Apparently the folks over at HQ have just implemented a new technology 
known as "home folders" - and it's planned that this idea will be rolled 
out at all sites in the near future.

Oh, wait a sec... we've had that in the UK for the last 6 years. Oh well.

[Seriously... WTF?! The more I work here, the more I wonder just what 
the hell they're *doing* at the other sites. This is pretty basic stuff...]

  Are those "home folders" somehow different from standard unix home
directories, an idea which has existed probably for over 30 years?

Erm... Well, they exist on a network filesystem... Nope, that's about 
the only thing I can think of that makes them in any way different...

[Also amusing was the "If you have anything on C:, please move it to 
your new home folder so we can back it up".]

  There's nothing stopping unix home directories from residing in a
network file system, and in fact that's a very common practice in
multiuser environments.

Well, originally I'm told it was on the local file system - but either 
way, it's a pretty tiny difference.

Also, the new AV software we're rolling out is configured to look for 
updates once per hour. Seriously. Once per hour. I don't know about 
Trend, but Symantec only release updates weekly. Daily if there's a 
serious outbreak. Hourly update checks?? Are you mental?!

Similarly, I just spoke to a user who got 137 emails this weekend 
telling her that she has exceeded her mailbox allocation. OK, so we want 
people to keep their mailbox size down. But 137 emails? Anyway, I 
emailled the server admin, and he changed the notification frequency 
from 1 hour to 4 hours.

Are you seeing a pattern here? Seriously... an email stays there until 
you read it. Why on earth do you need an email every 4 hours to remind 
you to do something? This is silly! Surely daily would be plenty...

I think ours (Sophos) is configured for once-per-hour too.  Why not?  I 
suspect only a very small amount of badnwidth is used up to check if an 
update is available, but the benefits could be huge if a serious virus gets 
into your network somehow.

On the odd occasion that I email (or at least cc) a senior manager in our 
company, there's probably a 50-75% chance that you'll get a message back 
saying their mail-box is full.  Great way to run a company...

Except you may not know when it gets released. A new virus is found, the  
AV boys crank out an update at 13:00; but you don't get it until 23:00  
'cos that's when you've set your system to check for updates. You're

Dear Customer,

Ooo, 4 hours. Big deal...

[I would think it takes a tad more than 4 hours for the AV company to 
even notice there's a new virus spreading, much less perform an 
extensive analysis and write a fix. And let us not forget, having the AV 
signatures is a *cure*, not a prevention.]

It works a bit differently on Windows. For example, it's the remote 
machine that checks you have permission to read your "home" directory 
instead of the local machine. (Dunno about other UNIX mounting systems, 
but NFS doesn't work that way.)  Plus, the directory gets mounted when 
you log in and dismounted when you log out, because Windows actually has 
network locking semantics for files. And, for example, Windows allows 
some home directories to be mounted locally, others to be mounted 
remotely on a variety of file servers, and there has to be some 
mechanism to tell the "client" machine which is where.

But conceptually, yeah, it's network-mounted home directories. The 
implementation is just harder to support the more complex file semantics 
Windows supports.

  I think at least some unix networked file systems support something
similar to this. Typically if you list the contents of /home you will only
see your own home directory and nobody else's. If you explicitly 'cd' to
someone else's home directory (if it's allowed) it will appear under /home.

  I don't know enough about file systems to be sure, but I would be
surprised if this wasn't supported by any unix networked file system.

A virus can do a lot of damage to a company in 4 hours... (isn't 23-13 10 
hours anyway? - oh maybe you shut your machines down at 17:00, but then how 
will they update at 23:00??)

If you have on-access scanning enabled, then it prevents you running any 
virus code that it knows about...

Yes. But if the updates only appear once every 24 hours, doing zillions 
of update checks per day is really quite futile.

The cycle goes like this:

1. Destructive virus is released.

2. It takes 72 hours for any AV companies to even notice it exists, much 
less obtain a useable sample for analysis.

3. It takes another 72 hours to analyse the virus and develop a virus 
definition for it.

4. The new definition is deployed.

5. Our server downloads and applies the definition.

My point is, that's 144 hours between the virus being released and the 
virus definition being released. An extra 24 hours before the server 
picks up the new definition seems quite trivial by conparison. The virus 
has already had plenty of time to wreck your entire network, long before 
the AV vendor has anything to offer you...

Considering how nasty some viruses can be these days, why take the risk? 24
hours could be the difference between one machine has it and the entire
network has it. And you're not necessarily going to get infected the instant
the virus comes out.

Update checks are very quick. Why not do one an hour?

Well, hey, why not do one an minute? Or even better, once per second?

Or one machine (server-type machine) hits the internet site and download the
definition. All the other machines retrieve the definition from the local
source.

Do all your machines get patches straight from the internet as well?

Agreed. So it becomes a question of where you [subjectively] percieve 
that point to be.

Personally, I have always had it set to update once per day, since our 
supplier only releases updates once per week and I want to be able to 
control exactly when all the PCs on our network will slow to a crawl for 
20 minutes. I don't actually know how frequently or not Trend Micro 
release them...

Indeed, this would be the optimal solution.

Currently yes. Hopefully that will be rectified eventually.

Probably not, as I doubt the person who released the virus aimed it straight 
at your network.  Likely it took several days to build up worldwide before 
it got into your network somehow.

Try having just one machine check and download the updates, then deal them 
out to everyone on your network.  That's how we do it here, as you say, 
seems kinda stupid to have all your machines all downloading the same 
software from the same place the whole time, especially with a limited 
network link.

Maybe you'll be unlucky. Most likely you won't. Either way, shaving 4 
hours off the window of opportunity seems a little moot when the window 
is theoretically hundreds of hours wide to start with, that's all.

Yes, our current solution does that, and hopefully the new software will 
eventually be configured that way too. (It requires updating a server to 
a newer version of Windows.)

As I said to Gail, our current AV solution tries to update once per day, 
which is 7x more often than the actual update release frequency. Seems 
fine to me. I don't know how often (if at all) our new provider releases 
these things...

What? You *aren't* using a proxy so that the updates are only downloaded 
once from the AV site and then transferred only via LAN??

Do you think the same about deadlines? "We won't make it in time anyway, 
so why even try?" Or the opposite: "We have plenty of time, so even 
though we have an (easy) way to take 4 hours less, why bother?":

Yes. How I saw it done, however, required the configuration to be on 
each client machine, rather than being maintained strictly at the 
server. Maybe it's similar in Windows, too, tho.

Given the flexibility of UNIX in general and Linux in particular, tho, 
I'm sure any problems could be worked around without much difficulty, 
for some size company. For example, I can't imagine Google has to do 
anything to bring up a new machine beyond booting a particular CD or 
something. :-)

I think it's more just a question of how complex a configuration you can 
specify, and not something to do with the file system as such. (Unless 
you want to have multiple home directories mounted at once, in the same 
directory, from different servers, of course.)

The main difference, I think, is that since you can't easily do 
something that isn't built in to Windows, Microsoft puts more options in 
obvious places in Windows than any given distribution of UNIX-like 
systems does. But since Linux (et al) is more open, it's probably easier 
to make it work *exactly* like you want it to. (And I think this 
analysis applies to many, many aspects of those systems, too.)

BOCTAOE.

  *Everything* in Unix is a file. Unix *is* a file manager OS. Anything
you can imagine you could do with files and directories, is possible
in unix, if by nothing else, by a little programming.

  I hear it's not even that hard to create your own file system driver
in unix (or at least linux). A friend of mine has written one which can
be used to create and mount compressed read-only file systems (with awesome
compression ratios).

The worst virus out there are made to target one or only a few companies. They 
are made to remain under the AV radars by limiting ther diffusion.
Very slow propagation to keep a minimal network impact. Very few machines 
infected every day or weeks, with a relatively low stop therhold. But, as they 
target juicy targets, the payof can be prety impressive.

I'm not sure what you're trying to express here. I meant that in the 
UNIX setups I've seen with distributed sharing of home directories off a 
central server, there's a bunch of information that has to be configured 
at each client to make it work. I.e., if I want to log in with my home 
directory on *this* client machine, I have to configure *this* client 
machine to know where *my* directory is, rather than just point the 
entire machine at the right server.

And what I was trying to express is "that's a pretty small problem to 
solve in UNIX, if it bothers you."

For all I know, it's already been solved.

Not quite, but pretty close, ya. Not quite everything is a file, or you 
wouldn't need other system calls. :-) The Amiga actually came much 
closer to making everything a file than UNIX ever did.

Nor is it in Windows. Not sure what the point is.

(I already agreed it's not much of a problem. It's just one I've never 
seen solved in a general way in UNIX. Maybe it is. :-)

I am still surprised that I never saw (say) the DBase company get in 
trouble for writing a virus that only messed up FoxBase data files or 
something. :-)

Not yet, no. (Requires a newer version of Windows on the server.)

I would guess that all that has to be done for
them is to set the BIOS to boot off the network.

Yeah, exactly. And given that I read they bought something like 15% of 
all servers manufactured last year, they can probably get custom BIOSes 
already set up for it put in the machine when they buy it.
