1. SSH to the remote machine: 

   Code Block
   ssh <username>@<remotemachine>

   
   

2. Then confirm the remote machine has a ".ssh" folder in your account's home directory: 

   Code Block
   ls -la ~

   
   

3. If it does not, create the .ssh folder: 

   Code Block
   mkdir ~/.ssh

   
   

4. Now copy your local public key to the remote machine: 

   Code Block
   scp ~/.ssh/id_rsa.pub <username>@<remotemachine>:~/.ssh/<hostmachinename><localmachinename>.pub

   where <hostmachinename> will help identify the source of the public key. 
   
   

5. Now SSH into the remote machine you have copied the file to, and cd to the .ssh directory in your home directory: 

   Code Block
   cd ~/.ssh

   
   

6. You'll see the <hostmachinename>.pub file you just copied over. Add its contents to a file named "authorized_keys": 

   Code Block
   cat ~/.ssh/<hostmachinename>.pub >> ~/.ssh/authorized_keys

   
   

7. Make sure that directory and it's files are only accessible by your account: 

   Code Block
   chmod 700 ~/.ssh chmod go-rwx ~/.ssh/*

   
   

8. Back on the local machine, test SSH:

   Code Block
   ssh <username>@<remotemachine>

   which should result in a login without a password. 
   
   

9. Repeat for every remote machine that does not have a centralized network home directory.
