Hello Dave,
Thanks for your help, making me understand the man page a bit better now
for net-snmp.
Well my Perl script is ready and working fine with snmpwalk/
snmpgetnext/ snmpget. I am going to post the dummies how to on that. You
are welcome to make your comments on that. Here is the draft.
------------------------------------------------------------------------
---
Trying to create a simple perl script to query via snmp which replies
with recursively not just one set as shown on the main man page(you can
choose any others of your choice).
If is simple as long as basics are correct...
1. It should always reply with 3(three) sets of DATA
-> The OID
-> The Type (String or integer)
-> The Data
Example:
.1.3.6.1.4.1.9999.1.0.0
string
QAC_runtime
2. It should not print anything or debug message if there is anything
wrong it should just do an exit!!
3. The script should be able to answer to "-g" and "-n" option only when
that was passed otherwise do an exit.
4. When it is "-g" it should print the value for the OID it was asked.
Example:
# /usr/bin/lmstat.pl -g .1.3.6.1.4.1.9999.1.0.0
.1.3.6.1.4.1.9999.1.0.0
string
QAC_runtime
5. When it is "-n" it should print the value for the next OID, then it
was asked with.
Example:
# /usr/bin/lmstat.pl -n .1.3.6.1.4.1.9999.1.0.0
.1.3.6.1.4.1.9999.1.0.1
integer
0
6. When the last OID is reached it should exit. Like here I query the
parent OID and as soon I reach end I exit. This only can be done with
SNMP-WALK not by your script. As your script should only return the
first OID ".1.3.6.1.4.1.9999.1.0.0" when called with
".1.3.6.1.4.1.9999.1"
# /usr/local/net-snmp/bin/snmpwalk -v 1 -c public localhost
.1.3.6.1.4.1.9999.1
SNMPv2-SMI::enterprises.9999.1.0.0 = STRING: "QAC_runtime"
SNMPv2-SMI::enterprises.9999.1.0.1 = INTEGER: 0
SNMPv2-SMI::enterprises.9999.1.1.0 = STRING: "QAD_Planning"
SNMPv2-SMI::enterprises.9999.1.1.1 = INTEGER: 0
SNMPv2-SMI::enterprises.9999.1.2.0 = STRING: "948"
Like .....
....
------------------------- End of Draft ------------------------------
Hope this one helps some others.

Santanu

PASS-THROUGH CONTROL
pass MIBOID EXEC
EXEC -g MIBOID
EXEC -n MIBOID
To indicate that the script is unable to comply with the request
due to an end-of-mib condition or an invalid request, simply exit
and return no output to stdout at all.
^^^^^^^^^^^^^^^^^^^^^^^^^^
"wrong oid passed with option -n" is *NOT* the same as "no output"

Follow the instructions in snmpd.conf.
I'd also suggest you try testing with "snmpget" and
"snmpgetnext" rather than "snmpwalk"
