我正在尝试将我的 ssh 密钥添加到服务器，这样我就不必在 ssh 时输入密码。
我
ssh-copy-id -i ~/.ssh/id_rsa.pub YOUR_USER_NAME@IP_ADDRESS_OF_THE_SERVER从本教程现在我可以在目标服务器上看到我的密钥了/root/.ssh/authorized_keys。但是，当我从主服务器 ssh 进入机器时，我仍然必须输入密码，所以出了问题。有什么想法吗？
我可以确认主服务器上的私钥具有 chmod 600 文件权限。
我检查以确保正确的密钥已被添加到目标服务器，并且确实如此。
然后我运行详细模式进行诊断，但它卡在底部debug3: send packet: type 98

答案1
我正确设置了它。我今天早上醒来后就自动登录了。我猜设置 ssh 密钥时存在传播问题。
