无法在Windows上克隆,但可以从Gitlab服务器在Linux上克隆

Question

我试图通过SSH从远程Gitlab服务器克隆存储库.我使用Gitlab CE version 9.3.9 755bb71与TortoiseGIT version 2.5.0和git (for windows) version 2.14.0

SSH密钥已正确安装,因为我已使用测试身份验证

ssh -vT git@192.168.100.100 -i /path/to/.ssh/key

我使用上面的密钥获得以下消息验证成功

当我在Windows上使用TortoiseGit克隆存储库时,我在客户端上收到以下错误

Cloning into 'C:\path\folder'...
GitLab: Disallowed command
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

在gitlab服务器上,gitlab-shell.log我收到以下警告消息

WARN -- : gitlab-shell: Attempt to execute disallowed command <git upload-pack '/path/to/repo.git'> by user with key key-1.

但是当我尝试git clone使用另一台具有不同SSH密钥的Linux机器时,它是成功的,我gitlab-shell.log在gitlab服务器上收到以下信息消息

INFO -- : gitlab-shell: executing git command <gitaly-upload-pack  {"repository":{"path":"/very/long/path/to/repo.git"},"gl_id":"key-2"}> for user with key key-2.

我花了超过10个小时试图调试一切,我不确定有什么区别或问题究竟在哪里.我也尝试在.gitconfigTortoiseGit的本地文件中添加以下内容,但这并没有改变任何内容.

[remote "origin"]
  uploadpack = git-upload-pack

最后,通过HTTPS克隆相同的存储库工作正常,使用用户名/密码没有任何问题.

Answer 1

注意:我刚刚升级到适用于Windows的Git 2.14.0 ......并且没有一个ssh url正在运行:

> git ls-remote
GitLab: Disallowed command
fatal: Could not read from remote repository.

(origin作为ssh网址)

另一个副作用:git-for-windows/git问题1258

fatal: protocol error: bad line length character: Not

看起来BitBucket看起来argv[0](通常git-upload-pack使用回归git)来确定它是否是允许的命令.

所以我认为这是设计git被拒绝而git-upload-pack不是.

同样在GitLab上出错:gitlab-ce issue 360​​28.
该未决的合并请求 明确地恢复git-xxx它检测到时git xxx命令.

看到 gitlab_shell.rb#parse_cmd(args)

  def parse_cmd(args)
    # Handle Git for Windows 2.14 using "git upload-pack" instead of git-upload-pack
    if args.length == 3 && args.first == 'git'
      @command = "git-#{args[1]}"
      args = [@command, args.last]
    else
      @command = args.first
    end

在Git for Windows端,正在进行修复:请参阅commit 0f33428

还原"git_connect:更喜欢Git的内置素而不是虚线形式"

看起来这个更改(用于修复与本地存储库交互的测试时git-upload-pack不在其中 PATH)在SSH访问中退化.

一个混帐的Windows 2.14.0(2)是在工作和刚刚发布(2017-08-07T11:05:34Z UTC)31分钟前,在此编辑的时间.

原始答案

如果key1与您的相同 /path/to/.ssh/key并且确定了John Doe,那么这应该意味着John Doe无法访问该回购(如此处所示).
检查key2是否与其他用户关联.

如果两个键都引用同一个用户,则更多的是本地配置问题(如本答案中所述).还要检查您的TortoiseGit是否使用与测试中相同的密钥:

set "GIT_COMMAND_SSH=ssh -v"
# launch TortoiseGit from that CMD session

然后,您将看到TortoiseGit在使用ssh url克隆repo时正在使用的内容.您可能需要定义.ssh/config文件.
