luasnmp not work with net-snmp 5.8, ubuntu 20.04 #1

Closed mendisobal closed 3 years ago

mendisobal commented 3 years ago

in exampes file walk.lua says: " unable to open session with netsnmp:"

hleuwer commented 3 years ago

My last release was for net-snmp 5.7. Did you compile and link against net-snmp 5.8 and did this work?

mendisobal commented 3 years ago

I am using net-snmp 5.8 included with ubuntu 20.04 deb package net-snmp. luasnmp compiled but didn't work. I would like to know what is needed for luasnmp to work with net-snmp 5.8

Hi, I have the same issue with samples on open() calls. The only error is "netsnmp:".

local snmp = require "snmp"
hub1, err = snmp.open{peer = "127.0.0.1", community = "public", version = SNMPv2c}
assert(hub1, err)

I'm using LUA 5.3, Net-SNMP 5.8 on Fedora.

I had the same issue with previous version 1.0.6 of luasnmp.

Fixed and upgraded to version 1.0.8 using net-snmp 5.9. Tested only on MacOs for now.
