I have tried a few pools and wemineltc gives 12% rejects but ghash.io only gives abort 5%.
Cant get it to work on Ghash-io , it starts mining then hash rate goes to from 250k to nothing in about 15 minutes.

I have a detailed post on litecoin talk

Interesting stuff I found this snippet of code in the miner that is curoious ? seems like a specific flag for ghash-io

Code:
 if not self.isRunning:
            if ('ghash.io' in stratum_host):
                self.proxy = subprocess.Popen(['/usr/bin/python', 'stratum-mining-proxy/mining_proxy.py', \
                                                '-o', stratum_host, '-p', stratum_port, '-gp', getwork_port , \
                                                '-cu', username, '-cp', password, '-pa', 'scrypt', \
                                                '-nm', '-q'], stdout=subprocess.PIPE, shell=False)
            else:
                self.proxy = subprocess.Popen(['/usr/bin/python', 'stratum-mining-proxy/mining_proxy.py', \
                                                '-o', stratum_host, '-p', stratum_port, '-gp', getwork_port , \
                                                '-cu', username, '-cp', password, '-pa', 'scrypt', \
                                                '-nm', '-cd', '-q'], stdout=subprocess.PIPE, shell=False)
            self.isRunning = True


I checked the default stratum proxy code and there is no flag -cd in the default code, and it seems to be removed if you are using ghash.io which the Alcheminer recommends kind of strange to me

anyone know of a remote debugging tool I could use to step through the code as the miner runs and look at current variable values ?  The os is debian/Linux

Running an Alchemist 256 box right now the unit is very loud but very well built.

Has software issues though , i think it needs some work on the miner code to improve effiency and pool performance.

Seeing a 20-30% reject rate and alot of failed getworks  on Vardiff pools

MAT has gone bankrupt so there will be no new support from them. I managed to get it working. Will update to Alcheminer this week. This miner uses ubuntu and the only files it changes are located in the admin home folder. So there is no chance of a brick. It is still linux so it should be easy to do it manually. Will post my findings here.

Also the only open port on my miner is ssh (22). And i dont have the login. Anybody have that? or how do i factory reset it?
You sure you want go go down that road? The gain is minimal and the powerdrain gets up.
And there can go things wrong, if so MAT can`t help you anymore.
