ESPFinder

[enesbcs]

ESP Easy Netscan is a very nice and handy application, thanks to grovkillen..
It's too bad, is just for Windows, so i stealed the idea, and made a simpler looking version in Python3 to Linux fans, like me.

ESPFinder first beta:

Happy to have inspired

Thanks enesbecs and grovkillen,
I'm also a Linux user, I will give it a try!
Thanks for sharing.

I tried installing espfinder, but I'm getting errors when executing "sudo pip3 install multiprocessing ctypes itertools contextlib". The error is:
Command "python setup.py egg_info" failed with error code 1

Do you know what am I missing?
Thanks

I am using Ubuntu Linux 16.04 with latest stable Python 3.5.2 from ubuntu repositories with pip 8.1.1.
Maybe you can try to upgrade pip:

Code: Select all

sudo python -m pip install --upgrade pip
sudo pip3 install --upgrade setuptools

Thanks for your reply. I tried what you proposed - I have the latest versions (the message I get is "Requirement already up-to-date"). I have python 3.5.2 and pip 10.0.1.
The installation of "multiprocessing" fails.
There is something in my installation which is outdated or missing.

Maybe multiprocessiong is already installed in a non-pip way which can not be overwritten by pip.
Try to reinstall stdlib:
sudo apt-get install --reinstall libpython3.5-stdlib

Hi,
I downloaded multiprocessing-2.6.2.1.tar.gz and the INSTALL.txt says: "Python 2.6 and newer versions already come with multiprocessing."
When trying to install it (using sudo pip3 install multiprocessing) the error I get is:

Code: Select all

Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-install-vw9qsdn_/multiprocessing/setup.py", line 94
        print 'Macros:'
                      ^
    SyntaxError: Missing parentheses in call to 'print'
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-vw9qsdn_/multiprocessing/

It seems like the error is that print cannot be followed by ' (single quote) in python3. It has to be "

I also checked in /usr/lib/python3.5 and I have: ctypes, multiprocessing. When I try to execute:
sudo pip3 install itertools
I get the message:
Collecting itertools
Could not find a version that satisfies the requirement itertools (from versions: )
No matching distribution found for itertools

I get a similar message with sudo pip3 install contextlib

Can we somehow compare our installations?

Can you try to run espfinder.py? I think all prerequisites already satisfied, and nothing left to install.

Thanks again for your reply. I'm afraid it doesn't work
The GUI starts but nothing is displayed. And when I click on "Refresh", I get a lot of errors:

Code: Select all

Process Process-1:

Similarly with the console version

This means, that the python program are unable to determine your machine local address from the "ifconfig" command output. Can you share the output of ifconfig?
I will have to implement some basic error messages...

yes, here it is:

I think i get it, i expected eth0-9 and wlan0-9. Fixed, and uploaded to github.

Thanks! It works
Can I ask something:
when I start the gui, it shows nothing. After I click on Refresh, I get the list of devices. Is this normal?

Thanks again for the implementation and your support!

You are welcome. Yes the need to click on Refresh is by design, but in the future it can be change.. but first i have to implement some sort of progress feedback. Since i using multiprocessing for fast pinging it is hard to sync a global variable in the main app.
Also developed some sort of Windows compatibility, just for fun, but it is slow as hell.
