How to Use a VPN on a VPS to Push to Git

SSH Tunneling

Solving Git Push Issues with VPN on VPS

Working on a project for a security company frequently requires using a VPN to access Git repositories. You might not be able to use the company's VPN on your PC directly, nevertheless, due to certain problems.

Using a VPS with the company's VPN installed can be helpful in certain situations, but it makes Git administration more difficult. It takes time to manually transfer updated files from your PC to the VPS, especially when there are a lot of files involved. This post explains how to push to Git straight from your computer without utilizing the VPN provided by the business.

Command Description
ssh -L 8888:gitserver:22 user@vps Creates an SSH tunnel between your local computer and the VPS by mapping port 8888 to the git server's port 22.
git config --global core.sshCommand 'ssh -p 8888' Sets up Git to utilize a certain SSH command that contains the unique port that the tunnel produced.
paramiko.SSHClient() Uses the Python Paramiko package to initialize an SSH client for SSH connections.
ssh.open_sftp() To enable file transfers, it establishes an SFTP session over an active SSH connection.
sftp.put(local_file, remote_file) Uses SFTP to upload a file from the local computer to the remote server.
git config --global http.proxy http://localhost:3128 Configures Git to route requests through the designated proxy server using an HTTP proxy.
ssh -L 3128:gitserver:80 user@vps Establishes an SSH tunnel that routes your local machine's port 3128 to the git server's port 80.

Gaining Knowledge of and Using VPN Git Push Solutions

Using Git directly on your PC without having to install the company's VPN locally is possible with the scripts that are offered. The first script connects to the VPS and forwards the required ports via SSH tunneling. This lets you use your local workstation to execute Git commands just like if it were connected to the VPN. You can establish a tunnel that forwards port 8888 from your local computer to port 22 on the Git server by executing the command . Next, you set up Git to use this tunnel by setting up . You may clone, commit, and push changes straight from your PC using this way.

Using Python and the Paramiko package, the second script automates file transfers between your PC and the VPS. When a large number of files have changed and manually copying them would be unfeasible, this script comes in handy. The script uses to setup an SSH client and to open an SFTP session. After that, iterating through the local files, it uses to upload them to the remote server. The final script configures the VPS to handle Git traffic through an HTTP proxy. You can perform Git activities as if you were directly connected to the VPN by setting up an SSH tunnel with ssh -L 3128:gitserver:80 user@vps and configuring Git to use this proxy with .

Pushing to Git with SSH Tunnels and VPN

Bash script for establishing SSH tunnel

# Step 1: Connect to your VPS and create an SSH tunnel
ssh -L 8888:gitserver:22 user@vps

# Step 2: Configure your local Git to use the tunnel
git config --global core.sshCommand 'ssh -p 8888'

# Step 3: Clone the repository using the tunnel
git clone ssh://git@localhost:8888/path/to/repo.git

# Now you can push changes from your local machine through the VPS tunnel
cd repo
git add .
git commit -m "Your commit message"
git push

Transferring Files Automatically from PC to VPS

Write a Python script to transfer files automatically.

import paramiko
import os

# SSH and SFTP details
hostname = 'vps'
port = 22
username = 'user'
password = 'password'
local_path = '/path/to/local/files/'
remote_path = '/path/to/remote/directory/'

# Establish SSH connection
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname, port, username, password)

# Establish SFTP connection
sftp = ssh.open_sftp()

# Upload files
for file in os.listdir(local_path):
    local_file = os.path.join(local_path, file)
    remote_file = os.path.join(remote_path, file)
    sftp.put(local_file, remote_file)

# Close connections
sftp.close()
ssh.close()

Using a Proxy to Use Git on a Local Machine

Configuring Git to make advantage of an HTTP proxy

# Step 1: Set up an HTTP proxy on your VPS
ssh -L 3128:gitserver:80 user@vps

# Step 2: Configure Git to use the proxy
git config --global http.proxy http://localhost:3128

# Step 3: Clone the repository using the proxy
git clone http://gitserver/path/to/repo.git

# Now you can push changes from your local machine through the proxy
cd repo
git add .
git commit -m "Your commit message"
git push

Improving Git Workflow Using VPN and Proxy

When pushing to Git with a VPN on a VPS, the security and effectiveness of the connections should also be taken into account. Your SSH connections' security can be greatly increased by using SSH keys rather than passwords. To guarantee that only your machine may access the VPS via SSH, generate an SSH key pair on your local computer and add the public key to the VPS. Furthermore, synchronizing files between your PC and the VPS can be streamlined with programs like rsync, which will cut down on the time spent on manual transfers.

Creating a continuous integration/continuous deployment (CI/CD) pipeline is an additional strategy. You may automate the process of pushing changes to the repository by integrating a continuous integration and delivery (CI/CD) solution such as Jenkins or GitLab CI. This may be set up to push changes to the Git server via the VPS and retrieve updates from your local workstation, saving you time and guaranteeing a productive workflow.

In conclusion, maintaining Git repositories without utilizing the VPN on your PC directly is feasible when you use a VPS that has the company's VPN installed. You can route your Git commands through the VPS and perform smooth operations from your local PC by utilizing SSH tunneling. Efficiency is further increased by building up a CI/CD pipeline and automating file transfers using programs like rsync. These techniques solve the difficulties of handling Git in a restricted network environment while simultaneously ensuring a secure and efficient workflow. They also save time.
