Cacti does not recognise snmp v3 community string

[m_spidey]

Hello All

I recently migrated my cacti host from a solaris machine to a Linux machine (Gentoo). Everything went smoothly but just today I realised that the new Gentoo machine is not graphing the right values.

I had it set up so that all the snmp queries went to one machine and depending on the community string specified the machine would then go and fetch the required data. So in essence I had a snmp proxy. On the old solaris machine everything went relatively smoothly all the values were from the right machine. But on this new Gentoo machine I just realised that all the hosts that are monitored through the community string are all returning the same value as first machine its querying. Its as if the community string is ignored completely.

EDIT: Oh I forgot to add before that I changed the snmpauth line from

$snmp_auth = "-u $username -l authNoPriv -a MD5 -A $password";

$snmp_auth = "-n $community -u $username -l authPriv -a MD5 -A $password -x DES -X $password"; /* v3 - username/password */

This might be a really stupid test but then I changed the community string to something invalid and it still returned the same original value. Is this the expected behaviour? Does any know of an answer to my question ?

Thanks in advance.

Cheers
