<h1>SimpleSSHD</h1>
|
|
|
|
|
|
|
|
|
|
<p>SimpleSSHD is an SSH2 server based on dropbear that supports scp,
|
|
|
|
|
sftp, and rsync. It only supports public-key based authentication (no
|
|
|
|
|
password/interactive auth). It does not use root, which means it must
|
|
|
|
|
listen on a port over 1024 (defaults to port 2222).</p>
|
|
|

|
<h2>Quick start</h2>
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
<li> Install SimpleSSHD.
|
|
|
|
|
<li> Make a directory <tt>/sdcard/ssh</tt>, and put an
|
|
|
|
|
<tt>authorized_keys</tt> file in that directory.
|
|
|
|
|
<li> On any computer which will connect to your Android device, set the
|
|
|
|
|
port to 2222. With OpenSSH, this can be done by putting these lines in
|
|
|
|
|
<tt>~/.ssh/config</tt>:
|
|
|
|
|
<pre>
|
|
|
|
|
Host myphone
|
|
|
|
|
Port 2222
|
|
|
|
|
</pre>
|
|
|
|
|
<li> Launch SimpleSSHD, and in Settings enable "Start on Boot", and
|
|
|
|
|
manually start it for the first time.
|
|
|
|
|
<li> You might want to put a <tt>.profile</tt> in <tt>/sdcard/ssh</tt>,
|
|
|
|
|
too.
|
|
|
|
|
</ul>
|
|
|
|
|
|
|
|
|
|
<p>Voila! You can use ssh/scp/sftp/rsync to talk to your Android device!</p>

<h2>Configuration</h2>
|
2014-12-22 14:06:47 +00:00
|
|
|
|
|
|
|
|
<p>There are three directory settings that are important for SimpleSSHD.</p>
|
|
|
|
|
|
|
|
|
|
<p>The first is the path for general dropbear files, which defaults to
|
|
|
|
|
<tt>/sdcard/ssh</tt>. Most importantly, this is where
|
|
|
|
|
<tt>authorized_keys</tt> is found. It is also where host keys wind up
|
|
|
|
|
(they are created on demand), and where temporary files go.</p>
|
|
|
|
|
|
|
|
|
|
<p>Next is the path to the login shell. The default Android shell is
|
|
|
|
|
<tt>/system/bin/sh</tt>, but you may prefer to use the one that come with
|
|
|
|
|
busybox or whatever.</p>
|
|
|
|
|
|
|
|
|
|
<p>Finally is the path for the home directory, which also defaults to
|
|
|
|
|
<tt>/sdcard/ssh</tt>. This is where your ssh session starts out, and is
|
|
|
|
|
where <tt>.profile</tt> will be found if it is present.</p>
|
|
|
|
|
|
|
|
|
|
<p>There is also a place where you can put commandline options for
|
|
|
|
|
dropbear server. The options which are hardcoded are: <tt>-R -F -p
|
|
|
|
|
:portno</tt>. You can use <tt>\</tt> or <tt>"</tt> to escape characters
|
|
|
|
|
in this commandline.</p>

<h2>About</h2>

|
|
|
|
|
|
|
|
<p>SimpleSSHD is built using parts from open source projects: dropbear
|
|
|
|
|
server, openssh (for scp and sftp-server), and rsync. Those projects in
|
|
|
|
|
turn are based on other projects. A lot of people's work is represented
|
|
|
|
|
here, and very little of my own.</p>
|
|
|
|
|
|
|
|
|
|
<p>But if you find bugs/infelicities, it's probably my fault, so email
|
|
|
|
|
me:<br>

|
|
|
|
|

|
|
|
|
<p>Here is the source. If you use this, email me and I'll make sure you
|
|
|
|
|
get the latest:
