    check your permissions

    make sure that the *right* permissions are set up

    drwx------ 2 virender virender 4096 May 7 04:51 .ssh
    -rw------- 1 virender virender 393 May 7 03:41 .ssh/authorized_keys

    solution verified

    After setting up the proper sshd_config and seeing this issue i was frustrated. But I then adjusted the perms as viren showed and that fixed it! Thanks viren!!!

    Thumbs up Thank you....Thank you...Thank you.....


    The information on setting the permissions ended hours of my frustations....

    On RedHat (bash):

    #Create Keys
    $: ssh-keygen -t rsa

    #Move created id_rsa.pub file to target server - I used sftp
    $: sftp username@server2.mycompany.com
    $: sftp> put $HOME/.ssh/*.pub $HOME/.ssh/authorized_keys


    # Change the permissions on the .ssh file to be the same
    # as mentioned in the post above (Again, Thank You!)

    #The directory .ssh:

    $: chmod u=rwx $HOME/.ssh

    $: ls -al
    drwx------ .ssh

    #The file authorized_keys:

    $: chmod u=rw $home/.ssh/authorized_keys

    $: ls -al
    -rw------- authorized_keys

    # register the keys using ssh-agent and ssh-add
    $: exec ssh-agent bash
    $: ssh-add

    #Start using your connection (here I use scp to copy file
    #in batch mode(does not prompt for username/password)

    scp -B $HOME/some_directory/* myuser@server2.mycompany.com:/disk1/some_other_directory/
