# This is ssh client systemwide configuration file.  See ssh(1) 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 various options
