Free v2c software for linux

libksnmp is a KDE library that wraps around net-snmp to allow KDE applications to get SNMP statistics without the need to walk through net-snmp conflicts with autoconf/automake projects, using a KDEish C++ interface.

This library was initially wrote for my ATMOSphere project to simplify access ot SNMP statistics for routers compliant with this protocol.

Its just a wrapper around net-snmp, which does all the dirt work in a C way.
Also, this library is useful to avoid hacking around net-snmp "bugs" (or "features") with autoconf headers.

At the moment libksnmp can be used to access v1 and v2c compatible devices, in readonly way, with a simplified access to RFC1213-compliant devices.

For information on use of the library, please generate the doxygen apidoc, and
read it.

This is an experimental library for now, every contribution is well accepted,
if you want a CVS access to hack around, just contact me.

check_aus is a software that can check the status of a AUS device by snmp.

Usage:

usage:
-H (--hostname) Hostname to query - (required)
-C (--community) SNMP read community (defaults to public,
used with SNMP v1 and v2c
-v (--snmp_version) 1 for SNMP v1 (default)
2 for SNMP v2c
SNMP v2c will use get_bulk for less overhead
3 for SNMPv3 (requires -U option)
-p (--port) SNMP port (default 161)
-L (--seclevel) choice of "noAuthNoPriv", "authNoPriv", or "authPriv"
-U (--secname) username for SNMPv3 context
-c (--context) SNMPv3 context name (default is empty string)
-A (--authpass) authentication password (cleartext ascii or localized key
in hex with 0x prefix generated by using "snmpkey" utility
auth password and authEngineID
-a (--authproto) Authentication protocol ( MD5 or SHA1)
-X (--privpass) privacy password (cleartext ascii or localized key
in hex with 0x prefix generated by using "snmpkey" utility
privacy password and authEngineID
-M (--maxmsgsize) Max message size - usefull only for v1 or v2c
-t (--timeout) seconds before the plugin times out (default=15)
-V (--version) Plugin version
-h (--help) usage help

retrieve data section:
global community community
set the default community
the default unsetted is public

global inter seconds
set the default interval among two snmp get
the default unsetted is 300

global retry number
set the default number of retry
the default unsetted is 0

global timeout seconds
set the default request timeout (in seconds)
the default unsetted is 3

global version (v1|v2|v2c)
set the default snmp protocol version
the default value unsetted is v1

set
the keyword "set" set a snmp host server:

example:
set version v2c ip 192.168.10.4 timeout 3 retry 2 community public

the option are:

* ip server ip (must informed)
inter interval among two snmp get (default: "global inter")
version snmp protocol version (default: "global version")
timeout request timeout (default: "global timeout")
retry number of retry (default: "global retry")
community community (default: "global community")
( * ) must informed
get
the "get" keyword is used for declaring one snmp value:

example:
get oid IF-MIB::ifInOctets.3 inter 5 file toto type gauge

the option are:
* oid SNMPv2-MIB::sysDescr.0 the oid (must informed)
inter interval among two snmp get (default: inherited from the last set)
file the db rrdtool file (default: automaticaly generated)
type gauge type of rrdtool data (gauge, counter) (default: gauge)
timeout request timeout (default: inherited from the last set)
retry number of retry (default: inherited from the last set)
( * ) must informed
