If youre asking about setting up a VPN on Linux,heres a general guide on how to do it:

It seems like you're asking about a VPN service called "zju" on Linux systems. However, "zju" does not appear to be a widely recognized company or term in the context of VPN services. If you're referring to a specific VPN service provided by a company named ZJU, I recommend checking their official website or contacting them directly for accurate information.

1. Install a VPN Client:

   Download and install a VPN client (e.g., netcat or vpnmanager) from a trusted source.

2. Set Up Your Linux System:

   If you're using Linux, ensure your system is up-to-date and has the necessary packages installed.

3. Configure the VPN:

   • Open the VPN client and log in using your public IP address.
   • Configure your IP address to use the ZJU VPN service.

4. Log In:

   Once configured, log in with your public IP address to access the VPN services.
