vagrant 禁用密码验证不起作用
vagrant disable password authentication not working
我已经在 vagrant 机器上添加了一个新用户。现在我正在尝试使用 public 密钥和没有密码的新用户通过 ssh 进入流浪汉。
流浪者文件是：
Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/bionic64"
config.vm.network "private_network", ip: "192.168.33.30"
end
然后我通过 vagrant ssh 登录到 vagrant 机器。
然后这就是我将新用户添加到流浪机器的方式：
sudo adduser new_user --disabled-password
sudo su - new_user
mkdir .ssh
chmod 700 .ssh
touch .ssh/authorized_keys
chmod 600 .ssh/authorized_keys
然后我通过
生成了一对新的 public 私钥
ssh-keygen -t rsa -b 2048 -C "email@example.com"
然后我将 public 密钥复制到 .ssh/authorized_keys 文件中。
我还修改了 /etc/ssh/sshd_config 通过更改以下行
PubkeyAuthentication yes
PasswordAuthentication no
ChallengeResponseAuthentication no
然后我尝试通过
从我的机器上 ssh 进入 vagrant
ssh new_user@192.168.33.30 -i ../ssh_keys/vagrant
但它仍然要求输入密码。如何禁用密码？
更新
所以，这些是日志：

vagrant@192.168.33.30's password:
在所有情况下，身份验证都会回退到密码。
除了添加 -v 之外，要检查 ssh 是否使用了正确的密钥，请查看以下内容是否有帮助：
- 使用
ssh -i ../ssh_keys/vagrant new_user@192.168.33.30，确保考虑了 -i 选项
- 确保 public 键被复制为 vagrant 远程机器中的 one 行
~new_user/.ssh/authorized_keys
- 确保私钥不受密码保护（我通常使用
ssh-keygen -t rsa -b 2048 -C "email@example.com" -P ""）
因为ssh vagrant@192.168.33.30 -i ../ssh_keys/vagrant_automation_node -v不行，如果restarting the VM is not enough, activate the debug option on the sshd process
/usr/sbin/sshd -D -dd
# or
/usr/sbin/sshd -D -E /home/<user>/sshd.debug.log
# or
/usr/sbin/sshd -D -dd -f /home/<user>/sshd.debug.log
目的是在服务器端检查您的 public 密钥被拒绝的原因。
来自the discussion, the OP Payam Mesgari确认：
我找到了...
Somehow there was an already existing network adapter on my PC which had the ip address 192.168.33.1 with subnet /24.
Meaning everytime I was trying to ssh into my vagrant machine which was given a static IP of 192.168.33.10, I was actually hitting the other network adapter.
That also explains why nothing was getting logged on the vagrant machine in the sshd...
Basically everytime I was doing anything with an IP address in the subnet 192.168.33.10/24 it was hitting my own adapter on windows, thus never even reached the VMs.
I changed the VMs IP addresses and now everything works
我已经在 vagrant 机器上添加了一个新用户。现在我正在尝试使用 public 密钥和没有密码的新用户通过 ssh 进入流浪汉。

Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/bionic64"

然后我通过 vagrant ssh 登录到 vagrant 机器。

sudo adduser new_user --disabled-password
sudo su - new_user

然后我通过
生成了一对新的 public 私钥ssh-keygen -t rsa -b 2048 -C "email@example.com"
然后我将 public 密钥复制到 .ssh/authorized_keys 文件中。
我还修改了 /etc/ssh/sshd_config 通过更改以下行

vagrant@192.168.33.30's password:
在所有情况下，身份验证都会回退到密码。
除了添加 -v 之外，要检查 ssh 是否使用了正确的密钥，请查看以下内容是否有帮助：
- 使用
ssh -i ../ssh_keys/vagrant new_user@192.168.33.30，确保考虑了 -i 选项 - 确保 public 键被复制为 vagrant 远程机器中的 one 行
~new_user/.ssh/authorized_keys - 确保私钥不受密码保护（我通常使用
ssh-keygen -t rsa -b 2048 -C "email@example.com" -P ""）
因为ssh vagrant@192.168.33.30 -i ../ssh_keys/vagrant_automation_node -v不行，如果restarting the VM is not enough, activate the debug option on the sshd process
/usr/sbin/sshd -D -dd
# or
/usr/sbin/sshd -D -E /home/<user>/sshd.debug.log
# or
/usr/sbin/sshd -D -dd -f /home/<user>/sshd.debug.log
目的是在服务器端检查您的 public 密钥被拒绝的原因。
来自the discussion, the OP Payam Mesgari确认：
我找到了...
Somehow there was an already existing network adapter on my PC which had the ip address 192.168.33.1 with subnet /24.
Meaning everytime I was trying to ssh into my vagrant machine which was given a static IP of 192.168.33.10, I was actually hitting the other network adapter.
That also explains why nothing was getting logged on the vagrant machine in the sshd...Basically everytime I was doing anything with an IP address in the subnet 192.168.33.10/24 it was hitting my own adapter on windows, thus never even reached the VMs.
I changed the VMs IP addresses and now everything works
