But when reboot it will DHCP again - only when "sudo wicd-curses" & re-connect will get the static IP address. Any idea how to solve it?

Potential power issues?  What kind of power do you have going into your powered USB hub? Which USB Hub are you using, it could be getting backfeed upstream into the Pi too depending which hub you have and triggered by the LS.  Assuming you don't see the same behavior when it's just the 2 jalapenos right?

Directly is even worse... try a different powered hub.

Check out this site for the best hubs to use with Pi's: http://elinux.org/RPi_Powered_USB_Hubs
You should also lookup your existing hub on that page and see if it is known to have issues with backfeeding power upstream or delivering enough power.

How to update to recent version or CGMiner, please?

I did:

wget http://ck.kolivas.org/apps/cgminer/cgminer-3.8.3.tar.bz2

tar xvf cgminer-3.8.3.tar.bz2

cd cgminer-3.8.3

./configure --enable-bflsc

make

sudo make install

But still I see: cgminer3.6.4 in the minepeon web GUI.

After you compile the install, you would need to move the executable file (cgminer) to the proper location.

Assuming you did this all from the home directory you would want to do something like:

Granted the way you compiled it, it will only have the drivers for BFL devices, so don't be surprised if nothing else works

How many pools do you recommend to use?

Do you prefer or recommend CGMiner or BFGMiner?

I like to keep 3 pools in my config but I would recommend at lest two.


I recommend both!  What you use is up to your personal preference though.

ok thanks I was hoping I had missed something.

For about 2 weeks I was mining happily, then all stopped.
My pi was saying all 3 BFL were sick or would just spew out a load of crap like unaccepted... (I can't remember what it said)

I thought it might have been my USB hub, but I've just changed it over to a new verified one and it sill not working right, it lasts about a minute before it says they are sick again.
And that's if it detects them, must try's I had to ssh and do a auto detect in BFGminer.

I have a 5GH/s Jala, 7GH/s Jala and a 30GH/s LS. And a new BELKIN F5U234CW Hi-Speed USB 2.0 4-Port Hub.

What I did notice before I disconnected the above was the lights on the Hub would go out, the one's connected to the miners??
I still think it's a power problem, but the pi is plugged into the mains. (with adapter :-))


EDIT1:  I just plugged my miners into a old PC running Win7 32bit and they all work!!!
