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
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
45 #RSAAuthentication yes
46 #PubkeyAuthentication yes
48 # The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
49 # but this is overridden so installations will only check .ssh/authorized_keys
50 AuthorizedKeysFile .ssh/authorized_keys
52 # For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
53 #RhostsRSAAuthentication no
54 # similar for protocol version 2
55 #HostbasedAuthentication no
56 # Change to yes if you don't trust ~/.ssh/known_hosts for
57 # RhostsRSAAuthentication and HostbasedAuthentication
58 #IgnoreUserKnownHosts no
59 # Don't read the user's ~/.rhosts and ~/.shosts files
62 # To disable tunneled clear text passwords, change to no here!
63 #PasswordAuthentication yes
64 #PermitEmptyPasswords no
66 # Change to no to disable s/key passwords
67 #ChallengeResponseAuthentication yes
70 #KerberosAuthentication no
71 #KerberosOrLocalPasswd yes
72 #KerberosTicketCleanup yes
73 #KerberosGetAFSToken no
76 #GSSAPIAuthentication no
77 #GSSAPICleanupCredentials yes
79 # Set this to 'yes' to enable PAM authentication, account processing,
80 # and session processing. If this is enabled, PAM authentication will
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
86 # PAM authentication, then enable this but set PasswordAuthentication
87 # and ChallengeResponseAuthentication to 'no'.
