ssh -A 参数使用示例

将公钥拷贝到192.168.90.164

[[email protected] ~]$ ssh-copy-id [email protected]

The authenticity of host ‘192.168.90.164 (192.168.90.164)‘ can‘t be established.

RSA key fingerprint is 89:3c:a6:5c:a3:ee:e4:39:89:23:12:87:66:63:13:21.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added ‘192.168.90.164‘ (RSA) to the list of known hosts.

[email protected]‘s password:

Now try logging into the machine, with "ssh ‘[email protected]‘", and check in:

.ssh/authorized_keys

to make sure we haven‘t added extra keys that you weren‘t expecting.

[[email protected] ~]$ ssh [email protected]

Last login: Wed May 20 17:24:23 2015 from 192.168.90.163

[[email protected] ~]$ logout

Connection to 192.168.90.164 closed.

[[email protected] ~]$

将公钥拷贝到192.168.90.165

[[email protected] ~]$ ssh-copy-id [email protected]

The authenticity of host ‘192.168.90.165 (192.168.90.165)‘ can‘t be established.

RSA key fingerprint is 89:3c:a6:5c:a3:ee:e4:39:89:23:12:87:66:63:13:21.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added ‘192.168.90.165‘ (RSA) to the list of known hosts.

[email protected]‘s password:

Now try logging into the machine, with "ssh ‘[email protected]‘", and check in:

.ssh/authorized_keys

to make sure we haven‘t added extra keys that you weren‘t expecting.

[[email protected] ~]$ ssh [email protected]

Last login: Wed May 20 17:24:19 2015 from 192.168.90.163

[[email protected] ~]$ logout

Connection to 192.168.90.165 closed.

[[email protected] ~]$

下来这一步最重要

[[email protected] ~]$ ssh-agent bash

welcome robin from /etc/profile.d

[[email protected] ~]$ ssh-add

Identity added: /home/robin/.ssh/id_rsa (/home/robin/.ssh/id_rsa)

[[email protected] ~]$ ssh-add -l

2048 ec:d6:ac:e0:57:e5:8a:fb:0e:cf:fc:12:4e:3b:2e:93 /home/robin/.ssh/id_rsa (RSA)

测试效果：

[[email protected] ~]$ ssh -A [email protected]

Last login: Wed May 20 17:27:07 2015 from 192.168.90.96

[[email protected] ~]$ ssh -A 192.168.90.165

Last login: Wed May 20 17:26:49 2015 from 192.168.90.96

[[email protected] ~]$ logout

Connection to 192.168.90.165 closed.

[[email protected] ~]$ logout

Connection to 192.168.90.164 closed.

ssh -A 参数使用示例的相关文章

ssh 的参数 -o + 检查是否是无密码访问

转自:http://blog.chinaunix.net/xmlrpc.php?r=blog/article&uid=29578485&id=5300984 写脚本想检查服务器之间是否建立了公钥实现了无密码访问查找过程中找到了ssh 的一些参数,贴出来,怕下次找不到了这些参数可用在 ssh -o 后面 ,每个参数前面都必须有 -o 脚本如下: ssh -o NumberOfPasswordPrompts=0 -o StrictHostKeyChecking=yes 192.168.61

ssh 命令

ssh命令是 SSH(全称 Secure Shell)是一种加密的网络协议.使用该协议的数据将被加密,如果在传输中间数据泄漏,也可以确保没有人能读取出有用信息.要使用 SSH,目标机器应该安装 SSH 服务端应用程序,因为 SSH 是基于客户-服务模式的. 当你想安全的远程连接到主机,可中间的网络(比如因特网)并不安全,通常这种情况下就会使用 SSH. 安装 SSH 如果碰巧你的机器没装,我们可以手工来安装一下.最简单的方式就是使用 Linux 包管理器. 基于 Debian / Ubuntu
