9. INTRODUCTION TO LINUX
 Linux is a generic term referring to Unix-like
computer operating systems based on the Linux
kernel.
 Linux can be installed on a wide variety of computer
hardware, ranging from embedded devices such as
mobile phones, smartphones and wristwatches to
mainframes and supercomputers.
 Linux is the most secure operating
system, therefore, most of the severs are using
Linux operating system.

11. Basic Linux Commands Used
 pwd: Displays the path for current working
directory.
 ls: Lists files and subdirectories in a directory.
 ls –l: Gives a long listing for files and subdirectories
in a directory.
 ls –la : Displays also hidden files in addition.
 exit: Ends current session.
 touch: Creates a new empty file.

12.  mkdir: Create a new directory.
 cd: Change directory.
 rmdir: Removes empty directory.
 cat: Concatenate files or read files.
 cp: Copy files from one directory to other.
 mv: Moves file from one directory to other.
 rm: Removes files and directory.

13. NETWORK MANAGEMENT
 Subnetting:-
Splitting a single network into
smaller, separate subnets reduces number of hosts
per network is called subnetting.

14.  Telnet:-
It is a network protocol used on the
Internet or LAN to provide a bidirectional
interactive text-oriented communications
facility(port number 23).

15.  Web-Hosting:-
We have done web hosting by
installing a predefined package called WEBMIN.
Webmin is a web-based interface for
system administration.
Using any modern web browser, you
can setup user accounts, Apache, DNS, file sharing
and much more.

17. DOMAIN NAME SERVER(DNS)
 The Domain Name System maintains the domain
namespace and provides translation services
between two namespaces.

22. WEB MAIL
 The mailing feature acts as a bridge between
different departments which connects employees of
different departments.

23. SECURITY FEATURES
 Firewall:-
A Firewall is a device installed between the
internal network and the global internet.
It is designed to forward some packets and
filter (not forward) others.
It act as a security of information flowing
across the network.

25.  Filter:-
When a program performs operations on
input and writes the result to the standard output, it
is called a filter.
Through filter we can restrict unauthorized
users from entering into unalloted work space.

26.  Permissions:-
Every file or folder in Linux has access
permissions. There are three types of permissions
(what allowed to do with a file):
read access - 5
write access - 7
execute access - 1

27. CONCLUSION
 Our project is an information as well as network
management system to connect and automate all the
department of the company.
 The system contains various servers
(DNS, Apache, Mail) that helps all the department of
the company to upload all information.
 The mail server developed as the part of the project
will give the company a dedicated e-mail service for
all management member and employees.

28. FUTURE SCOPE
 Security measures can be enhanced by using more
secure protocol and hardware firewalls.
 As the number of users increase, more account space
will be required. At that time, moderation in user
quota portioning will become a necessity.
 Better connection solution is required so that users
can access the network from remote locations.
