#!/bin/sh -e
# This script forces an application to use the i2p SOCKS proxy at port
# 4447, and optionally allows the HTTP proxy at port 4444 to be used
# instead. This is because the alternatives have drawbacks:
#
# Only using the HTTP proxy means you can't access non-HTTP resources,
# e.g., gopher.
#
# Only using the SOCKS proxy means your browser will use the default
# user agent, which is not great for anonymity and some eepsites (e.g.,
# zzz.i2p and stats.i2p) will detect you as an inproxy and block you.
#
# This script should give you the best of both worlds, HTTP proxy for
# HTTP, SOCKS for everything else. This is assuming your application
# respects the http_proxy environment variable (most browsers do).

export http_proxy='http://127.0.0.1:4444'

# gotta use a tempfile since proxychains may read the file multiple
# times, so a fd would cause errors
