[Question][Hw1] Workaround for socket.gaierror

[gunsodo]

This might not be an exact question but I want to note down something which might be useful for others as I prefer to work on my machine due to convenience. If this is a proper workaround, I will close this issue within 48 hours.

Environment:

• OS: macOS Big Sur 11.1
• Machine: MacBook Pro M1 (using Rosetta)
• Python version: 3.6.8

The first time I try to test the interface using,

from oracle_python_v1_2 import pad_oracle
ret_pad = pad_oracle(’0x1234567890abcdef’, ’0x1234567890abcdef’)

it produces this error

>>> ret_pad = pad_oracle('0x1234567890abcdef', '0x1234567890abcdef')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "***/oracle_python_v1_2.py", line 14, in pad_oracle
    sock.connect((HOST, PORT))
socket.gaierror: [Errno 8] nodename nor servname provided, or not known

To fix the issue, I followed this answer from stackoverflow. And to do this (editing /etc/hosts), you might need the administrator's privilege.

Closing this since more than 48 hours have passed without any issues.
