# 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.

# This system is following system-wide crypto policies.
# To modify the crypto properties (Ciphers, MACs, ...), create a *.conf
# file under /etc/ssh/ssh_config.d/ which will be automatically
# included below. For more information, see the manual pages for
# update-crypto-policies(8) and ssh_config(5).

# To modify the system-wide ssh configuration, create a "*.conf" file under
# "/etc/ssh/ssh_config.d/" which will be automatically included below.
# Don't edit this configuration file itself if possible to avoid update
# problems.

# If you do not trust your remote host (or its administrator), you
# should not forward X11 connections to your local X11-display for
# security reasons: Someone stealing the authentification data on the
# remote side (the "spoofed" X-server by the remote sshd) can read your
# keystrokes as you type, just like any other X11 client could do.
# Set this to "no" here for global effect or in your own ~/.ssh/config
# file if you want to have the remote X11 authentification data to 
# expire after twenty minutes after remote login.
