是否可以将Git SSH密钥从一个系统转移到另一个系统

标签: git ssh-keys

我对Git很新。 我的客户要求我在我的系统中安装git并告诉我传递ssh密钥(id_rsa.pub)。我转移密钥并注册,之后我们就可以下载应用程序了。

然后我们决定转向Fedora 14(Linux)。我们再次安装了git,我们再次将密钥转移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?

我尝试了以下步骤:(一旦在Fedora中安装了git。)

  1. ssh-keygen -t rsa -C "your_email@youremail.com"(与Windows操作系统上使用的电子邮件ID相同)
  2. 替换了使用3个文件的副本创建的所有3个文件(早先从Windows安装的id_rsa,id_rsa.pub和known_hosts)
  3. 尝试git clone git@git.xyz.com:x2.git
  4. 但没有运气。

    当我尝试:

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

    有人可以帮助我理解和解决这个问题吗? 锁定访问还有其他问题吗?

    提前致谢。

ssh私钥没有绑定到计算机上,您可以将其从一台计算机复制到另一台计算机,并且应该能够ssh(并因此使用git)到具有您的公钥的服务器。您不必重新创建密钥并替换副本等,但从键的角度来看,即使您所做的也很好。

您收到的错误是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。

如上所述@manojlds,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。为确保您可以连接到本机,请运行以下诊断

ps -ef | grep sshd

你应该

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

如果sshd正在运行,请仔细检查密钥的权限并强制设置为0700。

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

如果你

,请尝试运行ssh -v <user>@<host>
ssh -v 192.168.0.150
OpenSSH_5.8p1 Debian-1ubuntu3, OpenSSL 0.9.8o 01 Jun 2010

ssh: connect to host 192.168.0.150 port 22: Connection refused

然后你的sshdaemon出现了问题,因为初始握手失败了。成功的沟通如下:

LocalUser是Lu,RemoteUser是Ru。

Lu $ mkdir~ / .ssh

Lu $ scp usernameOfRu @ ipOfRu:.ssh / * .ssh / *

usernameOfRu @ ipOfRu的密码:“输入远程系统的密码”
