# Perform some basic DNS, TCP, TLS, and ICMP testing targeting a remote endpoint or two,
# to spot transient issues you'd normally miss in 5-minute aggregate date
#
# DNS-TCP pings are emitted as a CSV to stdout, floodping is emitted to stderr

# Example of how to run it and capture both outputs.
#  NOTE: In the stderr redirect target shell, the stdout gets captured by the stdout subshell,
#        so we need to foce that to stderr.

HowTo Use

Windows

• Install gnupg for Windows from gnupg.org (NOT GP4Win, the regular one).
• Plug in your Yubikey, and run gpg --card-status, and make sure it emits some useful output about the card.

WSL1

We need WSL1 to act as the network proxy between the Windows TCP litening assuan socket, which is only on localhost, and a tcp socket listening on a host port that we can access from WSL2.
