3、ssh配置的相关文件在/etc/ssh目录下 ssh-config为client主配置文件 、sshd-config为service主配置文件 、ssh_host_dsa_key为版本2下DSA私匙、 ssh_host_dsa_key.pub为版本2下DSA公匙、ssh_host_rsa_key为版本1下RSA私匙、 ssh_host_rsa_key.pub为版本2下RSA公匙、
打开puttygen.exe 默认key_type为RSA(SSH-2)位数为2048,推荐设置位数4096,点击generate,鼠标随机在上面空白处移动,证书就根据这些随机点产生,等进度条走完即可。 生成key后可以修改comment标识key的用途。 保存public key,如果使用文本编辑器打开,类似下图: 但是更方便的一种做法,是直接拷贝生成的public key,暂存到文...

You now have a public and private key that you can use to authenticate. The next step is to place the public key on your server so that you can use SSH-key-based authentication to log in. Step 2 — Copying the Public Key to Ubuntu Server The quickest way to copy your public key to...
The new public key types and certificates “ecdsa-sk” and “ed25519-sk” support such authentication devices. General handling of private and public key files is unchanged; users can still add a passphrase to the private key. By using a second factor the private SSH key alone is no longer...

Ubuntu 12.04 Introduction The Secure Shell Protocol (or SSH) is a cryptographic network protocol that allows users to securely access a remote computer over an unsecured network. Though SSH supports password-based authentication, it is generally recommended that you use SSH keys instead. SSH keys ...
Ubuntu 开启SSH二次验证(Two-Factor Auth) 谷歌身份验证器 (Google Authenticator) 是 Google 推出的基于时间的一次性密码 (Time-based One-time Password, TOTP) 算法,其与 SSH Password 或 Public Key 配合,在普通 SSH 密码或密钥验证前进行基于 TOTP 的二阶段验证,以提升 SSH 登录安全性。
PubkeyAuthentication yes 该选项在大多数系统上默认为yes。 更多有关SSH密钥身份验证的信息,请参考 How to Setup SSH Key Authentication。 禁用不使用的身份验证方法 Linux管理员知道优秀的安全实践是停止并删除所有用不到的服务,同样,你也应该禁用SSH中不使用的其他任何身份验证方法。 在这里,我将向你展示禁用所有身...
