Environment

AAI

CA7 Mainframe Data Provider

Cause

The SFTP connection is unable to authenticate.

Resolution

Verify that the SFTP private and public keys have been generated and the public key is copied over to the AAI server's ~/.ssh/authorized_keys file for the user that is being used to connect to AAI as documented here.

 

Verify the permissions are setup on the directories and files are as below:

On the CA7 side in omvs, the user's home directory will be the user starting the STC below:

chmod 700 <user’s home directory>

chmod 700 <user's home directory>/.ssh

chmod 600<user's home directory>/.ssh.ssh/id_rsa

 

On the AAI server the user's home directory will be the user being used to connect to the AAI server via SFTP:

chmod 700 ~/.ssh

chmod 600 ~/.ssh/authorized_keys

 

Once this is set attempt to start the STC again.
