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 change a
15 #ListenAddress 0.0.0.0
18 # The default requires explicit activation of protocol 1
21 # HostKey for protocol version 1
22 #HostKey /etc/ssh/ssh_host_key
23 # HostKeys for protocol version 2
24 #HostKey /etc/ssh/ssh_host_rsa_key
25 #HostKey /etc/ssh/ssh_host_dsa_key
26 #HostKey /etc/ssh/ssh_host_ecdsa_key
28 # Lifetime and size of ephemeral version 1 server key
29 #KeyRegenerationInterval 1h
33 # obsoletes QuietMode and FascistLogging
40 # See /usr/share/doc/openssh-server/README.Debian.gz.

81 # be allowed through the ChallengeResponseAuthentication and
82 # PasswordAuthentication. Depending on your PAM configuration,
83 # PAM authentication via ChallengeResponseAuthentication may bypass
84 # the setting of "PermitRootLogin without-password".
85 # If you just want the PAM account and session checks to run without
