# specifies refusal of link-layer compression defaults

down-pre
# runs client-side "down" script prior to shutdown, to help minimise risk...
# of session termination packet leakage

allow-pull-fqdn
# allows client to pull DNS names from server
# we don't use but may in future leakblock integration

explicit-exit-notify 3
# attempts to notify exit node when client session is terminated
# strengthens MiTM protections for orphan sessions

hand-window 37
# specified duration (in seconds) to wait for the session handshake to complete
# a renegotiation taking longer than this has a problem, & should be aborted

mssfix 1400
# congruent with server-side --fragment directive

# don’t forget to create /etc/openvpn/password.txt with the word ‘nope’ on 1st & 2nd line
auth-user-pass password.txt
# passes up, via bootstrapped TLS, SHA512 hashed token value to authenticate to darknet

# auth-retry interact
# 'interact' is an experimental parameter not yet in our production build.
