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
16 #ListenAddress 0.0.0.0
19 # HostKey for protocol version 1
20 #HostKey /etc/ssh/ssh_host_key
21 # HostKeys for protocol version 2
22 #HostKey /etc/ssh/ssh_host_rsa_key
23 #HostKey /etc/ssh/ssh_host_dsa_key
25 # Lifetime and size of ephemeral version 1 server key
26 #KeyRegenerationInterval 1h
30 # obsoletes QuietMode and FascistLogging
41 #RSAAuthentication yes
42 #PubkeyAuthentication yes
43 #AuthorizedKeysFile .ssh/authorized_keys
45 # For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
46 #RhostsRSAAuthentication no
47 # similar for protocol version 2
48 #HostbasedAuthentication no
49 # Change to yes if you don't trust ~/.ssh/known_hosts for
50 # RhostsRSAAuthentication and HostbasedAuthentication
51 #IgnoreUserKnownHosts no
52 # Don't read the user's ~/.rhosts and ~/.shosts files
55 # To disable tunneled clear text passwords, change to no here!
56 #PasswordAuthentication yes
57 #PermitEmptyPasswords no
59 # Change to no to disable s/key passwords

63 #KerberosAuthentication no
64 #KerberosOrLocalPasswd yes
65 #KerberosTicketCleanup yes
66 #KerberosGetAFSToken no

69 #AllowSessionHooks yes
70 #SessionHookStartupCmd /bin/true
71 #SessionHookShutdownCmd /bin/true
74 #GSSAPIAuthentication yes
75 #GSSAPICleanupCredentials yes
77 # Set this to 'yes' to enable PAM authentication, account processing,
78 # and session processing. If this is enabled, PAM authentication will
79 # be allowed through the ChallengeResponseAuthentication mechanism.
80 # Depending on your PAM configuration, this may bypass the setting of
81 # PasswordAuthentication, PermitEmptyPasswords, and
82 # "PermitRootLogin without-password". If you just want the PAM account and
83 # session checks to run without PAM authentication, then enable this but set
84 # ChallengeResponseAuthentication=no
