GitHub Windows client behind proxy

I'm trying to get the GitHub client for Windows working. I am on a corporate Win 7 x64 computer behind a corporate proxy and firewall. Following various other posts and experimenting with multiple combinations of environment variables and config variables I have found the only way to get cloning and push updates to work is by using the HTTPS_PROXY environment variable, including my full corporate domain user ID and password.

This is unacceptable from a security standpoint. Is there any other way to get this to work?

Additional notes:

The following worked:

• Add an environment variable called HTTPS_PROXY with the value http://[domain]\[userid]:[password]@someproxy.mycorp.com:8080

The following did not work:

• Omitting user id and password from HTTPS_PROXY variable
• Using an environment variable called HTTP_PROXY (no S)
• Adding the http.proxy variable to the global config file (.gitconfig)
• Adding the https.proxy variable to the global config file

In all cases, the GitHub client still does not recognize the proxy: The content of the file TheLog.txt always shows the following on startup:

[time]|INFO|thread:4|GitHub.Helpers.StartupLogger|Proxy information: (None)
[time]|INFO|thread:4|GitHub.Helpers.StartupLogger|Couldn't fetch creds for proxy

And is followed by the output of several failed proxy authentication attempts, all of which indicate "Credentials are missing."

Solution 1:

Add these entries to your '.gitconfig' file in your user directory (go to %USERPROFILE%):

[http]
    proxy = http://<proxy address>:<proxy port>

[https]
    proxy = https://<proxy address>:<proxy port>

And if you don't want to store your password in plaintext, I would use a local proxy forwarder like CNTLM which allows you to direct all traffic through it and can store the passwords hashed.

Unlike the original question, if you don't care if your password is in plain text add these:

[http]
    proxy = http://<username>:<password>@<proxy address>:<proxy port>

[https]
    proxy = https://<username>:<password>@<proxy address>:<proxy port>

Solution 2:

Tried everything of above - and didn't succeed, only thing that helped me is CNTLM - http://cntlm.sourceforge.net/.

Install it and run cntlm -H, than authenticate to corp proxy, edit cntlm.ini file with the output of cntlm, restart the windows service. Update .gitconfig with:

[https] proxy = localhost:3128
[http] proxy = localhost:3128

Now cntlm will do all the authentication, and you'll be able to use GitHub(and Dropbox, btw) behind the corp proxy. At least until next password change :) (than do cntlm -H stuff again)

Solution 3:

I was able to make GitHub Shell to work with our corporate proxy. I'm starting GitHub Shell and execute following command:

export http_proxy=http://<username>:<password>@<corporate proxy>:3128

I would really like to make GUI to work too. But I don't want to set Windows global environment variable which contains my corporate credential information.

Strangely GitHub GUI Client is able to connect to GitHub for user authentication, but only problem is with cloning, pulling and pushing projects from and into GitHub. It seems like the problem is with git implementation. I was able to configure git to run through our proxy without putting my credentials in the git global settings and it was asking for my credentials while performing pull or push requests. But that was working only in Git Shell.

Solution 4:

If you’re using GitHub for Windows in a corporate, chances are high that you’re behind a big bad Corporate Firewall/Proxy. GitHub for Windows doesn’t yet have the proxy parameters in its GUI for setting Options.

To configure GitHub for Windows to use your corporate proxy, edit the .gitconfig file typically found at C:\Users\.gitconfig or C:\Documents & Settings\.gitconfig

Close GitHub for Windows; In .gitconfig, just add

[https] proxy = proxy.yourcompany.com:port
