Oct 29, 2012 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. Remove little snitch helper. If invoked without any arguments, ssh-keygen will generate an RSA key for use in SSH protocol 2 connections.
Jan 12, 2019 How to know/find out/see my ssh host key A quick qns, how do i find out or see or know my host key? I am using putty on a windows and managed to log in to my linux although it screamed for the unknow host key as usual for 1st time log-in.
Note: This is an RHCSA 7 exam objective and an RHCE 7 exam objective. Instead of connecting through login/password to a remote host, SSH allows you to use key-based authentication. To set up key-based authentication, you need two virtual/physical servers that we will call server1 and server2. Configuration Procedure.
To improve the system security even further, generate SSH key pairs and then enforce key-based authentication by disabling password authentication. To do so, open the /etc/ssh/sshdconfig configuration file in a text editor such as vi or nano, and change the PasswordAuthentication option as follows.
I want to add a user to Red Hat Linux that will not use a password for logging in, but instead use a public key for ssh. This would be on the command line.
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?
You may need a new key file:
Your system is compromised.
Your keys are stolen.
You forgotten the passphrase.
Your application need a new host key.
You can not read the default system key files stored in /etc/ssh/ directory but your non-root application needs key.
You got an error message which read as “Could not load host key: /etc/ssh/ssh_host_key*”.
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: https://heavyastro.weebly.com/office-2010-key-generator-download-free.html.
