How-To: Ubuntu cruncher! Install and forget

[D_A]

You'll need to install the right ca-cetificates file then. Someone at Ubuntu, in their "infinite wisdom" did something silly with the certificates, but it's quite fixable. Give me a minute and I'll put a copy of the file up for download and tell you were to put it (nicely of course )

[shoota]

lol! you're da man

Just unzip this file and copy it as root to /var/lib/boinc-client (sudo cp ca-bundle.crt /var/lib/boinc-client ... assuming you've extracted it in your home folder if you put it on your desktop use sudo cp /home/<your user name>/Desktop/ca-bundle.crt /var/lib/boinc-client ) then restart boinc (sudo /etc/init.d/boinc-client restart) and you should be golden

[shoota]

wow i'm utterly speechless. how in the world do you know how to do stuff like that?

[D_A]

I'm studying to be a systems administrator. There's other folk here that have been sys admins for ... long enough they probably don't want to be reminded.

[shoota]

does that have anything to do with computer engineering?

p.s. you're gonna be a good admin

[D_A]

Yes, kind of and not really. All to varying degrees

I'm doing a Bachelor of Information Technology, currently majoring in Systems Administration with a minor in Database Administration and readings in Forensic Science. My original study goal was to work with the Federal Police Cybercrimes Division.

quick question. now that's its up and running, if i need to play with my OC can i pause the work from the simple view, restart the pc, and have it resume work where it left off?

This is what I use for the UBUNTU ca cert problem:

Wordcommunitygrid Message "Peer certificate cannot be authenticated with known CA certificates."

Install the upstream ca-bundle.crt file for BOINC:
1. cd /var/lib/boinc-client
2. sudo mv ca-bundle.crt{,.bak}
3. sudo wget http://boinc.berkeley.edu/trac/expor.../ca-bundle.crt -O ca-bundle.crt.upstream
4. sudo cp -a ca-bundle.crt{.upstream,}

[shoota]

cool. hopefully if someone has this problem that will work for them. D A did the trick for me already tho i still need to know boinc will resume where it left off (like in windows) if i restart my pc?

[D_A]

It will resume from it's last checkpoint, just fine.

[shoota]

cool. another ?. is it possible that sensors and therefore gkrellm are reading my e6420 temps wrong? cuz right now at stock setting across the board it's loading at 79C. i used to be able to OC this thing easily to 3200 and stay cool.. heatsink is installed correctly, this isn't my first go around and yes i'm having stability issues with it. i'm out of ideas.

[D_A]

Is it possible that the sensors are wrong? Definitely. The added issues of instability might suggest otherwise though. I'd be inclined to double check the heat sink mount and make sure you haven't acquired a family of dust-bunnies as well. Also check your core voltage. If you've accidentally left it a notch or so too high you could have issues.

[shoota]

well i have it on my bench.. cleaned out the dust before installed. core voltage was at stock. is it also possible that the chip is just degrading? i bumped up the vcore and it's running still but showing 81C. is there any way to check what the TJMax is set at?

[D_A]

Off the top of my head I'd say you'd have to look it up. If you installed lm-sensors you could open a terminal and type "sensors" and I think it will tell you.

edit: Just tried it ... maybe not. It says something but not sure it's what you're after.

[WhiteFireDragon]

the guide on the first page has setup of the local IP addresses. does this also apply for wireless? some of my machines are unreachable to the router, so i just plug in a wireless network card, and when i try to remotely connect to it using realVNC, sometimes it can't connect after the computer has been on for long periods of time. i'm not sure if it's the router, wireless adapter, windows, or realVNC that causes this problem. this is on win7. i'm suspecting it might be some power saving feature, but after i switched that off, the problem is still there.

if i switched this cruncher to ubuntu would it have this same problem?

[D_A]

I had a system here that I was running on wireless. It would communicate fine on a fresh boot but after a while the wireless would just ... stop. No reason I could find. A reboot always got it going again. I put it down to the wireless NIC going to sleep and not waking up on network traffic, but it wouldn't wake on local input either. I just threw that card in the bin. This was on Win XP, btw.
I'd guess (but that's all it is) that your wireless NIC is to blame and it wouldn't matter what OS you were using it'd do the same thing.

i'm gonna install xp on a separate hard drive right quick. i'll let ya know what Real Temp has to say.

edit: ok real temp on xp is showing 68C tops, so lm-sensors is wrong. not that 68C at stock settings is good by any means but at least i feel better. i think my chip is just degrading from use.. oh well crunch it till it dies!!!!

Just got this running on an Ubuntu 10.04 install. Just did "sudo apt-get install BOINC" and attached WCG. Set preferences to 100% and I was off to the races

[shadowwind]

hello will this work with Ubuntu 11.10 or will it work the same as the 10.04 thanks in advance.
i hate beating my head on the wall so i figured i would ask.

[shifty803]

You can install boinc using the software manager in Ubuntu 11.10.

If you prefer, you can install the client using Ubuntu 11.10 Server edition and text commands. This means you could run the cruncher without a GUI and use SSH to remotely log in from your other boxes.

http://boinc.berkeley.edu/wiki/Boinccmd_tool

sudo apt-get install boinc
boinccmd --lookup_account http://www.worldcommunitygrid.org [login] [password]

*This will give you your account key.*

boinccmd --project_attach http://www.worldcommunitygrid.org [account key]

*Now give it few to download your tasks and you should be up and running.*

boinccmd --_get_state
top

The last two lines will tell you whether it is running the project properly. Use the wiki page to manage any settings you need.

[D_A]

There should be instructions here on how to set the client up so it can be remotely administered using BOINC Manager on another machine so you don't need to use the terminal very often at all once it's set up.
If you can't find it, say so and I'll dig up the exact directory and file names to walk you through it.

[shadowwind]

Thank you. good to know things haven't changed that much in XS fast speedy reply i got it going
now for the ocing part then i will be up and running.

[Plan.B]

Got a new q6600. Going to set it up as an Ubuntu cruncher. About time I stopped relying so much on Windows. I know this is an old thread, but Thanks for the guide.

[shifty803]

I updated my other post. I forgot an important command that is necessary to attach the project to your account.

I really recommend installing Ubuntu Server with openSSH and just use Putty to log in. It's low maintenance... basically just a really efficient cruncher that you can run from your other boxes.

After install of the OS and boinc, do this:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get update

sudo apt-get dist-upgrade
sudo reboot

Do that last part if you want to get the latest server kernel. Those updates always require a reboot to take effect. Since boinc installs as a daemon, it's always running when the computer is on. You can verify by typing "top" and looking for the tasks. (ctrl-c exits the "top" status)
