Validating VPN nodes

Validating VPN nodes

Ensuring Valid VPN Nodes in Linux Kodachi

Have you ever wondered how Linux Kodachi maintains the validity of its VPN nodes, even though they come from different providers? In this post, I will explain in detail the process of validating VPN nodes from various providers that Linux Kodachi uses on the server side. This process is automatically triggered by a cron job.

Each VPN provider has its own method of providing a list of nodes. Some offer compressed ZIP files, others use APIs, and some simply provide an HTML page. These lists often contain invalid nodes (offline VPNs) that should not be included for users. To exclude offline nodes from online ones, you need to develop a solution using your preferred programming language. In my case, I used shell scripting, as I performed this task on a Linux box.

Validating HideMe VPN list:

  • Provider Name: HidemeVPN
  • List type: API
  • Retrieval type: Automatic
  • Website: hide.me
  • Used in Linux Kodachi: Yes
