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 # Disable legacy (protocol version 1) support in the server for new
19 # installations. In future the default will change to require explicit
20 # activation of protocol 1
23 # HostKey for protocol version 1
24 #HostKey /etc/ssh/ssh_host_key
25 # HostKeys for protocol version 2
26 #HostKey /etc/ssh/ssh_host_rsa_key
27 #HostKey /etc/ssh/ssh_host_dsa_key

30 #KeyRegenerationInterval 1h
34 # obsoletes QuietMode and FascistLogging
45 #RSAAuthentication yes
46 #PubkeyAuthentication yes
47 #AuthorizedKeysFile .ssh/authorized_keys
49 # For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
50 #RhostsRSAAuthentication no
51 # similar for protocol version 2
52 #HostbasedAuthentication no
53 # Change to yes if you don't trust ~/.ssh/known_hosts for
54 # RhostsRSAAuthentication and HostbasedAuthentication
55 #IgnoreUserKnownHosts no
56 # Don't read the user's ~/.rhosts and ~/.shosts files
59 # To disable tunneled clear text passwords, change to no here!

83 # Set this to 'yes' to enable PAM authentication, account processing,
84 # and session processing. If this is enabled, PAM authentication will
85 # be allowed through the ChallengeResponseAuthentication and
86 # PasswordAuthentication. Depending on your PAM configuration,
87 # PAM authentication via ChallengeResponseAuthentication may bypass
88 # the setting of "PermitRootLogin without-password".
89 # If you just want the PAM account and session checks to run without
90 # PAM authentication, then enable this but set PasswordAuthentication
91 # and ChallengeResponseAuthentication to 'no'.
