Remote administration of Linux
Linux installation comes with Perl pre-loaded, but in case you did not
install Perl, I would suggest that you download the latest compiled
binaries from its homepage located at http://www.perl.com.
Having downloaded the Webmin rpm, login into your system as root.
Now change into the directory where you have downloaded the Webmin
RPM and issue the following command.
rpm -ivh webmin-0.82.rpm
Now that Webmin is installed, administering your Linux box is going to be
a piece of cake. Load your browser and point it to http://localhost:10000
Localhost represents the hostname you have assigned your machine and 10000
is the port on which Webmin listens to requests. For security reasons I
would suggest changing this port, keeping in mind that you can only use
ports between 1024 - 65,535. I'll cover this next.
O.K, so you GUI lovers ultimately have something to really cheer about. On
an operating system whose administration could be simply performed via the
command line, GUI options are not very popular. But as I mentioned
earlier, novices will find them a welcome feature.
Beware of the default settings of Webmin, it's open for the world to
connect to, but of course it does have passwords, supports SSL and et al.
The first thing that you need to do after installation is to change those
default settings to make your setup more secure.
There are three main settings that need to be modified in Webmin, one is
the PORT on which Webmin listens, the interfaces on which Webmin will
receive connections and the other is a list of the remote IP addresses
which can connect to Webmin.
Lets change the port on which Webmin listens as well as the IP address on
which it will accept requests. After having logged into Webmin click on
the icon mentioned below.
On the page that is displayed click on the following icon.
Port and Addresses
The first option is the IP addresses on which Webmin will accept
connections. The whole point here is that, the local machine on which
Webmin is running may have several static and dynamic interfaces. You may
be connected to the Internet in more ways then one, and you surely don't
want Webmin to be accessible to everyone. That's the reason why you have
