Part 2
What is SSH ?
Ans: SSH stands for secure shell.
It is used on “unix-like” systems to login to the remote
machines.
To login to the machine we need to know the credentials
of the machine i.e. username and password. we will come
back to this again.
Telnet is yet another option to connect to the machines
remotely but is less secure.
There are various SSH clients- putty for windows ,say
which have their own console and allow us to login to the
machines via SSH.
I will explain this in simple terms: Supose I have two machines:
Computer 1 and computer 2 .
I can switch on computer 1 and login to it to operate it.
There is an alternate option where I switch on the computer 1
and switch on the computer 2 and login to the computer 2.
Now using computer 2 I can login to the computer 1 via a
secure connection SSH.
the so called “Remote login”
Putty ,mobaxterm ,mremote and myraid other tools help us to
do this .
