BOOT CAMP 231 (25/06/02)
LIVING WITH BROADBAND, part 4
We’re on the home straight now! If you’ve been following this
short series you should now have your local area network (LAN) up and running,
allowing you to share files on your PCs.
If you are still struggling to get your network working then
now is a good time to run through some basic troubleshooting steps for Windows
9x (Windows XP has its own troubleshooting routines and help wizards). Nine
times out of ten, when you click on Network Neighbourhood and you can’t see
shared disc drives, file folders or resources on other PCs in the network it’s
due to a software problem.
Double check that you have enabled File and Printer Sharing
(see part 2 and this week’s Jargon Filter) and make sure that you have
uninstalled any firewall software running on the server and client PCs. It’s no good just exiting or disabling the
program it must be completely removed! You should also remove any other Internet
monitoring or blocking programs, including virus scanners, (you can put them
back later when the network is operating).
If you are still having difficulty try ‘pinging’ each of the
PCs in the network. Ping is a simple test utility included with all versions of
Windows 9x (ping is a reference to sonar
detection) that checks to see if PCs in the network are connected and able to
communicate with one. It works by sending a ‘packet’ of data, which the other PC
returns. In order to ping a computer (and this can be client to server or server
to client) you need to know the other machine’s IP Address (see part 2).
It’s a good idea to make a note of the IP addresses of the
PCs in your network; you can do this by typing ‘winipcfg’ (without the quotes)
in Run on the Start menu on each machine. Select your Ethernet adaptor from the
drop down menu. In most cases it will have been set automatically to special
networking address that won’t be recognised by the Internet and usually looks
something like 192.168.0.1 (the last digit or digits must be different on each
PC). This is also a useful indicator that the Ethernet adaptor on each PC is
Next, open a DOS window (Start > Programs > MSDOS) and
type ‘ping 192.168.0.1’ (or whatever the IP address is of the PC you are trying
to contact), you should get a fairly immediate response from the other PC, with
four lines of text showing how long it took to send and receive 32 bytes of data
plus some general statistics.
If you get a ‘timed out’ or ‘host unreachable’ reply then you
will have to go back and check through everything methodically. Assuming that
the Ethernet adaptors are working ensure that the TCP/IP protocol has been
properly installed. Go to Network in Control Panel, select the Configuration tab
and look down the list for a TCP/IP entry, followed by an arrow and then the
name of your Ethernet adaptor. The arrow shows that the protocol is ‘bound’ to
the adaptor and that they are working properly. If not try removing and
reinstalling the adaptors and the protocol. Finally, check that the physical
links (cable etc.) or wireless links are okay. If the adaptors and cable get
clean bill of health there’s probably still some software running that messing
up the link so press Ctrl + Alt + Del just once to bring up the Close Program
box and work your way down the list by End Tasking running programs (all except
Systray and Explorer).
Once you are able connect to the other PC in your network you
are ready to share your Internet connection. We’ll be focusing on the software
or ‘proxy’ method, which is easiest if you already have a working broadband or
dial-up connection on your server PC. It’s also the cheapest way as there are
several very good freeware and shareware programs available.
If you’re feeling brave you might want to try your luck with
a Windows utility, called Internet Connection Sharing (ICS), which is included
with all versions of Windows from 98SE onwards. Apparently ICS does work (I’ve
never had much luck with it…) and I would advise novices to steer clear but in
any case before you try it visit www.annoyances.org/exec/show/ics
first for some useful advice.
My personal favourite is a program called CCProxy, a
shareware (free for up to 5 users), which can be downloaded from: www.youngzsoft.com/en/index.html.
Once you get past the jargon and sparse Help files it should prove reliable and
easy to use. Other programs worth investigating are WinGate (http://wingate.deerfield.com/), and
SolidShare (www.solidshare.com). Time
limited trial versions of both programs are available from the respective web
Programs like CCProxy and WinGate only have to be installed
on the sever PC (the one connected to the Internet) and more or less configure
themselves. CCProxy requires some simple adjustments to the client PC’s browser
and email settings – this is where the Help files could be better presented --
and for these you will need to know the IP Address of your server PC and some
basic email settings but it shouldn’t take you more than about five minutes for
each machine on the network.
It really is that simple but you may well find that the whole
thing comes crashing down as soon as you re-install your firewall and Internet
monitoring programs and I have found that our old friend ZoneAlarm can be a real
pain when it comes to networking. Fortunately there is an excellent alternative,
called Agnitum Outpost and it seems to work happily with most Internet sharing
programs. Outpost also has the facility to monitor Internet activity on the
client PCs, which might prove useful for concerned parents. The home version is
freeware and it can be downloaded from: http://www.agnitum.com/products/outpost/.

Pop-up ads are incredibly irritating and they flash up even
quicker with broadband! To date there have been several valiant attempts to
devise software to get rid of them. Here’s another one, called EMS Free Surfer
that, so far seems to defeat 99% of pop-ups but if you’re really determined you
can set it to ‘Strict’ mode, so that only one browser window can be open at a
time, and there’s a ‘Panic’ button that closes all browser windows instantly.
EMS Free Surfer is freeware, it works with all versions of Windows and it can be
downloaded from http://www.free.surfer.tc/.
