Subject: [PATCH] configure: Report supported authentication and encryption
modes correctly
Commit 9e49de2e03b1 ("NEWS: snmplib: AES-192/AES-256 compatibility with SNMP
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] Add support for digests detected from ECC certificates
Previously, the digest could be detected on RSA certificates only. This
patch adds detection for ECC certificates.

This fixes issue, that is caused by parsing IP address twice.
First as IPv4 and as IPv6 at second, even thow the address was
properly parsed as a valid IPv4 address.

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.

###############################################################################
#
# 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

# 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"
# 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:
# Open up the whole tree for ro, make the RFC 1213 required ones rw.

# 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.prIndex.3 = 3
# 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.prErrorFlag.3 = 0

# 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.
