It also tells you that your key length is 2048 bits which is the default value and is considered secure these days. You will see an output as follows:įrom the output, we can see that it created a private-public key pair saved in /home/pi/.ssh/id_rsa and /home/pi/.ssh/id_rsa.pub respectively. When asked to enter a passphrase, just hit ENTER (we’ll get back to this later). NOTE: For all the following prompts just hit enter. It allows you to connect to a remote host without necessarily having to type in a password. Passwordless ssh is based on public key cryptography. In addition, if you need to write a script that includes accessing remote hosts, then using password authentication makes the script impractical. The two main drawbacks of using passwords are that you have to remember them and they are insecure against brute force and dictionary attacks.

You will be prompted to enter a password, and after that, you will connect to the remote Linux host. Ssh which case, user_name is the user login name of the account you are connecting to, and destination (IP or FQDN) is the host that you are connecting to. If you use a terminal (MAC OS Terminal, Windows 10 Bash Shell, Cygwin), the command to connect to a remote host (e.g. If you are looking to familiarize yourself with the Linux CLI, you might as well purge of as many GUI tools as possible.

Putty) from now on we’ll be using Command Line Interface (CLI) tools such as the MAC OS Terminal, Windows Bash Shell, or Cygwin. NOTE: although there are GUI tools for ssh’ing, (e.g.

In this post, we’ll review how to use it, and more importantly, how to get rid off the password while making ssh more secure and functional. It has become the standard for remote host access. Secure Shell (ssh) came along in 1995 to close the security hole. The main drawback of telnet is that, on un-secure networks, all communication is sent as clear text – even passwords are sent as clear text! In the early days, network engineers and regular Linux/Unix users, used to use telnet to connect to remote or local hosts.
