Public bug reported:

I installed a fresh ubuntu 12.04 desktop with raid0 disks (so I installed postfix - I've read this could be a problem).
If I try to login via ssh to this new machine, I always receive this error:
Read from socket failed: Connection reset by peer

# 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.
