Installing the scp module via pip (in stash)

FarmerPaco

Has anyone tried this yet?
I know paramiko is bundled in.
Has anyone successfully install scp?

JonB

scp is "built in" to stash.

scp LOCAL_FILE USER@REMOTE_HOST:/PATH

FarmerPaco

@JonB Yes, it is. I use scp in stash, but was hoping to be able to call scp from inside a python3 script.
Something like this:

from paramiko import SSHClient
from scp import SCPClient

ssh = SSHClient()
ssh.load_system_host_keys()
ssh.connect('example.com')

with SCPClient(ssh.get_transport()) as scp:
    scp.put('test.txt', 'test2.txt')
    scp.get('test2.txt')

I know there is an scp python module:
python scp module

Can I call a Stash command from a python3 file to run scp from stash?
Sorry if I am not making sense.
Thank you again, since I feel like I keep asking you questions.

@FarmerPaco, if it helps, this is not exactly scp, but does the same thing:

#coding: utf-8
import paramiko

s = paramiko.SSHClient()
s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
s.connect("<ip>", port, username='...', password='...', timeout=4)
sftp = s.open_sftp()

sftp.mkdir(remote_dir) # if needed
sftp.put(local_path, remote_path)
s.close()

JonB

Stash let's you import it, and run commands via script. Or you could add the stash/bin path to sys.path, and then run_py the module.

FarmerPaco

@mikael thanks for this. I will check it out later, but it looks like something I should know.
I am assuming that in s.connect the port is 22 for sftp.
Thanks for the pointer.

FarmerPaco

@JonB thanks for pointing out my options. Will probably try installing the ssh python module first.
Normally when I think of ssh I think of Bash, and since Stash (from what I read) is really just emulating a shell, I wasn’t sure if that would get in the way.
I guess there is only one way to find out.
Again, thanks.

JonB

Paramiko comes preinstalled, which is what stash uses internally. You can read the stash/bin/scp.py and see what it does, it is not complicated.

Trying to install any modules not made for pythonista is going to result in disappointment.

cvp

@JonB Trying to install any modules not made for pythonista is going to result in disappointment. is so true but I like your humor 😂

FarmerPaco

@JonB Thanks again for your time
I’m going to install PyDrive on my Pi zero to familiarize myself with the normal process so I can debug where along the process my pythonista install is failing.

I did check the site packages and saw the Stash running 2.7 installs a more updated version of pyasn1 (v. 2.1) where as stash runing at 3.6 installs an earlier version of pyasn1 (v.1.7). This seemed strange.

Thanks again for your feedback. I will finish a PyDrive install on Rasbian (debian) which should be straightforward and then see where I am going wrong on Pythonista.
I will also check stash/bin/scp.py

JonB

Did you post your traceback for pydrive issues?

JonB

BTW, iirc, monkeylord in stash has the capability to "mount" Google drive folder.

The mount-command currently only supports dropbox, ftp, zipfiles and other directories. I am thinking about rewriting it to use pyfilesystem2 instead, but this may still take a while.

Interesting... Are you using StaSh version 0.7.2? I recently changed pip to respect the python version when installing new packages, but pyasn1 should work for both... Also, are you sure about the version of pyasn1? According to pypi the most recent version is 0.4.5.

FarmerPaco

@bennr01 I am not running 7.2. Running 7.1 and that might be part of my problem. Will update shortly.

Regarding pyasn1, versions 2.1 to 4.2 were released in 2017.

I believe I am looking at the version of pyasn1 correctly. I only did so because in the original guide I was following @JonB specifically installed a version of pyasn1 after PyDrive. I wanted to make sure my version was the same or higher.

I looked in: /site-packages-2/pyasn1/init.py

version = '0.2.1'

Then I looked in: /site-packages-3/pyasn1/init.py

version = '0.1.7'

Not sure why these would be different, or why the version in my python3 would be an earlier version. I am thinking to delete these packages from PyDrive and dependencies, update stash and then reinstall with pip.

Also plan to do a PyDrive on my raspberry pi today and compare the files.
I am still new to this stuff but what to understand better what’s happening under the hood.

FarmerPaco

@bennr01 just want to confirm that installing PyDrive via pip on raspbian downloads pyasn1 0.4.5

This is not the same with pip in stash 7.1.

But I honestly don’t know how much it matters.

FarmerPaco

Just to follow up on this matter. After struggling with PyDrive in pythonista for a while with resulting errors, I often to just go ahead and try the Google Drive API.

There is a super simple tutorial in codelabs:
https://codelabs.developers.google.com/codelabs/gsuite-apis-intro/#0

Everything installs nicely and runs well.It even lets you complete the authentication in a separate browser if need be. I did the authentication on my raspberry pi and scped the secrets.jason and since then it works perfectly.

Just in case anyone wants to access and G suite files, you should know that pip in stash running in python3 nicely installs google-api-python-client and oauth2client in the site-packages-3 (which is all you need for Google Drive API).
