GitHub offers a few different ways to connect to the remote repo. I am behind an onerous firewall. All methods also hang except using http (not https).
For example, the JavaHamcrest project offers (anonymously):
- https://github.com/hamcrest/JavaHamcrest.git
- git@github.com:hamcrest/JavaHamcrest.git
- git://github.com/hamcrest/JavaHamcrest.git
You may also try:
- http://github.com/hamcrest/JavaHamcrest.git
Finally, prefix your UNIX command with GIT_TRACE=1 and GIT_CURL_VERBOSE=1, and use Git option --verbose for maximum debug output.
Example: env GIT_TRACE=1 GIT_CURL_VERBOSE=1 git clone --verbose http://github.com/hamcrest/JavaHamcrest.git
