+

+    <p>You're right, for the most part a byte into your Tor relay means a 

+    byte out, and vice versa. But there are a few exceptions:</p>

+

+    <p>If you open your DirPort, then Tor clients will ask you for a copy of 

+    the directory. The request they make (an HTTP GET) is quite small, and the 

+    response is sometimes quite large. This probably accounts for most of the 

+    difference between your "write" byte count and your "read" byte count.</p>

+

+    <p>Another minor exception shows up when you operate as an exit node, and 

+    you read a few bytes from an exit connection (for example, an instant 

+    messaging or ssh connection) and wrap it up into an entire 512 byte cell 

+    for transport through the Tor network.</p>

+    <h3><a class="anchor" href="#Hibernation">Why can I not browse anymore 

+    after limiting bandwidth on my Tor relay?</a>

+

+    <p>The parameters assigned in the <a 

+    href="#LimitTotalBandwidth">AccountingMax</a> and <a 

+    href="#BandwidthShaping">BandwidthRate</a> apply to both client and 

+    relay functions of the Tor process. Thus you may find that you are unable 

+    to browse as soon as your Tor goes into hibernation, signaled by this 

+    entry in the log:</p>

+

+    <pre>Bandwidth soft limit reached; commencing hibernation. No new 

+    connections will be accepted</pre>

+

+    <p>The solution is to run two Tor processes - one relay and one client, 

+    each with its own config. One way to do this (if you are starting from a 

+    working relay setup) is as follows:</p>

+

+    <ul>

+        <li>In the relay Tor torrc file, simply set the SocksPort to 0.</li>

+        <li>Create a new client torrc file from the torrc.sample and ensure 

+        it uses a different log file from the relay. One naming convention 

+        may be torrc.client and torrc.relay.</li>

+        <li>Modify the Tor client and relay startup scripts to include 

+        '-f /path/to/correct/torrc'.</li>

+        <li>In Linux/BSD/OSX, changing the startup scripts to Tor.client 

+        and Tor.relay may make separation of configs easier.</li>
