You can run Apache on your gateway and get it to proxy stuff into your internal network.

It's all running off a 1GHz C3 Mini-ITX board in one of these! I didn't pay that price for it, they are really nice people, I went to see them and they did me a really good deal. I also splashed out and got 2 new 250Gb WD RE from Scan. I am so happy with the format, I think I am going to shift the CCTV server into one too

Is that a BT patchbay I see there?

Definitely custom. MDF?

It's sort of custom, I got it from a company called Wizzard, they make rackmounts to go in music and TV studios, but they seem to have gone bust as their website is down? It's a beech veneer finish, so a little over the top for my needs, I think I would make the next one myself out of MDF.

One problem I do have is cooling the room, it doesn't get very hot, but hot enough, it's a sealed room and can get upto 32 if I leave the door shut for a week or two, does anyone have any ideas about cooling a sealed room like this without noisy fans etc... Unfortunatly as it's under the stairs and in the middle of the house there is no access to an outside wall. I was thinking of some kind of temp sensor that could control a small fan, and report to a webpage of course! Something a little like the WeatherDuck?

Or, am I going a little over the top for a home setup

Cheers

Cris.

What I want is a solution that will allow me to monitor the temps on a webpage, and automatically activate some form of cooling system when needed, without me having to go open the door for a bit

N.B. anyone who is any good at Unix shell scripts, sed and the like, cover your eyes now.

It was pretty hard to read with my eyes covered , but...

How about replacing the two first scripts with this:

Code:

---

sed -n -e '3s/^....\(..\)\.\(..\)/\1\2\n0\n0\n0/p'

---

Given your input data, it produces:
Code:

---

1268
0
0
0

---

        DS Line Attenuation:    40      DS Margin:              8

cut -d: -f3 | sed -e "s/ *//"

So my shell script uses "head" to grab the first three lines of the output of the serial port. It then uses "tail" to grab the last line of the three.

Hmmm, the \n doesn't give me a newline, it just outputs "n". Perhaps it is because I have a very old copy of sed (this box is still on RedHat 7.1).

I just see so much stuff being done with SQL databases, PHP, and Perl, when it could all have been so much simpler as basic ASCII flat files with an awk script or two.

If however I use the power switch on the box to power it off and back on or yank the power it refuses to boot. It powers the main board (the Ethernet link light comes on) but doesn't turn on the VGA output or spin up the drives.

I usually just make sure that resume on AC is selected in the BIOS and usually takes care of it.

I have that set, it doesn't help. When it is in its "hot" state you hit the power button, the power light comes on but it doesn't event attempt to boot.

Hey, I just cracked 3000 posts

Thanks to your post I finally spurred myself into action and bought the parts for my silent server (to replace the two big noisy and hot servers that currently live in my garage).

I was going to buy my T2e chassis from mini-itx.com, which would have cost me £150. After your post I bought it direct from Tranquil for £65 (via a "best offer" bid) ! Thanks.

I also got a PSU and EPIA SP13000 from them at the same time, with only £10 postage for the lot.
