I am trying to configure snmt and mgrt to watch traffic on my ppp0
interface.
But still no succes. I can talk to snmt using snmtwalk.
But whe I try to use mrtg I am getting error.
Also I donnot understand what is the port in the target directive
For example I use 2ublic@localhost
but I donot know what is that 2 doing.

I am sending all my log files so you can see what is going on.
Please help.

# 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 all included .1 80

## -or just the mib2 tree-

#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

# System contact information
#

# It is also possible to set the sysContact and sysLocation system
# variables through the snmpd.conf file:

syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root (configure /etc/snmp/snmp.local.conf)

# Example output of snmpwalk:
# % snmpwalk -v 1 localhost -c public system
# system.sysDescr.0 = "SunOS name sun4c"
# system.sysObjectID.0 = OID: enterprises.ucdavis.ucdSnmpAgent.sunos4
# system.sysUpTime.0 = Timeticks: (595637548) 68 days, 22:32:55
# system.sysContact.0 = "Me "

# 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

#proc httpd

# 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.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. 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.

# This alleviates the multiple line output problem found in the

# Run a shell script containing:
#
# #!/bin/sh
# echo hello world
# echo hi there
# exit 35
#
# Note: this has been specifically commented out to prevent
# accidental security holes due to someone else on your system writing
# a /tmp/shtest before you do. Uncomment to use it.
#
# exec .1.3.6.1.4.1.2021.50 shelltest /bin/sh /tmp/shtest

# enterprises.ucdavis.50.101.1 = "hello world."
# enterprises.ucdavis.50.101.2 = "hi there."
# enterprises.ucdavis.50.102.1 = 0

# Now the Output has grown to two lines, and we can see the 'hi
# there.' output as the second line from our shell script.
