By default, the only user who can SSH to the API Gateway is ssgconfig. The following describes how to add other users.
There are some configuration changes that need to be made on the OS. The following steps were performed on a CentOS 7 and RHEL 7 server:
1. Log in to the Gateway as root (Use a privileged shell (root))
2. Edit the file /etc/ssh/ssh_allowed_users
# vi /etc/ssh/ssh_allowed_users
3. Add the name of the user account you would like to have ssh access and save the file
4. Run the command: service sshd restart
