Very Computer

Here is what I'm trying to figure out how to do:

from a linux box that has a 28.8k dedicated PPP via modemconnection to the net
I have an ethernet card in.  What I want to do is be able to share that internet via ethernet
to another pc running windows.

Any suggestions or ideas?

please respond via email to:

thanks in advance!

If you have a good ISP it's trivial. You have the ISP assign a
subnet to your use, such as three bit (six machines max) and route
packets for that subnet through the address designated as the
gateway. Then you set up simple routing at the gateway machine and
everything works.

If you have an ISP who won't give you a subnet, you will have to
investigate the masquerade patches for Linux, and will be limited to
a certain subset of services. You will also have to use ftp in the
mode which opens the transport sockets from the originating end. I
can't say if your ftp on windoze will support that or not.

Note: I've only used masquerade on 1.2.xx machines as gateways, and
only with Linux machines as clients.

Some ISPs charge a lot for a subnet.  And some PPP conections
dynamically assign the IP number.

Another way of running is to read the Firewall-HOWTO and set up a
system like that.  You don't necessarily have to take all the
precautions if you aren't doing it for security reasons but basically
you set up the linux system with two different networks, the PPP to
the outside world and your local ethernet.

I run this way and run Samba for file sharing locally and a CERN proxy
server for HTTP and FTP proxies.  For telnet I telent to the linux box
first and the telnet out.

So on the Windows (3.11 and 95) machines I can use Netscape and ftp
and even telent.  Any email and other things are done with the linux
box.

I thought about going this way but decided it wasn't worth the
trouble.  I am doing about all I want to do anyway with the proxy
server.
