A full definition of this session can be found in the net-snmp/snmp_api.h header file.

Next, we'll initialize a session that describes who we want to talk to, what version of SNMP we want to use, how to authenticate to it, etc. Then, the first thing we must do is to initialize the snmp library:

struct variable_list: This will hold the variables that we want to manipulate via SNMP.

oid: An OID is going to hold the location of the information which we want to retrieve.

We'll declare a second for the information that they are going to send back.

struct snmp_pdu: This structure will hold all of the information that we're going to send to the remote host.

We need to declare 2 of these, one to fill with information, and second which is a pointer returned by the library.

struct snmp_session: A structure that holds information about who we're going to be talking to.

Next, we declare our main() routine and the variables we need: * change the word "define" to "undef" to try the (insecure) SNMPv1 version */Ĭonst char *our_v3_passphrase = "The Net-SNMP Demo Password" If you don't want to deal with SNMPv3 for now, turn the #define statement below to #undef. By default, we're setting up for SNMPv3 here (which is more complex) so make sure you've read about the SNMPv3 Options first. Next, we'll set up some local definitions that you can toggle if you want to use SNMPv3 or SNMPv1. We start our snmpdemoapp.c file with these: After you've installed the net-snmp toolkit, some easy to use header files have been installed that handle most situations you'll run into.
