Inherited FreeBSD machine without: firewall, proxy (i.e. squid) and RAID management

[Jeremiah Foster]

Good morning list,

The company I work for has brought some web serving in-house. We now
have a machine from a subcontractor that is running FreeBSD 4.11. It is
a production web server responsible for generating data from the
database and presenting it (in Zope, yuck.)

I would like to create a firewall, add caching so that the web pages get
served more quickly, and find out when the RAID disks are failing, right
now I can tell when that happens because the database slows to a crawl.

Does anyone have any advice?

I am aware of excellent FreeBSD firewalling software which I will most
likely use. I am also familiar with squid - is this my best be for
caching web pages so that the site appears to load faster? I can see
from dmesg.boot that the relevant RAID aparatus is a <COMPAQ RAID 1
VOLUME inte> Fixed Direct Access SCSI-0 device, what would be the right
software to monitor this volume? Obviously not vinum since I have been
informed that it is a software RAID management system, not hardware
management.

Thank you very much,

Jeremiah Foster
