Public private key based login to Unix computer

One drawback with username password mode is that there will be requirement to update the password frequently. In such cases, we go for the public key based login.  Required software 1. Putty and puttygen Putty can be downloaded from the download page of  https://www.putty.org/ The downloaded zip contains both putty and puttygen. 2.

This can be downloaded from their official site. https://winscp.net/eng/download.php How it works In the public key based login, we will generate a public key and corresponding private key pair.

'ip' is the latest update or the current command to be used on the latest version of the OS. 2. ping destination_host  This is used to ping the destination server. Bacially, it will simply check the connection to the target. You can interrupt the command with 'ctrl+c'. 3. telnet host port  This command is used to connect to a specific port on the destination server.
