ssh is a quick way to log on and access the file system of your server. From the bash shell on WSL, I would use this command.
$ ssh email@example.com
The remote server will prompt you for the password. You can skip the password step by installing key-based SSH. ( Note:you will still be able to log on using a password on devices without a key pair).
jimmy@WSLBASH:~$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/jimmy/.ssh/id_rsa):
Enter – accept as default
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Enter – leave the passphrase as blank
Your identification has been saved in /home/jimmy/.ssh/id_rsa.
Your public key has been saved in /home/jimmy/.ssh/id_rsa.pub.
The key fingerprint is:
The key's randomart image is:
| .=++..+ oE |
| + =|
| = |
Your output should look something like this.
Now you have a private and public key saved in ~/.ssh/
Copy the public key to your server.
ssh-copy-id -i ~/.ssh/id_rsa.pub yourserver.com
Now you should be able to log in using ssh without having to enter a password. No password means you can start using other useful bash commands such as scp and rsync.
