 It's just a shame that people who found out about something first got screwed instead of being rewarded for it.

Most of the ones who first found out about bitcoin have been amply rewarded, as have those who figured out the economics of bitcoin asics, either by developing them or staying clear from them.  Not to rub salt in the wound, but I figured this out before BFL even announced its asic, and its the reason I didnt even get in to FPGA mining.

GPU and CPU mining was profitable for such a long time,  because the hardware price had no relation with its bitcoin mining potential whatsoever. Thats why gpu's were dirt cheap for us and gave an ROI in a matter of months.
Asics otoh would be priced purely based on their perceived mining potential, and therefore would never be profitable to anyone else as the one setting their price.

So then you are against what KnC is trying to do?  (Selling ASIC's in general?)

no progress... nmap says need to specify a host...i tried both desktop ip's, but that doesnt seem to give me anything.
there was a 0.0.0.0 ip address in wireshark...?  I tried everry ip address I found...the miner is running, the ethernet lights are pinging away..... huh...  I'm ready to get an ulcer


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.

Perhaps the bridging software you added is waking up with a setup IP address 239.255.255.250 or 224.0.0.2 and you can't access the setup page simply because you don't have a route to that address.

A typical home router, wifi or otherwise, has a single downlink and a single uplink port.  The single downlink port is internal and is assigned the address you designate as the gateway but come configured with the internal downlink (gateway) address as the lowest in the function downlink network.  Attached to this internal single downlink is possibly a 4 port ethernet switch which will appear on the back as four RJ45 ethernet connections; the internal downlink is also attached to a wifi port (if the router has wifi); and lastly the internal downlink port is attached to a DHCP server.  The internal uplink port is attached to an RJ45 ethernet port on the back marked uplink.

A home router has a setup page which has the same address as its gateway.  If you log into your wifi router on 192.168.43.1 and change the gateway address to 192.168.43.13, as soon as you click SAVE on the router setup page, you'll lose connectivity - so don't do that unless you want to hide your gateway.

The DHCP server has addresses it may assign and these are some distance numerically from the gateway.  A linksys router might give DHCP 50 addresses starting from 192.168.43.50 and end at 192.168.43.100.  Your router likely starts its DHCP addresses at 192.168.43.50.  You computer has likely been assigned 192.168.43.51 (judging by your graphic).  The address 192.168.43.50 was likely assigned to a tablet or nook or kindle sometime in the last 24 hours and the router remembered it and didn't assign it to your computer but arp -a doesn't show it because it isn't in use.

So, if the bridging/routing software you added to your computer isn't accessible, you need to put your computer on the same network as it is.

Say the routing software software is showing 239.255.255.250 as its IP address and you can't access it.  Let's try this:  Right click your wireless icon and disable wireless so you can't get to the internet.  Open a dos cmd box and do ipconfig /all and see if the wireless connection is still showing an address.  Release that address with ipconfig /release 192.168.43.51 and run ipconfig /all again and see that it has been released.

Right click your ethernet icon and open network connections.  Go to your Local Area Connection properties and scroll down to Internet Protocol (TCP/IP), highlight and click Properties.  It might have DHCP ticked.  Unclick it and assign this address 239.255.255.249, netmask 255.255.255.0, gateway 239.255.255.001, click OK

Now, in your dos box, command "route print" and see if a route to net 239.255.255.0 exists and trying entering http://239.255.255.001 in your browser address field.  With luck that's the bridging software's setup page.  If not try http://239.255.255.250 in your browser field.

If neither of those work you might try the 224.0.0.0 network address since it's showing 224.0.0.2; assign the ethernet connection an address of 224.0.0.10, gateway 224.0.0.1, and try and access http://224.0.0.1 or http://224.0.0.2 after checking that a route has been added to 224.0.0.0/24

If you get to the bridging software setup page you can configure it with a 192.168.43.x address, then enable wireless, change your ethernet connection back to DHCP, reboot and see what crops up.

This is mostly guess work.

The 239 and 224 network addresses are explained here
http://en.wikipedia.org/wiki/Multicast_address

LAN's see lots of traffic on theese network addresses unrelated to DHCP or regular PC/miner IP traffic.
Windows is very chatty in multicast.

Pheonix,
It looks like your BBB is asking for an address from the pic.

You mentioned a switch.
Some switches filter DHCP by default but can be manipulated to not do this.
ex: Netgear GS108T will fuck with your dope if you are unaware if this.

If a straight cable between the PC and the miner is not working something is odd.
Have you triple checked that the PC (for direct PC/miner cable) is running a DHCP server?
Have you tried another ethernet cable?

You might try physically taking your miner to a different LAN to gain access.
Then you could set the miner to have a static IP address in the web interface.

Subdivide and conquor. eliminate everything possible and go from there.

Just throwing some ideas out there, hope this helps.

orama,

thx for update!

i got one corsair 1050 hx running.

is that also a problem or just the 850???

Mate, cannot say. Not what i've been focusing on to be fair. Gut feeling it's part of the same brand/model family, so I would rather take a swerve. It's supplying to much current from what I understand. Something about a safety in the PSU being triggered and the cap smokes after the PSU is switched back on. They don't have every brand of ATX here to test. Anotherhost popped by with theirs is what I heard, it just so happened that on all those reported it was the same PSU at fault. It's an ongoing investigation, but if you want to play it safe, for sure the Corsair V850 has not shown any problems this end, and is used throughout the hosting currently.

Make my day! Say thanks if you found me helpful Smiley BTC Address --->

@Orama

Just FYI - that's exactly the brand and model of PSU that I use, and my Jupiter has been hashing along very solidly at between 580 and 600 Gh/s since minutes after it arrived - which was over a week ago....



don''t turn it off and on a lot then.. That is what was causing the issue from what he said

That's good to hear, but i'm just relaying what i've been told. It's a popular and solid PSU form a reputable firm, but all the cap issues appear to have this common link.

Given the way that it's hashing, I wouldn't ever have reason to turn it off until it doesn't make back what the electricity costs to run it...

that particular PSU was sending more current so that cap couldn't handle getting hit again without discharging its high load

 Cheesy   once i figured out to use .93 for my miners I don't want to ever touch them again..  avg 1.03 Th right now and .93 is nice to restart cgminer in one of the miners every once in a while if the hashing dips down

Does it affect any Network Protection Statement? No. Any customers that purchased for October are being delivered in October. Any customers after, will get theirs in November, after a month’s gap. No special treatment.

Thanks for the update.  Not trying to come across as racist.  It's just that China reminds me of the Nation 0-1 in the Animatrix.  If there is still a planned limit, then cool.  It is hard to believe that a company would not keep producing for their own bottom line though.  I'll just have to trust you on that one.

Probably better to turn it off with the paper clip than the main switch.
Should be more graceful.

It would be a voltage spike blowing the capacitor.  I had a great old switching supply putting out 16.5VDC from an old heavy laptop.  I had a zTex FPGA board mounted in a small box with fans.   The small box had a voltage regulator on perf board to knock down the voltage from 16.5 to 12v.  I added an off/on switch to the box.  Big mistake.  Flipped it off for some reason.  Now with the off/on switch in place I wasn't unplugging the supply.  The switching supply, floating, was looking at an open with the switch on off.  A voltage built up and I was eventually startled with a BANG, very loud.  A cap had blown.

Could it be the switching supplies are being unplugged while still powered up, allowing a voltage buildup.  Even if unplugged the reattached to power, that buildup of excessive voltage on the disconnected PCIE-4 leads might still be there.  Plug it in a BAM.
