Re: tor traffic ratelimiting

You followed in my mis-steps upon setting up my first node.

kB (kilo-byte - the big 'B') does not equal kb (kilo-bit - the little  
'b').  Tor bandwidth limiting is measured in Kilobytes, bandwidth is  
measured in Kilobits.

If you are trying to keep bandwidth burst to 128kb, then you will  
need to set your BandwidthBurst to 16KB.  (16 KB x 8 bits/byte = 128kb)

Along the same line, your BandwithRate should be 8KB if you wish to  
rate limit to 64kb.

Hope this helps!
