# Note on debugging flags:
# -DDEBUG_ZLB shows all ZLB exchange traffic
# -DDEBUG_HELLO debugs when hello messages are sent
# -DDEBUG_CLOSE debugs call and tunnel closing
# -DDEBUG_FLOW debugs flow control system
# -DDEBUG_FILE debugs file format
# -DDEBUG_AAA debugs authentication, accounting, and access control
# -DDEBUG_PAYLOAD shows info on every payload packet
# -DDEBUG_CONTROL shows info on every control packet and the l2tp-control pipe
# -DDEBUG_PPPD shows the command line of pppd and how we signal pppd (see below)
# -DDEBUG_HIDDEN debugs hidden AVP's
# -DDEBUG_ENTROPY debug entropy generation
# -DDEBUG_CONTROL_XMIT
# -DDEBUG_MAGIC
# -DDEBUG_FLOW_MORE
# -DDEBUG_AUTH
#
# -DTEST_HIDDEN makes Assigned Call ID sent as a hidden AVP
#
# -DTRUST_PPPD_TO_DIE 
#
# Defining TRUST_PPPD_TO_DIE disables a workaround for broken pppds. Do NOT
# define this unless you fully trust your version of pppd to honour SIGTERM. 
# However, if you experience hanging pppd's, which cause xl2tpd to also hang,
# enable this. 
# The cost of not trusting pppd to die (and shoot it down hard), is that your
# pppd's ip-down scripts will not have a chance to run.
#
# For more details see: http://bugs.xelerance.com/view.php?id=739
#
# Confirmed bad versions of pppd:
# - ppp-2.4.2-6.4.RHEL4
# Confirmed good version of pppd:
# - recent Ubuntu/Debian pppd's
#
# ppp 2.4.3 sends a SIGTERM after 5 seconds, so it should be safe to
# trust pppd. This work around will be removed in the near future.
