Tunnel Broker provided by HE.net Running at User Space for Systemd.
Requires iproute2 and gcc. Tested and used on an OpenVZ VPS running Debian 8.
OpenVZ VPS do not allow 6in4 tunnel at kernel space. To use an OpenVZ VPS as an HE.net tunnel broker end point, some tricks are needed, as provided in this repo.
Clone first.
git clone https://github.com/Blaok/tb-userspace
cd tb-userspace
Make and install.
make
sudo make install
Edit configuration(s) accordingly.
Do not use the name example.conf as it would be removed when make uninstall.
Configuration files are located at /etc/tb-userspace by default.
Create something like /etc/tb-userspace/someconfig.conf.
Then
sudo systemctl start tb@someconfig
sudo systemctl enable tb@someconfig
The makefile will add a 10 tb entry to /etc/iproute/rt_tables when make install and remove any 10 tb line when make uninstall. Make sure there is no conflict with existing rt_tables.
The tb-userspace source code is obtained from https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/tb-tun/tb-tun_r18.tar.gz. I commented out line 106 and 142 to avoid unnecessary debugging information. Besides, I renamed it from tb_userspace.c to tb-userspace.c.
