Few issues with luasnmp

Howdy:

Having a problem. I need to use snmpset in lua, so I use the luasnmp module.

I just want to perform remote pings via snmpset (get snmpd to respond to DISMAN-PING-MIB

requests). However, I am having issue after issue with lua which is very frustrating. OK, by going

through a lot of aggravation searching stuff out on the web and reading code, I have a sort of

working snmp and a script that works.

My present problem is that when I perform this script to snmpset a cisco device it works well, but failed on a h3c(chinese company) device

and get one error message that say : " snmp: timeout ". But it is ok by using net-snmp snmpset with bash shell.

Has someone who can handle it for me? Or give me any experience (or advice / where I should look) with this ? Thanks!

Here is part of the script:

local snmp = require "snmp"

hub1, err = snmp.open{

peer = "destinationip",

community = "private",

}

assert(hub1, err)

vbIn = {

{oid = ".1.3.6.1.4.1.9.9.16.1.1.1.16.333", type = snmp.TYPE_INTEGER, value = 6 }, -- CISCO-PING-MIB works fine on a cisco device

-- {oid = ".1.3.6.1.2.1.80.1.2.1.23.4.116.101.115.116.1.50", type = snmp.TYPE_INTEGER, value = 4 }, -- DISMAN-PING-MIB don't work on a h3c device

}

vbOut, err = assert(hub1:set(vbIn))

But it works well when I enter this command in bash shell:

snmpset -v 2c -c private destinationip .1.3.6.1.2.1.80.1.2.1.23.4.116.101.115.116.1.50 i 4

then return this " SNMPv2-SMI::mib-2.80.1.2.1.23.4.116.101.115.116.1.50 = INTEGER: 4 "
