0 command SSH for Dummy using Bitvise Client

download bitvise client https://www.bitvise.com/ssh-client-download

-setup your login credential using password(we use unbuntu in this example)

1. the server ip address
2. default ssh port is 22
3. username
4. password
5. check the box if you want to store the password
6. save your profile so you can reuse it

• click client key manager, we will generate a new ssh profile(the key pair) general rule: client should create the key pair, not server

• use default setting

optional: you can add passphrase, this is useful in case your key get stolen, but it will prompt you for passphrase every time you try to login (bitvise will not save the passphrase in profile). We will not add passphrase in this example.

• export the public key

1. select the ssh profile you created just now
2. click export
3. export the public key in open ssh format
4. save it in a file, name it to anything you want, in this example, the name is yourpubkey

• finally login(click the login button at the bottom) to your server using password. After login successful, click on the New SFTP window on the left bar.

• go to home and create a .ssh folder

• inside the .ssh folder, create a authorized_keys file

• double click authorized_keys file and open it with notepad

• now open yourpubkey and copy the content to authorized_keys and save authorized_keys, the content should look like this:

• now we can test the ssh connection, logout(click log out at the bottom) the current session and try to login with ssh. Change the method to public key and use auto client key

you should be able to login now, enjoy!

If you want to add new public key to your server, open the same authorized_keys file, append the new key one line under the old key

extra:
you may want to disable password login

1. edit the ssh config
   sudo nano /etc/ssh/sshd_config

2. find this line
   #PasswordAuthentication yes

3. change it to (remember to remove the #)
   PasswordAuthentication no

4. save the file and restart ssh
   sudo systemctl restart ssh

make sure your ssh is working before you try to disable password login!
