Restriction for PHP version.
- up to PHP 4.3.x some functions do not function because of classes and refences are not always compatible to PHP5.x and above.
- for PHP 4.x some functions do not function if you are not using NET-SNMP. For example TFTP download/upload of CAToS (not IOS) need the function snmpnext which is not in PHP 4.4
- PHP 5.x no problem encoutered until now.

Vendors:
I cannot test all vendors, I have programmed some like a "blind"-man.
Therefore I need also your feedback (http://cactiusers.org/forums/topic257.html or http://forums.cacti.net/about12406.html).
