<h2> What is "SSH"!?</h2>
|
||
|
|
<br>Are you searching for a program for executing commands on a machine remotely or simply logging into a remote machine?
|
||
|
|
<br>Are you searching a program that provide you secure encryption communications between two host?
|
||
|
|
<br> I have the solution, SSH.
|
||
|
|
<br> SSH connects and logs you into a specified hostname, where the user have only to prove his identity to the remote machine.
|
||
|
|
<br> Briefly The ssh command provides a secure connection between two hosts over a insecure network.
