Re: [tor-relays] Raspberry Pi - Relay Setup

[12xBTM <12xbtm@xxxxxxxxx>]

Let me add to this since I have a raspberry pi 2 tor relay:

First off, I run debian jessie on my pi2, but pi2 supports debian 
wheezy. Make sure you harden your SSH to attack. You'll want to dedicate 
as little ram to graphics as possible. You also want to have 
AvoidDiskWrites and CPUNums in your torrc file as well, the details of 
which can be found in the tor debian manual.

As for performance: My stock Pi2 averages about 30-40% load when it 
bursts to 25Mbit/s, which saturates the connection. Thus, scaling 
somewhat linearly, a Pi2 overclocked could probably handle a 
50-100Mbit/s connection.  But you'll want to monitor things closely in 
the beginning since there isn't much wiggly room on the Pi2. For 
example, my image of debian jessie had a irqbalance service that had a 
memory leak and was eating all the ram, which plagued my stability in 
the first few weeks.

Also, you want a quality power supply, and, if it's a hot environment 
and/or overclocking, a heat sink. Security and stability are the most 
important, and the Pi2 can easily handle a residential connection as a 
non-exit node, I only wish I had the connections to utilize my hardware.
