Not sure if this question belongs in this forum but I'll give it a chance.

I'm trying to connect my Ubuntu with GitHub via a proxy so I can clone repositories via the git command.

I've followed the normal steps to add the proxy settings to the .gitconfig file in /var/www/. The settings are visible in the configfile:

[http] proxy = http://PROXYUSR:PROXYPWD@PROXYHOST:PROXYPORT
[https] proxy = http://PROXYUSR:PROXYPWD@PROXYHOST:PROXYPORT

Result when I try to access GitHub:

root@server:/var/www/# git clone https://github.com/CybOXProject/python-cybox.git
Cloning into 'python-cybox'...
fatal: unable to access 'https://github.com/CybOXProject/python-cybox.git/': Received HTTP code 407 from proxy after CONNECT

When running the git clone command a tcpdump reveals that it is trying to connect to our proxy but lacks the authentication method/credentials. This behaviour is substantiated by looking at the logs of the proxy. The connection is denied because it's not authenticating.

xxxx.55728 > servername.domain.http-alt: Flags [P.], cksum 0x1efc (incorrect -> 0xf2a3), seq 111:222, ack 2957, win 275, options [nop,nop,TS val 4130126559 ecr 801030698], length 111: HTTP, length: 111
        CONNECT github.com:443 HTTP/1.1
        Host: github.com:443
        User-Agent: git/2.14.1
        Proxy-Connection: Keep-Alive

An application running on the same server is using the proxy with the same authentication method/credentials with success.

Any suggestions?

Solved. I didn't realise that the following command is needed to force git to send the credentials and authentication method to the proxy:

git config --global http.proxyAuthMethod 'basic'
