SSH Daemon Service
|

==================

|
|
|
.. include:: example_header.inc
|

**Video:**
|
|
|
|
I've create a little screencast to show how to create a sshd service and connect to it. It is something like 11
|
|
minutes and not entirely smooth, but gives you a good idea.
|
|
|
|
.. raw:: html
|
|
|
|
<div style="margin-top:10px;">
|
|
<iframe width="800" height="400" src="http://ascii.io/a/2637/raw" frameborder="0"></iframe>
|
|
</div>
|
|
|
|
You can also get this sshd container by using
|
|
::
|
|
|
|
docker pull dhrp/sshd
|
|
|
|
|
|
The password is 'screencast'
