Nnvpn (No Name VPN) is a VPN core implementation. It permits to create an encrypted virtual network between two Linux hosts.
- Endpoints are TUN devices:
- Cryptographic layer uses OpenSSL library:
The program is intended to be used in a Linux environment and it is tested using the following Linux distributions:
- Ubuntu 22.04.2 LTS (jammy) for ARM
- Ubuntu 22.04.2 LTS (jammy) for x86-64
using, as compiler, one in this list:
- g++ (Ubuntu 11.3.0-1ubuntu1~22.04.1) 11.3.0 (ARM)
- g++ (Ubuntu 11.3.0-1ubuntu1~22.04.1) 11.3.0 (x86-64)
To compile the program, this tools/libraries are necessary:
- a c++ compiler ( with c++20 support);
- automake/autoconf with libtool;
- Create config scripts:
make -f makefile.dist
- launch the configure script:
./configure
- Compile the program:
make
- Install the program and the man page:
sudo make install
- set capabilities ( if "make install" is not performed ):
sudo setcap cap_net_admin=ep src/nnvpn
- This program use a configuration file using LUA syntax, you can find a template in ./data directory. See man page for details.
- You need OpenSSL certificates: the script createCert.pl is provided as example: it will create certificates with default parameters. A passphrase will be asked as input.
- Client machine:
nnvpn -f /home/test/vpn/data/nnvpn.lua
- Server machine:
nnvpn -s -f /home/test/vpn/data/nnvpn.lua
- To test the connectivity, it's possible to use a simple html file:
<!DOCTYPE html>
<html>
<head>
<title>Tvpn test!</title>
</head>
<body>
<p>If you see me, it works!</p>
</body>
</html>
- Copy this code in a file called "index.html" in a test directory in the SERVER machine;
- Having python3 installed, start the test HTTP server using TUN device IP and a free port port. The shell points to the directory containing "index.html":
python3 -m http.server --bind 10.0.0.1 9090
- From the CLIENT machine, we are about to download the test page using curl:
curl -v -L 10.0.0.1:9090
the output, if the test is successful, will be similar to the following:
* Trying 10.0.0.1:9090...
* Connected to 10.0.0.1 (10.0.0.1) port 9090 (#0)
> GET / HTTP/1.1
> Host: 10.0.0.1:9090
> User-Agent: curl/7.81.0
> Accept: */*
>
* Mark bundle as not supporting multiuse
* HTTP 1.0, assume close after body
