Hi Together,
i implemented a program which receives SNMP-Traps from each source and prints
the oid and the value of the trap.
My problem is to get the ip-address from the source which sends the trap.
Here are two functions which I call in main() to receive and print the traps:
int my_asynch_response(int operation, struct snmp_session *sp, int reqid,
struct snmp_pdu *pdu, void *magic) {
char buf[1024];
struct variable_list *vp;
int ix;
struct timeval now;
struct timezone tz;
struct tm *tm;
struct snmp_pdu *req;
printf("\nGot the message!! Trying to sent it out again\n");
if (operation == NETSNMP_CALLBACK_OP_RECEIVED_MESSAGE) {
print_result(STAT_SUCCESS, sp , pdu);
}
return 0;
}
/* simple printing of returned data
*/
int print_result (int status, struct snmp_session *sp, struct snmp_pdu *pdu)
{
char buf[1024];
struct variable_list *vp;
int ix;
struct timeval now;
struct timezone tz;
struct tm *tm;
gettimeofday(&now, &tz);
tm = localtime(&now.tv_sec);
//fprintf(stdout, "%.2d:%.2d:%.2d.%.6d ", tm->tm_hour, tm->tm_min, tm->tm_sec,
// now.tv_usec);
switch (status) {
case STAT_SUCCESS:
vp = pdu->variables;
if (pdu->errstat == SNMP_ERR_NOERROR) {
while (vp) {
// PRINT ALLES
//snprint_variable(buf, sizeof(buf), vp->name, vp->name_length, vp);
// PRINT ONLY OIDs
snprint_objid(buf, sizeof(buf), vp->name, vp->name_length);
fprintf(stdout, "%s\n", buf);
snprint_value(buf, sizeof(buf), vp->name, vp->name_length, vp);
fprintf(stdout, "%s\n" , buf);
vp = vp->next_variable;
}
}
else {
for (ix = 1; vp && ix != pdu->errindex; vp = vp->next_variable, ix++)
;
if (vp) snprint_objid(buf, sizeof(buf), vp->name, vp->name_length);
else strcpy(buf, "(none)");
fprintf(stdout, "%s: %s: %s\n",
sp->peername, buf, snmp_errstring(pdu->errstat));
}
return 1;
case STAT_TIMEOUT:
fprintf(stdout, "%s: Timeout\n", sp->peername);
return 0;
case STAT_ERROR:
snmp_perror(sp->peername);
return 0;
}
return 0;
}
