Why create its own local
area network at home or for its small company?
At home it is sometimes advantageous
to create its own network. The reasons can be multiple:
- to play in network with two or several PC.
- to transfer from the files of one PC to the other.
- to share a connection Internet.
- to share resources (printing, scanner, etc...)
- for if required allowing itself to discuss if the stations
what you need, except the computers of course, it is:
- a cross cable if one wishes to connect only two computers.
- a chart network 10/100 for each computer. The chart
network must accept connectors RJ45 (c’ is with
being said the most current charts). Its flow will be
- twisted cables (UTP cat5) with catches RJ45. Before
the purchase, think of measuring the length of cable necessary
to connect the PC to the hub not to have a nasty surprise!!
- a hub 10/100 (case to which one connects cables RJ45
coming from the various computers of the network). All
the computers are connected to the hub. wire on the basis
of the charts networks of the computers are connected
in the ports or catches of the hub. The decision of the
number of port remains to be defined according to the
number of PC which will be connected, without forgetting
that it should be thought in the future (perhaps that
you will still install other computers?).
- a router, if you wish to connect the computers to your
connection Internet because the hub is not sufficient.
If you do not want to invest in a router, you can use
the computer connected directly to connection as a footbridge
(there will have to constantly remain lit when the other
computers of the network wish to reach Internet).
- a switch. Contrary to the hub, the switch analyzes information
arriving on its wearing of entry and filter the data in
order to switch them only on the adequate ports. I.e.
the information sent towards a quite precise computer
will be read only by this computer (if you would not like
only everyone reads personal information!).
Now that all the PC are connected,
the thing which east can be more "hard" to make
and it will be the end, is to parameterize the computers
so that they are in network.
the systems under Windows 95 /98/Me:
Go in the Control panel and click on network. Choose the
Configuration mitre. It is necessary that the following
protocols are installed:
- Customer for the Microsoft networks
- The name of your chart network
- Division of the file and printers for the Microsoft
- Protocol IPX/SPX
So certain lack, click on Installer and add the missing
element. So that you can configure IP addresses of each
computer, click on zone TCP/IP then click on Propriétés.
Do not take IP addresses especially that Windows give
you, if the PC can go on Internet. Do it manually and
choose the addresses which you want to have a better plan,
if not Windows will allot the following addresses:
For the PC n°1
Address IP: 192.168.0.1
Mask of under network: 255.255.255.0
For the PC n°2
Address IP: 192.168.0.2
Mask of under network: 255.255.255.0 and so on .......
Notch the Détecter box connection to the support
Check that the PC belong
well to the same working group, in mitre Identification
in Network. It appears the name of then; computer as well
as the working group to which it belongs. To modify the
working group, and to assign the same one to all the computers,
click on ID network. If you want to divide only certain
files or files, it is enough to go in the Explorer and
to make a right click on the file and chooses Partager,
then Partager as and allots a name to the file such it
will be seen on the PC. Make a right click on the icon
Vicinity network and click on Explorer, choose abstr.
network then on the working group that you created, thus
you will see the computers and all the files that they
the systems under Windows2000/XP:
Go in the Control panel and open Connexions network, open
Connection to the local area network. As for the Windows
95 /98/Me it is necessary that the following protocols
are installed :
- Customer for the Microsoft networks
- File sharing and printers for the Microsoft networks
- Planner of QoS packages
- NETBIOS Nwlink
- compatible Protocol of transport NWLink IPX/SPX/NetBIOS
(for the old plays)
- Protocol Internet TCP/IP
So unquestionable misses, clicks on Installer and adds
the missing element.
To allot IP addresses of the computers, procedure and
identical that that located previously.
On the other hand to check if the PC are well in network,
make a right click on the working station and to select
Propritys, in mitre Name of computer you will be able
to see the working group to which the PC belongs. If you
intend to modify the working group click on ID network.
Here is, your network is in operating
A thing still to be made, do not forget to make daily
updates of your antiviruses and to parameterize your fire
wall well. Also make the updates of the operating systems
because the pirates adore to attack the networks with
viruses or trojans. I take as example the virus which
struck in at the end of 2004: HLP_HEAPINTX.A which is
