Sets the SSH host key that Redgate Monitor trusts for a Linux machine.

Syntax

Set-RedgateMonitorSshHostKey [-LinuxMachine] <LinuxMachine> [-SshHostKey] <string> [<CommonParameters>]

Description

The Set-RedgateMonitorSshHostKey cmdlet sets the SSH host key that Redgate Monitor trusts for a Linux machine. Redgate Monitor then connects to the machine only when the machine presents this key.

To get the key, run this command on the machine:

cat /etc/ssh/ssh_host_*_key.pub | ssh-keygen -lf -

The command prints one line for each host key, for example "256 SHA256:uNiVztksCsDhcc0u9e8BujQXVUpKZIDTMczCvj3tD2s root@linux-box (ED25519)". Give one of these lines, as printed, as the SSH host key.

Connect-RedgateMonitor must be called before this cmdlet.
