是否可以将Git SSHKey从一个系统转移到另一个系统

问题描述：

我对Git非常陌生。我的客户要求我在我的系统中安装git，并告诉我要通过ssh密钥（id_rsa.pub）。我转移了密钥并注册了，之后我们才能够下载该应用程序。是否可以将Git SSHKey从一个系统转移到另一个系统

然后我们决定转到Fedora 14（Linux）。我们再次安装了git，然后我们再次将密钥传输到服务器中注册到客户端。但现在客户提到我们可以使用相同的密钥。

是否可以使用相同的密钥？

我尝试下面的步骤：（一旦混帐得到安装在Fedora中。）

ssh-keygen -t rsa -C "[email protected]"（相同的电子邮件ID用作Windows操作系统）
替换所有的副本创建的3个文件3个文件（id_rsa，id_rsa.pub和known_hosts中从Windows安装更早）
试图git clone [email protected]:x2.git

，但没有运气。

当我尝试：

git clone [email protected]:x2.git 
Cloning into x2... 
ssh: connect to host git.xyz.com port 22: connection timed out 
fatal: The remote end hung up unexpectedly.

有人可以帮助我了解和解决这个问题？是否有其他问题锁定访问？

在此先感谢。

做'telnet git.xyz.com 22'工作？ – 2011-12-21 09:10:57

做相同的命令工作，如果你在服务器本身发出它？ – 2011-12-21 09:16:52

答

ssh私钥没有绑定到一台机器，你可以将它从一台机器复制到另一台机器上，并且应该能够将ssh（并因此使用git）发送到拥有公钥的服务器。您不必重新创建密钥并替换副本等，但即使从键盘的角度来看，您所做的一切都很好。

你得到的错误是ssh: connect to host git.xyz.com port 22: connection timed out fatal这似乎暗示该框无法访问服务器。

正如@manojlds所提到的，您可以复制ssh密钥。我亲自在开发机器上完成了这项工作。

连接时间似乎是由于ssh-daemon未运行。为了确保您可以连接到本机，请执行以下诊断

ps -ef | grep sshd

你应该得到

root  726  1 0 08:07 ?  00:00:00 /usr/sbin/sshd -D

如果sshd的运行，仔细检查你的钥匙的权限，强行设置为0700

cd .ssh 
chmod -R 0700 *  #Read only to the user only

尝试运行ssh -v <user>@<host>，如果你得到

ssh -v 192.168.0.150 
OpenSSH_5.8p1 Debian-1ubuntu3, OpenSSL 0.9.8o 01 Jun 2010

debug1: connect to address 192.168.0.150 port 22: Connection refused 
ssh: connect to host 192.168.0.150 port 22: Connection refused

然后，您的sshdaemon存在问题，因为初始握手失败。一个成功的沟通如下所示：

LocalUser是Lu，而RemoteUser是Ru。

鲁$的mkdir的〜/ .ssh

鲁$ SCP usernameOfRu @ ipOfRu：的.ssh/*的.ssh/*

usernameOfRu @ ipOfRu的密码： “输入远程系统的密码”
