Probleme with an SNMP type

[Brice.F]

Hello,

Recently i configured zabbix in order to get some some SNMP data on an embed system. When i try to get an IPAddress Type Information (ex : 1.3.6.1.2.1.4.20.1.1.127.0.0.1), i obtain random information (ex: 0.0.0.0)

When i check sources i sawsomething strange in poller/checks_snmp.c line 350 :

			else if(vars->type == ASN_IPADDRESS)
			{
/*				ip = vars->val.string;
				snprintf(result_str,MAX_STRING_LEN-1,"%d.%d.%d.%d",ip[0],ip[1],ip[2],ip[3]);*/
/*				if(item->type == 0)
				{
					ret = NOTSUPPORTED;
				}*/
				if(item->value_type != ITEM_VALUE_TYPE_STR)
				{
					snprintf(error,MAX_STRING_LEN-1,"Cannot store SNMP string value (ASN_IPADDRESS) in item having numeric type");
					zabbix_log( LOG_LEVEL_ERR, error);
					SET_MSG_RESULT(value, strdup(error));
					ret = NOTSUPPORTED;
				}
				else
				{
					p = malloc(16);
					if(p)
					{
						snprintf(p,MAX_STRING_LEN-1,"%d.%d.%d.%d",ip[0],ip[1],ip[2],ip[3]);

						SET_STR_RESULT(value, p);
					}
					else
					{
						snprintf(error,MAX_STRING_LEN-1,"Cannot allocate required memory");
						zabbix_log( LOG_LEVEL_ERR, error);
						SET_MSG_RESULT(value, strdup(error));
					}
				}
			}

It seems that ip is never instanciate. What do you think? Is it normal?

Thanks for your help.

Sorry, I do not understand you question.

I want to poll an snmp value which type is "IpAddress" or ANS_IPADDRES. It displays random data (instead or receiving 127.0.0.1 i had 0.0.0.0 or worst).

I think that maybe zabbix_server don't poll Ip Address well. In source we have this :
snprintf(p,MAX_STRING_LEN-1,"%d.%d.%d.%d",ip[0],ip[1],ip[2],ip[3]);

But i don't see when ip var is intantiate. So before to submt a bug i want to know where it occurs. I hope it's clearer
