I wish it was a dns issue..but from reading other threads for asicminer tube
https://bitcointalk.org/index.php?topic=735728.200 ..its looks more
like buggy software connecting to the pools and errors out and it won't hash.
With some testing these are some of the pools that worked for me which might be useful for other newbies like me.
btcguild
stratum-lb-usa48.btcguild.com or 50.31.189.48
Bitcoin Affiliate Network
mining.bitcoinaffiliatenetwork.com , east1.bitcoindigger.com , west1.bitcoindigger.com
ghash
according to this thread
https://bitcointalk.org/index.php?topic=768500.0 by WBF1 and the asicminer tube owners
this other pool works
mmpool, slush pool
Pools that worked with bfgminer proxy with this setting
bfgminer.exe --stratum-port 3334 -o pool url:3334 -u userid -p password --set-device PXY:diff=512
eligius,bitsolo,f2pool but unfortunately not too stable...bfgminer would error out from 1-3 hrs and the miner looks like its connected but it wont hash.
Pools/leasing service that I can't connect to
p2pool,westhash/nicehash,miningrigrental,betarigs
Anyway we can connect this to a rasp pi like btcgarden amv1x2? Looking for alternatives here...
