stuck in process sock.connect(sa) or making connections

Question

I just set up Kali with GNOME3.38 desktop, and also have set up the python development tools I usually use. But when I start to use imapclient in the interactive python shell and do: conn = IMAPClient('imap.gmail.com', ssl=True) or:

with requests.get('https://chromedriver.storage.googleapis.com/LATEST_RELEASE') as response:
       print(response)

nothing really happens rather than just be stuck. I hit Ctrl + C to stop the process and I see the same tracebacks.

>>> import requests
>>> with requests.get('https://chromedriver.storage.googleapis.com/LATEST_RELEASE') as response:
...     response.raise_for_status()
...

and for the imapclient:

>>> conn = IMAPClient('imap.gmail.com', ssl=True)

    sock = socket.create_connection(
  File "/usr/lib/python3.9/socket.py", line 831, in create_connection
    sock.connect(sa)

Now, I didn't really mess with anything else in my kali machine.. But is it GNOME that's causing this, or is there something wrong with the files in kali?

Another problem is that pip install [library_name] takes too long to process. My internet speed is okay for the speed, btw.

Answer 1

I had that problem too where even a simple pip list took ages and were stuck the following error.

This can basically happen if your host has IPv6 support but your network doesn't. You can quickly check so by disabling IPv6 support on the fly with:

sysctl net.ipv6.conf.all.disable_ipv6=1

Once you disabled IPv6, try pip again. You might also check if a simple ping resolves to an IPv4 or IPv6.

Also, in my case, noticed that my OPNsense firewall did block a lot of stuff with suricata. Some rule tweaking later I got stuff to work.

Hope this helps ;)
