我已经设置我的服务器，以允许sftp使用密码，但是我得到Authentication failed. 即使我使用了正确的密码。 这是我的sshd_config

 # Package generated configuration file # See the sshd_config(5) manpage for details # What ports, IPs and protocols we listen for Port 22 # Use these options to restrict which interfaces/protocols sshd will bind to #ListenAddress :: #ListenAddress 0.0.0.0 Protocol 2 # HostKeys for protocol version 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key HostKey /etc/ssh/ssh_host_ecdsa_key HostKey /etc/ssh/ssh_host_ed25519_key #Privilege Separation is turned on for security UsePrivilegeSeparation yes # Lifetime and size of ephemeral version 1 server key KeyRegenerationInterval 3600 ServerKeyBits 1024 # Logging SyslogFacility AUTH LogLevel INFO # Authentication: LoginGraceTime 120 PermitRootLogin yes StrictModes yes RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys # Don't read the user's ~/.rhosts and ~/.shosts files IgnoreRhosts yes # For this to work you will also need host keys in /etc/ssh_known_hosts RhostsRSAAuthentication no # similar for protocol version 2 HostbasedAuthentication no # Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication #IgnoreUserKnownHosts yes # To enable empty passwords, change to yes (NOT RECOMMENDED) PermitEmptyPasswords no # Change to yes to enable challenge-response passwords (beware issues with # some PAM modules and threads) ChallengeResponseAuthentication no # Change to no to disable tunnelled clear text passwords PasswordAuthentication no # Kerberos options #KerberosAuthentication no #KerberosGetAFSToken no #KerberosOrLocalPasswd yes # GSSAPI options #GSSAPIAuthentication no #GSSAPICleanupCredentials yes X11Forwarding yes X11DisplayOffset 10 PrintMotd no PrintLastLog yes TCPKeepAlive yes #UseLogin no #MaxStartups 10:30:60 #Banner /etc/issue.net # Allow client to pass locale environment variables AcceptEnv LANG LC_* Subsystem sftp internal-sftp -f AUTH -l DEBUG3 # Set this to 'yes' to enable PAM authentication, account processing, # and session processing.

UsePAM yes # Begin SFTP-Server block Match Group www-data ChrootDirectory %h AllowTCPForwarding no X11Forwarding no ForceCommand internal-sftp PasswordAuthentication yes # End SFTP-Server block 

正如你可以注意到在Match Group的最后一行，我已经设置PasswordAuthentication yes我也确保我的用户是www-data一部分，但我仍然无法使用密码login。 我可以没有密码的SSH，但我故意删除我的服务器上的密钥，以testing如果我只能用密码sftp或密钥需要在authorized_keys能够login除了密码？ 我也确定我重新启动了SSH服务来应用这些更改。 我究竟做错了什么？

这里是我的FileZilla的日志：

 Status: Connecting to clone-stage-wplogic-net... Response: fzSftp started, protocol_version=4 Command: open "dummyuser@clone-stage-wplogic-net" 22 Command: Trust new Hostkey: Once Error: Disconnected: No supported authentication methods available (server sent: publickey) Error: Could not connect to server Status: Waiting to retry... Status: Connecting to clone-stage-wplogic-net... 

这里是我的/var/log/auth.log文件的内容：

• 尝试在Solaris 11.3 VM上安装golang
• Azure DNS或内置的Office 365 DNS服务
• 在我的服务器的IP上使用telnet时的随机域
• 具有Active Directory本地用户帐户的域控制器
• 托pipe公司如何知道我的域名？
