Hello Guys, How can I define the sequence in which the SSH client attempts different authentication methods when connecting to a remote host?

Thank you, Jenn :girl:

Hello Jennifer,

The PreferredAuthentications option determines the order in which the SSH client tries different authentication methods during connection. This lets you prioritize one method (for example keyboard-interactive) over another (such as password).

To set this order, you should add the PreferredAuthentications directive to the /etc/ssh/ssh_config file, followed by the list of authentication methods in your desired sequence.

First, open the ssh_config file with following command.

 # vim /etc/ssh/ssh_config

First, open the ssh_config file and add the following lines and save it.

 PreferredAuthentications    password,keyboard-interactive,publickey,hostbased,gssapi-with-mic

The default authentication order in RHEL 6 and RHEL 7 is:

gssapi-with-mic,hostbased,publickey,keyboard-interactive,password

Let me know if you need more help on this.
