Tinc install instructions for Linux:
We will be using apt to install development tools and dependencies before we download the source code of tinc.
First we will download essential packages to compile tinc as a sudo user:
$ sudo apt install build-essential automake libssl-dev liblzo2-dev libbz2-dev zlib1g-dev libncurses5-dev libreadline-dev
Navigate into a tmp folder:
$ cd /tmp
Download tinc 1.1 with wget and uncompress the downloaded item to a folder with tar:
$ wget https://www.tinc-vpn.org/packages/tinc-1.1pre17.tar.gz
$ tar xvf tinc-1.1pre17.tar.gz
Navigate into the folder and run the configure file to set tinc up:
$ cd tinc-1.1pre17
$ ./configure
Install tinc:
$ make
$ sudo make install
Once installed, create a configuration directory. All configurations of tinc will happen in this folder. Using tinc subcommands (like invite / join), result in changes to the files in this folder.
$ sudo mkdir -p /usr/local/etc/tinc/
The tinc executable is installed in:
$ /usr/local/sbin/tinc
This means that you can only run tinc as sudo, since sbin directory saves binary executables that can be ran only by sudo (s+bin).
