  19 # ipsec         init.d script for starting and stopping
  20 #               the IPsec security subsystem (KLIPS and Pluto).
  21 #
  22 # This script becomes /etc/rc.d/init.d/ipsec (or possibly /etc/init.d/ipsec)
  23 # and is also accessible as "ipsec setup" (the preferred route for human
  24 # invocation).
  25 #
  26 # The startup and shutdown times are a difficult compromise (in particular,
  27 # it is almost impossible to reconcile them with the insanely early/late
  28 # times of NFS filesystem startup/shutdown).  Startup is after startup of
  29 # syslog and pcmcia support; shutdown is just before shutdown of syslog.
  30 #

  32 # description: IPsec provides encrypted and authenticated communications; \
  33 # KLIPS is the kernel half of it, Pluto is the user-level management daemon.
