WireGuard over TCP with udptunnel

WireGuard over TCP with udptunnel

udptunnel is a small program which can tunnel UDP packets bi-directionally over a TCP connection. Its primary purpose (and original motivation) is to allow multi-media conferences to traverse a firewall which allows only outgoing TCP connections.

Server

# udptunnel -s 443 127.0.0.1/51820

Created February 16, 2021 20:29 — forked from rvaidya/database_to_parquet.py
Dump database table to parquet file using sqlalchemy and fastparquet. Useful for loading large tables into pandas / Dask, since read_sql_table will hammer the server with queries if the # of partitions/chunks is high. Using this you write a temp parquet file, then use read_parquet to get the data into a DataFrame
import pandas as pd
import numpy as np
import fastparquet
from sqlalchemy import create_engine, schema, Table
# Copied from pandas with modifications
def __get_dtype(column, sqltype):
