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

NAME
snmp - cups snmp backend
SYNOPSIS
/usr/lib/cups/backend/snmp ip-address-or-hostname
/usr/libexec/cups/backend/snmp ip-address-or-hostname
lpinfo -v --include-schemes snmp
DESCRIPTION
The CUPS SNMP backend provides legacy discovery and identification of network printers using SNMPv1. When used for discovery through the
scheduler, the backend will list all printers that respond to a broadcast SNMPv1 query with the "public" community name. Additional queries
are then sent to printers that respond in order to determine the correct device URI, make and model, and other information needed for
printing.
In the first form, the SNMP backend is run directly by the user to look up the device URI and other information when you have an IP address
or hostname. This can be used for programs that need to configure print queues where the user has supplied an address but nothing else.
In the second form, the SNMP backend is run indirectly using the lpinfo(8) command. The output provides all printers detected via SNMP on
the configured broadcast addresses. Note: no broadcast addresses are configured by default.
MIBS
The CUPS SNMP backend uses the information from the Host, Printer, and Port Monitor MIBs along with some vendor private MIBs and intelli-
gent port probes to determine the correct device URI and make and model for each printer.
CONFIGURATION
The SNMP backend reads the /etc/cups/snmp.conf configuration file, if present, to set the default broadcast address, community name, and
logging level. The configuration file is documented in cups-snmp.conf(5). The DebugLevel value can be overridden using the CUPS_DEBUG_LEVEL
environment variable and the MaxRunTime value can be overridden using the CUPS_MAX_RUN_TIME environment variable.
