12/7/2020 Ssh Key Generated From Server Or Host
This article provides steps for connecting to a cloud server froma computer running Linux® or MacOS® X by using Secure Shell (SSH).It also discusses generating an SSH key and adding a public key tothe server.
Connect to a server by using SSH on Linux or Mac OS XIntroduction
SSH is a protocol through which you can access your cloud server and runshell commands. You can use SSH keys to identify trusted computers withoutthe need for passwords and to interact with your servers.
Apr 14, 2020 You will find yourself employing it frequently to connect to a remote server. It can also be used to generate key pairs or securely transfer files. A very simple example of the “ssh” command is “ssh [email protected]”, which will initiate a connection to the remote host on the IP 33.205.107.72 as a root user. The private host key of the server is stored in /etc/ssh/. The corresponding public key is automatically added (after a prompt) to knownhosts in /.ssh on the client. The purpose of these keys is detect a man-in-the-middle (MITM) attack: If the host key suddenly changes when you type ssh. As usual, and you know nothing has changed on the server, you should get suspicious.
SSH is a protocol through which you can access your cloud server and run shell commands. You can use SSH keys to identify trusted computers without the need for passwords and to interact with your servers. SSH is encrypted with Secure Sockets Layer (SSL), which makes it difficult for these communications to be intercepted and read.

Note: Many of the commands in this article must be run on your localcomputer. The default commands listed are for the Linux command line orMacOS X Terminal. To make SSH connections from Windows®, you can use a clientsimilar to the free program, PuTTY.To generate keys, you can use a related program, PuTTYGen.
Log in
Using the Internet Protocol (IP) address and password for your cloud server, log in byrunning the following
ssh command with username@ipaddress as the argument:

Remote host identification
If you rebuilt your cloud server, you might get the following message:
One of the security features of SSH is that when you log in to a cloudserver, the remote host has its own key that identifies it. When you tryto connect, your SSH client checks the server’s key against any keysthat it has saved from previous connections to that IP address. After yourebuild a cloud server, that remote host key changes, so your computerwarns you of possibly suspicious activity.
To ensure the security of your server, you canuse the web console in the Cloud Control Panel to verify your server’s new key.If you’re confident that you aren’t being spoofed, you can skip thatstep and delete the record of the old SSH host key as follows: Mirnex pro evolution soccer 2015 key generator crack.
On your local computer, edit the SSH
known_hosts file and remove anylines that start with your cloud server’s IP address.
Note: Use the editor of your choice, such as
nano on Debian or theUbuntu operating systemor vi on RPM or CENTOS servers. For simplicity, this article just uses nano . If you prefer to use vi ,substitute vi for nano in the edit commands.For more on using nano , seehttps://support.rackspace.com/how-to/modify-your-hosts-file/.
If you are not using Linux or MacOS X on your local computer, thelocation of the known_hosts file might differ. Refer to your OS forinformation about the file location. PuTTY on Windows gives you theoption to replace the saved host key.
Generate a new SSH key pair
You can secure SSH access to your cloud server against brute forcepassword attacks by using a public-private key pair. A public key is placed onthe server and a matching private key is placed on your local computer. If youconfigure SSH on your server to accept only connections using keys,then no one can log in by using just a password. Connecting clientsare required to use a private key that has a public key registered onthe server. For more on security, reviewLinux server security best practices.
Use the following steps to generate an SSH key pair:
Add the public key to your cloud account
To make it easy to add your key to new cloud servers that you create,upload the public key to your cloud account by following these steps:
If you want to add the key manually, instead of by using the Control Panel, reviewLinux server security best practicesand use the following command:

When you create a new cloud server, you can add a stored key to the newserver.

After you have added the public key to the authorized_keys, you can make an SSHconnection by using your key pair instead of the account password.
Shortcut configuration
Use the following instructions to set up a connection shortcut by creating a~/.ssh/config file on your local computer and adding your server and keydetails to it.
Troubleshooting
If you have trouble making a new connection after you restart theserver, use the following steps to help you resolve the issue:
