SNMPv3 with Cacti on Win2K3

[gattmandoo]

Hi all, I'm very new to Cacti and PHP. I have installed Cacti 0.8.7d on a Win2003 server. I am trying to get it working with SNMPv3. I have not been successful yet. I have the following installed.

Win2003
Cacti 0.8.7d
OpenSSL 0.9.8k light (32-bit)
NET-SNMP version: 5.4.1
PHP 5.2.10
RRDTool 1.2.x

When I add the device and set up the SNMPv3 info I always get "SNMP Error" I can go to a CMD prompt and do successfu snmpwalk and snmpget of the device using net-SNMP and SNMPv3 credentials

snmpget -v 3 -u user -l authPriv -a MD5 -A ******** -x DES -X ******** MYRouter 1.3.6.1.2.1.1.3.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (3990843558) 461 days, 21:40:35

but in Cacti SNMPv3 fails. SNMPv1/2 seem to work fine.
Any ideas?

1) wrong forum, moving.
2) search the windows forum, this has been covered many times. Windows does not support SNMPv3.

Correction, with the "latest" net-snmp you can download and install the OpenSSL support msi package (aka snmpv3). At that point in time, you have to disable PHP-SNMP support in PHP (aka php -m should not show snmp as a module, edit php.ini and search for extension...). You should then be able to perform snmpv3 with Windows by using the net-snmp binaries instead of the PHP Module.

I think the user is trying to enable snmpv3 support FOR windows -- not snmpv3 support IN cacti ON windows.

Thank for the replys but I figured it out.

You need to disable SNMP support in PHP which forces Cacti to use net-snmp for SNMPv3. As soon as I modified PHP and removed snmp settings it started working like a charm.

So all you need is OpenSSL and net-snmp on win2003 for snmpv3.

THanks,

Oh and you need to make sure you modify your windows environment variable MIBDIRS to point to your net-snmp mib directory
