SNMP::NPAdmin is a high-level API to query printers via SNMP.

SYNOPSIS

# object-oriented
$p= SNMP::NPAdmin->new(
printer => porky,
community => corpslp
);
printf "Your printer, %s, does%s support PCL.n",
$printer, ( $p->pcl() ? "" : " not");

# procedural
$p= npa_connect(
printer => porky,
community => corpslp
);
printf "Your printer, %s, does%s support PCL.n",
$printer, ( npa_pcl( $p) ? "" : " not");

The SNMP::NPAdmin package is a complete port of a SNMP/printer utility called npadmin that provides a high-level interface to query printers via SNMP without specific knowledge of SNMP MIBs or the printers vendor-specific configuration.

The original npadmin was written in C++ by Ben Woodard who continues to maintain it on SourceForge.

The primary objective in this port is to have a maintainable and extensible version of the same functionality that the original npadmin provides.
It is not optimized for performance at all; it is optimized for extensibility and maintainability. The original npadmin is very much extremely performance, the idea being to query many printers very quickly, especially since SNMP can be quite slow.

To be fair, SNMP::NPAdmin might even be slow by Perl standards due to the extensive use of run-time compilation through the AUTOLOAD subroutine. I dont necessarily believe this since a programmer/sys-admin frequently will not use all of the available methods/subroutines which would typically be compiled during startup; given that only a few methods/subroutines will be called, then only a few will be compiled during the processs lifetime. Probably the difference in speed due to this will be insignificant either way.

The design was chosen in order to get as much information into a maintainable table format and make the logic as generic as possible; not for speed.

So this is your choice. If you have some unsupported printers and you want to be able to modify the code to support them then use SNMP::NPAdmin. If you need to support a lot of printers continuously with this kind of utility then you should use Ben Woodards npadmin.

BridgeQuery is a Perl extension for retrieving bridge tables.

SYNOPSIS

use SNMP::BridgeQuery;
use SNMP::BridgeQuery qw(querymacs queryports queryat);

$fdb = queryfdb(host => $address,
comm => $community);
unless (exists $fdb->{error}) {
($fdb->{$mac} = "n/a") unless (exists $fdb->{$mac});
print "This MAC address was found on port: ".$fdb->{$mac}."n";
}

BridgeQuery polls a device which responds to SNMP Bridge Table queries and generates a hash reference with each polled MAC address as the key and the associated port as the value. The specific MIBs that are polled are described in RFC1493.

SNMP::BridgeQuery requires Net::SNMP in order to function. (Checked for during perl Makefile.PL)

Devices can be switches, bridges, or most anything that responds as a OSI Layer 2 component. Layer 3 devices do not generally respond and will cause an error. If an error is generated, it will return a hash reference with a single element (error) which can be tested for.

Two other functions (querymacs & queryports) can be explicitly exported. They work the same way as queryfdb, but they return MAC addresses or ports (respectively) with the SNMP MIB as the hash key.

A newly added function (queryat) can be used on layer 3 switches to poll the Address Translation Tables. This is similar to the data returned by the queryfdb function, but it returns the IP address of the device and the associated interface (separated by a pipe |) with the MAC address as the key. On a layer 3 switch, this interface probably does not correspond to a physical port, but more likely refers to a vlan ID. Using this function on a layer 2 device will generate a trapped error.

Mon::SNMP is a Perl module created to decode SNMP trap.

SYNOPSIS

use Mon::SNMP;

$trap = new Mon::SNMP;

$trap->buffer($snmptrap);

%traphash = $trap->decode;

$error = $trap->error;

Mon::SNMP provides methods to decode SNMP trap PDUs. It is based on Graham Barrs Convert::BER module, and its purpose is to provide SNMP trap handling to "mon".

METHODS

new

creates a new Mon::SNMP object.

buffer ( buffer )

Assigns a raw SNMP trap message to the object.

decode

Decodes a SNMP trap message, and returns a hash of the variable assignments for the SNMP header and trap protocol data unit of the associated message. The hash consists of the following members:

version => SNMP version (1)
community => community string
ent_OID => enterprise OID of originating agent
agentaddr => IP address of originating agent
generic_trap => /COLDSTART|WARMSTART|LINKDOWN|LINKUP|AUTHFAIL|EGPNEIGHBORLOSS|ENTERPRISESPECIFIC/
specific_trap => specific trap type (integer)
timeticks => timeticks (integer)
varbindlist => { oid1 => value, oid2 => value, ... }

SNMP Watcher is a tool for retrievinginformation using the Simple NetworkManagement Protocol (SNMP). SNMP is astandard protocol for monitoring andcontrolling network components.

It can be usedto query network components for informationabout their configuration, activity, and errors. This program queries SNMP agents over TCP/IP and AppleTalk.

SNMP::Monitor is a Perl package for monitoring remote hosts via SNMP.

SYNOPSIS

require SNMP::Monitor;

# Read a configuration file
my $config = SNMP::Monitor->Configuration("/etc/snmpmon/config");

# Create a new monitor
my $monitor = SNMP::Monitor->new($config);

# Start monitoring (endless loop, never returns)
$monitor->Loop();

The SNMP::Monitor module is a package for checking and watching arbitrary values via SNMP. Events can be triggered, Logging can be done, whatever you want.

The package is based on the SNMP package, but it is merely created for system administrators and not for programmers.

SNMP::Multi is a Perl module to perform SNMP operations on multiple hosts simultaneously.

SYNOPSIS

use SNMP::Multi;

my $req = SNMP::Multi::VarReq->new (
nonrepeaters => 1,
hosts => [ qw/ router1.my.com router2.my.com / ],
vars => [ [ sysUpTime ], [ ifInOctets ], [ ifOutOctets ] ],
);
die "VarReq: $SNMP::Multi::VarReq::errorn" unless $req;

my $sm = SNMP::Multi->new (
Method => bulkwalk,
MaxSessions => 32,
PduPacking => 16,
Community => public,
Version => 2c,
Timeout => 5,
Retries => 3,
UseNumeric => 1,
# Any additional options for SNMP::Session::new() ...
)
or die "$SNMP::Multi::errorn";

$sm->request($req) or die $sm->error;
my $resp = $sm->execute() or die "Execute: $SNMP::Multi::errorn";

print "Got response for ", (join , $resp->hostnames()), "n";
for my $host ($resp->hosts()) {

print "Results for $host: n";
for my $result ($host->results()) {
if ($result->error()) {
print "Error with $host: ", $result->error(), "n";
next;
}

print "Values for $host: ", (join , $result->values());
for my $varlist ($result->varlists()) {
print map { "t" . $_->fmt() . "n" } @$varlist;
}
print "n";
}
}

The SNMP::Multi package provides a mechanism to perform SNMP operations on several hosts simultaneously. SNMP::Multi builds on G. Marzots SNMP Perl interface to the UC-Davis SNMP libraries, using asynchronous SNMP operations to send queries/sets to multiple hosts simultaneously.

Results from all hosts are compiled into a single object, which offers methods to access the data in aggregate, or broken down by host or the individual request.

SNMP::Multi supports SNMP GET, SET, GETNEXT, GETBULK and BULKWALK requests. It also performs PDU packing in order to improve network efficiency, when packing is possible.

SNMP-Check project gets Host/Router information via snmp and displays it.

AdventNet SNMP Utilities offers a comprehensive development toolkit for SNMP-based network management applications. These tools can be used for device, element, application, and system management. The tools can communicate and interact with any SNMP-enabled device. Also it is very helpful for debugging and testing. The SNMP Utilities has a simple and intuitive graphic user interface that allows you to perform various functions in a mouse-click.
AdventNet SNMP Utilities provides off-the-shelf components for trap and table handling along with basic SNMP operations, such as SNMP GET, SNMP GETNEXT, SNMP GETBULK, and SNMP SET.
These tools can be used to manage SNMPv1, SNMPv2c, and SNMPv3 agents (i.e. the tools are multi-lingual) and talk to managed devices using any of the three versions of the SNMP protocols at the same time.AdventNet SNMP Utilities completely supports SNMPv3, as it is compliant with RFC 3411, 3412, 3413, 3414, and 3415. It also supports co-existence, notification filtering, and proxy forwarding; thus confirming to the RFC 2573 and 2576.
The following tools can communicate and interact with any SNMP-enabled device.

* MibBrowser - used to view and operate on data available through a SNMP agent on a managed device.
* SNMP Decoder - used to view the decoded output of the debug information.
* Trap Viewer - used to parse and view the received traps.
* Proxy Forwarder Configuration tool - tool for configuring USM user tables and VACM entries for SNMPv3 agent.
* WebServer and SAS Server - facilitates the use of SNMP management applets.
* Proxy Forwarder - used to translate SNMPv3 request for SNMPv1 and v2c agents.
* i18NEditor - used for internationalization.
MibBrowser and TrapViewer are available both as applications and applets. While the applications can be used as standalone executables, the applets can be remotely accessed via a web browser with the Java plug-in in any Java enabled web browser.

GKrellm SNMP Monitor project is a plugin for GKrellM that lets you easily monitor SNMP vars.

Some examples are server load via UCD-SNMP daemon or ambient temperature via router environment MIB.

SNMP Status monitors a SNMP device like AirPort routers and displays the traffic of a connected interface in the menubar.

Sometimes the SNMP "Community" is called "password". There is no
password is the Community "public". If the counters as producer-independent IF MIB objects or as Apples AIRPORT-BASESTATION-3-MIB are present select one the relevant interface over the names and the details are automatically filled out.
If the equipment manufacturer its own MIB used one must indicate the
counters numerically.

Whats New in This Release:

· Values have adjustable label, color and scale.
· Device selection detects Airport routers via Rendevouz.
