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

snmp-bridge-mib
SNMP-BRIDGE-MIB(1) Net-SNMP SNMP-BRIDGE-MIB(1)
NAME
snmp-bridge-mib - provide Linux bridge information via SNMP
SYNOPSIS
snmp-bridge-mib {bridge}
ARGUMENTS
The following arguments are required:
bridge
The name of the Linux bridge for which you want to provide information via SNMP, e.g. br0.
DESCRIPTION
The snmp-bridge-mib is an extension to net-snmp. It collects information about a bridge in a Linux system and exports them for query from
other (remote) systems for management purposes.
CONFIGURATION
:
The preferred method of snmp-bridge-mib to attach to net-snmp is agentx. For this to work, you will have to add the following line to
/etc/snmp/snmpd.conf,
master agentx
restart snmpd and start snmp-bridge-mib. snmp-bridge-mib will then connect to the running snmpd daemon.
Another way of attaching snmp-bridge-mib to is to run it as an embedded perl module. You have to add
perl do "path to location of snmp-bridge-mib"
and restart snmpd.
EXAMPLE
:
Follow the instructions in this manpage and type
perl /usr/bin/snmp-bridge-mib br0
You'll get the following output:
registering at .1.3.6.1.2.1.17
running as a subagent.
dot1qbridge agent started.
NET-SNMP version 5.4.2.1 AgentX subagent connected
Now it's time for a first test:
$ export MIBS=+BRIDGE-MIB
$ snmpwalk localhost .1.3.6.1.2.1.17
The output produced should look like
BRIDGE-MIB::dot1dStpBridgeHelloTime = INTEGER: 199 centi-seconds

BRIDGE-MIB::dot1dTpPortInDiscards.1 = Counter32: 0 frames
BRIDGE-MIB::dot1dTpPortInDiscards.3 = Counter32: 0 frames
BUGS
1. snmp-bridge-mib currently only supports one bridge which has to be specified on the commandline.
2. Not all elements of RFC 4188 because they are either not available in sysfs or difficult to extract from the existing data.
