我正在寻找一种方式来访问密码提示禁用SSH客户端的注意这里
我无法禁用password:
Root Login 的提示.我已将sshd_config
文件更改为:
ChallengeResponseAuthentication no PasswordAuthentication no UsePAM no
并且还更改了权限chmod 700 ~/.ssh
和chmod 600 ~/.ssh/authorized_keys
.我错过了什么?这需要我有密码吗?
详细转储:
debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Offering RSA public key: /home/user/.ssh/id_rsa debug1: Authentications that can continue: publickey,password debug1: Trying private key: /home/user/.ssh/id_dsa debug1: Trying private key: /home/user/.ssh/id_ecdsa debug1: Next authentication method: password
的/ etc/SSH/sshd_config中:

UsePAM no

在 /etc/ssh/sshd_config
# Change to no to disable tunnelled clear text passwords #PasswordAuthentication no
取消注释第二行,如果需要,将yes更改为no.
然后跑
service ssh restart
仅供参考,重启服务的系统方式是:`systemctl restart sshd`这是较新的Ubuntu的默认设置。 (6认同)
许多指南建议在服务器上将ChallengeResponseAuthentication,PasswordAuthentication,UsePAM从yes更改为no.在Debian/Ubuntu下成功测试. (5认同)

跑
service ssh restart
代替
/etc/init.d/ssh restart
这可能会奏效.
在 /etc/ssh/sshd_config
# Change to no to disable tunnelled clear text passwords #PasswordAuthentication no
取消注释第二行,如果需要,将yes更改为no.
然后跑
service ssh restart
这是一个自动执行此操作的脚本
# only allow key based logins sed -n 'H;${x;s/\#PasswordAuthentication yes/PasswordAuthentication no/;p;}' /etc/ssh/sshd_config > tmp_sshd_config cat tmp_sshd_config > /etc/ssh/sshd_config rm tmp_sshd_config
跑
service ssh restart
代替
/etc/init.d/ssh restart
这可能会奏效.
