ye from what i can see on bitminter site in "latest shifts" speed is the same like with stratum proxy only one whats bothering me is blade stats page with stratum total speed = 13xxx and 99 efficiency but with bfgminer its 12600-12800 with 96 efficiency ;p
Ah, that you mean. Look into the source code: in driver-getwork.c:handle_getwork() you see how results are processed. The blades sometimes send submit request with empty work field (unclear why this happens), which are counted as HW errors and rejected as 'unknown-work'. Then there are those 'H-not-zero' rejects with a wrong nonce, plus the 'stale' ones. I assume that the stratum-proxy does not reject some of them (e.g. the empty ones) and since the efficiency provided by the blades is the ratio of accepted to requested work items it differs between bfgminer and stratum-proxy (with bfgminer being more accurate). My long term values for efficiency reported by blades is 96.4% and matches the expected numbers quite well.

Must have been added only lately, was enabled by default initially. Anyway, from numerous users I know that the getwork server is working quite well on Linux systems. There are / were some issues with specific OS / libmicrohttpd version combinations, but once solved, the efforts pay off immediately. To serve ~150 clients over stratum-proxy, I had to use a dual-Xeon machine - now a tiny netbook does the job.

i found an error
should be --with-microhttpd instead of --with-libmicrohttpd
now it works
but workers are SGW0 1 etc not like in blade user configuration

Workers are just counted up incrementally based on their username - which is very useful since it allows you to partition your farm arbitrary. In my setup, I have 8 racks of blades operating. I give all blades within a rack the same username, resulting in bfgminer treating them as unit, i.e. I see SGW0-7 and immediately know which rack has problems. In effect, you have a fine-grained statistics chain: each blade reports individual stats; bfgminer reports stats per rack; pool reports global stats. You could even add more intermediate stats layers by connecting bfgminer instances hierarchically, e.g. one main bfgminer serving over getwork server other bfgminers for your sub-domains.

yeah but i have 5 blades and solomining shitcoins for fun. blades goes sick often and then i have to restart them, problem is to keep them in proper numbers i have to turn them on in order it is annoying if instead SGW-0 would be SGW-0-workername (from the auth lan blade) it would be much easier for everybody

I always met a problem of "Segmentation fault (core dumped)" after running for a while, and the terminal closed automaticly. (ubuntu)
Any ideas?

Crashes happen with any miner now and then. You need to run bfgminer from a looping script to prevent your boards from idling. I am using this one: #!/bin/bash
ROOTDIR="$HOME/usr/bin" MINER_BIN="$ROOTDIR/bfgminer" CFG="$ROOTDIR/BEB-bfgminer.conf" STARTLOG="$ROOTDIR/miner_startlog.txt" LOG="$ROOTDIR/miner.log"
miner_run() { MINER="$MINER_BIN --http-port 8332 -Q 50 -c $CFG" echo "Starting '$MINER' at $(date)..." >> $STARTLOG $MINER 2>> $LOG echo "Terminated at $(date)" >> $STARTLOG }
while true; do miner_run sleep 5 done
exit 0
Save this as $HOME/usr/bin/BEB-bfgminer.sh and adapt the related variables for your configuration. Run this script with screen and you have the perfect control over it for local and remote access. To have it started during boot-up, add this line to your /etc/rc.local: sudo -u <your_username> screen -dmS "BEB-bfgminer" /home/<your_username>/usr/bin/BEB-bfgminer.sh
To attach to the miner's screen session, run to detach from the screen session press <Control-a><d>. If you happened to forget detaching and want to attach from a different terminal / location, you can force detaching the previous session and take over with Finally, you can follow the log from local or remote sessions with tail -f $HOME/usr/bin/miner.log
Happy mining

Crashes aren't a given, but I'd need at least a backtrace to try to debug it :/

Right, fighting the symptoms is always the second best choice. Problem is, I never found a crash report or core dump while running bfgminer on my Ubuntu system, but from the startlog I know it restarts every now and then (in the order of once per week). Since this happens without interaction, I conclude those must be crashes - which might not be correct.
