This key pair forms a unique combination, with its contents based on hard to crack cryptography. One is called the public key and the other one is called the private key.

What is an SSH key?Īn SSH key essentially consists of two files that belong together. Note that this latter part will be covered in a future article.

Afterwards you can disable SSH logins with a username and password altogether. Ideally you do this as soon as possible after setting up the server. One way of lowering the risk that this unwanted scenario happens is to generate and copy SSH key to server. As the administrator of the server, you want to prevent this nightmare scenario from happening at all cost. Their ultimate goal is to take control of your server. With each connection attempt, they try a different username and password, with the hope that they can login. Those with ill intentions can then run an automated script for continuously trying to gain access via SSH. This works fine, but what about security? For an Internet facing server, it is only a matter of time before someone determines its IP address and figures out that the server accepts SSH connections. Background infoĪfter setting up a Linux server with SSH access, you typically login by providing a username and password.

The instructions provided in this article are written for a Debian PC that connects to a Debian server with SSH. At the same time it adds convenience for you, because it enables you to login without providing a password every time. Logging in by means of an SSH key pair increases security. This tutorial shows you how to generate and copy SSH key to server. Thanks.Do you manage a remote server with SSH and do you login with a username and password? Then it is about time that you switch to an alternative method: one where you identify yourself with an SSH key pair. You should be able to go between Server1 and Server2 without asking for passwords. To be able to go from Server2 to Server1 in the same way and assuming you already have the two rsa file (if not just run the “ssh-keygen” command from the home directory) run the following command You will get asked to enter in the password for the id you are using for password:Īfter entering the correct password you should able to ssh or sftp to Server2 from Server1 without being asked for a password. Scp /home/user1/.ssh/id_rsa.pub 1?.?.?.?:/home/sysadmtg/.ssh/authorized_keys2 Now what you need to do is create a autorized_keys2 file on Server2, do this by doing the following, (make sure you are in the “/” directory before running) Your public key has been saved in /home/user1/.ssh/id_rsa.pub.īlah:1b:42:ba:blah:ec:41:blah:01:blah:73:83:99998:8a:fb:99 now you have created your rsa keys. Your identification has been saved in /home/user1/.ssh/id_rsa. Press enter to blank out the password request for the “passphrase” On Server1 when logged in as the user you wish to use (this example we will use “user1” id)Įnter file in which to save the key (/home/user1/.ssh/id_rsa):Įnter passphrase (empty for no passphrase): Server1 & 2 want to be able to ssh from one server to another without asking for passwords. (this works between two AIX servers, two Linux server or between Linux and AIX servers) There are two servers, Server1 and Server2. It may not be spot on what you need but it could be a good starting place. It just happens that I have just finished a documentation for my company on ssh password. I posted a reply to a simlier question a while back, below is my reply, hope it helps
