OpenSSH is an Open Source (BSD licensed) suite of secure networking utilities based on the Secure Shell (SSH) protocol, which provides a secure channel over a potentially unsecured network.
How to connect over SSH
To connect from a Unix system to an OpenVMS system running OpenSSH, follow these steps: 1. On the Unix system, generate an ed25519 key pair:
ssh-keygen -t ed25519
2. Once ready, connect to the OpenVMS machine and navigate to the [.SSH] directory of the user:
set def [.ssh]
3. Open the AUTHORIZED_KEYS. file (or create a new one) and paste your public key there:
$ create authorized_keys. ssh-ed25519 AAAAC3NzaC... user@test
4. Use the following command for connecting from your Unix system:
ssh -o "KexAlgorithms +diffie-hellman-group1-sha1"
-o HostKeyAlgorithms=+ssh-dss
-o PubkeyAcceptedAlgorithms=+ssh-dss
user@openvms_system
-i your_key_file
where user is the username on OpenVMS, openvms_system is the IP of your OpenVMS system running OpenSSH, and your_key_file is the path to the private key file on the Unix system generated in step 1.
