Win*_*Win 6 git ssh cygwin putty sshd
对于准备好第git push一次做好准备感到兴奋,我PuTTY在我的cygwin环境中创建了一个别名:
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社区书中第47页所述:
git push ssh://mylinuxserver/~winwin/gitrepo master:master
我的兴奋并没有持续很长时间,因为它立刻失败了一个致命的错误:
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.
知道为什么会这样,以及如何解决这个问题？
更新I:感谢本指南,我发现PUTTY.EXE不是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知道如何进行魔术.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
我认为这方面的进展正确,但我仍然不知道如何解决问题.任何想法都将非常感激.
更新II:仍然试图解决这个谜.这次我怀疑,因为git push在任何地方都没有提示用户名+密码,身份验证必须在密钥内......所以,我sshd按照这个方法仔细检查配置.我发现为需要改变的唯一的事情是取消对线HostKey /etc/ssh/ssh_host_dsa_key中/etc/ssh/sshd_config,并重新启动该服务service sshd restart.之后的第一次,$GIT_SSH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:
fatal: The remote end hung up unexpectedly
其他想法？
(PuTTY的注册表现在包含同一服务器的两个键:rsa2@22:mylinuxserver和dss@22:mylinuxserver.嗯......我不确定这意味着什么)

你能发现任何可疑的东西吗？
到达目的地:到目前为止,我的情况最好的指南:Git,SSH,PuTTY.
见解:
$GIT_SSH -agent 必须运行一次$GIT_SSH -2 -C -i C:\\Users\\winwin\\SSH\\private.ppk没有密码提示成功,否则甚至没有意义git push......)复制&粘贴从PuTTY密钥生成的公开密钥来后/home/winwin/.ssh/authorized_keys在mylinuxserver一个新的消息出现了响应于上述见解#5的命令:
Server refused our key
这是一个好兆头...... :)我想我正在努力解决这个谜团.
更新三:改变后StrictModes,以没有在/etc/ssh/sshd_configsshd服务器上,我设法与成功$GIT_SSH -2 -C -i C:\\Users\\winwin\\SSH\\private.ppk.它仍会提示输入用户名(但不提示输入密码).
git push ssh://mylinuxserver/~winwin/gitrepo master:master 然而继续失败 - 使用相同的错误消息:
fatal: The remote end hung up unexpectedly
疯了吧.
更新IV:-l username PLINK 的参数是关键.我设法git push通过创建一个单行shell脚本/cygdrive/c/PROGRA~2/putty/PLINK.EXE -l winwin $*并导出整个脚本的路径成功登录$GIT_SSH,但"远程端仍然意外挂起".
这是我在客户端(Windows/PuTTY)方面得到的:
