SSH连接到Ubuntu开放SSH服务器通过密码第一

Question

Heyho要求（物理）服务器上登录，

我有一种奇怪的问题与运行开放SSH服务器的Ubuntu的服务器。

除了一件事情之外，所有配置方式都有效。启动后，我无法通过putty与我的.ppk密钥连接到服务器。 我得到一个“服务器拒绝我们的密钥”。由于该东西目前在Virtual Box中运行，我仍然可以通过直接登录进行访问。所以我用我的用户和我的密码登录并立即退出。

现在我可以通过腻子和.ook键连接。我不知道为什么。要么我错过了某个地方的某个解释，或者我在某处配置了某些东西。如果有人能指引我正确的方向，我会很感激！

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

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 

的关键是在描述下的地方，一切，正如所说，我可以连接在重新启动后直接登录在VM后就好了，可是不管我怎么努力我没有一个登录名就无法连接它。

这已被回答很多次，更适合于AskUbuntu。

总之，您已经加密了主文件夹（即使使用您的AuthorizedKeysFile），因此服务器无法验证您的身份。一种可能是将授权密钥移到其他地方（AuthorizedKeysFile /etc/ssh/%u/authorized_keys）并在登录时解密您的个人文件夹，或者只是删除加密。 Official documentation描述得很好。
