Research / CISCO") removed SHA-128 and SHA-192 support and added support for
SHA-224, SHA-256, SHA-384 and SHA-512. Commit 329a9d3c9d63 ("revamp auth/priv
protocol constants handling") added support for several AES encryption modes.
Make the configure script report which modes are supported.

Subject: [PATCH] Linux: IF-MIB: Fix a memory leak
The Linux kernel regenerates proc files in their entirety every time a 4 KiB
boundary is crossed. This can result in reading the same network interface
twice if network information changes while it is being read. Fix a memory
leak that can be triggered if /proc/net/dev changes while being read.

Subject: [PATCH] MIB-II: Only log once that opening /proc/net/if_inet6 failed
If IPv6 has been disabled (ipv6.disable=1) then opening /proc/net/if_inet6
fails. Only log this once instead of thousand of times a day.

Subject: [PATCH] snmplib: Fix a memory leak in scapi.c
This patch avoids that Valgrind reports the following leak:
==1069== 3,456 bytes in 72 blocks are definitely lost in loss record 1,568 of 1,616
==1069== at 0x4C29BE3: malloc (vg_replace_malloc.c:299)
==1069== by 0x70A63B7: CRYPTO_malloc (in /usr/lib64/libcrypto.so.1.0.2k)
==1069== by 0x7161B06: EVP_MD_CTX_create (in /usr/lib64/libcrypto.so.1.0.2k)
==1069== by 0x4EA3017: sc_hash (in /usr/lib64/libnetsnmp.so.31.0.2)
==1069== by 0x4EA1CD8: hash_engineID (in /usr/lib64/libnetsnmp.so.31.0.2)

#
# snmpd.conf:
# An example configuration file for configuring the ucd-snmp snmpd agent.
#
###############################################################################
#
# This file is intended to only be as a starting point. Many more
# configuration directives exist than are mentioned in this file. For
# full details, see the snmpd.conf(5) manual page.
#
# All lines beginning with a '#' are comments and are intended for you
# to read. All other lines are configuration commands for the agent.
###############################################################################
# Access Control
###############################################################################
# As shipped, the snmpd demon will only respond to queries on the
# system mib group until this file is replaced or modified for
# security purposes. Examples are shown below about how to increase the
# level of access.
# 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 to the mib tree as well.
#
# For more information, read the FAQ as well as the snmpd.conf(5)
# manual page.
####
# First, map the community name "public" into a "security name"
# sec.name source community
com2sec notConfigUser default public
####
# Second, map the security name into a group name:
# groupName securityModel securityName
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
####
# Third, create a view for us to let the group have rights to:
# Make at least snmpwalk -v 1 localhost -c public system fast again.
# name incl/excl subtree mask(optional)
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
####
# Finally, grant the group read-only access to the systemview view.
# group context sec.model sec.level prefix read write notif
access notConfigGroup "" any noauth exact systemview none none
# -----------------------------------------------------------------------------
# Here is a commented out example configuration that allows less
# restrictive access.
# 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.
## sec.name source community
#com2sec local localhost COMMUNITY
#com2sec mynetwork NETWORK/24 COMMUNITY
## group.name sec.model sec.name
#group MyRWGroup any local
#group MyROGroup any mynetwork
#
#group MyRWGroup any otherv3user
#...
## incl/excl subtree mask

#view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc
## context sec.model sec.level prefix read write notif
#access MyROGroup "" any noauth 0 all none none
#access MyRWGroup "" any noauth 0 all all all
###############################################################################
# Sample configuration to make net-snmpd RFC 1213.
# Unfortunately v1 and v2c don't allow any user based authentification, so
# opening up the default config is not an option from a security point.
#
# WARNING: If you uncomment the following lines you allow write access to your
# snmpd daemon from any source! To avoid this use different names for your
# community or split out the write access to a different community and
# restrict it to your local network.
# Also remember to comment the syslocation and syscontact parameters later as
# otherwise they are still read only (see FAQ for net-snmp).
#
# First, map the community name "public" into a "security name"

# system.sysObjectID.0 = OID: enterprises.ucdavis.ucdSnmpAgent.sunos4

# We do not want annoying "Connection from UDP: " messages in syslog.
# If the following option is commented out, snmpd will print each incoming
# connection, which can be useful for debugging.

# -----------------------------------------------------------------------------
###############################################################################
# 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 (commented out by default):
#
# 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 process mib tree would look something like this:
#
# % snmpwalk -v 1 localhost -c public .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.prNames.1 = "mountd"

# enterprises.ucdavis.procTable.prEntry.prMin.1 = 0

# 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.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.
#

###############################################################################
# Executables/scripts
#
