Nmap worked for me when I specified the gateway, properly the lowest address in the subnet, e.g. 192.168.1.1.  So, I don't have the graphic in the reply box but wouldn't you use:

nmap -sP 192.168.43.1/24

Try ipconfig /all and you'll probably see the .1 is  your gateway, the .51 is assigned to the machine you're using.  .255 should be the broadcast address of the subnet.  As I understand bridging, if done properly, the computers after the bridge should have addresses in the same subnet as the .1, .51 and .555.  So, the bridge isn't setup correctly I think.

Yep, works just as well on RPi.  Interestingly both a debian machine and an RPi, both using nmap -sP 192.168.1.001. showed an unknown address in the DHCP range but not assigned by the DHCP server.  Google shows it has something to do with Windows and that the address is likely assigned to a device in the Windows machine itself.  (Hon Hai Precision Ind.Co.) manufactures the interface and Foxconn manufactured the mb.

Nmap worked!  Showed the Blade as well.  It wasn't installed by default on my linux machines but worked immediately after installation.  I tried installing it on a RPi but failed as sources needed updating.  Ran update and am installing nmap now.  Probably should have gone with download source package so as to preempt all these additional packages that are time consuming and with limited space on the SD card.....

(added a bit)

If I understand bridging correctly you should be on the same network as the wifi and the wifi router will be able to tell you what dynamic IP addresses have been assigned.  Plug those into a browser address field one at a time.

Not all that many years ago a photo of a Bejing main street showed a couple or three vehicles, little more.

Trying arp -a from a Windows cmd box give me three addresses on my network while on a linux machine the same command comes up with 7 addresses.  The three from the XP cmd box are two Raspberry Pi and the router gateway.  A Blade address as well as three machines running linux and samba aren't reported by Windows arp -a.  So, the question is, will a Jupiter respond to a Windows arp -a from as the the pair of Raspberry Pi (one running minepeon and the other stratum-mining-proxy) do or as the Blade does?  The Blade isn't showing up arp -a on a Debian linux nor with arp -a in an XP cmd box.

A ground loop problem is unlikely but the power supply has internal grounds then there are multiple connections to the miner, and all those miner power connection grounds are likely common, so a ground loop allowing an oscillation isn't impossible.

I think what he was saying is that pool users configure their own mining scheme and using the pool, the pool gets a percentage and that percentage to the pool is what is being used for the delay refunds.  I suppose they would like to configure the miners for the users the best way possible as that would mean a larger amount as that fixed percentage - success of those in the pool is good for them.  But, given the type of people we miners are, we'd probably complain if we couldn't make our own choices even if not optimal.

So, since you were in the 1-500 group, then KnC adjusted for refunds and non-payments which put your orders in the greater than 1000 range, one might assume they added 1000 to the order numbers, and now no order number is less than 1000?  

If they did ship 1400 orders in 7 days, they match BFL's predicted output rate of 200(units)/day.

So, initial order numbers in the 1-500 group, after realignment for orders that were canceled or went unpaid, fell into 1000-1500 range?  How is that?

I feel the 14xx shipment date is good news!  July orders start in the 3000 range I think.  Production rates have likely stabilized at a higher rate this week than last so we can probably expect more than an additional 1500 orders filled by this time next week, possibly more since Merc's will be faster to build.

From windows putty to cgminer in minepeon reduces in size and still has a readable screen but putty to a raspberry pi running stratum-mining-proxy wraps the lines in a way that's not very readable tho one could keep that screen full width and reduce the height.

So, worthwhile getting a beaglebone with which to practice?  Is the linux networking less like debian and more like something else, say Suse?  We know Raspberry Pi is Debian Wheezy.  What's this linux?

Ah, the British Isles.  Lots of rain, fog, clouds, and at that time likely, mostly incandescent bulbs.  Resistive loads will use less power with lower voltage but motors get more efficient with higher voltages.  You would have been turning on lamps earlier than in brighter climes.  A few short years ago what was then the largest natural gas electric generating facility in the world came online not far from here.  It provides power for a lot of the southeast, Florida, Georgia, South Carolina, Tenn., Alabama.  Before it went online I could measure voltage at the wall to be between 126 & 128VAC.  Surprised me as it was lower on Long Island where I'm from.  Lots of rural homes out here, long lines.  The the new electric facility had a different policy.  Voltage at the wall went bam smack on 120VAC, maybe up to 122 VAC at times.  Overall there had been a trickle up effect, the northern states getting some free power.  That stopped.  They hustled adjusting voltages mid-summer.  Suddenly power lines were falling all over the northeast, particularly Pennsylvania.  Up north there they must have seen it was going to be reflected in profits and had no reasonable way to explain it.  They must have started lowering their own voltages relative to one another.  Lines got hot, stretched, broke and fell.  Things that use to work well started drawing more current.  Global warming, lots more AC use in the south, think they'd lower their voltages if the AC were going to be costing the customers less?  Don't know for sure, this is just my theory.

Perhaps the UK power utility saw what a large fraction of electric usage they had of incandescent lamps and with the low power bulbs coming on the market decided to fudge profits by making electric motors less efficient.

Really?  Running air conditioning or the refrigerator at 120VAC is more energy efficient than running at 126VAC?  I suspect not.

And both the USB and 5 volt power ports have been removed from the beagleboard?

And there's the best reason to use the dry hands paper towels for opening the men's room exit door.

I've a July Merc order #31xx and wonder if that number is fixed or has some relationship that changed the first 500 Jupiter/Saturn pre-order sequence effected it as well.
