You issue the command, specify the file you are sharing, then the user/host we are sharing it with. By default, the file path is /home/user/.ssh/id_rsa.pub. Use the ssh-copy-id command to copy your public key over to the destination system. Sharing keysДЇor all of this to work, you need to share your public key with the remote machines you are trying to SSH to. Let's look at the final step in successful SSH key-based authentication. Once you have generated the keys, they are stored in the /user/home/.ssh/ directory with the following permissions: If you overwrite the existing id_rsa and id_rsa.pub files, you must then replace the old public key with the new one on ALL of the SSH servers that have your old public key. In the example above, the private and public keys are stored in the /home/user/.ssh/key-with-pass and /home/user/.ssh/key-with-pass.pub files, respectively.Дuring further SSH key pair generation, if you do not specify a unique file name, you are prompted for permission to overwrite the existing id_rsa and id_rsa.pub files. Use the -f option to specify the file where the keys will be saved.

The other method is to password-protect your private key so that you are prompted for the password when authenticating (think two-factor authentication using both the private key and the password). This means that if someone gets their hands on your private key, they can use it to authenticate, as well. The result is that you do not have to enter a password when you use your private key for authentication. The convenient way is not to specify a password along with the private key. One is more convenient, and the other is a bit tedious but with added protection to you. Now, there are two ways that you can do this. When you try to log in, the keys are verified, and access is granted. You place the public key in your account home directory on the target server. However, the public key is copied to the target systems that you connect to regularly. The private key file acts as a password and should be kept safe. You generate a public key and a matching private key. Although it can take a little learning, creating and using SSH key-based authentication is worth the investment for every sysadmin. It is objectively true that an encrypted key is a much harder target than a username and password for those with ill intentions. Doesn't sound that bad, right? But, what happens when you need to jump back and forth between systems regularly? Or what if your responsibilities include remote sessions to the same 100 systems throughout the day for health checks? There is another way to accomplish the log in, and with a little upfront investment, it can be far more efficient overall. With traditional SSH authentication, you need the username and password for the account you want to log in to every time that you wish to access a system. I used SSH to remotely connect to thousands of customer machines during my time as a support engineer, and I am sure that others have had a similar experience. Therefore, it makes sense that we should try to improve its use as much as possible. SSH is the single most used remote access protocol in the world. However, I do want to look at a potentially better way to use it. I will not run you through the general concept as it has already been hashed out here at Enable Sysadmin. If you have ever worked as a sysadmin (or you want to in the future), you need a good grasp of SSH. Linux system administration skills assessment.A guide to installing applications on Linux.
