This is a presentation made in MS-Powerpoint 2010. This was made for college presentation. It includes name of Servers and Splunk is also added in it. This is simple and introductory presentation.
2. WHAT ARE SERVERS
O A server is an computer program that
accepts and responds to request made by
another program called client. They are
the storage block of services that a user
need.
O Servers committed to the specific task are
called COMMITTED SERVER. Example:
DNS,FTP etc.
3. NEED OF SERVERS
O All time access to all users.
O The hardware & software is upgraded
according to time.
O All information is at one place.
O No need of technical expertization of any
server related term because the entire tasks
are done by server personnel.
O Data processing is fast.
O Can track record of accessing data.
5. HTTPD
O Its actually the Apache Web Server. It was
launched in 1995.
O HTTPD server works on HTTP function as
a request-response protocol in a client-
server computing model.
O About 51.6% servers all over the world
uses HTTPD.
6. FTP
O File Transfer Protocol(FTP) is a standard
Internet Protocol for transmitting files between
computers on internet over TCP/IP.
O Clients initiate conversations with servers by
requesting to download a file. Using FTP, a
client can upload, download, delete, rename,
move and copy files on a server.
O Content available without login, also known as
anonymous FTP.
O FTP sessions work in passive or active
modes.
7. NFS
O The Network File System (NFS) is a client/server
application that lets a computer user view and
optionally store and update files on a remote
computer as though they were on the user's own
computer.
O NFS uses Remote Procedure Calls (RPC) to route
requests between clients and servers.
O The NFS protocol is one of several distributed file
system standards for network-attached storage
(NAS).
O NFS was originally developed by Sun
Microsystems in the 1980's and is now managed
by the Internet Engineering Task Force (IETF).
8. NIS
O NIS (Network Information System) is a
network naming and administration
system for smaller networks that was
developed by Sun Microsystems.
O Using NIS, each host client or server
computer in the system has knowledge
about the entire system.
O NIS is a UNIX-based program.
9. NTP
O NTP (Network Time Protocol) is a network
protocol that enables you to synchronize
clocks on devices over a network
O The NetBurner NTP server obtains highly
accurate time by synchronizing it’s local
clock to GPS satellites
O NTP Servers are generally categorized in
to several tiered categories- Stratum 0,1 &
2
10. SAMBHA
O Samba is a free software re-
implementation of the SMB/CIFS
networking protocol, and was originally
developed by Andrew Tridgell.
O Samba allows file and print sharing
between computers running Microsoft
Windows and computers running Unix
O Samba provides file and print services for
various Microsoft Windows clients and
can integrate with a Microsoft Windows
Server
11. SSH
O Secure Shell (SSH) is a cryptographic
network protocol for operating network
services securely over an unsecured network.
O SSH was designed as a replacement for
Telnet and for unsecured remote shell
protocols such as the Berkeley rlogin, rsh, and
rexec protocols.
O SSH uses public-key cryptography to
authenticate the remote computer and allow it
to authenticate the user
12. TELNET
O Telnet is an application layer protocol used on
the Internet or local area networks to provide
a bidirectional interactive text-oriented
communication. User data is interspersed in-
band with Telnet control information in an 8-bit
byte oriented data connection over the
Transmission Control Protocol (TCP).
O Telnet was developed in 1969 beginning with
RFC 15, extended in RFC 854, and
standardized as Internet Engineering Task
Force (IETF) Internet Standard STD 8, one of
the first Internet standards.
13. MAIL SERVER
O The terms mail server, mail exchanger,
and MX host may also refer to a computer
performing the MTA function.
O A mail server is a computer that serves as
an electronic post office for email.
14. DHCP
O The TCP/IP protocols include a DHCP
protocol. It automatically assigns and
keeps tabs of IP addresses and any
"subnetworks" that require them.
O DHCP is a part of the "application layer,"
which is just one of the several TCP/IP
protocols. All of the processing and
figuring out of what to send to whom
happens virtually instantly
15. DNS
O The Domain Name System (DNS) is a
hierarchical decentralized naming system
for computers, services, or any resource
connected to the Internet or a private
network.
O The Domain Name System has been in
use since the 1980s.
16. SPLUNK
O Splunk is an American multinataional
corporation that produces software for
searching, monitoring, and analyzing
machine-generated big data
O Splunk has a mission of making machine
data accessible across an organization by
identifying data patterns providing metrics,
diagnosing problems and providing
intelligence for business operations
