`/sbin/ip rule add from all fwmark 0x1 lookup $VPNUSER`: this will add a routing rule for the lookup table "transmission", which we will make in the next sectionĨ. ` = 0`: if this doesn't exist yet, create itħ. This will come from the iptables mangling rulesģ. `/bin/grep -c 0x1`: find anything with the 0x1 bit set. `/sbin/ip rule list`: list all of the ip routing rulesĢ. if `/sbin/ip rule list | /bin/grep -c 0x1` = 0 : This will make sure that the masking rule is not added twiceġ. `/usr/bin/tail -n1`: Multiple ip's might show up. `/bin/egrep -o '()'`: There will probably be a netmask. Run this on the command line for the outputĢ. `/sbin/ifconfig tun0`: run ifconfig over tun0. If this is wrong, the default routing will be wrong and you will not be able to get online.**ġ. The `GATEWAYIP=`: This should be the **ip address** that gets assigned via tun0. `VPNIF="tun0"` and `VPNUSER="transmission"`: sets variablesĥ. This is something you have to configure yourself.Ĥ. `/usr/bin/nmcli con up NordVPN`: this will turn on a connection called NordVPN. Must exist within the /usr/bin directory due to how drives get mounted.Ĭode: Select all sudo chmod 766 /usr/bin/safe_transmission.shĢ. Will get executed before the transmission-daemon service starts. Remember that the rvice simply calls the shell script. The systemctl enable command but I am not entirely sure.**Ĭreate the /usr/bin/safe_transmission.sh shell script **NOTE: I assume that you need to be in the /lib/systemd/system folder to run The next step is to make sure that systemctl knows to start the script. `Wants=network-online.target`: this will make sure that the network is up and active `rvice`: probably not needed but doesn't hurtģ. `network-online.target`: ensures that networking is up and activeģ. `network.target`: the very lowest level of networking that guarantees that networking is on but not up (eth0 probably doesn't exist)Ģ. `After=network.target network-online.target`ġ. `User=root`: this will run the script as root userĢ. There are three important things to note here:ġ. Set up scripts to run before starting transmissionĭescription=Setup the VPN and routing for the transmission userĪfter=network.target network-online.target rvice Set up the startup scripts to run transmission as the userĤ. Something like Deluge can sort of run listen only to tun0, but it doesn't workģ. What this does not do is run off of a single networking interface. It is very fast, lightweight, has a remote option,Ĭomes with a web server, and is entirely written in C++ so it runs without an This section will show you how to install and configure transmission. This guide does not get into the specifics of how to configure and set it up but other guides do. A VPN connection called NordVPN (anything really but this guide assumes a connection that you create in network manager called NordVPN). A kernel with iptables, the mangle operator, and routingĤ. I tried others and they simply didn't work.ģ. The configuration requires the following:ġ. This might be a bit too advanced for some users but hopefully this is going to Torrent server over a VPN from bare metal and go through each script in detail. This document is going to describe how to configure and set up a RPi 3 to run a The RPi kernel team hasĭone an excellent job at making this as simple as possible. Lastly, the kernel setup for iptables is non-trivial. Something using and interpreter for speed improvements and ram limitations. That users will probably want to use a bare mettle solution rather than Pi users will find that the 1GB ram limit is quite restrictive. Getting this to work is a tricky problem for a few reasons. Platform, I can only express the sheer joy I have at making this work. Rpi3 kernel is spectacular and makes a lot of this possible, particularly with Like to especially thank the kernel team at the raspberry pi organization. This document will describe how to safely torrent on a Rpi3 using a VPN and This will work with the latest build of Jessey. I didn't have to recompile the kernel to get iptables to work, which was awesome. This is fairly complex so I included a markdown file describing exactly what I did to make using transmission to torrent over a VPN work.įeel free to provide feedback for the document.īTW, I have to give a huge shoutout and thank you to the kernel team. This includes a kill switch using ip tables. I wanted to provide the means to use the raspberry pi 3 as a transmission server over a VPN.
