Replaced a wired router after it had gone flaky. The new one has some
kind of built-in TDR cable diagnostics. From my remote access point in
my office I can see that three of the four ports are connected
properly and there is an open at 7/8 meters on the Tx/Rx pair
respectively. There's an unterminated 25' cable plugged into that
port. Not too shabby for about $35 US with rebate.

Also they've upgraded the processor to an ARM9 from ARM7.

We have a gadget here that's a network file server, about as big as a
pack of cards. Has one Ethernet port and two USB ports for hard
drives.

Soon you'll be able to buy a network file server, with a hard drive
inside, for something like $80. Somebody has a single-chip
Ethernet/IDE bridge chip.

Die, Windows Server, Die!

When I bought the SMC Barricade for the office they also had a version
with a hard drive for exactly that purpose. It wasn't much more
expensive than the plain vanilla router IIRC. This vanilla version even
contains a little print server in case a printer doesn't have a LAN
port. I didn't know that and when it arrived I wondered what that
parallel port in the back was doing there.

Mine doesn't have TDR :-(

But, when a cable is suspicious I can always resonate it out.

I have the SMC Barricade as well. Love it! And the print server.

If that is the Linksys, there are even patched OS's for it, to do other

things with the ports!. It is basically a 'micro' cut down Linux server.
Impressive for the price.

It is the sturdiest piece of equipment in the office. Except for the
stuff I built myself, of course < boast mode off >.

Maybe I should have gotten the one with a built-in HD. The backup HD you
can buy at the stores are nowadays all USB and that just isn't practical
in a network.

This one is apparently not Linux-based, rather ThreadX OS based. It's
got 1M of Flash and 8M of SDRAM as well as the 133MHz ARM9. All on a
cheap 2-layer PCB a few inches square:

Compared to the previous version they've shaved a crystal off and
replaced two linear regulators with a switching regulator. They also
replaced the dim light pipe LED assembly with the right-angle mounted
LEDs. The thing runs off a tiny wall-plug 5.0V 2A switching supply
(but I measured only about 500mA @5V consumption). 10W would make that
little box pretty hot.

Awhile back I bought a bunch of those "BAFO" boxes that hold a drive
and provide a USB interface.

Old drives go into a box and go on the shelf.

Today, as a matter of fact, I drug out a 5-year-old drive to look up
an old project.

I have seen those but it's been a while. But they still can't be plugged
into a LAN jack and be accessed from all the other PCs.

I have my biz stuff backed up since day one and stored off site. Heck,
there are even some documents that were written on IBM EasyWriter
(remember that one?). Ok, now everybody knows that I am not a kid anymore.

And what file system does it use ?

I've seem something along those lines but with internal IDE drives that
provides simple network storage but it only currently supports XP IIRC.

And no I can't remember offhand who does it now ( it was one of the usual
suspects though ) but the XP only thing put me off pursuing the matter.

That would not be a true network storage system. A real system needs to
accept files from any source that can talk to the LAN. Otherwise you
could forget sending output data of lab gear to it.

That would put me off as well. No MS-centric stuff in this location.

One day you might understand the commercial benifits of using
microsoft.
