通过ssh tunnel让git使用代理

在墙内有时候签个东西实在是慢得不可想象

wangjl@wangjl-laptop ~/workspace/test $ git clone git://git.savannah.gnu.org/gnulib.git
Cloning into gnulib...
remote: Counting objects: 120258, done.
remote: Compressing objects: 100% (19913/19913), done.
Rceiving objects:   4% (5096/120258), 1.24 MiB | 3 KiB/s


google到了这篇文章（http://www.vpsee.com/2011/07/how-to-use-git-through-a-http-proxy/），说git只有用HTTP方式的时候能使用代理，其他就只能找使用socat这样的代理软件了，connect-proxy大概也可以……

但我琢磨我这样可能更标准也更简单一点：

1、查到服务器ip

wangjl@wangjl-laptop ~/workspace/test $ host git.savannah.gnu.org
git.savannah.gnu.org has address 140.186.70.72

2、建立ssh通道

ssh  -L9418:140.186.70.72:9418  -i  ~/.ssh/vpsee xxx.xxx.xxx.xxx  -pxxxx  （呵呵，我也是vpsee的客户）

3、修改hosts文件
echo 127.0.0.1    git.savannah.gnu.org>>/etc/hosts

效果：


wangjl@wangjl-laptop ~/workspace/test $ sudo emerge -av gnulib

These are the packages that would be merged, in order:

vpsee的机器还是挺快的
