ssh Problem

[Bee Thomas]

Hallo Zusammen,

ich versuche gerade meinen sshd (Linux-Laptop) so zu konfigurieren,  
dass ich mit meinem iMac darauf zugreifen kann.

Leider bekomme ich folgende Fehlermeldung:

imac:~ tb$ ssh tb at 192.168.2.21 -v

Die ssh_config so:

# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options.  For a  
comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.
