Capturing Git Traffic

Environment

Product version	Fiddler Everywhere 1.0.0 and above
3rd-party tools	GIT, GitHub
Supported OS	macOS, Linux, Windows

Description

I want to capture the traffic generated from the Git source control while making pull & push requests and cloning repositories. How to configure Git to go through the Fiddler Everywhere proxy?

Configuring Git HTTPS Access alongside Fiddler Everywhere Proxy

1. Start your Git Bash terminal with administrative rights.

2. Configure Git (for HTTPS-accessed repositories) to use the Fiddler Everywhere proxy.

   git config --global http.proxy http://127.0.0.1:8866 
   

3. Disable the SSL/TLS verification by setting http.sslVerify to false.

   git config --global http.sslVerify false
   

Setting http.sslVerify to false can help you quickly setup your environment alongside a man-in-the-middle HTTPS proxy. However, its usage is insecure as it will disable the validation of all self-signed certificates. Alternatively, you could install the Fiddler root CA to the certificate chain and specify it with either http.sslCAInfo or http.sslCAPath.

http.sslCAInfo <path-to-CA-file>
// File containing the certificates to verify the peer when fetching or pushing over HTTPS. The `GIT_SSL_CAINFO` environment variable can override it.

http.sslCAPath <path-to-folder-containing-CAs>
// Path containing files with the CA certificates to verify the peer when fetching or pushing over HTTPS. Can be overridden by the `GIT_SSL_CAPATH` environment variable

Checking Git Proxy Configuration

Check the current Git proxy configuration through the following command:

git config --get-regexp http.* 

Reseting Git Proxy Configuration

Reset the Git proxy settings through the following commands:

git config --global --unset http.proxy
git config --global --unset http.sslVerify
