Can't ping localhost with python [duplicate]

This question already has an answer here:
ICMP pinger application in Python - error: operation not permitted?
(1 answer)
Closed 2 months ago.
By running this simple code in Python
>>> from pythonping import ping
>>> ping('127.0.0.1', verbose=True)
I get this error
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

PermissionError: [Errno 1] Operation not permitted
I tried running it as sudo but to no avail.
I don't know what the cause of the error is, so I'm hoping for intelligent answers from knowledgeable people.
Pythonping is a public repository I found on PyPI.
In the code I try to simply ping Localhost, returning the results on the screen when I set the "verbose" parameter to True.

you need root user permission to use it
run python3 such as root user then everything will be OK. and if you use it on a file run it with the root user.

Scope Tektronix TDS 1012 gives an error with pyvisa

I'm trying to connect a Tektronix TDS 1012B oscilloscope to my PC using Pyvisa.
I'm using Kubuntu 20.04, Python version 3.9.7 and Pyvisa version 1.11.3.
I do the following :
>>> import pyvisa
>>> rm = pyvisa.ResourceManager()
>>> rm.list_resources()
('USB0::1689::870::C021027::0::INSTR')
>>> scope = rm.open_resource('USB0::1689::870::C021027::0::INSTR')
>>> scope.query("*IDN?")
But I get this error message:

When I use another type of oscilloscope this very simple code works fine. And when I use Pyvisa under Windows instead of Kubuntu, it also works.
Can someone help me fix this annoying issue?

Check out this link to a post from Tek in Tek's forums. They suggest using the pyvisa-py native Python VISA backend. This command instructs to use the pyvisa-py backend
rm = visa.ResourceManager('#py')
and you install by
pip install pyvisa-py
I don't have an Ubuntu machine at my fingertips so I don't know if there are packages available for installing from apt.

Connecting my TBS 1064 in SUSE has problems due to write permissions. This results in an time-out on requests like ask(). It is likely due to udev/rules, although I did not figure out what to put exactly to make it always work. For now one has to put the write permission (admin) for every USB reconnect, but then it is working.
Other devices do not have this problem and it is only a linux issue.

python 2.7.6 to 2.7.12 broke my script

I'm working on a simple script to send data to an elasticsearch node, but after changing my python version the script no longer runs. It says the error is on line 6, but I have no idea why. I've tried adding a comma after the 'yes', but it had no effect. I've tried moving my braces and parenthesis down and it had to effect. (I'm leaving out the import and other defined variables for brevity)
if "Temporary failure in name resolution" or "Timeout" in output:
es.index(index='data', doc_type='data', body={
'macs' : '',
'data' : line,
'date' : datetime.now(),
'down' : 'yes' })
Here are the errors:
snmpwalk: Timeout
Traceback (most recent call last):
File "script.py", line 6, in <module>
'down' : 'yes' })

Thanks

This could either be a network issue or mmapfs directory for elastic search has maxed out.
Try running the following to restart your network server
sudo service network-manager restart
If it does not work, then change your mmap count by running this command
sudo sysctl -w vm.max_map_count=262144

Python code error message that I don't understand

I am having problems decoding this error message for the python on my Raspberry Pi. Please don't tell me to head to that SE, they sent me here as no one really knew what it means. It is from [GitHub][1]
Here is the error output:
Traceback (most recent call last):
File "/home/pi/piarduino/MissionControl-master/mcDesk.py", line 8, in <module> serialFromArduino = serial.Serial("/dev/serial/by-id/usb-FTDI_FTDI_FT232R_USB_UART_A900aepy-if800-port0", 115200)
File "/usr/lib/python2.7/dist-packages/serial/serialutil.py", line 260, in __init__
self.open()
File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 276, in open
raise SerialException("could not open por %s: %s" % (self._port, msg))
SerialException: could not open port /dev/serial/by-id/usb-FTDI_FTDI_FT232R_USB_UART_A900aepy-if800-port0: [Errno 2] No such file or directory: '/dev/serial/by-id/usb-FTDI_FTDI_FT232R_USB_UART_A900aepy-if800-port0'

Basic troubleshooting:
Try running your script as root using sudo. It's possible you're being denied access to the serial port.
Run ls /dev/serial/by-id in a shell. Make sure the serial port you are trying to open exists and matches exactly with the port you're trying to open in your program.
If neither of those options work, try these steps.

ftplib error while execution

While accessing the remote server through FTP I am getting following error. Not sure whats the problem of it so I can solve. Any lead will be helpful.
Code:
import ftplib
from ftplib import FTP
ftp = ftplib.FTP("server_name")
Error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python2.6/ftplib.py", line 116, in __init__
self.connect(host)
File "/usr/lib64/python2.6/ftplib.py", line 131, in connect
self.sock = socket.create_connection((self.host, self.port), self.timeout)
File "/usr/lib64/python2.6/socket.py", line 553, in create_connection
for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno -2] Name or service not known

(I don't have enough reputation to just leave a comment for #LonelySoul, and anyone else.)
You'll encounter the Name or service not known exception if "server_name" includes the protocol. Simply removing ftp:// resolved the issue for me.

The error is telling you that it can't find the host named server_name. So, that's what you need to debug.
If you ping server_name in your terminal/DOS prompt, does it work, or give you an error like cannot resolve server_name? What if you ftp server_name in the terminal?
If everything works in the terminal, and you don't have a silly typo in your code, your next step is to debug why Python is getting it wrong. Write some code that tries to call getaddrinfo explicitly and see what happens. Try socket.connect on a normal IPv4 socket to see if it works. (If so, the problem is probably something to do with IPv6.) And so on.
More likely, it will fail in the terminal as well. In that case, either you've got the wrong name for the server, or you've got something wrong with your network or system setup; either way, it's not a programming problem, and StackOverflow won't be able to help you further.
