all, I encountered a problem about git on github on my Ubuntu. I have configured a proxy setting by git config --global http.proxy proxyserver:port But when i type git clone git@github.com:myusername/example.git , i got the following error: ssh: connect to host github.com port 22: Connection timed out fatal: The remote end hung up unexpectedly what should i do? Thanks Steven

    You're attempting to connect with `ssh`, which does not use the HTTP proxy settings. You may need to use an HTTP or HTTPS URL on Github. – Greg Hewgill Sep 04 '13 at 03:37

  • I use the https url to clone the repo, and it work. – FlurryWInd Sep 04 '13 at 13:18

I follow the steps below to access git respositories from behind a corporate proxy. This method works for git repositories using git URLs like "git://something.git"; for git repositories using http URLs like "http://something.git" use the accepted answer for this link instead.

This version uses corkscrew and sets a username and password required by the proxy.

Install corkscrew (Ubuntu)

sudo apt-get install corkscrew

Create credentials file containing your proxy username and password

echo "username:password" > ~/.corkscrew-auth

In my case the credentials look like this 

domain\username:password

Secure auth file

chmod 600 ~/.corkscrew-auth

Create corkscrew wrapper script ~/scripts/corkscrew.wrapper 

#!/bin/sh
exec corkscrew PROXY_IP_ADDRESS PROXY_PORT $* ~/.corkscrew-auth

Make the script executable

chmod +x ~/scripts/corkscrew.wrapper

Configure git

git config --global core.gitproxy ~/scripts/corkscrew.wrapper

Test if you can clone a repository 

git init
git clone git://SOME_GIT_REPOSITORY_ADDRESS

In case you want to clean the git configuration you just made 

git config --global --unset core.gitproxy

Step 1 : Install corkscrew

$ sudo apt-get install corkscrew

Step 2 : Write a script named git-proxy.sh and add the following

#!/bin/sh

exec corkscrew <name of proxy server> <port> $*

# <name_of_proxy_server> and <port> are the ip address and port of the server
# e.g. exec corkscrew 192.168.0.1 808 $*

Step 3 : Make the script executable

$ chmod +x git-proxy.sh

Step 4 : Set up the proxy command for GIT by setting the environment variable

$ export GIT_PROXY_COMMAND="/<path>/git-proxy.sh"

Now use the git commands,such as

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
