server ip: server-ip
password: password
user: root

using SSh
command:
-> ssh root@server-ip
then it will asked for password like bellow
root@server-ip's password:
write password and press enter

Now you are in your vps server

In this approach, every command ask password in every time.

If we want to avoid to enter password in every time,
then we need to go two approach
  1. generate private key
  2. authorize public key

 let look at 2nd options:

For this need to find local pc's public key:
-> ls ./.ssh/
above command will show public key if it exists
id_rsa      id_rsa.pub  known_hosts

Then copy the public key file to vps server
-> scp ./.ssh/id_rsa.pub root@107.191.96.40:~/delwar_rsa.pub
then it will asked for password like bellow
root@server-ip's password:
write password and press enter

After that login using SSh
command:
-> ssh root@server-ip
then it will asked for password like bellow
root@server-ip's password:
White password and press enter

Then the last command is
-> cat delwar_rsa.pub >> .ssh/authorized_keys

above command will append local public key to authorized_keys.

Now All is set. Done .


Now when you connect to your vps using
-> ssh root@107.191.96.40

It will never ask you password every time.

 Yahhhhhhh.
