# $OpenBSD: sshd_config,v 1.103 2018/04/09 20:41:22 tj Exp $ # This is the sshd server system-wide configuration file. See # sshd_config(5) for more information. # This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin:/cvmfs/dirac.egi.eu/dirac/v8.0.56/Linux-x86_64/bin # The strategy used for options in the default sshd_config shipped with # OpenSSH is to specify options with their default value where # possible, but leave them commented. Uncommented options override the # default value. # To modify the system-wide sshd configuration, create a *.conf file under # /cvmfs/dirac.egi.eu/dirac/v8.0.56/Linux-x86_64/etc/gsissh/sshd_config.d/ which will be automatically included below Include /cvmfs/dirac.egi.eu/dirac/v8.0.56/Linux-x86_64/etc/gsissh/sshd_config.d/*.conf # If you want to change the port on a SELinux system, you have to tell # SELinux about this change. # semanage port -a -t ssh_port_t -p tcp #PORTNUMBER # #Port 22 #AddressFamily any #ListenAddress 0.0.0.0 #ListenAddress :: #HostKey /cvmfs/dirac.egi.eu/dirac/v8.0.56/Linux-x86_64/etc/gsissh/ssh_host_rsa_key #HostKey /cvmfs/dirac.egi.eu/dirac/v8.0.56/Linux-x86_64/etc/gsissh/ssh_host_ecdsa_key #HostKey /cvmfs/dirac.egi.eu/dirac/v8.0.56/Linux-x86_64/etc/gsissh/ssh_host_ed25519_key # Ciphers and keying #RekeyLimit default none # Logging #SyslogFacility AUTH #LogLevel INFO # Authentication: #LoginGraceTime 2m #PermitRootLogin prohibit-password #StrictModes yes #MaxAuthTries 6 #MaxSessions 10 #PubkeyAuthentication yes # The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2 # but this is overridden so installations will only check .ssh/authorized_keys AuthorizedKeysFile .ssh/authorized_keys #AuthorizedPrincipalsFile none #AuthorizedKeysCommand none #AuthorizedKeysCommandUser nobody # For this to work you will also need host keys in /cvmfs/dirac.egi.eu/dirac/v8.0.56/Linux-x86_64/etc/gsissh/ssh_known_hosts #HostbasedAuthentication no # Change to yes if you don't trust ~/.ssh/known_hosts for # HostbasedAuthentication #IgnoreUserKnownHosts no # Don't read the user's ~/.rhosts and ~/.shosts files #IgnoreRhosts yes # To disable tunneled clear text passwords, change to no here! #PasswordAuthentication yes #PermitEmptyPasswords no # Change to no to disable s/key passwords #ChallengeResponseAuthentication yes # Kerberos options #KerberosAuthentication no #KerberosOrLocalPasswd yes #KerberosTicketCleanup yes #KerberosGetAFSToken no #KerberosUseKuserok yes # GSSAPI options #GSSAPIAuthentication yes #GSSAPIDelegateCredentials yes #GSSAPICleanupCredentials yes #GSSAPIStrictAcceptorCheck yes #GSSAPIKeyExchange yes #GSSAPIEnablek5users no # Set this to 'yes' to enable PAM authentication, account processing, # and session processing.
