ssh problem

Discussion in 'Linux Networking' started by Burkhard Schultheis, Nov 18, 2015.

  1. OS: SLES 11 SP 4
    We have the following problem: We want to establish a ssh connection
    between 2 SLES machines for some users without password. Normally it
    works without a problem, but with 2 new users it does not work.

    What we did is the following:

    as user a on machine A:
    [email protected]> ssh-keygen -t rsa
    no passphrase
    [email protected]> cat ~/.ssh/ | ssh [email protected] 'cat >> .ssh/authorized_keys'

    We use the local /etc/password, the output of "id a" is identical on
    both machines.

    The same procedure is successful for user c, but not for a and b. Where
    should I search for differences between a, b and c?

    Thanks in advance!

  3. log onto B as root. Look at the .ssh/authorized_keys files for each of
    the users a, b and c.
    Look at the .ssh/ files for each of the users a, b, and c on
    machine A. Make sure that they are exactly the same stuff.

    Then make sure that the permission are correct on the .ssh directlry and
    on the files
    It must not be readable, writeable of exactutable by others.
    Also the various files should not be readable or writeable except for
    the user.
