No output from mib2c compiled MIB
Hey dude!
I am working on a 64 bit system for which I need to know its
diagnostics. Like array status, cpu temp, hard drive status, temp
etc.
What I have done is I have written a new MIB for that system which is
error free [I checked it through snmpB mib editor].
Then I produced the 2 files[.h & .c] through mib2c script provided
along with net-snmp 5.4.2.1 which are required to compile with new mib
modules.
Then I built the net-snmp package from the source using the option ./
configure --with-mib-modules and edited the snmpd.conf file as per
need.
Its reading my MIB and snmpwalk returns me some default values. for
example:
[root@vik local]# snmpwalk -v2c -c myco localhost .1.3.6.1.4.1.myoid
SNMPv2-SMI::enterprises.myoid.1.1.2.2.1.1.1.2.0 = INTEGER: 0
SNMPv2-SMI::enterprises.myoid.1.1.2.2.1.1.1.3.0 = INTEGER: 0
SNMPv2-SMI::enterprises.myoid.1.1.2.2.1.1.1.4.0 = INTEGER: 0
SNMPv2-SMI::enterprises.myoid.1.1.2.2.1.1.1.5.0 = INTEGER: 0
SNMPv2-SMI::enterprises.myoid.1.1.2.2.1.1.1.6.0 = INTEGER: 0
SNMPv2-SMI::enterprises.myoid.1.1.2.2.1.1.1.7.0 = INTEGER: 0
It looks like I have to add some code in the .c & .h file but I am not sure what it is?
Also I am using python scripts to retrieve the diagnostics, since its the external program I think I can pass the OIDs along with the script name & path in the snmpd.conf file.
It looks like if you are using an externam programme then u dnt need to compile it thru mib2c.
I am not sure as whats happening in there...
Anyways please reply if you have any information.
Thanks
Vik

net-snmp-config
net-snmp-config(1) Net-SNMP net-snmp-config(1)
NAME
net-snmp-config - returns information about installed net-snmp libraries and binaries
SYNOPSIS
net-snmp-config [OPTIONS]
DESCRIPTION
The net-snmp-config shell script is designed to retrieve the configuration information about the libraries and binaries dealing with the
Simple Network Management Protocol (SNMP), built from the net-snmp source package. The information is particularily useful for applications
that need to link against the SNMP libraries and hence must know about any other libraries that must be linked in as well.
OPTIONS
--version
displays the net-snmp version number
--indent-options
displays the indent options from the Coding Style
--debug-tokens
displays a example command line to search to source code for a list of available debug tokens
SNMP Setup commands:
--create-snmpv3-user [-ro] [-a authpass] [-x privpass] [-X DES|AES]
[-A MD5|SHA] [username]
These options produce the various compilation flags needed when building external SNMP applications:
--base-cflags
lists additional compilation flags needed for external applications (excludes -I. and extra developer warning flags, if any)
--cflags
lists additional compilation flags needed
--libs lists libraries needed for building applications
--agent-libs
lists libraries needed for building subagents
--netsnmp-libs
lists netsnmp specific libraries
--external-libs
lists libraries needed by netsnmp libs
--netsnmp-agent-libs
lists netsnmp specific agent libraries
--external-agent-libs lists libraries needed by netsnmp libs
Automated subagent building (produces an OUTPUTNAME binary file): [This feature has not been extensively tested, use at your own risk.]
--compile-subagent OUTPUTNAME [--norm] [--cflags flags]
[--ldflags flags] mibmodule1.c [...]]
--norm leave the generated .c file around to read.
--cflags flags
extra cflags to use (e.g. -I...).
--ldflags flags
extra ld flags to use (e.g. -L... -l...).
Details on how the net-nsmp package was compiled:
--configure-options
Display original configure arguments
--snmpd-module-list
Display the modules compiled into the agent
--prefix
Display the installation prefix
