Linux is a kernel that can be configured as a network operating system or server to perform functions like a DNS, DHCP, web, mail, file/print, or database server. It is important for servers and clients to have IP addresses to communicate on a network. Installing an Ethernet card allows a Linux computer to connect to a network by inserting it into an expansion slot, connecting a network cable, and configuring the IP address. The Linux system should automatically detect the Ethernet card, but the driver may need to be loaded manually by editing configuration files.

1. What Linux is?
Linux itself is just a kernel
(1)

2. Linux can be configured as
a networked workstation
a DNS server,
a DHCP server,
a web server,
a mail server,
a file and print server,
database server,
a firewall,
a gateway router and
many more...

3. User will learn the true meaning of Linux,
which is a network operating system or
server system.
The first thing you should learn about
networking is ip addresses.
A server and a client computer must have
an ip address so that it can be reach in
network environment.

4. Linux server can serves networking 365
days a year without any problem.
Linux is a very stable and secure network
operating system when properly
configured and maintained.
All that starts with setting up a network
card and configure an ip address for the
server.

Ethernet card tutorial is a guide on how to

6. Ethernet card or more commonly known
as network interface card is a required
component if you want to connect to the
network.
Ethernet card is available in two version
which are the PCI slot or the older ISA
card.
However, nowadays computer always
comes with integrated Ethernet with
motherboard.
(ISA = Industry Standard Architecture)
(PCI = Peripheral Component Interconnect)

9. Installing an Ethernet card
[1]
1. Power off your computer.
2. Open computer casing and Install your
PCI Ethernet card in an available PCI
expansion slot (an ISA card into ISA
slot).
3. Close computer casing and plug in
network cable into the Ethernet port
and the other end into the router port
(cat5 cable with RJ-45 socket).

15. Installing an Ethernet card
[2]
4. Power on your computer.
5. Normally Linux will detect the
Ethernet card and load appropriate
kernel when you boot up the system.
However if Linux doesn't detect it, you
must manually configure the Etehrnet
card by loading appropriate module
using modprobe.

6. After Linux has finished boot up, check
/etc/modprobe.conf (Slackware
/etc/modprobe.d/modprobe.conf)
that appropriate kernel has been
loaded.
7. Type less /etc/modprobe.conf and
verify that the alias eth0 has been
created (and eth1 if you installed
second Ethernet card).

17. Installing an Ethernet card
[2]
6. Type less /etc/modprobe.conf and
verify that the alias eth0 has been
created (and eth1 if you installed
second Ethernet card). If not then you
may need to manually edit this file and
create the appropriate alias. If you
don’t, you’ll lose your networking
configuration when the system
reboots.
you 're done, then it time to configure the ip address for the
Ethernet card
