[FIXED] My both Antminers stopped working !!!

[rammy2k2]

It was ghash.io fault .. phew ... i got scared

Double Check your network configuration on the WAN. I had two working when I had the broadcast address in there as 192.168.1.255 and the DNS as 192.168.254.

I had two  randomly shutdown. They would turn on and allow me to browse the web interface but would not start hashing.

I had to remove my broadcast address of 192.168.1.255 and replace my switch my DNS address from 192.168.1.254 to 8.8.8.8

After that check your Power supplies but since two are failing I think It is your network configuration.

i can connect to them too, but they dont start mining  

i already have them to 8.8.8.8, sushi set them up

Cheap or underpowered PSU perhaps?

[rammy2k2]

no, 1000W PSU, and not cheap, they runned just fine for about 1 week. ill power up just one, to see whats up

[rammy2k2]

same stuff with only 1 miner .. i can connect to it ... no mining

[r7970]

What brand and model power supply are you using?

[elasticband]

can offer you some Team viewer help

were you wired or wirless connection?

the fact you can still connect to them is positive

[rammy2k2]

ok, things are fixed, looks like it as only ghahs.io fault ... their NL server is dead , thanks everyboy for the help !!!

You didn't setup backup pool?
You will loose btc once in a while if you don't have a backup pool.
All pools like to DDOS each other, we are talking about big money.

yea, i didnt, words of the day "BACKUP POOLS"

Ghash.io decided to change the stratum addresses (or more specifically, turn off nl1.ghash.io:3334) overnight. I woke up to angrily beeping antminers as well and it took me a few minutes of antminer rebooti, router reboot, modem reboot, and then looking at the ghash.io frontpage.

for such a massive pool, they have some of the most terrible client support you can imagine. This is not the first time they have [seemingly] arbitrarily changed the ports or addresses to connect stratum users, not to mention at least 30minutes-1hour of downtime every day

<soap-box>
GHash.io has surpassed 30% network hash rate. I might recommend people move to other pools. I've stopped mining at ghash and have returned to btcg FWIW.

you realise that you left the 30% network hashrate pool for the 25% network hashrate pool? It would be much better to move hashrate to pools like slush's or elegius or p2pool

thats what happened to me, i freaked out with those beeps

 Slush doesn't have the "bells and whistles" I enjoy, have ideological issues with Luke-Jr/Eligius that prevents me from mining there, and P2Pool is not optimal for ASICs IIRC :|

 Tried Bitminter for a couple months, but did not provide me the stats/graphs that I enjoy dorking out over.  

 BTCG has always been solid for me and I appreciate how active Eleuthria is in the community.

too high fees for me ...

LOL. You think P2Pool has 150 TH/s of ... GPUs?

P2Pool works absolutely fantastically on most asics.  My avlons are at about 115% PPS on P2pool (both from reviving fees and because p2pool appears to do better than expected, potentially because of the faster block relaying giving it an advantage over other pools).

Sadly, the little CPUs on the antminers combined with their old cgminer version is absolutely taxed beyond belief, and they don't work fantastically on P2Pool right now— stale rate roughly 5x the avalons. I've been nagging them to post their firmware sources since they started shipping products so I could fix it and I guess they've been too busy.

They apparently bumped the version of cgminer in their latest firmware.  I haven't tried with p2pool yet though.

 I said nothing about GPU's. I was referring to anecdotes I have heard that mining with ASIC's on P2Pool was not optimal vs other pools.

 Thanks for the LOL. Helpful and classy.
