php : snmpwalk don't provide last entry

[Dominique Fournier]

Binary package hint: php5-snmp

Snmpwalk don't provide the last entry :
<?php
var_dump (snmpget ("1.1.1.4", "public@2", ".1.3.6.1.2.1.17.4.3.1.2.0.48.72.152.38.213"));
var_dump (snmpwalk ("1.1.1.4", "public@2", ".1.3.6.1.2.1.17.4.3.1.2.0.48.72.152.38.213"));
var_dump (snmprealwalk ("1.1.1.4", "public@2", ".1.3.6.1.2.1.17.4.3.1.2.0.48.72.152.38.213"));
?>
The result is :
string(11) "INTEGER: 68"
array(0) {
}
array(0) {
}
I have an answer on this OID : snmpwalk should give me 68 in the array, not empty, like snmpget do !
With system snmpwalk, it works well.

Can you give the expected result as well?

Thanks

The answer should be an array with one text entry "INTEGER: 68", like in
snmpget, not an empty array.

You can test with an easier OID 1.3.6.1.2.1.2.2.1.8.3 (it is the state
of interface #3). In this case, the answer should be an array with one
string entry
["IF-MIB::ifOperStatus.3"]=>
   string(14) "INTEGER: up(1)"
like you can see it if you test snmpwalk with 1.3.6.1.2.1.2.2.1.8

Thanks to look at that !

Is there anything in dmesg when this is happening. Maybe net-snmp segfaulting?

No log. Nothing wrong.

[Chuck Short (zulcss)]
