ssh won't forward x11 connections

Hi,

when typing

~$ ssh localhost kvt

I get

_X11TransSocketINETConnect: Can't connect: errno = 101
kvt: cannot connect to X server spy:10.0

This happens also when I try to connect to my machine from the outside. Since
it works on the other three machines I installed, I don't know what to do.

More verbose output (-v):

My /etc/ssh/ssh_config
_________

# This is ssh client systemwide configuration file.  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 various options
