在 Amazon Linux AMI 上启用 SSH 密码登录

我想要能够使用密码而不是密钥文件通过 ssh 登录。
是的，我知道这完全不安全，但此时在配置中，我正在左右打开和关闭变量，试图让它工作。

 
#       $OpenBSD: sshd_config,v 1.73 2005/12/06 22:38:28 reyk Exp $

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/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 change a
# default value.

Port 22
#Protocol 2,1
Protocol 2
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

# HostKey for protocol version 1
#HostKey /etc/ssh/ssh_host_key
# HostKeys for protocol version 2
#HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_dsa_key

# Lifetime and size of ephemeral version 1 server key
#KeyRegenerationInterval 1h
#ServerKeyBits 768

# Logging
# obsoletes QuietMode and FascistLogging
#SyslogFacility AUTH
SyslogFacility AUTHPRIV
#LogLevel INFO

# Authentication:

#LoginGraceTime 2m
PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6

#RSAAuthentication yes
#PubkeyAuthentication yes
#AuthorizedKeysFile     .ssh/authorized_keys

# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
#RhostsRSAAuthentication no
# similar for protocol version 2
#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# RhostsRSAAuthentication and 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 yes


# Change to no to disable s/key passwords
ChallengeResponseAuthentication yes

#GSSAPIAuthentication yes
#GSSAPICleanupCredentials yes
#GSSAPICleanupCredentials yes

# 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 mechanism.
# Depending on your PAM configuration, this may bypass the setting of
# PasswordAuthentication, PermitEmptyPasswords, and
# "PermitRootLogin without-password". If you just want the PAM account and
# session checks to run without PAM authentication, then enable this but set

答案1

您需要更改 ssh 服务器的配置文件并重新启动服务器。

修改 /etc/ssh/sshd_config：

PasswordAuthentication yes

然后重新启动 ssh 服务器：

/etc/init.d/sshd restart

答案2

启用密码验证并删除删除authorized_keys：

# rm /home/ec2-user/.ssh/authorized_keys

答案3

您需要在 sshd_config 文件中设置 GSSAPI 选项并重新启动 sshd 服务。现在 root 直接登录将起作用。我刚刚这样做了，而且成功了。

GSSAPIAuthentication 是 GSSAPICleanupCredentials 否

答案4

标记为正确的答案有效。我发布这篇文章只是因为我认为它无效，而且让我抓狂。

有两个名称相似的文件/etc/ssh/

  • ssh_配置
  • sshd_配置

确保您修改的是正确的一个，sshd_config而不是另一个。
