# This is the sshd server system-wide configuration file. See

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
|
|
# OpenSSH is to specify options with their default value where
|
|
# possible, but leave them commented. Uncommented options override the
|
|
# default value.
