Linux mining distro for the Raspberry PI - MinePeon

[Morblias]

check /var/log/ see if there are lots of log files you can delete (few people need to look at them)

Edit: ls -orS /var/log/
The largest files will be at the bottom - if they end with a number - delete them.

Edit2: du -sch /var/cache/apt/*
Also another place to look for stuff that can be deleted (with the appropriate command)

Awesome! That worked. Apparently my auth logs were huge. Also I have a btmp.1 log file that is extremely huge. Any idea, is that from ssh guard keeping track of failed login attempts?

I just googled it coz I've no specific idea what normally goes in btmp (and I think it varies from one linux to the next)
I did a failed login and it didn't effect it.
Not sure - hopefully someone else will know.
If you are still short on space, just delete btmp.1, if not, wait until someone else posts details of what's in there
(my btmp is 0 bytes so I can't tell looking in btmp)

Hmmmm, it is probably your ssh guard that is building up lor log files.  I will get logrotate to keep a better eye on it (and btmp) so we can avoid problems.

Your logs must have really been HUGE by the way    .

Just installed to an unused 256Mb pi and its sitting there cpu mining whilst I await delivery of some Enterpoint FPGA's

I stuck a script in cron to shut it down if the cpu goes over 60c
currently it is quite happy mining away (if you can call it that at 100Kh/s) 

running /opt/vc/bin/vcgencmd measure_temp reports the temp=37.9'C

I also installed ufw to give it some sensible iptabling and its great.

btw your graph labels say seccond as opposed to second so I updated the html.
Also as your not likely to cpu mine on it for long people wont care but the graph scale is Mh with a cpu only it implies 100Mh 

Im sure with something plugged in that will be a forgotten memory.

Do you plan on adding a script to pull updates to your work.
I used pacman to update the OS in general

Thanks for your work on this, its brilliant stuff

Gahh, did I ever tell you I am horrably dyslexic?  Thanks for spotting it, fixed in git now (https://github.com/MineForeman/MinePeonWebUI/)

Do you plan on adding a script to pull updates to your work.

Want to try something totally unsupported or tested?  Assuming your useing the latest version as root change into "/opt/minepeon/" and "git pull".  All going well you should get the latest cgminer & bfgminer binaries that support ASIC's (Avalon and BFL).  It is the start of the update system.

Thanks for the testing and feedback, it helps.

My bad, I said it was untested but the plan is to update directly from git.

Also, thanks for fixing the wiki (I assume it was you)

Not me, although if I spot another, will do

I finally broke my last build trying to learn linux so I upgraded to 4-10 The webUI is working great and I have it mining (awesome job with the multiple pools and webUI login!).

The 1 problem I am having is I cannot get screen -r to work anymore

Code:

[minepeon@minepeon etc]$ systemctl status cgminer.service
cgminer.service - cgminer
          Loaded: loaded (/usr/lib/systemd/system/cgminer.service; enabled)

[minepeon@minepeon etc]$ screen -r
There is no screen to be resumed.

sudo screen -r

The mining process need to talk directly to hardware (reliably), best way to do that is to use UID 0 (root).

Ahhh! I will have to get used to using sudo instead of running everything right from root Thanks!

[MineForeman.com]

You can always do;-

sudo -i

and that will give you a root shell .  The privilege separation that I have done is to make sure that if a process is compromised they don't gain access to other processes.  It can be a pain in the ass when your ssh'ed in though so I mostly work as root (I have had yeas of experience at doing it though, don't blame me if you "rm -rf /"   ).

At least with the RPi it is painless when you break things. I have 2 8gb SD cards so when I first broke my last one I just swapped it and was back up and running with the latest minepeon within 1 minute! haha, how many more things can I break now...

Or ... read the FPGA-README ... and set it up properly

[MineForeman.com]

Yeah yeah (how did I know you would bring that up  ).

I am kind of waiting to see how the ASIC's go before doing that.  I want to make sure I squeeze every iota of juice out of them.

Well on the standard rpi distro, cgminer (the only one worth using - none of this crap HW error problems like the other trash) I get 3% CPU for a Jala
https://bitcointalk.org/index.php?topic=138921.msg1952795#msg1952795
so should be the same.
I've only got one working 8GB SD (and the original 2GB that I'm not going to wipe)
I guess I'll get another soon and try out this for a ... day ... I dislike a distro that treats people like idiots ... I use root - always have and always will.

My pi decided to bork so I started from scratch.
git pull isnt working yet :-)

Hi All,

I have had to remove all access to the wiki while I delete all of the spam.  In the mean time I have setup a forum at http://minepeon.com/smf/ .  Logon and request wiki access if you need it.

By the way, people have been asking me for x86 support for minpeon (think GPU and litecoin mining).

If you want it post in this thread;-
