#23685 [Opn]: fake values returned when OID value is an empty string

ID: 23685 User updated by: s dot zagrodzki at net dot icm dot edu dot pl Reported By: s dot zagrodzki at net dot icm dot edu dot pl Status: Open Bug Type: SNMP related Operating System: Linux 2.2 PHP Version: 4.3.2RC4-dev New Comment: I tried using snmp module from 20030714 snapshot - didn't help. Previous Comments: ------------------------------------------------------------------------ [2003-07-14 02:35:43] s dot zagrodzki at net dot icm dot edu dot pl this is a part of tcpdump of snmpwalk query: ... GetResponse(50) .1.3.6.1.2.1.31.1.1.1.18.3="lacze do Obs. Astr." GetNextRequest(31) .1.3.6.1.2.1.31.1.1.1.18.3 GetResponse(31) .1.3.6.1.2.1.31.1.1.1.18.4="" GetNextRequest(31) .1.3.6.1.2.1.31.1.1.1.18.4 GetResponse(59) .1.3.6.1.2.1.31.1.1.1.18.5=": lacze do Wydz. Zarzadzania" ... as you can see, snmp agent returns empty value, response length is also correct. And snmpwalk utility also gives correct results. ------------------------------------------------------------------------ [2003-07-13 14:49:20] harrie@php.net I tried this with other variables (I do not have an SNMP agent implementing the ifXTable) and cannot reproduce it. Therefore I am thinking that it maybe the SNMP agent which returns these values and as a result they show up in PHP. Could you confirm that this is not a problem with the SNMP agent/router. ------------------------------------------------------------------------ [2003-07-13 00:11:43] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Some changes have been made lately. ------------------------------------------------------------------------ [2003-05-19 04:30:19] s dot zagrodzki at net dot icm dot edu dot pl I've copied ext/snmp directory from this snapshot into my php source tree (when I tried to compile the snap as it is, it complained about too old db3 library). It didn't help. ------------------------------------------------------------------------ [2003-05-18 16:57:47] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
