Fixed Cacti not displaying interfaces for HP 1810G switch

While implementing a new network for a customer, we took an existing HP 1810G 48-port switch under management. As per normal, we setup monitoring (Icinga) and graphing (Cacti), but while the switch responded to Cacti sysname polls (leading us to believe it was happy), it didn’t return any interface details, so we weren’t able to graph anything.

Workaround for the Cacti segmentation fault on CentOS5

Seems a little dumb, and I’m not sure how other distributions deal with it, but if you install Cacti from RPM on CentOS, and then browse to your /cacti/ directory via HTTP, you’ll find that it dies with a segmentation fault. You know this is you if every other website on your host works, but everytime you go to your /cacti/ URL, your browser reports that the site is totally unavailable (as if apache weren’t even running).
