3 # This is the sshd server system-wide configuration file. See
4 # sshd_config(5) for more information.
6 # This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
8 # The strategy used for options in the default sshd_config shipped with
9 # OpenSSH is to specify options with their default value where
10 # possible, but leave them commented. Uncommented options override the
15 #ListenAddress 0.0.0.0

24 #RekeyLimit default none
33 #PermitRootLogin prohibit-password
38 #PubkeyAuthentication yes
40 # The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2

74 # Set this to 'yes' to enable PAM authentication, account processing,
75 # and session processing. If this is enabled, PAM authentication will
76 # be allowed through the ChallengeResponseAuthentication and
77 # PasswordAuthentication. Depending on your PAM configuration,
78 # PAM authentication via ChallengeResponseAuthentication may bypass
79 # the setting of "PermitRootLogin without-password".
80 # If you just want the PAM account and session checks to run without
