为准备好做我的第一次感到兴奋,我在我的 cygwin 环境中git push创建了一个别名:PuTTY

alias ssh="/cygdrive/c/PROGRA~2/putty/PUTTY.EXE"

然后调用(当然是在我的工作目录中),正如git community book第 47 页中所述:

git push ssh://mylinuxserver/~winwin/gitrepo master:master

我的兴奋并没有持续很长时间,因为它立即因致命错误而失败:

error: cannot run ssh: No such file or directory
fatal: unable to fork

考虑到我能够从相同的命令行和 shell 实例成功运行,ssh winwin@mylinuxserver我很惊讶收到此错误消息。

知道为什么会发生这种情况以及如何解决这个问题吗?

更新 I:感谢本指南,我发现 PUTTY.EXE 不是在 git 中使用的正确 exe。相反,应该使用PLINK.EXE

该指南还暗示应该使用名为 GIT_SSH 的环境变量让 git 知道如何发挥作用。所以我:

~/sb/ws> export GIT_SSH=/cygdrive/c/PROGRA~2/putty/PLINK.EXE
~/sb/ws> git push ssh://mylinuxserver/~winwin/gitrepo master:master

现在我收到一个不同的错误:

fatal: The remote end hung up unexpectedly

我认为这个进展是正确的,但我仍然不知道如何解决这个问题。任何想法将不胜感激。

更新二:仍在尝试解决这个谜团。这一次我怀疑由于git push没有在任何地方提示输入用户名+密码,身份验证必须在密钥中......所以,我根据这个 howtosshd仔细检查了配置。我发现唯一需要更改的是取消注释行并重新启动服务。在那之后的第一次,确实提示确认服务器的 dss 密钥指纹,我确认将密钥存储在缓存中,但是......问题仍然存在:HostKey /etc/ssh/ssh_host_dsa_key/etc/ssh/sshd_configservice sshd restart$GIT_SSH

fatal: The remote end hung up unexpectedly

额外的想法?

(PuTTY 的注册表现在包含同一服务器的两个键:rsa2@22:mylinuxserverdss@22:mylinuxserver。嗯……我不确定这是什么意思)

更多诊断信息:打字$GIT_SSH -v产生:

你能发现任何可疑的东西吗?

到达那里:到目前为止,我的情况最好的指南:Git、SSH、PuTTY

见解:

  1. $GIT_SSH -agent必须运行一次
  2. PAGEANT.EXE 必须在后台运行(并通过其系统托盘图标将私钥添加到其中!)
  3. 必须使用 PUTTYGEN.EXE 生成公钥/私钥对
  4. dss 不是强制性的,rsa 就足够了。
  5. 更多?(除非$GIT_SSH -2 -C -i C:\\Users\\winwin\\SSH\\private.ppk在没有密码提示的情况下成功,否则甚至尝试都没有意义git push......)

在将公钥从 PuTTY 密钥生成器复制并粘贴到新消息后,响应上述见解 #5 中的命令出现/home/winwin/.ssh/authorized_keysmylinuxserver一条新消息:

Server refused our key

这是一个好兆头...... :) 我想我正在解开这个谜团。

更新三:在 sshd 服务器上更改StrictModesno in后/etc/ssh/sshd_config,我成功地使用$GIT_SSH -2 -C -i C:\\Users\\winwin\\SSH\\private.ppk. 不过,它仍然提示输入用户名(但不提示输入密码)。

git push ssh://mylinuxserver/~winwin/gitrepo master:master但是仍然失败 - 带有相同的错误消息:

fatal: The remote end hung up unexpectedly

疯了吧。

更新 IV: PLINK的-l username参数是关键。git push通过创建一个 1 行 shell 脚本/cygdrive/c/PROGRA~2/putty/PLINK.EXE -l winwin $*并将整个脚本的路径导出到,我设法成功登录$GIT_SSH,但“远程端仍然意外挂断”。

这就是我在客户端(Windows/PuTTY)方面得到的:

~/sb/ws> git push ssh://mylinuxserver/~winwin/gitrepo master:master
Environment:

  LOGNAME=winwin
  HOME=/home/winwin

需要最后的线索...

  1. 是什么bash: mylinuxserver: command not found意思?
  2. 什么在git push试图运行?
  3. 哪个命令?
  4. 在客户端还是 SSH 服务器上?

我觉得通过 Putty 是造成所有这些问题的原因,但不清楚为什么这是必要的 - 如果您使用的是 cygwin,那么您已经内置了 ssh。

我通过 cygwin 通过 ssh 使用 git,没有任何问题。可能是更好的路线?是否有理由加入腻子,或者它是在某个地方的指南中推荐的东西?

使用 plink?您可能必须重新创建为 putty 创建的密钥。

我从未成功地gitPuTTY. 对我而言,进一步的时间投资似乎不能证明投资回报率是合理的,所以我放弃了。
