1. Start TeraTerm and select "Setup"-> "SSH Key Generator" from the menu bar.
2. Check DSA.
3. Enter the passphrase in Key passphrase Re-enter in Confirm passphrase.
4. Click Generate to create your public and private keys
5. Click Save puplic key to save the public key (
6. Click Save private key to save the private key (id_dsa)

A passphrase is a password. To connect with SSH, create a public / private key pair. You will move the public key to the server later.

Upload public key

Upload the public key. Let's upload it to the home directory of the logged-in user once. The public key is

It is the one. Don't mistake it for your private key.
