need help with lan

hey there,

ok, i have Arch connected to the net via cable modem and eth0. i also have a laptop that i want to connect to the net thru this computer. It runs windows2000 and i have been searching forums for a while now and i need some more help.

i have two ethernet cards in this computer. My ifconfig reads
eth0 Link encap:Ethernet HWaddr 00:50:BF:93:D0:81
inet addr:69.92.12.105 Bcast:255.255.255.255 Mask:255.255.255.0

RX bytes:3600 (3.5 Kb) TX bytes:3600 (3.5 Kb)

and my rc.conf reads

lo="lo 127.0.0.1"
eth0="dhcp"
eth1="eth1 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255"

INTERFACES=(lo eth0 eth1)

gateway="default gw 192.168.0.1"
ROUTES=(!gateway)

i want to be able to do file share, internet share and such but cant seem to get this hooked up right. i am using a crossover cable from eth1 on this box to the ethernet card on the laptop.

i am stumped, i installed iptables, but dont know what to do with it. i am not interested in a firewall right now, maybe later. i just want to get this stuff hooked up.

any pointers? thanks much

First you need to setup you Winbox with a 192.168.1.2 ip address. Then setup routing gateway 192.168.1.1. Second, test to see if can you ping you Win box from you linux box? and reverse linux box to Win box? ie: from your win box ping 192.168.1.1 then from you linux box ping 192.168.1.2
I changes on the win box may take a while to activate?
If the above works try accessing a site on the internet from you win box and linux box. Then you can use some wiki doc or man doc to setup samba for file sharing, as I have not used windows for a few years I am not sure how?

I use firestarter for configuring my firewall.

ok, cant ping from linux ( the router ) dont know how to try from windows 2000, havn't used it myself for a few years also.

i installed firestarter, and dont know how to set it up, i went thru the wizzard and seemed easy.

from windows when i try to set up the network connection, it wants me to supply a user name and password to connect to the network. Where do i set up in Firestarter this kind of thing?

thanks for your help,

In terms of your network, i don't think the setup you want requires a crossover cable. From what i understand, a crossover cable is for connecting two different networks. If you are going to be using the linux box as a router, you should use a regular cable and have it assign IPs on eth1. (The port going to the laptop).

ruwach · 2004-08-28 20:22:43

ok, another question,
when i try to set this up in windows it is not looking for a gateway, i think, it asks for two dns servers (prefered and alternate)

??????

confused a bit.

ruwach · 2004-08-28 20:44:54

i think i do need a crossover cable. the lights on the nic in the linux box and the little lights on the laptop connection went out when i swithched cables to a straight through one.

shurely you need a crossover cable cuz you connect NIC with NIC :!:

second... on your windoze you have to configure:
eg:
IP: 192.168.0.2
Gateway: 192.168.0.1
DNS: 192.168.0.1

third: ... linux box:
the ethernet for your INTRAnet:
IP: 192.168.0.1
the ethernet for your INTERnet:
(whatever you need to connect to the internet)

till here you should be able to :
Linux ping windoze ... windoze ping linux ... and surfing with linux

now:
in rc.conf add at DEAMONS
iptables BEVORE networking
than go to /etc/conf.d/iptables
there should be a line wich says IP_FORWARDING=0
change 0 to 1

do /etc/rc.d/iptables start

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
-> important!: eth0 if eth0 is the NIC leading to the INTERNET .. if its eth1 than put eth1 there insteat eth0

now you already should be able to ping IP-ADDRESSES in the internet from your windoze-box

additonally you have to set up some DNS-thingie ... pacman -S dnsmasq could do the trick for you... there is a thread on the board about that ... search for dnsmasq

when you have set up that you should be able to surf with windoze

for resource sharing take a look at samba

good luck
