Most of those one-stop solutions will steal any bits you get. Even the so-called "front ends" for BFGMiner and CGMiner are bogus. Learn to use BFG Miner.
Gladly learn if I could find a f00lproof howto on getting this thingy to work.... Any pointers/examples available? Goal is to mine verge (XVG) coins...

I used BFGMiner to mine Bitcoin. Sorry, but I can't help with other coins. You are going to have to search the forums for specifics on XVG.

Is BFGMiner 5.4.2 available for Ubuntu 16.04 users?
I have a new install of Ubuntu 16.04.
Bitcoin Core 15.1
BFGMiner 5.2.0
I am trying to upgrade to 5.4.2 to see if will resolve an issue and when I use the command
apt-get install bfgminer
it says I am already at the latest version 5.2.0. I installed it only a week ago.
How do I get upgraded to 5.4.2 if it is available for Ubuntu?

Confession: I am a newly convert to Linux so go easy on me.

more instrutions for the clueless would be nice I had a problem with bfgminer-5.4.2-win64 with it marking 2 of my Eruptors as Dead this morning I came to the conclution that the Serial Driver might be the cause So I installed https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers Win64 driver for Win10 I have version 1709 is this the problem Is my version too old??? I reloaded the Win10 Genaric and it works now but I still get a COM5 Error not enough Admin privlages which is BS I own the hardware.I niticed they are all set to 9600BAUD is this another error communication speed should be much higher right I did try setting it as high as my 3D printer communication rates this is when the driver crashed and I had to reinstill.... so Do you leve this com rate at 9600Baud???

I am solo mining with Ubuntu 16, Bitcoin Core 15, BFGminer 5.4.2-29, Antminer S3.
BFGminer is requesting a new block be created by the Bitcoin core every minute like clockwork.
Is this expected behavior?
This seems to be excess work being placed on the core for no reason.
Is there a startup flag for BFGminer to control this?

It seems the sequence of events should be...
- A completed block arrives in the Bitcoin core from one of the peers.
- Bitcoin Core notifies BFGminer of this blocks arrival.
- BFGminer sends a request to the core to create a new block from the available transaction in the Mem pool. “CreateNewBlock”
- Bitcoin core passes the new block to BFGminer, who then distributes the header out to the miners.

It seems that a “CreateNewBlock” would only occur when it is needed after a completed block has arrived. Can anyone shed some light on this process? Thanks.

The below log shows a new block being created every minute on the 35 second mark with the fees increasing, until the completed block 502417 arrives in the Core from a peer node at 20:10:12.
A new block is then created that very same second and I assume passed to BFGminer, with a much lower fee than the one created 37 seconds prior.
It seems that all the prior blocks being created, just in case they are needed, are trumped by this new block created just after a completed block arrives.
Why is it such a lower fee? I suspect because when the completed block arrived, the Bitcoin Core removed all the transactions used in that completed block from the Mem pool of available transactions. Pretty much making all prior blocks created for BFGminer invalid as some of those transactions may have been in this newly completed block.

It seems to me that you shouldn’t create a new block until after the current completed block has arrived and the Mem pool has been updated with available transactions.

Not sure this is the correct way to ask, but

any chance of getting support for Innosilicon devices with BFGMiner ?!

As I understand it, the current scrypt maintainer has  his own mining hardware, so probably isn't interested in supporting competitors.
So you'd need to find someone willing to write and maintain a new driver for it, and probably Innosilicon would need to provide at least specs of some sort (and ideally sample hardware).

nwoolls (who used to maintain BFGMiner's scrypt drivers) has been MIA for a year or so, but maybe if you PM him on the  forum, he might get an email and be interested?

Does the stratum-proxy only work solo against a wallet, or does it act as a pass-through?

If pass-through, can it be run multi-port? Would the command look something like this?

Code:
./bfgminer\
 --stratum-port <port> -o stratum+tcp://muppetminging.fakeurl -u fozzy.bear -p wukka_wukka\
 --stratum-port <port> -o stratum+tcp://happydaystv.fakeurl -u <arthur.fonzarelli> -p he-ey

It can do both, but the stratum pool must provide at least 3 bytes of extranonce2.

Does it help if you have the open source of the innosillicon's version of cgminer with the driver ?!

Yes, possibly that is enough, but still someone needs to port it to BFGMiner.

Hi,
I'm trying to mine some litecoins with bfgminer. I've downloaded and installed the software, modified my bat file to look like this for my GPU card:

bfgminer.exe --scrypt opencl:auto -o stratum+tcp://us.litecoinpool.org:3333 -u <<userID>> -p <<pw>>

However, as soon as I execute this (double-click on it) - it opens up the window to start running it which is great.. bad news is that it's pointing to a slushpool.org site and the userID is also wrong instead of my site? I don't get that? any help here on that? It's version 5.4.2

oh- also, I wasn't sure if the .conf file needed to be modified, but I opened it up with notepad and found that it also had that slushpool on there so I changed it to my pool information, and it's still reverting to the slushpool information.
Was I supposed to save the config file as a specific named one? If so, then what should it be named?


Thanks

I have Windows 10 x64 (4gb ram)
old bfgminer 5.4.2 worked x32 and worked x64
but new bfgminer 5.5.0 - work only x32 version. If run x64 version, then after 10 second program close and generally nothing written in the console!

Hi,


I'm trying to solo mine on 2 Bitmain S9's, using BFGMiner.

Do we have to compile BFGMiner, or can we just use the exe provided ?

S9 isn't supported yet. Ask them to send me docs & sample.

In the meantime, you could run BFGMiner as a stratum proxy on another PC.
