SSH連接到Ubuntu開放SSH服務器通過密碼第一

Question

Heyho要求（物理）服務器上登錄，

我有一種奇怪的問題與運行開放SSH服務器的Ubuntu的服務器。

除了一件事情之外，所有配置方式都有效。啓動後，我無法通過putty與我的.ppk密鑰連接到服務器。 我得到一個「服務器拒絕我們的密鑰」。由於該東西目前在Virtual Box中運行，我仍然可以通過直接登錄進行訪問。所以我用我的用戶和我的密碼登錄並立即退出。

現在我可以通過膩子和.ook鍵連接。我不知道爲什麼。要麼我錯過了某個地方的某個解釋，或者我在某處配置了某些東西。如果有人能指引我正確的方向，我會很感激！

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 no 

# Lifetime and size of ephemeral version 1 server key 
KeyRegenerationInterval 3600 
ServerKeyBits 1024 

# Logging 
SyslogFacility AUTH 
LogLevel INFO 

# Authentication: 
LoginGraceTime 120 
PermitRootLogin no 
StrictModes no 

RSAAuthentication yes 
#PubkeyAuthentication yes 
AuthorizedKeysFile  .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 
#KerberosTicketCleanup yes 

# GSSAPI options 
#GSSAPIAuthentication no 
#GSSAPICleanupCredentials yes 

X11Forwarding yes 
X11DisplayOffset 10 
PrintMotd no 
PrintLastLog yes 
TCPKeepAlive yes 
UseLogin yes 

#MaxStartups 10:30:60 
#Banner /etc/issue.net 

# Allow client to pass locale environment variables 
AcceptEnv LANG LC_* 

Subsystem sftp /usr/lib/openssh/sftp-server 

# Set this to 'yes' to enable PAM authentication, account processing, 
# and session processing. If this is enabled, PAM authentication will 
# be allowed through the ChallengeResponseAuthentication and 
# PasswordAuthentication. Depending on your PAM configuration, 
# PAM authentication via ChallengeResponseAuthentication may bypass 
# the setting of "PermitRootLogin without-password". 
# If you just want the PAM account and session checks to run without 
# PAM authentication, then enable this but set PasswordAuthentication 
# and ChallengeResponseAuthentication to 'no'. 
UsePAM no 

AllowTcpForwarding yes 

的關鍵是在描述下的地方，一切，正如所說，我可以連接在重新啓動後直接登錄在VM後就好了，可是不管我怎麼努力我沒有一個登錄名就無法連接它。

這已被回答很多次，更適合於AskUbuntu。

總之，您已經加密了主文件夾（即使使用您的AuthorizedKeysFile），因此服務器無法驗證您的身份。一種可能是將授權密鑰移到其他地方（AuthorizedKeysFile /etc/ssh/%u/authorized_keys）並在登錄時解密您的個人文件夾，或者只是刪除加密。 Official documentation描述得很好。
