Linux Generate Ssh_host_dsa_key

How do I create a host key file to use with my applications as I can not use system defined /etc/ssh/ssh_host_rsa_key for non-root account under Linux / Unix / Apple OS X / *BSD operating systems?
You need to use a command called ssh-keygen. This command generates, manages and converts authentication keys for ssh. It can create RSA keys for use by SSH protocol version 1 and RSA or DSA keys for use by SSH protocol version 2. he type of key to be generated is specified with the -t option. If invoked without any arguments, ssh-keygen will generate an RSA key for use in SSH protocol 2 connections. The -f option specifies the filename of the key file.

Why create a new host key files?

Jun 13, 2019 These instructions were tested on Ubuntu, Fedora, and Manjaro distributions of Linux. In all cases the process was identical, and there was no need to install any new software on any of the test machines. To generate your SSH keys, type the following command: ssh-keygen. The generation process starts.

Ssh Dsa

  1. Your system is compromised.
  2. Your keys are stolen.
  3. You forgotten the passphrase.
  4. Your application need a new host key.
  5. You can not read the default system key files stored in /etc/ssh/ directory but your non-root application needs key.
  6. You got an error message which read as “Could not load host key: /etc/ssh/ssh_host_key*”.

ssh-keygen Syntax

The syntax is:

Example

Create a host key file in your $HOME/.ssh/myapp as follows. First, create a directory to store your host key file, enter:
$ mkdir -p $HOME/.ssh/myapp
To create a host RSAv2 key file, run:
$ ssh-keygen -t rsa -f $HOME/.ssh/myapp/rsa_key_file
Sample outputs:

Type the following commands to verify the keys:
$ ls -l $HOME/.ssh/myapp/
Sample outputs:

You can now use keys with your app:
$ mycool-app -key $HOME/.ssh/myapp/rsa_key_file -d
