[Debian-uk] OT: What's required for a debian based small business server?

[Joel Merrick]

With the advent of Vista and all the bells and whistles that it
provides, one can't help think that a lot of this functionality is
grossly overkill for a small business environment. I've not actually
checked how SBS2003 will develop, but I'm sure that it will continue
to tow the glitzier line

Myself and a friend are looking to create a debian based system that
contains some of the details what are listed below, but presented in a
fashion that is easy for the end user to understand (even easier than
webmin!). You see, to some end user I've shown webmin to, they've
completely understood the concept, but still lacked some of the
technical capability to properly use it and configure their servers as
needed.

Anyway, here is some of the list that we are thinking about implementing:

* Caching DNS Server
* DHCP Server
* Iptables firewall / NAT
* Content filtering
* Local intranet CMS - LAMP-based
* Shared wiki and / or blogs
* Groupware
* Email server
* Shared calendars
* Spam scanning with mgmnt
* LDAP directory server
* A/V - clamd
* Database server - Mysql
* Jabber server
* SAMBA File-server
* Client auth for Lin / Win clients
* Remote mounted home directories
* Printer sharing for Lin / Win clients
* Terminal Services?

I realize that these are a lot of services, so let's boil them down to
a few essential services

* File sharing
* Print sharing
* Email
* 'Clean' Internet access to other LAN machines.

What I'd be interested in knowing, is people's experience of such
small business environments. How much certain aspects are used=85 such
as how much groupware is used etc..

I'm sure that these are pretty open ended questions with even more
open ended answers, but any input would be most welcome

Thanks!
