This article is about a software named onioncat, it is available as a package on most Unix and Linux systems. This software allows to create an IPv6 VPN over Tor, with no restrictions on network usage.
First, we need to install onioncat, on OpenBSD:
$ doas pkg_add onioncat
Run a tor hidden service, as explained in one of my previous article, and get the hostname value. If you run multiples hidden services, pick one hostname.
# cat /var/tor/ssh_hidden_service/hostname
g6adq2w15j1eakzr.onion
Now that we have the hostname, we just need to run ocat.
# ocat g6adq2w15j1eakzr.onion
If everything works as expected, a tun interface will be created. With a fe80:: IPv6 address assigned to it, and a fd87:: address.
Your system is now reachable, via Tor, through its IPv6 address starting with fd87:: . It supports every IP protocol. Instead of using torsocks wrapper and .onion hostname, you can use the IPv6 address with any software.
