General questions about Linux
Which distribution should I use?
Good question! All Linux distributions are
different, some are geared towards different types of
uses, such as for a desktop system, or for a server,
and some are geared towards different groups. Red Hat
Enterprise Linux is aimed at companies, for example,
whereas Mandriva is targeted more at home and desktop
users.
Some of the most commonly used distributions at
the moment are (in alphabetical order):
Debian For more information on Debian, visit ,
Fedora Core ,
Gentoo ,
Mandriva ,
Red Hat Enterprise Linux ,
Slackware ,
SUSE ,
and Ubuntu .
There are literally dozens of others, though.
I don't have access to a fast Internet
connection, where can I get hold of Linux installation
media?
There are several ways of getting installation
media, for example:
CDs are often available at GLLUG
events, see the website for details of
the next meeting.
Look out for distributions given
away with Linux magazines such as Linux
Format ,
Linux User & Developer
,
and Linux Magazine
.
Ask on the mailing list, several
members are happy to post Linux CDs on
request.
There are several companies who
sell cheap unbranded CD sets such as
Linux Emporium.
This company also gives
away slightly out of date
Debian install CDs for just the cost of
the postage. Use this CD to install
your base system and then update it
using Debian's built in tools.
The Ubuntu project will send you
a free installation CD. See here.
I'm worried about the security of my Linux
server/workstation, what basic steps can I take to
minimise potential problems?
There are several things you can to to help
safeguard your computer system, for example:
Create a user other than root. If
you install Linux yourself your
distribution may well ask you to do
this. Make sure the password for this
account is different from your root
password. This will improve your
security, and also make it much harder
for you to damage your system by
accident.
Make both passwords long, and not
based upon a dictionary word. In many
distributions the
passwd command
will warn you if your choice of
password is insecure.
Pick the highest security options
whenever prompted. It is easier to turn
some security precautions off if needed
than to recover a compromised system.
If your distribution supports it, when
installing, seriously consider turning
SELinux on.
Never run any program received
via email, IRC or any other source
unless you know the person who sent it,
and know that they meant to send it
(i.e. it was not sent from their account
by a virus or worm).
Consider buying a dedicated
router for your broadband connection.
For a new user this will be much easier
to set up, and most will provide a
basic firewall, preventing external
machines from connecting directly to
your Linux PC. These units are often
smaller, quieter, are less prone to
breakage and use less power and emit
less heat than a full size PC.
Although you are less likely to
be susceptible to viruses, worms or
trojans downloaded from the Internet,
still take care. Scams which attempt to
get bank details or passwords
(sometimes known as
phishing) can
affect you no matter what OS you use.
Consider joining a Linux User
Group (LUG). These are generally
inhabited by friendly people and
normally have mailing lists as well as
actual meetings where you can pick the
brains of experienced users.
