unpack requires a buffer of 4 bytes

Hello, we would like to use the tool, unfortunately this error is always displayed. Can you help with that?

You've probably moved on by now, but this message is generated due to Python interrupting the \ as an escape character.

As per https://stackoverflow.com/questions/50504500/deprecationwarning-invalid-escape-sequence-what-to-use-instead-of-d I simply changed line 14 ...
from
banner = """
to
banner = r"""

This defines banner as a raw string rather than a unicode string. As a result I no longer get the warning message.

Side note: I use SSHScan on both Ubuntu and Debian machines. Only the Ubuntu machines generated this message. Likely related to the available version of python of the different distros.

Ubuntu
# python3 -V
Python 3.12.3

Debian
# python3 -V
Python 3.11.2
