<h1 class="epydoc">Class SFTPServerInterface</h1><p class="nomargin-top"><span class="codelink"><a href="paramiko-pysrc.html#SFTPServerInterface">source code</a></span></p>
<pre class="base-tree">

</pre>
<hr />
<p>This class defines an interface for controlling the behavior of
paramiko when using the <a href="paramiko.SFTPServer-class.html"
class="link">SFTPServer</a> subsystem to provide an SFTP server.</p>
<p>Methods on this class are called from the SFTP session's thread, so
you can block as long as necessary without affecting other sessions (even
other SFTP sessions). However, raising an exception will usually cause
the SFTP session to abruptly end, so you will usually want to catch
exceptions and return an appropriate error code.</p>
<p>All paths are in string form instead of unicode because not all SFTP
clients & servers obey the requirement that paths be encoded in
UTF-8.</p>

<p>Return the canonical form of a path on the server. For example, if
the server's home folder is <code>/home/foo</code>, the path
<code>"../betty"</code> would be canonicalized to
<code>"/home/betty"</code>. Note the obvious security issues:
if you're serving files only from a specific folder, you probably don't
want this method to reveal path names outside that folder.</p>
<p>You may find the python methods in <code>os.path</code> useful,
especially <code>os.path.normpath</code> and

<p>Rename (or move) a file. The SFTP specification implies that this
method can be used to move an existing file into a different folder, and
since there's no other (easy) way to move files via SFTP, it's probably a
good idea to implement "move" in this method too, even for
files that cross disk partition boundaries, if at all possible.</p>
