See 5# sshd_config(5) for more information. 6 7# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin 8 9# The strategy used for options in the default sshd_config shipped with 10# OpenSSH is to specify options with their default value where 11# possible, but leave them commented. Uncommented options change a 12# default value. 13 14# Note that some of FreeBSD's defaults differ from OpenBSD's, and 15# FreeBSD has a few additional options. 16 17#VersionAddendum FreeBSD-20110503 18 19#Port 22 20#AddressFamily any 21#ListenAddress 0.0.0.0 22#ListenAddress :: 23 24# The default requires explicit activation of protocol 1 25#Protocol 2 26 27# HostKey for protocol version 1 28#HostKey /etc/ssh/ssh_host_key 29# HostKeys for protocol version 2 30#HostKey /etc/ssh/ssh_host_rsa_key 31#HostKey /etc/ssh/ssh_host_dsa_key 32#HostKey /etc/ssh/ssh_host_ecdsa_key 33 34# Lifetime and size of ephemeral version 1 server key 35#KeyRegenerationInterval 1h 36#ServerKeyBits 1024 37 38# Logging 39# obsoletes QuietMode and FascistLogging 40#SyslogFacility AUTH 41#LogLevel INFO 42 43# Authentication: 44 45#LoginGraceTime 2m 46#PermitRootLogin no 47#StrictModes yes 48#MaxAuthTries 6 49#MaxSessions 10 50 51#RSAAuthentication yes 52#PubkeyAuthentication yes 53#AuthorizedKeysFile .ssh/authorized_keys 54 55# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts 56#RhostsRSAAuthentication no 57# similar for protocol version 2 58#HostbasedAuthentication no 59# Change to yes if you don't trust ~/.ssh/known_hosts for 60# RhostsRSAAuthentication and HostbasedAuthentication 61#IgnoreUserKnownHosts no 62# Don't read the user's ~/.rhosts and ~/.shosts files 63#IgnoreRhosts yes 64 65# Change to yes to enable built-in password authentication. 66#PasswordAuthentication no 67#PermitEmptyPasswords no 68 69# Change to no to disable PAM authentication 70#ChallengeResponseAuthentication yes 71 72# Kerberos options 73#KerberosAuthentication no 74#KerberosOrLocalPasswd yes 75#KerberosTicketCleanup yes 76#KerberosGetAFSToken no 77 78# GSSAPI options 79#GSSAPIAuthentication no 80#GSSAPICleanupCredentials yes 81 82# Set this to 'no' to disable PAM authentication, account processing, 83# and session processing.
