Local Ssh Config

Posted : admin On 1/2/2022

SSH, also known as Secure Socket Shell or Secure Shell, is a cryptographic protocol that helps to encrypt communication in unsecured networks where an SSHD is the daemon program for SSH. Together they provide secure communication between two untrusted hosts over an insecure network.

Local Ssh Config

Step 1 : To install it in Ubuntu, use the following command:

Step 2 : You may check its status by running command:

The sshconfig client configuration file has the following format. Both the global /etc/ssh/sshconfig and per-user /ssh/config have the same format. Empty lines and lines starting with '#' are comments. Each line begins with a keyword, followed by argument (s). Unix1.jinr.dubna.su: Failed to get local xauth data. Unix1.jinr.dubna.su: Requesting X11 forwarding with authentication spoofing.

Step 3 : We’re going to edit a /etc/ssh/sshd_config file using the vi editor as the root user, so you should type the following command on the terminal:

Step 4 : Look for a line that contains PermitRootLogin and replace it with the following line:

Ssh Config File Location

Local

Step 5 : Save the /etc/ssh/sshd_config file

Step 6 : Now it’s time to restart the SSH server. Then your server will be installed, configured, and ready to use. You can test this by executing the following command:

Step 7 : You can test your SSH server by trying to connect to it and typing on the terminal the following command:

Step 8 : Now you will see a message asking for your authorization. Type yes and your password. You’re now connected to your our server through the SSH protocol.

Simplifying SSH connections with a config file

Step 1 : A local configuration must be stored in the .ssh directory of your home directory, and be named config. The full path would look something like this:

Ssh Local Config File Name

Step 2 : This file doesn’t exist by default, but if it’s found, SSH will parse it and you’ll be able to benefit from it. Go ahead and open this file in your text editor, such as nano:

Git Local Ssh Config

Step 3 : This config file allows you to type configuration for servers that you connect to often, which can simplify the SSH command automatically, for example:

Local Forward Ssh Config

Step 4 : SSH connections with a config file
