6. PUTTY
What is Putty?
 Putty is a client program for the secure shell(SSH), Telnet
and Rlogin using network protocols. These use remote
session on a computer over the network. Putty
implements the client end session at which the session is
displayed, rather than the end at which it runs.
How does it work?
 By double clicking putty icon, it opens a window.
Then, anything you type into that window is sent straight
to the UNIX server and everything the UNIX server sends
back is displayed in the window. By having internet
connection, you can work on the server from any part of
the world

8. TELNET VS SSH
SSH(Secure Shell) Telnet
Runs on port 22 Runs on port 23
Very Secure Protocol Not Secure Protocol
Only major protocol to access Joint abbreviation
Difficult to decrypt No data encryption
All popular Operating System Linux , Windows

10. WIRESHARK
What is Wireshark
 Network packet/protocol analyzer
 One of the best open source packet analyzers available today for
UNIX and Windows
Where it use?
 Network administrators use it to troubleshoot network problems
 Network security engineers use it to exam security problems
 Developers use it to debug protocol implementations
 Testers use it to detect defects
 People use it to learn network protocol internals
