http://code.google.com/p/droidsshd is shrink-wrapped Dropbear SSHd install for Android. Will be PITA to build, but for sure great tool to have.

[pfalconMember]

Update: the git repo at http://code.google.com/p/droidsshd misses the res/ directory, so doesn’t build.

There’s for-cyanogen fork at https://github.com/tpruvot/android_external_droidsshd which has it, but it may have more changes than needed.

[pfalconMember]

Ok, code in https://github.com/tpruvot/android_external_droidsshd is pretty dirty per my like, lot of spurious changes. Trying to contact original author of DroidSSHd.

I noticed yesterday, that there is no working open source SSH daemon and the existing ones are little bit crappy. SSHDroid even checks if there is an Ad-blocker installed…

I started working on a reimplementation of a android frontend for Dropbear SSHd: https://gitorious.org/dropdroid-sshd

Its far from working, but expect a working one with minimal functions soon.

[pfalconMember]

Nice, so are you basing on http://code.google.com/p/droidsshd or writing from scratch? In either case, please make it possible to configure full path to dropbear binary which it would use (or, like: use builtin binary, or external binary at the user-specified path). Thanks.

[DominikMember]

I read the code of DroidSSHd but it is a little bit messy and not my style 😀
I forked https://github.com/CyanogenMod/android_external_dropbear and got it compiling.
Currently I am bundling it and it seems to work.

Any news?

There’re some news from the world: http://f-droid.org/forums/topic/sshelper/

[DominikMember]

Ah nice, didn’t knew that one.

I was busy coding a different application (see http://f-droid.org/forums/topic/birthday-adapter/).

SSHelper looks promising. I will stop developing my one and look in their code when I got time.

I’ve been looking for a free (= libre) SSH server, because I wanted it on my Samsung Galaxy S.

SSHelper requires a later version of Android than the device has (2.2); and I was not ready for doing an upgrade of the OS to CyanogenMod or Replicant right now.

So I explored a bit the other options.

As for the open-source nature of DropBear app: they add pre-compiled binaries (dropbear SSH server implementation) into the Android package; which is not very nice for reproducing the build and adapting their work. (But tolerable for me for now.)

See, e.g., the commits in a fork that show this situation:

* add new binaries

* CyanogenMod’s dropbear is included as a git submodule. That way, building new binaries is simply a matter of
invoking a script.

Dominik, the https://gitorious.org/dropdroid-sshd doesn’t work anymore…

[imzMember]

I’ve submitted that fork (which should be buildable from sources) at http://f-droid.org/forums/topic/dropbearserver-joelpets-fork/ .

[imzMember]

(Retagging this thread correctly.)

[DominikMember]

The Link doesn’t work anymore, because I have stop the project.

[imzMember]

DroidSSHd doesn’t include scp or sftp. I could transfer some files with ssh …. ‘cat – > filename’.

I thought one could use Emacs TRAMP to access files on the Android via DroidSSHd, because it knows a lot about how to adapt to the environment on the machine we are connecting to.

But TRAMP failed due to absent “env” on the Android side IIUC — https://bugs.launchpad.net/emacs/+bug/1041474 .

[imzMember]

For now, while there is no scp or SFTP for this SSHd installed on a non-rooted device, one can use plain “ssh” and “cat” to transfer files to the device (and the output of “ls” to assist continuing a partial trnasfer).

I’ve written simple helper scripts for this — https://gitorious.org/rpush-cat or http://repo.or.cz/w/rpush-cat.git:

Usage:

rpush SRC DEST ssh SSH_args..
rpush-continue SRC [–android|–unix] DEST ssh SSH_args..
rpush-into [-c|–continue] FILE REMOTE_PREFIX ssh SSH_args..
