Network information can be found in the Ethernet-HOWTO,
Networking-Overview, NET3-4, IP-Masquerade. Before you can share
an internet connection, be sure that your ordinary network works. This is
how it works in a few words:
Machine A:
- modprobe ne (replace ne with your network card driver)
- ifconfig eth0 192.168.1.1 netmask 255.255.255.0 up
Machine B:
- modprobe ne (replace ne with your network card driver)
- ifconfig eth0 192.168.1.2 netmask 255.255.255.0 up
etc. This is for all machines the same, only the IP addresses are
different. You can check if this works by pinging other hosts:
from A: ping 192.168.1.2
from B: ping 192.168.1.1
To share one internet connection, you need to set up a computer as a
gateway. Then configure for machines B, C, etc. A as gateway with:
- route add default gw 192.168.1.1
Then, on machine A do (if you have a 2.2 kernel):
ipchains -F forward
ipchains -P forward DENY
ipchains -A forward -s 192.168.1.0/255.255.255.0 -d 0.0.0.0/0.0.0.0 -j MASQ
ipchains -M -S 3600 0 0
echo 1 > /proc/sys/net/ipv4/ip_forward
This should work. Information about this can be found in various HOWTO's.

Practically the same way. Make sure that windoze has detected your
ethernet card. Then configure the network settings, select the properties
of TCP/IP->networkcard (or something alike) and fill in the
desired IP-adress, netmask and gateway and some nameservers (if you do not
know them, do a 'type /etc/resolv.conf' on your gateway machine). If win9x
reboot and wait forever, if win2k it will work right away.
