SNMP.. on PC why oh why?

senget76 has asked for the wisdom of the Perl Monks concerning the following question:

Hi there

I just started playing with Net::SNMP
pretty cool stuff but I am trying to understand the OID
right now I am have 2 questions?

1. The example from Net::SNMP in www.cpan.org fail to get response from PC.. I wonder why, unix machine is fine and even any router but why PC give "NO reponse" error

2. I tried to find better way to understand OID.. id there any module available which contained OID without need to memorize the number eg. 1.3.6.X so on and so on
I really looking forward to hear any opinion

Thank you

Think of the OID as a tree like DNS most OID's in our world start Root->ISO(1)->Org(3)->dod(6)->internet(1)->private(4) which is the 1.3.6.1.4 then you add in the company specifics and get something like iso.org.dod.internet.private.enterpirises.cisco or 1.3.6.1.4.1.9 You can find a list of private enterprise numbers at ftp://ftp.isi.edu.in-note/iana/assigments/enterprise-numbers BTW chimni has given excellent advice above in recommending you pick up Essential SNMP it cleared up a bunch of the mud for me	[reply]

HI, Firstly i suggest you read a basic book on SNMP like O'reillys "SNMP Essentials" SNMP can work in 2 basic scenarios 1-SNMP GET 2-SNMP Traps Before you can do an SNMP get on a PC (im assumin you have winodws installed),you must configure the pc to be SNMP enabled 1-Run the service on the pc 2-If you want to send traps then name the destination server 3-Deal with your community strings Once you have done this ,maybe you could start with the Net::SNMP module.

The most likely reason that the PC (Windows) does not respond to SNMP is that the SNMP service is probably not installed. Micro$oft supplies SNMP with Windows NT and derivatives (on the OS install CD's) , but it is not installed by default - you can install it by going into the control panel -> add / remove programs -> Add/remove Windows components -> Management & Monitoring services (in XP) -> SNMP. You will need to configure the community strings - leave the default as "public", and do not enable WRITE, unless you know how that will be used. There are english-like equivalents for all OID's. You will have to find them by R'ing the FM. "When you are faced with a dilemma, might as well make dilemmanade. "	[reply]
