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.

If this option is set to yes then remote X11 clients will have full access

to the original X11 display. As virtually no X11 client supports the untrusted

mode correctly we set this to yes.
