I can speak only retrospectively of the school I was at in Dorset, of it
is of any use to you?

Why? Why would you want to "simulate" concurrent logins in that way?
What is it going to show, other than a (possibly) short lag in
authentication? What purpose does that show, other than to prove the
point that the server can handle it?

As Mark has pointed out, this is an interesting way of doing things.

Depends what you want to do.

I'd have said iptables.

See the thread Matthew and I discussed a few months ago (it's in the
archives). Exim/postfix/qmail are all powerful MTAs (Mail Transfer
Agent). SuSE still uses Sendmail as the default, I believe. But not that
it matters a greatr deal. If you really are gunning for choosing one, go
with Exim.

Note that an MTA is different for a MDA (Mail Delivery Agent) -- of which
you probably want to use Dovecot, which supports IMAP/Pop3 as protocols.
Out of the box (under Debian at least) it runs with IMAP, so you're OK,

Webmail? Squirremail should do you.

No such thing for Linux, although I assume you mean you want to scan
(audit?) your workstations? Clamav/SpamAsssassin can all be hooked into
your MTA.

> Remote Access [...suggestions please?]

Do you *really* want to provide ssh access? If so, there is winSCP for
the students, although seriously consider the risk involved in doing so.
There are web-based solutions via shit javascript interfaces out there --
which, although awful, do work.

> Configuration & management tools [...suggestions please?]

Vim. (Because you don't specify what you're after in terms of management
and configuration). Although I suspect you're wanting something along the
lines of {web,user}min [1]? Of course, it might be that YAST is all you

> Backup software [...suggestions please?]

Rsync? Rsync-diff? Will you be doing incremental backups? Will you be
backing up to tape? Will you want some kind of file-based mirroring
(intermezzo, for example). Will you want to just use cron and scp? What
do you want to backup? When?

Mutt. Thunderbird (shudder).

> Anti-virus (workstation) [...suggestions please?]

Under windows or Linux? If you mean the latter, there's no such thing.
If you mean the former, I couldn't say.

> Remote config & management tools [...suggestions please?]

Again, see {web,user}min [1]. My favourite is: ssh foo vim

[1] Don't get me started on either of those. I use them as examples
only. I don't suggest in anyway that you should use them.
