-tdsa 采用dsa加密方式的公钥/私钥对,除了dsa还有rsa方式,rsa方式最短不能小于768字节长度。1、在本地生成一对密钥文件(公钥和私钥)# ssh-keygen# 以上命令等价于 ssh-keygen -t rsa# -t:指定密钥的类型,默认为SSH-2 的rsa类型;[root@localhost ~]# ssh-keygenGenerating public/private rsa key pair. Ente...
[ar1]rsa peer-public-key test Enter "RSA public key" view, return system view with "peer-public-key end". NOTE: The number of the bits of public key must be between 769 and 2048. [ar1-rsa-public-key]public-key-code begin Enter "RSA key code" view, return last view with "publ...
Your public key has been saved in ~/.ssh/id_rsa.pub. 2.发送密钥文件 将密钥公钥文件发送给远端的主机。 ssh-copy-id baixf@192.168.3.9 /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "~/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the...
1、用winscp,sftp, lrzsz,将id_rsa.pub文件上传到/root/.ssh/下面(如果没有则创建此目录),并重命名为:authorized_keys(如果是在Linux服务器上生成的密钥直接执行:mv /root/.ssh/id_rsa.pub/root/.ssh/authorized_keys),再执行:chmod 600 /root/.ssh/authorized_keys修改权限。 2、修改/etc/ssh/sshd_conf...

更详细的主机认证过程是:先进行密钥交换(DH算法)生成session key(rfc文档中称之为shared secret),然后从文件中读取host key,并用host key对session key进行签名,然后对签名后的指纹进行判断。(In SSH, the key exchange is signed with the host key to provide host authentication.来源:https://tools.ietf.org...

Number of key(s) added: 1 Now try logging into the machine, with: "ssh 'it@servera'" and check to make sure that only the key(s) you wanted were added. 通过ssh 连接到 servera,在弹出的窗口里输入私钥的密码(我 workstation 是图形界面的,所有会以弹出窗口的方式,让你输入密钥密码。)。
摘要:本文主要讲解ssh协议相关原理;分别阐述客户端和服务端的使用方法;重点分析ssh基于key验证的方式。 SSH服务 简介:ssh是安全的远程登录协议,基于DH算法做密钥交换,基于RSA或DSA实现身份认证可以远程安全登录服务器,基于C/S结构 具体的软件实现: OpenSSH: ssh协议的开源实现, CentOS默认安装 ...
