Git error: fatal: unable to connect a socket (Invalid argument)

Question

I\'ve got msysGit (Git on Windows) working just fine on my home machine, but at work, where we are behind a Microsoft ISA proxy, I get the following error when I do a git cl

Answer 1

I had the exact same error; but the ~/.gitconfig global config file was the key.

If you have a proxy with authentication you need to put in it:

git config --global http.proxy http://login:password@our-proxy-server:8088

And it just works (with 'git clone http:')

Example of a blog detailing the same setup: GIT clone over HTTP: who knew?

If it still fails in 407, it could be related to a problem with git-fetch losing authentication tokens on the second HTTP GET. A more recent version of libcurl might be needed.

Update January 2011: jbustamovej mentions in his answer (upvoted) his blog post "GitHub Behind Corporate Proxy", which adds this:

It’s important to note that if your login has a backslash, as in domain\login, you must escape the backslash, as in:

git config --global http.proxy http://domain\\\login:password@our-proxy-server:8088
