我支持代理，所以我决定使用corkscrew和ssh配置文件连接到bitbucket。
我的~/.ssh/config文件：
Host bitbucket.org
Hostname altssh.bitbucket.org
User git
IdentityFile ~/.ssh/id_rsa
ProxyCommand /usr/bin/corkscrew <proxy_url> <proxy_port> %h %p
Port 443
足够清楚，我定义了我的代理设置，并通过端口443上的https隧道连接我的ssh连接。
我在测试ssh -vT git@bitbucket.org时似乎工作正常
以下是显示成功连接的完整详细输出：

You can use git or hg to connect to Bitbucket. Shell access is disabled.

但是当我只运行git pull（或任何其他git命令）时，似乎忽略了配置文件。
ssh: Could not resolve hostname bitbucket.org: Name or service not known
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
我的project/.git/config文件已经过检查，看起来不错：
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = git@bitbucket.org:path/to/project.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
我可能在这里遗漏了一些东西，却看不清楚。
为什么在执行ssh -T git@bitbucket.org时ssh连接并且在使用git <command>时失败？
任何帮助将不胜感激。
