+# EXAMPLE.conf:
+#   An example configuration file for configuring the ucd-snmp snmpd agent.
+#
+###############################################################################
+#
+# This file is intended to only be an example.  If, however, you want
+# to use it, it should be placed in /etc/snmp/snmpd.conf.
+# When the snmpd agent starts up, this is where it will look for it.
+#
+# You might be interested in generating your own snmpd.conf file using
+# the "snmpconf" program (perl script) instead.  It's a nice menu
+# based interface to writing well commented configuration files.  Try it!
+#
+# Note: This file is automatically generated from EXAMPLE.conf.def.
+# Do NOT read the EXAMPLE.conf.def file! Instead, after you have run
+# configure & make, and then make sure you read the EXAMPLE.conf file
+# instead, as it will tailor itself to your configuration.
+
+# All lines beginning with a '#' are comments and are intended for you
+# to read.  All other lines are configuration commands for the agent.
+
+#
+# PLEASE: read the snmpd.conf(5) manual page as well!
+#
+
+
+###############################################################################
+# Access Control
+###############################################################################
+
+# YOU SHOULD CHANGE THE "COMMUNITY" TOKEN BELOW TO A NEW KEYWORD ONLY
+# KNOWN AT YOUR SITE.  YOU *MUST* CHANGE THE NETWORK TOKEN BELOW TO
+# SOMETHING REFLECTING YOUR LOCAL NETWORK ADDRESS SPACE.
+
+# By far, the most common question I get about the agent is "why won't
+# it work?", when really it should be "how do I configure the agent to
+# allow me to access it?"
+#
+# By default, the agent responds to the "public" community for read
+# only access, if run out of the box without any configuration file in 
+# place.  The following examples show you other ways of configuring
+# the agent so that you can change the community names, and give
+# yourself write access as well.
+#
+# The following lines change the access permissions of the agent so
+# that the COMMUNITY string provides read-only access to your entire
+# NETWORK (EG: 10.10.10.0/24), and read/write access to only the
+# localhost (127.0.0.1, not its real ipaddress).
+#
+# For more information, read the FAQ as well as the snmpd.conf(5)
+# manual page.
+
+####
+# First, map the community name (COMMUNITY) into a security name
+# (local and mynetwork, depending on where the request is coming
+# from):
+
+#       sec.name  source          community
+com2sec paranoid  default         public
+#com2sec readonly  default         public
+#com2sec readwrite default         private
+
+####
+# Second, map the security names into group names:
+
+#               sec.model  sec.name
+group MyROSystem v1        paranoid
+group MyROSystem v2c       paranoid
+group MyROSystem usm       paranoid
+group MyROGroup v1         readonly
+group MyROGroup v2c        readonly
+group MyROGroup usm        readonly
+group MyRWGroup v1         readwrite
+group MyRWGroup v2c        readwrite
+group MyRWGroup usm        readwrite
+
+####
+# Third, create a view for us to let the groups have rights to:
+
+#           incl/excl subtree                          mask
+view all    included  .1                               80
+view system included  .iso.org.dod.internet.mgmt.mib-2.system
+
+####
+# Finally, grant the 2 groups access to the 1 view with different
+# write permissions:
+
+#                context sec.model sec.level match  read   write  notif
+access MyROSystem ""     any       noauth    exact  system none   none
+access MyROGroup ""      any       noauth    exact  all    none   none
+access MyRWGroup ""      any       noauth    exact  all    all    none

+# System contact information
+#
+
+# It is also possible to set the sysContact and sysLocation system
+# variables through the snmpd.conf file.  **PLEASE NOTE** that setting
+# the value of these objects here makes these objects READ-ONLY
+# (regardless of any access control settings).  Any attempt to set the
+# value of an object whose value is given here will fail with an error
+# status of notWritable.

+# Process checks.
+#
+#  The following are examples of how to use the agent to check for
+#  processes running on the host.  The syntax looks something like:
+#
+#  proc NAME [MAX=0] [MIN=0]
+#
+#  NAME:  the name of the process to check for.  It must match
+#         exactly (ie, http will not find httpd processes).
+#  MAX:   the maximum number allowed to be running.  Defaults to 0.
+#  MIN:   the minimum number to be running.  Defaults to 0.
+
+#
+#  Examples:
+#
+
+#  Make sure mountd is running
+#proc mountd
+
+#  Make sure there are no more than 4 ntalkds running, but 0 is ok too.
+#proc ntalkd 4
+
+#  Make sure at least one sendmail, but less than or equal to 10 are running.
+#proc sendmail 10 1
+
+#  A snmpwalk of the prTable would look something like this:
+# 
+# % snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2021.2
+# enterprises.ucdavis.procTable.prEntry.prIndex.1 = 1
+# enterprises.ucdavis.procTable.prEntry.prIndex.2 = 2
+# enterprises.ucdavis.procTable.prEntry.prIndex.3 = 3
+# enterprises.ucdavis.procTable.prEntry.prNames.1 = "mountd"
+# enterprises.ucdavis.procTable.prEntry.prNames.2 = "ntalkd"
+# enterprises.ucdavis.procTable.prEntry.prNames.3 = "sendmail"
+# enterprises.ucdavis.procTable.prEntry.prMin.1 = 0
+# enterprises.ucdavis.procTable.prEntry.prMin.2 = 0
+# enterprises.ucdavis.procTable.prEntry.prMin.3 = 1
+# enterprises.ucdavis.procTable.prEntry.prMax.1 = 0
+# enterprises.ucdavis.procTable.prEntry.prMax.2 = 4
+# enterprises.ucdavis.procTable.prEntry.prMax.3 = 10
+# enterprises.ucdavis.procTable.prEntry.prCount.1 = 0
+# enterprises.ucdavis.procTable.prEntry.prCount.2 = 0
+# enterprises.ucdavis.procTable.prEntry.prCount.3 = 1
+# enterprises.ucdavis.procTable.prEntry.prErrorFlag.1 = 1
+# enterprises.ucdavis.procTable.prEntry.prErrorFlag.2 = 0
+# enterprises.ucdavis.procTable.prEntry.prErrorFlag.3 = 0
+# enterprises.ucdavis.procTable.prEntry.prErrMessage.1 = "No mountd process running."
+# enterprises.ucdavis.procTable.prEntry.prErrMessage.2 = ""
+# enterprises.ucdavis.procTable.prEntry.prErrMessage.3 = ""
+# enterprises.ucdavis.procTable.prEntry.prErrFix.1 = 0
+# enterprises.ucdavis.procTable.prEntry.prErrFix.2 = 0
+# enterprises.ucdavis.procTable.prEntry.prErrFix.3 = 0
+#
+#  Note that the errorFlag for mountd is set to 1 because one is not
+#  running (in this case an rpc.mountd is, but thats not good enough),
+#  and the ErrMessage tells you what's wrong.  The configuration
+#  imposed in the snmpd.conf file is also shown.  
+# 
+#  Special Case:  When the min and max numbers are both 0, it assumes
+#  you want a max of infinity and a min of 1.

++README.systemd
++--------------
++Net-SNMP provides two daemons, which support systemd system manager. 
++See http://www.freedesktop.org/wiki/Software/systemd to learn how
++systemd works. Both socket activation and notification is supported by these
++daemons.
++
++To enable systemd support, the sources must be compiled with
++--with-systemd configure option.
++
++snmpd - The SNMP agent
++----------------------
++Socket activation od snmpd daemon is implemented, but it's discouraged.
++The reason is simple - snmpd not only listens and processes SNMP requests
++from network, but also gathers system statistics counters, sends traps and
++communicates with subagents. It even opens few netlink sockets.
++
++In other words, snmpd should run from system start to properly work.
++This can be done in two ways:
++1) either as snmpd service unit with 'Type=notification' and without a socket
++   unit
++2) or as snmpd service unit with 'Type=simple', appropriate socket socket unit
++   and the snmpd service enabled. This way systemd creates the snmpd listening
++   socket early during boot and passes the sockets to snmpd slightly later
++   (but still during machine boot). This way systemd can paralelize start of
++   services, which depend on snmpd. Admins must adjust the socket file manually,
++   depending if the snmpd support AgentX, IPv6, SMUX etc.
++
++snmpd should be started with '-f' command line parameter to disable forking -
++systemd does that for us automatically.
++
++
++snmptrapd - The trap processing daemon
++--------------------------------------
++snmptrapd supports full socket activation and also notification (if needed).
++Both 'Type=simple' (with appropriate socket unit) and 'Type=notify' services
++will work. Again, '-f' parameter should be provided on snmptrapd command line.
++
++If integration with SNMP agent using AgentX protocol is enabled, snmptrapd should
++start during boot and not after first SNMP trap arrives. Same rules as for snmpd
++applies then.

++  Applications are welcome to reimplement the algorithms described

++
++  The following functionality is provided:
++
++  - Support for logging with log levels on stderr
++  - File descriptor passing for socket-based activation
++  - Daemon startup and status notification
++  - Detection of systemd boots
++
++  You may compile this with -DDISABLE_SYSTEMD to disable systemd

++  systemd (i.e. only sd_is_xxx() will stay useful).
++
++  Since this is drop-in code we don't want any of our symbols to be
++  exported in any case. Hence we declare hidden visibility for all of
++  them.

++  http://cgit.freedesktop.org/systemd/plain/src/sd-daemon.c

++  Informs systemd about changed daemon state. This takes a number of
++  newline separated environment-style variable assignments in a
++  string. The following variables are known:
++
++     READY=1      Tells systemd that daemon startup is finished (only
++                  relevant for services of Type=notify). The passed
++                  argument is a boolean "1" or "0". Since there is
++                  little value in signaling non-readiness the only
++                  value daemons should send is "READY=1".
++
++     STATUS=...   Passes a single-line status string back to systemd
++                  that describes the daemon state. This is free-from
++                  and can be used for various purposes: general state
++                  feedback, fsck-like programs could pass completion
++                  percentages and failing programs could pass a human
++                  readable error message. Example: "STATUS=Completed
++                  66% of file system check..."
++
++     ERRNO=...    If a daemon fails, the errno-style error code,
++                  formatted as string. Example: "ERRNO=2" for ENOENT.
++
++     BUSERROR=... If a daemon fails, the D-Bus error-style error
++                  code. Example: "BUSERROR=org.freedesktop.DBus.Error.TimedOut"
++
++     MAINPID=...  The main pid of a daemon, in case systemd did not
++                  fork off the process itself. Example: "MAINPID=4711"
++
++  Daemons can choose to send additional variables. However, it is
++  recommended to prefix variable names not listed above with X_.
++
++  Returns a negative errno-style error code on failure. Returns > 0
++  if systemd could be notified, 0 if it couldn't possibly because
++  systemd is not running.
++
++  Example: When a daemon finished starting up, it could issue this
++  call to notify systemd about it:
++
++     sd_notify(0, "READY=1");
++
++  See sd_notifyf() for more complete examples.
++
++  See sd_notify(3) for more information.

++  Similar to sd_notify() but takes a format string.
++

++                   "STATUS=Processing requests...\n"
++                   "MAINPID=%lu",
