DragonFlyBSD's daily snapshots and releases (starting with 3.4) come with
pkg already installed. Upgrades from earlier releases, however, will not have it.
pkg is missing on the system for any reason, it can be quickly bootstrapped without having to build it from source or even having DPorts installed:
pkg-static install -y pkg
1.1. Recommended Steps to Setup
Here, it will be similar to what we have on a FreeBSD system, and we are going to use HTTPS to fetch our packages, and updates - so here we also need an extra package to help us out (
pkg install ca_root_nss
For fresh installations, the file
/usr/local/etc/pkg/repos/df-latest.conf.sample is copied to
/usr/local/etc/pkg/repos/df-latest. The files ending in the ".sample" extension are ignored; pkg(8) only reads files that end in ".conf" and it will read as many as it finds.
DragonflyBSD has 2 packages repositories:
- Avalon (mirror-master.dragonflybsd.org);
- Wolfpond (pkg.wolfpond.org).
We can simply edit the URL used to point to the repositories on
/usr/local/etc/pkg/repos/df-latest and that's it! Remember to use pkg+https:// for Avalon.
After applying all these changes, we update the packages list again and try to check if there's already a new update to apply:
pkg update -f
pkg upgrade -y -f
obfs4proxy DragonflyBSD's Package
Here we can choose to install the latest stable version, like:
pkg install tor obfs4proxy-tor
... or install an alpha release:
pkg install tor-devel obfs4proxy-tor
/usr/local/etc/tor/torrc to run Tor as a Bridge
# Replace "TODO1" with a Tor port of your choice. This port must be externally
# reachable. Avoid port 9001 because it's commonly associated with Tor and
# censors may be scanning the Internet for this port.
ServerTransportPlugin obfs4 exec /usr/local/bin/obfs4proxy
# Replace "TODO2" with an obfs4 port of your choice. This port must be
# externally reachable and must be different from the one specified for ORPort.
# Avoid port 9001 because it's commonly associated with
# Tor and censors may be scanning the Internet for this port.
ServerTransportListenAddr obfs4 0.0.0.0:TODO2
# Local communication port between Tor and obfs4. Always set this to "auto".
# "Ext" means "extended", not "external". Don't try to set a specific port
# number, nor listen on 0.0.0.0.
# Replace "<email@example.com>" with your email address so we can contact you if
# there are problems with your bridge. This is optional but encouraged.
# Pick a nickname that you like for your bridge. This is optional.
Log notice file /var/log/tor/notices.log
Don't forget to change the
Note that both Tor's OR port and its obfs4 port must be reachable. If your bridge is behind a firewall or NAT, make sure to open/forward both ports. You can use our reachability test to see if your obfs4 port is reachable from the Internet.
Are you firewalling your DragonflyBSD? If so, make sure that
obfs4proxy can talk to
tor over the loopback interface - do not forget to allow the ExtORPort.
Here we set
tor to start at boot time and use the setuid feature, in order to bind to lower ports like 443 (the daemon itself will still run as a regular non-privileged user).
echo "tor_setuid=YES" >> /etc/rc.conf
echo "tor_enable=YES" >> /etc/rc.conf
service tor start
5. Monitor your logs
To confirm your bridge is running with no issues, you should see something like this in
[notice] Your Tor server's identity key fingerprint is '<NICKNAME> <FINGERPRINT>'
[notice] Your Tor bridge's hashed identity key fingerprint is '<NICKNAME> <HASHED FINGERPRINT>'
[notice] Registered server transport 'obfs4' at '[::]:46396'
[notice] Tor has successfully opened a circuit. Looks like client functionality is working.
[notice] Bootstrapped 100%: Done
[notice] Now checking whether ORPort <redacted>:3818 is reachable... (this may take up to 20 minutes -- look for log messages indicating success)
[notice] Self-testing indicates your ORPort is reachable from the outside. Excellent. Publishing server descriptor.

If your bridge is now running, check out the post-install notes.
