2000 does not use winipcfg
I am still learning linux, so please =
take any=20
Linux advice i give with a grain of salt. However, if you want =
the IP=20
address of the cable modem ethernet card, LAN card, and the dns =
servers, boot=20
to windows and click srart>run. Enter winipcfg in the box, and =
click ok.=20
This brings up a window that shows you all your network info. There is =
a pull=20
down box for each ethernet adapter. You may need to click the =
"more=20
info" button to get some of the info you need. For the dns server =
ip's, click=20
the button that has three periods to the right of the box, and it=20
should give you three different addresses. I would recommend =
writing=20
all the info down, including the adapter addresses. This may be doable =
in=20
Linux, but I do not know how to do it.
As far as setting up your system, I=20
am trying to do the same thing as you and this is a mini roadmap =
for what=20
I think should be done.
1) get the linux(server) box =
connected to the=20
web.
2) Set up home network and test it =
with=20
ping
3) Get IP forwarding(NAT)=20
working
4) Get firewall working
5) set up samba
6) move my printer onto the server =
and try to get=20
it to work.
7) I would eventually like to set up =
apache to=20
serve a web page that is reaching a little far for me right now=20
though.
For getting the server computer to =
see the=20
internet, make sure to follow the advice I was given by David=20
Mandala,
In=20
the /etc/sysconfig/network-scripts/ifcfg-eth0 script add a line that =
reads=20
"DHCP_HOSTNAME=3D'your hostname as assinged by cox @home'" and then do =
ifup=20
eth0.That seemed to =
help=20
me.
To make sure the computers are =
seeing each=20
other, on the win systems open a dos prompt and ping the =
server.
On the linux box, open a console =
window=20
and use ping on the windows boxes.
As for getting the NAT to work, =
I am=20
afraid i am in the same boat as you. I can get my win 98 and ME =
computers to=20
ping the server, but netwok translation still does not work. I think =
that I=20
need to make sure I set the domain on my linux box to to the same as =
my=20
windows boxes. I may need to set up the "work group" up too. I have =
been=20
working long days the last four days so I have not had a chance to =
look at=20
it.
I hope this helps, I will let =
you know if=20
I find anything new.

Subject: slackware firewall =
for=20
internal windows network
I'm setting up a firewall for an internal network at =
home=20
mainly to keep security inside the network, and to maximize internal =
network=20
speed and file sharing capabilities.
I want to be able to =
have the=20
firewall basically transparent using ipfiltering so the two =
computers behind=20
it can still have full access to the internet.
I want to use =
a=20
192.168.0.x internal network address.
The system is a K62 3D =
with two=20
network cards, a 3com 3c905b, and a netgear FA310Tx card. I have =
access to=20
the internet using the 3com and I've gotten the module support for =
the tulip=20
driver for the other card and set up to use the 192.168.0.x network=20
address.
I use a static IP address setup for eth0 on COX@HOME =
and run=20
a DNS server to be able to lookup names, because I can't get it =
connected to=20
COX any other way without knowing their DNS server addresses. (I =
lost the=20
paper and they don't give them out anymore, they want you to use =
DHCP which=20
incidentally I can't get to work right either)
Anyways, right =
about=20
here is where I am confused on what to do next to get it to forward =
packets=20
and masquerade or how to configure it as a router of =
anytype.
I'm=20
using Slackware 8.0 with a newly compiled 2.4.5 kernel with support =
for NAT,=20
routing and many other options that I knew I needed in =
setup.
I've=20
read through the many HOWTOs, and other Guides at the LDP website, =
on=20
routing and firewall setup and a lot of it is for Redhat which is =
enough of=20
a difference to confuse me even more.
Does anyone have any =
knowledge=20
they could pass me, have a setup like this yourself that you could =
share=20
your experiences, or just have some advice for me?
oh yeah, I =
have a=20
hub that I was planning on setting up like this:
Two windows =
2000=20
machines going through a hub, which connects to the linux machine =
through an=20
up port which is connected to the Cable modem with the other =
card.
I=20
want to be able to share files through the two windows machines, and =
even=20
networked drives, but not with the linux machine at all, just those =
two=20
machines.
I did not install samba support because since this =
was the=20
case I didn't think it would be needed.
Ok, where do I=20
start?
