Can you give the full route table the pineapple has.
Can you also give the ip's your interfaces have.

Thinking of power supplies again. Check out this puppy. From just one of those I can power 2 Odroids off of 12v at 93+ % efficiency (expected power draw of an Odroid in full swing with idle gpu is 1.5-1.6A)! It's 2cm high, but so is the odroid so I'l still happy.
Only drawback is I'm going to need a voltmeter because the output voltage is set by turning that little screw on the blue brick and there isn't exactly a 'setting' for 5v. Then again, I'm pretty sure I'll find a way to make good use of that aswell plus I found one for under 10 euros on deal extreme again (they're true to their name, I'll give 'em that).
You do mean 93% of a 83% power supply. getting you near 80% or something in total ;) About the voltage. You have a litle room, But your best getting as close as possible to that point :)
Btw where are you ordering those odroids ? Any dealers in the eu ?

First of all a bridge needs 2 interfaces, What this means is that data will freely flow between them:
ifconfig at0 up
br-ctl addif br-lan at0
br-ctl addif br-lan wlan0 ( if you want to bridge towards wifi of the pineapple, use eth0 for ethernet cable )

ESXi version is completly free. it got some minor things you need to do manualy. Like taking backups and such.
Also they limit the memory to 32GB per cpu. But for small businesses and own use its perfect :)
for small clients we use i7 with a decent mobo. ( also if you need usb pass-through your cpu needs a special visualization option )
You could also go for something like this:
If you really want it to be fast trow in a SSD for storage.
For AD learning. maybe you can start of with a old server 2003 license ( they still got 2015 support, DONT TAKE SBS )
other option are buying a real cheap ass server or 2nd hand server that supports ESXi
You could run like a network share server on this. But media server isn't really a option. ( esxi doesn't give a screen output ) So your better off using something like a pi or odroid or ... for media server and maybe use the esxi as a storage. Or if your tv supports DLNA you could try that.

That would be helpful. thx

Performance on one node (4 cores):
Odroid: 3.79 GFLOPS
Performance on the whole cluster:
Odroid (6 nodes, 24 cores) : 16.13 GFLOPS.As I suspected ...
Running flat-out processing tasks individually, 6 ODROID x 3.79 GFLOPS = 22.74GFLOPS
Running 6 nodes: Odroid reaches 16.13 GFLOPS
Nodes lose (22.74 - 16.13) 6.61GFLOPS vs individual ODROIDS running flat-out.
... in fact a lot worse that I thought. Nearly 2 ODROIDS-worth of effort lost.
So from a test that ran last year you can see the results if you would cluster the odroids. It has a big drop in performance compared to
running them standalone. But this was on a test with high traffic if i remember. so maybe its less on pure computing setup
-
As far as look into making computer nodes / clustering. The penalty is to big on the odroid.
Towards the gigabit. Why get a gigabit switch when the odroid got only 100Mbit connections. Ok the processor has a higher switching pass-through. But will you have so much data traffic ? that's the main question
As for the switches. Because of my job i can the zyxel without any problem. the tp-link is a good alternative.

Hey guys,
Cloudflare has made a challenge!!!
So you can legaly try and steal the sll key from there challenge server.
More info:
-
Yeah. also possible.
I myself am looking for a small BOINC group/cluster. Maybe running 1 of them as GW. And using networkboot to load the others. For switches ill probaly gone use zyxel ES-108A ( dont need 1gbit on them )They run of 5V 0.6A

Just a small youtube clip about the win xp background.

Hey cooper. Found a interesting power supply you might can use.
http://www.circuitspecialists.eu/power-supplies/switching-power-supplies-encl?output=27
if you get a switch on 5V. You could run it all of that

You mean like the VM server Darren made? out of 2 ikea picture frames. The one that hanged in season 9 on the background wall =D
It was/is a nice piece of working art :)

The first ikea mod i have seen. Was a full desktop build into a 5cm thick ikea shelf.

yes you can do that. But they check how many times the dns names gets a lookup. and it thats to low, you get a mail to see if you still want it active. If you don't click the link keep active the dns will be removed the next month it checks.
So its a pretty good system but not if you only use the dns a few times a year.
-
No-ip is optional. But you need to use it regularly or it expires.
-
if i can remember correctly. the bnc connectors aren't great on the higher freq ( >1Ghz ) like wifi ( 2.5 or 5 Ghz ). So go for the sma connector
-
Hmmm think ill need to look a litle deeper in the Odroid.
-
yeah, you may forget mining on this.
You seen the new rasp pi ? its like a plugin pci. Redesign a new base board to plugin like 16 of these and you got your superpi :)
-
Most of the time tracking stops at the airport in the USA where it leaves for the country of destination. its probably already at customs in UK. Mostly it takes a while at costums
-
yeah the delivery got kinda delayed. because its pretty new. ( kickstart project ) But they always been given decent information. And why things are delayed. atm there clearing a 15 000 device backlog. I ordered 1 in november to mess around with. At least they gave every1 the choice for a free t-shirt or a case.
-
Ever looked at: http://www.parallella.org/ they got 16 cores at 700Mhz. you also got version with 64 cores. And there made for clustering.
The disadvantage is: You need to compile it on the SDK of that board. and some restrictions in the hardware.
-
Think there enough old timers arround that maybe got the epp.
-
1st. An array is always a 2^n elements. ( 1,2,4,8,16,32,.... )
2nd they should point in the same direction. Otherwise you dont get a amplification of the signal.
Some basic info: http://en.wikipedia.org/wiki/Antenna_array_%28electromagnetic%29
Now if you want to extend your range in all directions. You need to build a antenna like Darren & Shanon did.
-
Like Wifi-stuff said. To have all the need stuff use tap ( layer 2 ).
It's also better if do the setup yourself. That way at least you learn how it works, and it something goes wrong later you know what the problem could be. All the info you need, you can find in the 3 guides posted on this thread:
http://openvpn.net/index.php/open-source/documentation/miscellaneous/76-ethernet-bridging.html

No srry was wrong. i thought i used a mixed somewhere but its a dual tap setup.
There's always room for Pi.

Yeah taught so. There hell of expensive for EU
