[game-game 0]

selamat pagi semua..

actually aku nk tanye, snmp ni dalam kategori ape dalam subtopic2 dalam ebooks? dalam network? aku tak jmpe kat ctu..

sape2 tau tak? bagi example paling ringkas pon takpe.. aku cme nak tngok ape command die je.. cam get request, trap ke..

sebagai permulaan - http://en.wikipedia.org/wiki/Simple_Networ...gement_Protocol. Tapi lebih baik lagi kalau baca relevan RFCs.

http://www.net-snmp.org/ kalau awak nak open source SNMP library (C or perl).

thanks untuk info tu.. aku ade jmpe satu coding ni

#include <net-snmp/net-snmp-config.h>

#include <net-snmp/net-snmp-includes.h>

#include <string.h>

int main(int argc, char ** argv)

{

struct snmp_session session;

struct snmp_session *sess_handle;

struct snmp_pdu *pdu;

struct snmp_pdu *response;

struct variable_list *vars;

oid id_oid[MAX_OID_LEN];

oid serial_oid[MAX_OID_LEN];

size_t id_len = MAX_OID_LEN;

size_t serial_len = MAX_OID_LEN;

int status;

struct tree * mib_tree;

/*********************/

if(argv[1] == NULL){

printf("Please supply a hostname\n");

exit(1);

}

init_snmp("APC Check");

snmp_sess_init( &session );

session.version = SNMP_VERSION_1;

session.community = "public";

session.community_len = strlen(session.community);

session.peername = argv[1];

sess_handle = snmp_open(&session);

add_mibdir(".");

mib_tree = read_mib("PowerNet-MIB.txt");

pdu = snmp_pdu_create(SNMP_MSG_GET);

read_objid("PowerNet-MIB::upsBasicIdentModel.0", id_oid, &id_len);

snmp_add_null_var(pdu, id_oid, id_len);

read_objid("PowerNet-MIB::upsAdvIdentSerialNumber.0", serial_oid, &serial_len);

snmp_add_null_var(pdu, serial_oid, serial_len);

status = snmp_synch_response(sess_handle, pdu, &response);

for(vars = response->variables; vars; vars = vars->next_variable)

print_value(vars->name, vars->name_length, vars);

snmp_free_pdu(response);

snmp_close(sess_handle);

return (0);

}

ble aku run,

gcc 'net-snmp-config --cflags' 'net-snmp-config --libs''net-snmp-config --external-libs' snmp_test.c -o snmp_test

die cakap,

kenape ek? aku dah install net-snmp ni..

untuk mkluman korang, aku refer guide ni...The Cuddletech Guide to SNMP Programming
