Configure Git to use a proxy

##In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

git config --global http.proxy http://proxyUsername:[email protected]:port

Or for a specific domain, something like:

git config --global http.https://domain.com.proxy http://proxyUsername:[email protected]:port
git config --global http.https://domain.com.sslVerify false

See also the git-config documentation, especially the following sections if you're having HTTPS/SSL issues

http.sslVerify
http.sslCAInfo
http.sslCAPath
http.sslCert
http.sslKey
http.sslCertPasswordProtected

In Detail

Configure the proxy

You can configure these globally in your user ~/.gitconfig file using the --global switch, or local to a repository in its .git/config file.

Setting a global proxy

Configure a global proxy if all access to all repos require this proxy

git config --global http.proxy http://proxyUsername:[email protected]:port

URL specific proxy

If you wish to specify that a proxy should be used for just some URLs that specify the URL as a git config subsection using http.<url>.key notation:

git config --global http.https://domain.com.proxy http://proxyUsername:[email protected]:port

Which will result in the following in the ~/.gitconfig file:

[http]
[http "https://domain.com"]
	proxy = http://proxyUsername:[email protected]:port

Handle subsequent SSL protocol errors

If you're still having trouble cloning or fetching and are now getting an unable to access 'https://...': Unknown SSL protocol error in connection to ...:443 then you may decide to switch off SSL verification for the single operation by using the -c http.sslVerify=false option

git -c http.sslVerify=false clone https://domain.com/path/to/git

Once cloned, you may decide set this for just this cloned repository's .git/config by doing. Notice the absence of the --global

git config http.sslVerify false

If you choose to make it global then limit it to a URL using the http.<url>.sslVerify notation:

git config --global http.https://domain.com.sslVerify false

Which will result in the following in the ~/.gitconfig file:

[http]
[http "https://domain.com"]
	proxy = http://proxyUsername:[email protected]:port
	sslVerify = false

Show current configuration

To show the current configuration of all http sections

git config --global --get-regexp http.*

If you are in a locally cloned repository folder then you drop the --global and see all current config:

git config --get-regexp http.*

Unset a proxy or SSL verification

Use the --unset flag to remove configuration being specific about the property -- for example whether it was http.proxy or http.<url>.proxy. Consider using any of the following:

git config --global --unset http.proxy
git config --global --unset http.https://domain.com.proxy

git config --global --unset http.sslVerify
git config --global --unset http.https://domain.com.sslVerify
