NAME    [Toc]    [Back]

       ssh-hostbased-setup  -  Sets  up  Secure  Shell host-based
       authentication by verifying and if  necessary,  copying  a
       public host key from a specified remote host

SYNOPSIS    [Toc]    [Back]

       ssh-hostbased-setup [-b] [-u] [-v] filename | hostname

OPTIONS    [Toc]    [Back]

       Contacts a remote host to verify whether or not the remote
       host is issuing the same public host key as the  one  that
       is  stored  on the local host. If the public host keys are
       different, attempts to copy the new public  host  key  and
       rename  and save a backup copy of the old public host key.
       The renamed key is the same name but with the current date
       appended.  Contacts a remote host to verify whether or not
       the remote host is issuing the same public host key as the
       one  that  is stored on the local host. If the public host
       keys are different, attempts to copy the new  public  host
       key  (overwriting  the  existing  key).  Contacts a remote
       host to verify whether or not the remote host  is  issuing
       the  same public host key as the one that is stored on the
       local host. If the public host keys are different, a  message
  is displayed informing the user that the public host
       key for the remote host is different.

              If the public host key is different, the user  must
              enter  the  ssh-hostbased-setup  with  the -b or -u
              option to copy the new key.

OPERANDS    [Toc]    [Back]

       Specifies the name of the file that contains the names  of
       remote  hosts for which host-based authentication is being
       configured or verified. The specified file is usually  the
       file  or  the file.  Specifies the name of the remote host
       for which host-based authentication is being configured or
       verified.

DESCRIPTION    [Toc]    [Back]

       A  local  and remote host must have a copy of each other's
       public host key to use Secure Shell host-based authentication.
 The ssh-hostbased-setup command verifies and if necessary,
 copies the public  host  key  from  the  specified
       remote  host or from the remote hosts listed in the specified
 file to the  /etc/ssh2/knownhosts  directory  on  the
       local host.

       Besides  entering  the ssh-hostbased-setup command, Secure
       Shell host-based authentication requires  additional  configuration.
  See Security Administration for more information
 on configuring Secure  Shell  host-based  authentication.
