
ifconfig wlan0 192.168.2.1 netmask 255.255.255.0 up

Code:

sudo service dhcpd restart

What do I get?

Internet from my ADSL router (configured as DHCP) > notebook (eth0) > wi-fi AD-HOC (wlan0) > Galaxy TAB!
