helen asks a question to do with PCs, Super_Geek dives in and tries to
help:

Helen,
You do not need a router to connect two PCs together. A DCC (direct
cable connection,) or Crossover cable connection is more suitable.
However, as you have already invested in a dsl router you may find this
an added expense. Being a nice guy I'll look at both options. Even
though I should be revising for GCSE History of USA tomorrow, but this
definitely has priority...
CHANGING YOUR NETWORK
=============================================================
Assuming you want to try the idea, then you must either purchase (or
wire up,) a double male parallel cable or a double female serial cable.
If you have two male/female parallel cables and are a dab hand with a
soldering-iron ([grin]) than I can actually provide you with a wire-up
diagram if you want.
When you have the cables connected to both PCs, WindowsXP helpfully
brings up the network setup wizard, and you can easily do things from
there. BE ADVISED, long (>5m) serial/parallel cables are as expensive as
they are rare, so for longer distances a crossover cable is much better.
This is your friendly CAT5 cable with a minor difference, the
Orange&White stripped wire is swapped with the Green&White stripped.
Don't quote me on that, (it's been a while since I networked the house,)
but the little white box you plug the wires into does have instructions.
When you have the crossover cable set up, the same wizard will guide you
through.
In either case, if you have win98 re-post, because I don't want to go
into the wonders of TCP/IP and its protocols unless I decide to write a
book on it.
Now that you have a network, the main computer now has the only net
connection. This can be shared by going to Start => Network connections
=> [Your DSL connection name]
Select this, and press 'change the settings of this connection' in the
box in the left. From there, go to the 'advanced' tab. Tick all three
boxes in the second box. (You may wish to only tick the first, but it's
up to you.)
You can now deny the other user access (at last,) by going to the
security tab, bringing down the combo box and selecting 'Require secured
password'. Now presumably (because I have never tested it,) this asks
you for a password which you can set. If no password screen appears when
you connect locally, (NOT the dial-up screen if you have one with your
particular DSL,) then tick the box saying 'Automatically use my windows
account'.
The other person now must know the password for the user account to
connect. You could even set up a new user account for this purpose.
NOT CHANGING YOU EXISTING NETWORK
========================================
OK. So your current situation has two PCs connected thus:
[DA INTERNET]
|
______[Router]_______
| |
[Maser PC] [Other PC]
...as I gather. As you can see, the Master PC is not between the 'Other
PC' and the internet, so cannot restrict its use. The software provided
with the router may be able to, but if it was that simple you probably
would have found it.
If not, ZoneAlarm has an option (not sure which version this was
implemented,) to require a password to allow any program to access the
internet. This includes IE. However, one could just close ZoneAlarm. So
without some serious coding, that is not really a good solution.
Whilst pondering over this, my old security motto came to mind.
"Software security has bugs, hardware does not".
Yes it's cheesy, but think. Why not put a metal/wooden box round the
router? Please read on, it's not that insane. The box would have two
holes, and a lockable (padlocked,) door. The cables are in the box,
(through the hole,) but only the 'master pc's' cable is permanently
connected. When the 'Other PC' needs to connect, you unlock the door and
attach the cable! (Don't forget to unplug it when finished.)
There really is no other way that does not involve putting trojan-like
software on the other user's Pc. but that's a good solution too!
(Actually, there may be a legal issue here, so check your position.)
I hope this helps.
According to the law of averages, at least *some* of it should!
