Question

我正在尝试使用ssh禁用密码身份验证，但它似乎无法正常工作。我已经按照我能找到的每一个方向来解决这个问题，而且它们基本上都是一样的。我修改了/ etc / ssh / ssh_config文件，如下所示：

# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

Host *
#   ForwardAgent no
#   ForwardX11 no
#   ForwardX11Trusted yes
#   RhostsRSAAuthentication no
#   RSAAuthentication yes
#   PubKeyAuthentication yes
#   PasswordAuthentication no
#   HostbasedAuthentication no
#   GSSAPIAuthentication no
#   GSSAPIDelegateCredentials no
#   GSSAPIKeyExchange no
#   GSSAPITrustDNS no
#   BatchMode no
#   CheckHostIP yes
#   AddressFamily any
#   ConnectTimeout 0
#   StrictHostKeyChecking ask
#   IdentityFile ~/.ssh/identity
#   IdentityFile ~/.ssh/id_rsa
#   IdentityFile ~/.ssh/id_dsa
#   Port 22
#   Protocol 2,1
#   Cipher 3des
#   Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc
#   MACs hmac-md5,hmac-sha1,umac-64@openssh.com,hmac-ripemd160
#   EscapeChar ~
#   Tunnel no
#   TunnelDevice any:any
#   PermitLocalCommand no
#   VisualHostKey no
#   ProxyCommand ssh -q -W %h:%p gateway.example.com
#    SendEnv LANG LC_*
#    HashKnownHosts yes
#    GSSAPIAuthentication yes
#    HashKnownHosts yes
#    GSSAPIAuthentication yes
#    GSSAPIDelegateCredentials no
    RSAAuthentication yes
    PubKeyAuthentication yes
    ChallengeResponseAuthentication no
    PasswordAuthentication no
    UsePAM no

然后我尝试重新启动服务，重新启动计算机以及我能想到的所有其他内容，但我仍然可以使用我的密码从其他多台计算机登录到此计算机。这是ssh连接的转储：

$ ssh -v matthew@server
OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011
debug1: Authentications that can continue: publickey,password
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /Users/matthew/.ssh/private_key
debug1: Authentications that can continue: publickey,password
debug1: Next authentication method: password
matthew@server's password: 
debug1: Authentications that can continue: publickey,password
Permission denied, please try again.
matthew@server's password:

公钥连接失败，因为我重命名了我的私钥，故意确保它强制密码验证并且理论上失败。无论如何，它没有，我不能为我的生活弄清楚我做错了什么。

有什么建议吗？

I have modified the /etc/ssh/ssh_config files as follows...

ssh_config是ssh 客户端的配置文件，而不是服务器。要阻止传入SSH连接上的密码身份验证，您需要禁用服务器中的功能。服务器的配置文件为sshd_config，很可能位于/etc/ssh目录中。

sshd_config的手册页here.您最有可能想要设置参数 PasswordAuthentication到“否”。

禁用ssh密码验证
