This procedure describes how to authorize an SSH host in the Control-M Configuration Manager, which ensures that you connect to the correct SFTP server. The host authorization key might change when you reinstall the SSH server, or if you are working in a cluster environment you need to authorize all nodes in the cluster before creating a connection profile. If the key changed or you did not authorize all cluster nodes, the next job fails, and the output reports HOST NOT AUTHORIZED.
Contact your SFTP server administrator to verify if the signature has changed.
To authorize an SSH host:
From the Control-M Configuration Manager, select the Control-M for File Transfer on the host that you want to manage, right-click and select Authorize SSH Host.
The Authorize SSH Known Host dialog box appears.
In the Host Name field, type the name of the host that you want to authorize.
In the Port field, type the port of the host.
Click Authorize.
If you are working in a cluster environment and need to authorize multiple hosts in the cluster that have different signatures, do the following:
Verify that the SSH Multiple Host Keys checkbox is selected in the Configuration Management dialog box, as described in Configuring Control-M for AFT parameters.
Select Virtual Host.
In the Host Name field, type the name of the host that you want to authorize.
In the Physical Host field, type the cluster logical name, and click Authorize.
