I am testing a piece of hardware which hosts an ftp server. I connect to the server in order to configure the hardware in question.
My test environment is written in Python 3.
To start the ftp server, I need to launch a special proprietary terminal application on my pc. I must use this software as far as I know and I have no help files for it. I do however know how to use it to launch the ftp server and that's all I need it for.
When I start this app, I go to the menu and open a dialog where I select the com port/speed the hardware is connected to. I then enter the command to launch the ftp server in a console like window within the application. I am then prompted for the admin code for the hardware, which I enter. When I'm finished configuring the device, I issue a command to restart the hardware's software.
In order for me to fully automate my tests, I need to remove the manual starting of this ftp server for each test.
As far as I know, I have two options:
Windows GUI automation
Save the stream of data sent on the com port when using this application.
I've tried to find an GUI automater but pywinauto isn't supporting Python 3. Any other options here which I should look at?
Any suggestions on how I can monitor the com port in question and save the traffic on it?
Thanks,
Barry
Have you looked at pySerial? It's been a few years since I've used it but it was quite good at handling RS-232 communications and it looks like it's compatible with Python 3.x.
Sikuli might provide the kind of GUI automation you need.
I was also able to solve this using WScript, but pySerial was the preferred solution.

I want to capture traffic of a particular Android device using a Python script. I am doing the same thing for a laptop using "pyshark" that monitors the real-time traffic of laptop for a specific time and then creates a pcap file for it. I want to do the same thing for my Android device. I have tried Tcpdump, scapy and packetsniffer but nothing helped me in capturing the traffic of my Android device.
Ideally I want an analyzer (a python script) that should run in such a fashion that when it is turned on, it continuously monitors the traffic of my Android device. I will have to make something similar to a proxy server but i am stucked how to do it.

Does your program run with the necessary rights at all? Under Linux and Windows a program needs extended rights to open raw sockets, which are necessary for sniffing. Under Windows there must be some group policy XY setting (I don't know Windows), under Linux the program needs root rights.
I don't know about such a policy too. But in the scenario displayed in the picture attached, there is no need for socket programming. I am also okay with passive sniffing.

i run Win 7
the hardware:
a. Joy-IT-Node MCU ESP8266
.. and besides that i also tried it with the following
b. ESP32-T Development Board CP2102 with Espressif ESP-WROOM-32 IoT WLAN & BLE Modul
yes: i have installed the > CP210x_Universal_Windows_Driver.zip
by the way: i could try to do all that on a linux machine. - on a MX-Linux-Sytem
any idea;
many thanks for any and all help in advance.
As of my opinion, You don't necessarily depend on the uPyCraft IDE. So there are several other ways to develop scripts and uploading them to Your board.
Some days ago I was facing problems with Python on the NodeMcu as well. Since I didn't like the tutorials around the web, I've set up one on GitHub, covering the end-to-end process (required software, drivers, firmware images, developing, flashing, uploading, etc.): python2nodemcu.
It depends on Mac and the NodeMcu board, but some of the topics may apply to other operating systems and boards as well.
And I think it covers the most relevant parts of the whole process, using the easiest tools around the web. Please have a look at it, but all in all it goes like this (short version of the linked documentation above):
Install Python 3
Verify with python --version
Or python3 --version
Install the correct SiLabs driver to enable serial USB-to-UART communication
See here
Find the device file (representing the interface to the physical device)
Try it using ls -la /dev/tty.*
Download the recent MicroPython firmware
You need the right one for Your board
Install the two Python-based libraries EspTool and PySerial
Try to erase the flash of Your device
Run python3 esptool.py --port /dev/tty.{device-file} erase_flash
Try to flash the original image or the MicroPython firmware to the board
Run python3 esptool.py --port /dev/tty.{device-file} write_flash 0x00000 {micropython-image-or-original-firmware}.bin
Try to connect to the board via the REPL prompt
Run screen /dev/tty.{device-file} 115200
You maybe need to try different baud rates (depending on Your driver, cable, etc.)
Connect to the board using Ampy
For example, try to list the files on Your device executing python3 ampy/cli.py --port /dev/tty.{device-file} --baud 115200 ls
Again, try other baud rates
Anyway, I've noticed that You do not necessarily need to push the physical flash button on the device.
I have been facing issue with automation execution of my script on one of the VM. I have automated the functionality of Saving a Document which is ideally a Windows Designed UI. I have tried using various technologies/tools like AutoIT, Python, Sikuli but the script halts if VM is minimized. It works perfectly fine is VM is open via RDP and I can see runtime execution. But If I minimize the RDP, the script halts at 'Save As' dialog box, none of the send keys (Cntrl+s) or (Enter) work via AutoIt script. Please help with some solution so as to have successfully execution of script even in minimized mode.
The reason why your script fails when it gets executed over a minimized RDP session is quite simple. GUI automation/testing tools need to have an unlocked, active desktop - otherwise the operation system thinks that it doesn't need to actually render GUI operations (which is time consuming) since there no user can that can see the rendered graphical user interface anyway. And programs don't communicate via GUIs normally ...
This is why QF-Test and other GUI automation/testing tools often have a note in their FAQs describing this kind of problem. For example FAQ 14 in the case of QF-Test, see https://www.qfs.de/qf-test-handbuch/lc/manual-en-faq.html
As described in the FAQ 14 on Windows 10 or Windows Server 2016 and in case of an RDP connection you need to modify the Registry. Go to
HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client
and add a new value
RemoteDesktop_SuppressWhenMinimized as DWORD having the value 2
After restarting you will then be able to minimize the RDP connections. However disconnecing or closing the RDP connection will probably still result in a failure.
You could try running tscon.exe RDP-Tcp#0 /dest:console as admin as mentioned here. This will disconnect your RDP connection but should leave all GUI programs running normally on the VM. I have personally used this with autoit on a VM and it worked OK. Of course you will not be able to monitor your script as it runs so this may or may not work for you.
I am writing a script in python, and part of it needs to connect to a remote computer using rdp. Is there a script or an api that I could use to create this function? Also, if there is not, is there a way to package a rdp application along side python and then use a python script to run it? Any help would be much appreciated. Thanks in advance, Nate
If you need an interactive window, use the subprocess module to start your rdesktop.exe (or whatever).
If you need to run some command automatically, you're probably better off forgetting about RDP and using ssh (with passwordless, passphraseless authentication via RSA or similar), psexec (note that some antivirus programs may dislike psexec, not because it's bad, but because it's infrequently been used by malware for bad purposes) or WinRM (this is what you use in PowerShell; it's like ssh or psexec, except it serializes objects on the sender, transmits, and deserializes back to an object on the recipient).
Given a choice among the 3, I'd choose ssh. Cygwin ssh works fine, but there are several other implementations available for Windows.

As per this GitHub comment, you can try to use libfreerdp via ctypes in Python.
See: FreeRDP library at GitHub which is a free remote desktop protocol library and clients.

I'm writing a Python script to access all computers on the network, log in to them and read some log files. I don't want to use something as low-level as socket, but I can if I must. I realize that my problem is similar to this question, but not the same.
Are there any modules for accessing external Windows machines?
Has anyone done anything like this before?
I'm specifically looking to log into Windows 7 machines, not unix.
Let's also assume that each computer I want to log into has Remote Desktop installed and enabled. I'm also not worried about network security or encryption because these files are not confidential. Windows machines don't have SSH installed on the by default do they?
There has to be something on the other side for you to talk to. This limits you to either setting up a "server" on each machine, installing a real server (i.e. sshd), building a "server" yourself and installing it, or using a built in and active feature of the OS.
Based upon this, what kind of system do you want to set up on these machines? What does it need to do? Just read the contents of a prespecified file list? Will that list change?
One solution is to turn on telnet, and use paramiko or twisted to
talk across it. This isn't very secure of course
Next up, set up a samba share, and access the folder remotely. This
is also insecure, though less so than telnet
You could find a ssh daemon port and run that, if you are so inclined
Psexec from sysinternals might work
Use twisted to build a server app with the features you need
Use ncat to listen on a port and spawn a cmd prompt
Be aware that most of the solutions for accessing windows remotely are... poor. The best solution is probably to roll your own, but that is hard work and you will probably make mistakes.
Also, Windows 7 is not exactly multi-user friendly. Individual processes can run as separate users, but the OS does not support having multiple users logged in at the same time. Someone is going to be the "user" and everyone else is just a process with a different credential set.
This is more an artificial limitation on M$'s part than anything technical. To see this in action, try to log in with RDP while a user is logged in locally. Fun times.
Per your edit, the easiest thing to do is just set up a samba share on the box.
After this share is set up:
with open(r'\\myCompNameOrIP\C\windows\logs\logfile.txt','rb') as logfile:
loglines = logfile.readlines()
Or you can use the gencat sample found here. Just give it r'\\myCompNameOrIP\C\windows\logs\*.txt' as the search path and watch the magic.
From Ubuntu I use samba:
In Bash:
gvfs-mount smb://them/folder
Here I give name, domain and password
Then in python:
folder = '/home/me/.gvfs/folder on them'
using the os module I read folders and files inside.
I am working in a small business environment.
Why not have each of the computers send the log file to the central computer?
