Exscript TimeoutException - python

So I finally got exscript working properly (I think). I wanted to test it, so I setup a simple python script I believe should work:
from Exscript.util.interact import read_login
from Exscript.protocols import SSH2
account = read_login()
conn = SSH2()
conn.connect('router.domain.com')
conn.login(account)
conn.execute('terminal length 0')
conn.execute('show version')
print conn.response
conn.send('exit\r')
conn.close()
I run the script and I'm presented with the following:
kidd#server scripts$ python test1.py
Please enter your user name [kidd]:
Please enter your password:
It sits there for about 20 seconds, then I get this:
Traceback (most recent call last):
File "test1.py", line 7, in <module>
conn.login(account)
File "/usr/lib/python2.7/site-packages/Exscript/protocols/Protocol.py", line 597, in login

File "/usr/lib/python2.7/site-packages/Exscript/protocols/Protocol.py", line 846, in auto_app_authorize

raise TimeoutException(msg)
Exscript.protocols.Exception.TimeoutException: Buffer: '\rThis is a private system \r\n \r\nrouter>'
Am I missing something simple? Just trying to login to a router (as a normal user, non-privilege mode), run a show version, then log out. Any help would be appreciated. Thanks.

It looks like the banner you have configured is messing with the prompt that Exscript is expecting back from the device. I'd suggest either tweaking the protocol driver within Exscript to handle the prompt better, or making sure your banner is set up properly (or removing it all together)

VI_ERROR_TMO (-1073807339) on Anritsu OSA

I'm working on interfacing an old Optical Spectrum Analyzer Anritsu MS9710B with a RS232 connection. A year ago, I managed to comunicate with him, send SCPI command using pyvisa and receive data. Today, I execute the exact same code with libraries up to date and I get an error Timeout when I query IDN or anything. The RS232-USB drivers are ok, I manage to open a communication but a query or read fail.
I changed the parameter to "RS232C" on the OSA parameters and my communication parameters are the same between OSA and program. Following advices from the forum, I tried the connection with NI-VISA where I get the same error. I tried to change timeout parameter, write_termination and read_termination but there isn't any change. The manual is very hard to understand termination value, but when it worked I didn't add anything.
I don't know anymore what to do.
Any advices and help would be warmly welcome to fix my problem !

ciscoaxl api python errors

I am starting out working on looking into using Python for some Cisco CUCM automation. I found the plugin ciscoaxl here, I installed it and programed the following script:
from ciscoaxl import axl
cucm = "10.10.20.1"
username = "axlusr"
password = "password1"
version = "12.5"
ucm = axl(username, password, cucm, version)
for phone in ucm.get_phones():
print(phone.name)
I am connected to Cisco's DevNET Sandbox and all the login and configuration for the AXL user appear to be correct, however I get the following output when I attempt to run the script:
Traceback (most recent call last):
File "%home%\AppData\Local\Programs\Python\Python39\axl-test.py", line 7, in <module>

raise Fault(
zeep.exceptions.Fault: Unknown fault occured
I have run it on Windows10 in an IDLE enviornment, from the Linux-Subsystem (Ubuntu 20.04) via python and ipython3.
After some additional research this is a know issue with CUCM 12.5. It should be fixed in CU1 see here: https://github.com/mvantellingen/python-zeep/issues/989
I still receive this error on 12.5.1.12900-115, but I receive it when I don't have the appropriate permissions. Fixing user permissions for AXL access resolves it.

pygatt NotificationTimeout: None

I try to read characteristic data out of an BLE based Sensor. Therefore i use the pygatt module
import pygatt
adapter = pygatt.GATTToolBackend()
try:
adapter.start()
device = adapter.connect("2B:01:56:6C:F4:E6")
value= device.char_read("00007502-0000-1000-8000-00805f9b34fb")
finally:
adapter.stop()
Everytime i try to run this in my Linux console (with Python 2.7.16) i get an error :
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

raise NotificationTimeout()
pygatt.exceptions.NotificationTimeout: None
I am completely lost on this error. Do you know how to fix this ?
Any help on this much appreciated. Thanks in advance...
Since I was facing the same problem and nobody out there seemed to have this problem...
Well, the problem was that the requested UUID characteristic didn't exist/was invalid. Make sure that you've typed it right or that you haven't clipped some part off when copying from putty or similar (Totally not speaking from experience! Of course!)
If you are pasting a characteristic UUID from the internet or a similar device, maybe your device don't have this UUID.
OR
This could (not tested, but should make sense) also happen if you write to an UUID which is non-writeable (read-only/subscribe-only).
If you're sure that everything is right and that you have triple-checked the UUID with a dedicated sniffer or simply a BLE Scanner on your Phone, then the device is probably closing the connection too fast.
TROUBLESHOOTING:
You can manually connect with the device and issue commands using:
gatttool -I
When you are inside the program, type:
connect aa:bb:cc:dd:ee:ff
And then, before the connection closes:
char-read-uuid xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
and analyse what happens. If it works there, it should also work in python.

EFOError when trying to connect Pyftpsync to remote server on port 22

I am trying to sync two folders via FTP, yes I know there are better or different ways but for now I need to implement it this way, I was trying the example code from pyftpsync since well, a sample code should work easily right? I am just trying to connect between some test folders I made, one is empty(local) and the remote has a single text file that I want to fetch. It tries to connect but after about 2 minutes I get this error.
Well, my FTP does work outside of python. I can connect over WinSCP just fine.
Some places mentioned that a proxy could possibly cause this, but it seems I am not behind a proxy currently, but maybe I did not set that properly and it believes there should be a proxy somehow?
Here is my code, just using commands on the prompt for pyftpsync produces the same errors for me. So it is possible some input parameter is off causing all of this.
import time
import os
import re
import shutil
import string
import sys
from ftpsync.targets import FsTarget
from ftpsync.ftp_target import FtpTarget
from ftpsync.synchronizers import DownloadSynchronizer
#synchronize a local folder with ftp
local = FsTarget( "C:\\testfolder\\" )
user = "login"
passwd = "password"
remote = FtpTarget("/my/folder/location/testfold/", "126.0.0.1",port=22, username=user,password=passwd,tls=False,timeout=None,extra_opts=None)
opts = {}
s=DownloadSynchronizer(local, remote, opts)
s.run()
This is the output I am getting, I have edited out the folder names and IP addresses.

Anyways any possible troubleshooting ideas would help. Thank you.
Pyftpsync uses FTP protocol.
You are connecting to port 22, which is used for SSH/SFTP.
So if your server is actually SFTP server, not FTP server, you cannot use Pyftpsync with it.

Python imaplib: Cannot logout from imap

I wrote a python script to automate some tasks on my mail account. So, I can login to my yahoo mail account, read, delete (via imap) and send emails (via smtp). After that I want to logout. However, I am getting this error, which I do not know how to repair:
This is what happens:
Exception in close_imap
Traceback (most recent call last):
File "/Users/Tom/MeineDaten/Programmieren/Sportwetten/Tipico/Report-Gambling-Apps/emailing/Mailer.py", line 55, in close_imap

', '.join(Commands[name])))
imaplib.IMAP4.error: command CLOSE illegal in state LOGOUT, only allowed in states SELECTED
And this is the corresponding code:
import imaplib
...other code here...
def close_imap(self):
if self.imap is None:
print("close_imap: self.imap is None. No further action taken. Returning.")
return
try:
self.imap.close()
self.imap.logout()
except Exception:
print("Exception in close_imap")
print(str(traceback.format_exc()))
pass
What am I doing wrong here?
You are trying to close a folder but you have not selected any.
This may be due to two thinks:
You never selected a folder in this session
You already closed the folder but you are trying to close it a second time.
You should only close a folder one time.
Note: This is not necessary in the IMAP protocol to close a folder before logging out.
