是否可以將Git SSHKey從一個系統轉移到另一個系統

我對Git非常陌生。我的客戶要求我在我的系統中安裝git，並告訴我要通過ssh密鑰（id_rsa.pub）。我轉移了密鑰並註冊了，之後我們才能夠下載該應用程序。是否可以將Git SSHKey從一個系統轉移到另一個系統

然後我們決定轉到Fedora 14（Linux）。我們再次安裝了git，然後我們再次將密鑰傳輸到服務器中註冊到客戶端。但現在客戶提到我們可以使用相同的密鑰。

是否可以使用相同的密鑰？

我嘗試下面的步驟：（一旦混帳得到安裝在Fedora中。）

ssh-keygen -t rsa -C "[email protected]"（相同的電子郵件ID用作Windows操作系統）
替換所有的副本創建的3個文件3個文件（id_rsa，id_rsa.pub和known_hosts中從Windows安裝更早）
試圖git clone [email protected]:x2.git

，但沒有運氣。

當我嘗試：

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.

有人可以幫助我瞭解和解決這個問題？是否有其他問題鎖定訪問？

在此先感謝。

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

nope連接超時..是否有阻塞？ – Rakesh 2011-12-21 09:14:42

做相同的命令工作，如果你在服務器本身發出它？ – 2011-12-21 09:16:52

ssh私鑰沒有綁定到一臺機器，你可以將它從一臺機器複製到另一臺機器上，並且應該能夠將ssh（並因此使用git）發送到擁有公鑰的服務器。您不必重新創建密鑰並替換副本等，但即使從鍵盤的角度來看，您所做的一切都很好。

你得到的錯誤是ssh: connect to host git.xyz.com port 22: connection timed out fatal這似乎暗示該框無法訪問服務器。

正如@manojlds所提到的，您可以複製ssh密鑰。我親自在開發機器上完成了這項工作。

連接時間似乎是由於ssh-daemon未運行。爲了確保您可以連接到本機，請執行以下診斷

ps -ef | grep sshd

你應該得到

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

如果sshd的運行，仔細檢查你的鑰匙的權限，強行設置爲0700

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

嘗試運行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

然後，您的sshdaemon存在問題，因爲初始握手失敗。一個成功的溝通如下所示：

LocalUser是Lu，而RemoteUser是Ru。

魯$的mkdir的〜/ .ssh

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

usernameOfRu @ ipOfRu的密碼：「輸入遠程系統的密碼」
