Stand-up Firewall Mark-II

Or version 2.0 as you prefer.
I was not very happy with the outcome of my first project so I decided to improve it slightly.
I got rid of the nails and started drilling small holes in the wood in order to use now screws so the motherboard could fit better to the wood.
I also got rid of the plastic handcuffs :-P and now I am using some clever solutions to make the ethernet cards more stable. A dumb adapter cover with foam glued to the inner side holds them together and it is attached to the mobo with a plastic strip (the mobo had a hole just in the middle :-) )
Additionally I am using a small "fonera" as wifi access point attached to the firewall using a molex for power and its standard RJ45 for data (attached to my last free 3COM adapter).
So now those are the final specs (until my next generation firewall appears of course :-D ):

• M0n0wall firewall OS v1.3x. 
• Boots & runs from Compact Flash to avoid power hungry disks.
• 5 fast ethernet ports (100Mbps), 1x integrated + 4x 3COM cards.
• "Almost static" WAN IP thanks to DynDNS
• Variable speed fan with manual control to avoid noise.
• Wifi 802.11g using a fonera with extended range antenna.
• Fonera using Gargoyle  firmware v 1.4.7. stable branch.
• Motherboard donated by a DELL (cannot remember model but ... who cares?) Optiplex GX150.
• Intel Celeron 900Mhz Socket 370 with the lowest TDP. Just 27 Watts.
• With QoS and full use of Bittorrent it only goes up to 75% of capacity so it is good enough (for the time being since it has just a 45 Mbps/2Mbps internet connection)
• 60 W PSU donated from an old SUN machine.
• Shelve from Leroy-Merlin.
• Lots of fun :-D

Gamla eller Nya

After the stand-up firewall, my first project, I had to come up with something to make good use for the rest of the spare parts I had scattered all around.

So I decided to go for a NAS project, and here is the outcome:

• OpenMediaVault Debian based NAS OS
• OS boots from Class 10 SD card in a USB 2.0 port
• Industrial mobo with mini-itx form factor
• Intel T7300 Core 2 Duo CPU
• 3 Gigabit ethernet ports
• 4 SATA ports with 4 SATA disks in RAID 5 (8GB raw capacity so 6GB real capacity)
• Two compact disk cases to hold the 4 disks together and reduce vibrations.
• Mini PSU capable of 450 400Watts but using just 35W in iddle mode.
• 3 different fans with their own speed control to allow reduced noise
• 1GB DDR2 SODIMM RAM in two modules.
• Shelve from IKEA
• Shelve from Leroy -Merlin
• 4 rubber legs to avoid vibration
• Some screws and loctite eveywhere along with black paint to cover some scratches :-P
• Massive fun :-D

Of course it has some more bits but I cannnot recall them all just now.

Presenting my shiny new stand-up firewall.

Being freaky has things like this.

Due to some unused shelves & some spare parts I had at home I managed to create this "thing". Actually it is my new firewall.
Since the last one was unable to cope with my ISP's bandwith I decided I needed a new one. So I did it.

Good air flow, no noise at all and 0 capex :-D.

Thanks to Leroy Merlin and M0n0wall :-P

PS: It is still in prototype phase so expect some cosmetic changes during the next few days.

Winter morning in Almería

As seen from "Sweet Water Hills"

January day (Winter in South Spain)

This is how it looks a winter day in South Spain (almost 18ºC). Several "cañas" & "tapas" had to be tasted :-P

A November night in Dublin. Good beer as usual. Good pubs also.

Up in the air (again)

I start sharing the football player feeling. I am in a lot of places and I know no one... Rather sad isn't it?

The Eye of Sauron

Madrid as seen when you return from a trip abroad. Even looks good doesn't it? Don't get fooled, it is just a demo ;-)

Mainz night

Mainz, Germany.
God place to run one enablement.
Nice pork food und beer.

Barcelona as seen from Hilton hotel

It looks like a futuristic place, and may be it is.
Two interesting days spent working in Barcelona, a pitty I could not enjoy it more.
At least I could see the "Sagrada familia" from the taxi on my way to the airport...
