<strong class="uidshort">Channel</strong>
</pre>
<hr />
<p>A secure tunnel across an SSH <a href="paramiko.Transport-class.html"
class="link">Transport</a>. A Channel is meant to behave like a socket,
and has an API that should be indistinguishable from the python socket
API.</p>
<p>Because SSH2 has a windowing kind of flow control, if you stop reading
data from a Channel and its buffer fills up, the server will be unable to
send you any more data until you read some of it. (This won't affect
other channels on the same transport -- all channels on a single
transport are flow-controlled independently.) Similarly, if the server
isn't reading data you send, calls to <a
href="paramiko.Channel-class.html#send" class="link">send</a> may block,
unless you set a timeout. This is exactly like a normal network socket,
so it shouldn't be too surprising.</p>
