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/local/sbin:/usr/local/bin:/usr/bin
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

20 #HostKey /tmp/sshtest/ssh_host_ed25519_key
23 #RekeyLimit default none
32 #PermitRootLogin prohibit-password
37 PubkeyAuthentication yes
39 # The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2

50 # Change to yes if you don't trust ~/.ssh/known_hosts for
51 # HostbasedAuthentication

72 # Set this to 'yes' to enable PAM authentication, account processing,
73 # and session processing. If this is enabled, PAM authentication will
74 # be allowed through the ChallengeResponseAuthentication and
75 # PasswordAuthentication. Depending on your PAM configuration,
76 # PAM authentication via ChallengeResponseAuthentication may bypass
77 # the setting of "PermitRootLogin without-password".
78 # If you just want the PAM account and session checks to run without
79 # PAM authentication, then enable this but set PasswordAuthentication
80 # and ChallengeResponseAuthentication to 'no'.
