SNMP protocol in Logic Machine

[admin]

Use this code to walk through SNMP:

Code:

function walk(peer, community, version, root)   local snmp = require('snmp')   local session, err = snmp.open({     peer = peer,     community = community or 'public',     version = version or snmp.SNMPv1   })   if not session then     return nil, 'unable to open session: ' .. tostring(err)   end   root = root or '1'   local vb = { oid = root }   local err   local res = {}   while true do     vb, err = session:getnext(vb)     if err then       break     elseif string.find(vb.oid, root) == nil or vb.type == snmp.ENDOFMIBVIEW then       break     else       res[ vb.oid ] = vb.value     end   end   session:close()   if err then     return nil, 'walk failed: ' .. tostring(err)   else     return res   end end res, err = walk('192.168.1.1', 'public', snmp.SNMPv1, '1.0.8802.1.1.2.1.3') log(res, err)

Arguments for walk:
1. remote device IP
2. community, defaults to 'public'
3. version, defaults to v1
