Hi all,

I have two computers, one Windows and one linux; the linux one I want
to setup Samba on, and also have it as a secure server. In other
words, I want to be able to run security tools on the "network"
(crossover cable needed?) - which terminates at a router.

Here is the question: Using SATAN or equivalent tools, how do you
prevent it from going outside the "LAN", so it doesnt start trying to
scan the ISP connected to the router?

Picture:
Spare crossover cable (CAT5)
Computer 1 (one ethernet jack) Computer two (one ethernet jack)
\ //

\ //
CAT5/6 CAT5/6
\ //

|
|-------------------------|
Router (five ports plus one port for feed to
internet)
|
|
ISP < ------------------ > Internet

Tools I want to run on my home "LAN":
SATAN
SAINT
NMap
etc.

Additional question: There is also a unix for windows application
installed on the Windows PC, can this be scanned as well as if it were
an actual unix machine (i.e. it runs init and similar processes, and
can also view ALL windows processes as well)?

Hope that slight question makes sense and TIA.

Me - Just Me

Another question: Does the Linux computer have to be connected to the
other directly, or can they all be plugged into the router and
see/connect to each other?

A few other details --
I want to have a static IP on the linux box, while the others are using
dhcp,
and the linux version is the 7.1 RedHat (Security Enhanced). It will
have all current updates/kernel revisions and patches installed before
it is connected to anything at all other than a power strip.

It would be nice to have the linux computer function not only as a
network security scanner, but a samba server and a firewall as well. I
know this is a horrid idea and generally not recommended, but I'd like
to try to set this up.

The package and tool installation and geral configuration I can do, I
would just like to solicit ideas and suggestions/advice on the
questions.

Doesn't your router have IPSEC security table?
Put local IP or MAC of server in the "Block WAN Access" list
on the router.

Hey Newbie,

Thanks -- checked the setup on the router and it looks okay (not a
security genius, so it probably has issues anyway).

The WAN-blocking idea is in fact set.


Thanks --
