ubuntu – 尝试使用RSA密钥SSH到EC2,获取:不正确的RSA1标识符…权限被拒绝(公钥)

前端之家收集整理的这篇文章主要介绍了ubuntu – 尝试使用RSA密钥SSH到EC2,获取:不正确的RSA1标识符…权限被拒绝(公钥)前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我在Amazon EC2上创建了一个Ubuntu 12.04实例。

我已经下载了PEM文件,并且能够SSH进入实例,没问题。

现在,我想在远程实例上创建一些顾问等等。
他们应该能够使用RSA密钥进入盒子。在EC2机器上,我已经在〜/ home /中设置了几个帐号,并将它们分配给组管理员。我也给自己一个类似的帐户(MyTestAccount)进行测试。这就是我所做的:

我使用key-gen在本地机器上的.ssh目录中创建公钥和私钥(〜/ .ssh):

drwx------  2 peter peter 1024 Sep 14 10:23 .ssh

和里面的文件

-rw-------  1 peter peter 1675 Sep 14 10:23 id_rsa
-rw-------  1 peter peter  394 Sep 14 10:23 id_rsa.pub
-rw-------  1 peter peter  444 Sep 14 00:05 known_hosts

然后我将id_rsa.pub文件SCP我的远程EC2实例,并将其附加到
.ssh / authorized_keys文件在我的远程实例。我的遥控器的权限
.ssh目录:

drwx------ 2 ubuntu ubuntu 4096 Sep 16 16:13 .ssh

和我的authorized_keys文件

-rw-------  1 peter ubuntu  1179 Sep 14 00:05 authorized_keys

接下来,我注销了我的远程实例,并尝试使用新的密钥SSH到远程框。当我发出以下命令时:

peter@ubuntu:~/.ssh$ ssh -vvv MyTestAccount@ec2-XX-XXX-XX-XXX.compute-1.amazonaws.com

我得到以下看来我的私钥有问题吗?有什么建议么?谢谢。

OpenSSH_5.9p1 Debian-5ubuntu1,OpenSSL 1.0.1 14 Mar 2012

debug2: we did not send a packet,disable method

这种情况是正常的,这并不奇怪。
你得到的消息:

debug3: Incorrect RSA1 identifier
debug3: Could not load “/home/user_name/.ssh/id_rsa” as a RSA1 public key

确实没有指出错误
RSA1公钥仅用于已经过时的SSH协议1。如今,SSH协议2大多使用。

在正常的SSH登录过程中,您可能会看到带有ssh -vvv的警告消息。
你可能会感到惊讶,但不用担心,这是正常现象。
