NAS and legacy FSFD

A customer has been using our legacy FSFD successfully on XP Pro mapped to a
remote drive… When the remote drive was replaced with a NAS (Network
Attached Storage), all of the sudden the filter is not seeing the file
activity. Is there something special I should know about filtering NAS
devices?

Thanks

Find out what CIFS server it’s running (i.e. samba or something
proprietary). It would be something of an understatement to say that
Samba emulates Windows imperfectly. For what it’s worth, I’m pretty
sure NetApp has a proprietary CIFS server, but I’d bet that a lot of the
smaller vendors (especially the cheaper NAS appliances) use samba.

In fairness, samba has done a pretty damn good job implementing a wholly
undocumented protocol, but I’ll admit the days that I’m working with it
are the days I wish I was on a beach somewhere.

I’d like to point out at this juncture that I’ve never tried to filter a
network share, only that I wrestle with samba on a semi-regular basis.

I believe that Microsoft has released some documents rather recently that
describe the interfaces. It was forced by the EC settlement. This should
make it easier for Samba to engineer their design. I hope it solves the
sharing problems and makes it easier. Maybe some of that made it into
version 7 of FreeBSD, but I haven’t looked yet. I would prefer to use
FreeBSD to act as a storage server for some of my files. All I need is the
time to set it up and try it.

Yeah, I’m pretty stoked about the specs being released. Unfortunately
samba can only do so much; if the underlying filesystem doesn’t support
NFSv4 ACLs (which is to say most of the common ones, at least on
Solaris), getting permissions to work in a way that’s familiar to a
Windows admin is a spotty proposition.

And then there’s the issue of uid/gid to sid mapping. If you have this
in your AD/LDAP setup, it’s amazing. It just works, and they’re
automagically consistent across unix servers. Unfortunately, that’s not
a standard feature, and most people don’t want to put it in if they’re
just setting up one server with samba. Which means they’ll be kicking
themselves (and then by extension, me) if they ever put in a second
server and need consistent uid/gids between the two. Of course, you can
put the maps on shared storage, but that only scales so far.

Eric,

Thanks. Yes, I believe it is Samba-based. Does that mean that remote,
Samba-based shares cannot be filtered?

I wouldn’t presume to say anything other than it probably behaves
differently from a remote Windows share in a number of subtle ways that
you’re probably about to discover :wink: I’ve never tried to filter a
remote share, so I have no idea what gotchas you should look for. There
are a number of mailing lists that you can find at www.samba.org. If
you run into specific issues, the one for developers is probably an
acceptable place to ask about it. That said, if it’s an older version
of samba, you might not have much luck there.

Like I said, I just wrestle samba on a semi-regular basis, I don’t code
for it or have ever played with filtering a remote share.

good luck,

~Eric
