Failed to establish ssh connection passwordless to run PVM codes

I tried to build PVM code. For that a ssh connection without password is required. I searched a lot and I found a tutorial , I implemented the same, but it didn't work.

My work:-

  1. master is jhamb.

  2. slave is naveen.

  3. Firstly I generate ssh keys on master(jhamb), by using command

    ssh-keygen -t rsa

  4. Then I copied id_rsa.pub file into slave(naveen) machine, by using command

    scp /home/jhamb/.ssh/id_rsa.pub naveen@10.40.54.92:/home/naveen/.ssh/authorized_keys

  5. Then I login into slave from master., by using

    ssh naveen@10.40.54.92

  6. But it always asking for password.

Help me to solve this problem, then only I can configure further for PVM.

Looking for your kind response.

Solution

  • Depending on the ssh version, you might have to do also this: 

     - Put the public key in .ssh/authorized_keys2 
 - Change the permissions of .ssh to 700 
 - Change the permissions of .ssh/authorized_keys2 to 640
