[opensuse] SSHFS

3 Feb 2017

      Skimming the recent threads, I notice that Carlos has discovered SSHFS. ;-)

I do not recall if this was already installed, or if I installed it with 
the Yast installer.  It is in the repositories.

I use it regularly for connectivity between my system and my Android 
device (a Moto E).

The command I use is in this format:

sshfs gerry@xxx.xxx.xxx.xxx: /home/my_local_username/0_moto_e -o 
uid=1000,gid=100,follow_symlinks

to connect wirelessly inside my own LAN.  Of course, I pre-created the 
0_moto_e directory in my home directory.

On the device, I am using the SSHelper app.

The reason for the uid and gid options is because of the way Android 
handles security, and Unison transfers are done using the "fat" boolean 
option (actually, could use just a subset) so that unchanged files do 
not constantly throw up a "properties changed" listing in Unison.

(uid and gid above are the default first user id and default Users group id)

To make certain which uid and gid a User should use in the above 
command, simply run:
cat /etc/passwd | grep your_username

Of course, for SSHelper, you would generate a key:
ssh-keygen -t dsa -f ~/.ssh/id_dsa -N ''

Then transfer it to the device:
ssh-copy-id -i ~/.ssh/id_dsa.pub  -p 2222 xxx.xxx.xxx.xxx

The LAN IP address of the Android device is used where the xxx+ exists.

If you use rsync, you would need to do similar there, or every time 
(probably) you connect the uid or gid can change, giving false change 
flags on the unchanged files.

This allows me to access the device and operate on it as if it is just 
another local drive.

On my main PC, I use Unison, run commands such as
sha256sum *.mp4 > videos.mp4.sha256
on the device, can use anything available in my openSUSE system (CLI or 
GUI) to deal with the device.

Of all the different experiments I have run with openSUSE to Android 
Connectivity, I have found this is, so far, the fastest, most usefull 
and most reliable method for connecting and moving things around.

I have been using the checksums on large videos, and so far have had no 
failures using this method.

All other methods I have tried to date have ended up with some of the 
files changed (files more than a short few seconds long) with errors, 
sometimes even different sizes.  They would then play -- sort of -- in 
openSUSE, but with artifacts and other glitches, sometimes slight, often 
severe.

Why do I know this?  I am busy running all Connectivity experiments I 
can between an unrooted Android device and an openSUSE machine so that I 
can write up an extensive guide to the interoperability.
