<h2>About TFTPy</h2>
|
|
<p>TFTPy is a pure Python implementation of the
|
|
<a href="http://en.wikipedia.org/wiki/Trivial_File_Transfer_Protocol">Trivial FTP protocol</a>.</p>
|
|
<p>I wrote it because the VoIP company that I work for uses
|
|
TFTP to pull firmware loads for our sets, and at times when this
|
|
doesn't work we use a Windows-based diagnostic tool to troubleshoot
|
|
the connection.</p>
|
|
<p>As all of the computers in my home run some flavour of
|
|
<a href="http://en.wikipedia.org/wiki/Linux">Linux</a> or
|
|
<a href="http://en.wikipedia.org/wiki/Freebsd">FreeBSD</a>,
|
|
this tool wasn't much use to me, so I started one of my own.
|
|
I decided to use <a href="http://www.python.org">Python</a>
|
|
since it's comfortable and available for the platforms that I care
|
|
about, and was surprised to not find a pre-existing TFTP library for
|
|
it. So, I wrote one, and here it is. It's not 1.0 yet, but
|
|
downloading is production-ready IMHO, as some of the people using it
|
|
tell me.</p>
|
|

|
|
<h2>Features</h2>
|
|
<p>At this time, it supports the following RFCs:
|
|
<ul>
|
|
<li>
|
|
<a href="http://www.faqs.org/rfcs/rfc1350.html">1350</a>
|
|
The TFTP Protocol, revision 2 (downloads only, octet mode only)
|
|
</li>
|
|
<li>
|
|
<a href="http://www.faqs.org/rfcs/rfc2347.html">2347</a>
|
|
TFTP Option Extension
|
|
</li>
|
|
<li>
|
|
<a href="http://www.faqs.org/rfcs/rfc2348.html">2348</a>
|
|
TFTP Blocksize Option
|
|
</li>
|
|
<li>
|
|
<a href="http://www.faqs.org/rfcs/rfc2349.html">2349</a>
|
|
TFTP Timeout Interval and Transfer Size Options (just the
|
|
tsize option right now)
|
|
</li>
|
|
</ul>
|
|
</p>

|
|
<h2>Future Plans</h2>
|
|
<p>I do have plans for this code before a 1.0 release, including the
|
|
following:
|
|
<ul>
|
|
<li>Complete overhaul of the internal state machine.</li>
|
|
<li>Full RFC 1350 compliance, including netascii mode (I could
|
|
care less about "mail" mode), and uploads (uploads are
|
|
experimental right now and are on the "upload-patch" branch on
|
|
Github).</li>
|
|
<li>Symmetric UDP support. I don't know of an RFC for this but
|
|
it's a no-brainer for NAT traversal. In this mode the server
|
|
should always respond on the port that the RRQ was sent to, so
|
|
stateful firewalls will permit the response.</li>
|
|
<li>Documentation!</li>
|
|
</ul>
|
|
</p>
|
|

|
|
<h2>The Code</h2>
|
|
<p>You can find the latest release at the SourceForge
|
|
<a href="http://www.sf.net/projects/tftpy/">Project Page</a>, as a
|
|
source tarball. It should also be in <a
|
|
href="http://pypi.python.org/pypi">PyPi</a>, so you can use
|
|
easy_install if you prefer.</p>
|
|
|
|
<p>The latest code though is always on the master branch
|
|
in <a href="http://github.com">Github</a>. I did use SVN in
|
|
SourceForge for a while, but after discovering Git I couldn't go back.
|
|
To clone the repository, run the following command using git
|
|
<pre>
|
|
git clone git://github.com/msoulier/tftpy.git
|
|
</pre>
|
|
Patches welcome, even if I can't guarantee response time. You can
|
|
of course send me the url of a public git repository to pull from
|
|
as well.</p>
|
|
|
|
<p>The Github project page is <a
|
|
href="http://github.com/msoulier/tftpy/tree/master">right
|
|
here</a>.</p>
|
|
</p>
|
|
|
|
<a name="support" />
|
|
<h2>Support</h2>
|
|
<p>SourceForge doesn't make the mailing list easy to find, so
|
|
<a href="https://lists.sourceforge.net/lists/listinfo/tftpy-general">here
|
|
is a direct link</a> if you'd like to join.</p>
|
|
<p>Feel free to <a href="mailto:msoulier@digitaltorque.ca">email
|
|
me</a> with any questions, or contact me through github. I'm also
|
|
"msoulier" in <a href="http://identi.ca">identi.ca</a>.</p>
