tinc-vpn.org/">Tinc is a Virtual Private Network (VPN) software which allows secure communication between networked devices. In this tutorial, we'll go through the step-by-step process of installing Tinc VPN on NetBSD.
To install Tinc, first, update your system's package repositories with the following command:
pkgin update
Once the package repositories are updated, install Tinc by running the following command:
pkgin install tinc
After the installation is complete, you'll see a message similar to this:
===> Installing for tinc-1.1pre17nb2
===> Checking for dependencies for tinc-1.1pre17nb2
===> Installing tinc-1.1pre17nb2
Congratulations! Tinc is now installed on your NetBSD system.
Now that Tinc has been installed, the next step is to configure it for your specific use case.
The main configuration file for Tinc is located at /usr/pkg/etc/tinc/, and is called tinc.conf.
You can use the tinc.init script to start and stop the Tinc daemon. By default, the script is located at /usr/pkg/etc/rc.d/tinc. The following commands can be used to start the Tinc daemon:
/usr/pkg/etc/rc.d/tinc start
Before running Tinc for the first time, you'll need to generate RSA key pairs for each of the devices that will be part of the VPN. To generate a new key pair, run the following command:
tincd -n <vpn-name> -K <device-name>
Replace the <vpn-name> with the name for your VPN, and <device-name> with a unique name for your device. Repeat the command for each device that will be part of the VPN. This will create a public and private key pair for each device, and will store it in the /usr/pkg/etc/tinc/<vpn-name>/hosts/<device-name> directory.
Once the key pairs have been generated, you'll need to configure each device's tinc.conf file. Edit the configuration file for each device that will be part of the VPN and add the following lines:
Name = <device-name>
AddressFamily = ipv4
Interface = tun0 # Replace with your interface name
ConnectTo = <other-device-name>
Replace <device-name> for the name of the device that you are currently configuring, and <other-device-name> with the name of the device that it will connecting to.
In order for the VPN to communicate with devices outside of the VPN, you'll also need to set up network routing. You can do this by adding a few lines to the /etc/rc.conf file:
gateway_enable="YES"
static_routes="<vpn-name>"
route_<vpn-name>="-net <destination-network> <vpn-device-ip-address>"
Replace <vpn-name> in the static_routes line with the name of your VPN, <destination-network> with the destination network that you want to communicate with, and <vpn-device-ip-address> with the IP address of the device that is connected to the VPN.
Once you have finished configuring all the devices and networks, save the Tinc configuration files and restart the Tinc daemon using the following command:
/usr/pkg/etc/rc.d/tinc restart
The Tinc VPN is now ready to use.
In this tutorial, we have learned how to install and configure Tinc VPN on a NetBSD system. With Tinc, you can securely communicate between devices connected to your VPN network.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
