    Great tutorial! Very clear…I took 5 minutes to set up my computers

    Great tutorial – best I’ve seen and I’ve been looking for a while. There are a couple of places where its not quite clear, for example “your password” presumably means you/me as root, but the reader might think its Sheen’s password (perhaps Sheena is the user/owner at the other end etc.. And if the destination machine has a different password presumably its for that machine for you/me and not the one for your/my source machine etc.

    This is a great tutorial, nonetheless maybe it should be updated to learn folks how to generate even stronger RSA keys.

  4. pintu says:

    After the whole process I am not able to login without password.

  5. Min says:

    Question: What happens if the users tecmint or sheena’s password are changed? Can sheena still log into 192.168.0.11 and then to server 192.168.0.12 as tecmint user without password to execute anything?

    Thank you.

      @Min,

      Yes, even after password change user able to login without any password, as SSH works on Key authentication.

    Tried using the -copy-id but got the error message command does not exist.

    is it available in some newer vesrions

    • DjK4M5Y5 says:

      ssh-copy-id is a binary from standard package named ‘openssh-client’. If you are using system newer that 2010 I guess you should have it :)

  9. DjK4M5Y5 says:

    Ever heard of ssh-copy-id ? :) You can replace this whole tutorial to just two steps :)

    On machine from you login to other machine
    1. ssh-keygen -t rsa
    2. ssh-copy-id [email protected]
    3. provide password and voilla – that’s it

    • Matt says:

      Interesting fact: the ssh-copy-id “binary” is actually a shell script located in the bin folder, marked executable. So, if you need to work with ssh servers that need to use (for instance) a port other than 22, you can edit the binary with a text editor.
