Linux hates you. You must die.

Would help with more info. Error message? Login ok? No projects showing? What? Is this Dotsch? How was Boinc installed?


Make sure the client is running.

sudo /etc/init.d/boinc-client restart

[shoota]

omg information overload. It's Ubuntu 10 i believe, installed from the boinc website. Everything was crunching just fine when i shut the machine down but now when i try to start Boinc manager it won't connect to the local host (whatever that means) this isn't the first time this has happened but i can't remember how i fixed it before. i don't know what else to say. I hit "Connect to Project or Account Manager" and i get an error. nothing more, just says "Error".

Are you using the script in the BOINC directory to start the manager (run_manager) or are you just clicking on/linking to the binary file? (boincmgr) If you do the latter it will misbehave.

[PoppaGeek]

Using apt-get to install sets up the client to start on boot. Installing from the download at Berkly does not so you have to start it manually or setup the startup on boot yourself. That's why it was recommended to install from the apt-get command.

I'm starting it by opening the folder on my desktop and clicking on the file called boincmgr (i think)

But the version in the repos is way outdated so that's why i went with the one on berkeley's site


should i uninstall the version i have and start over?

Leave what you have installed. There's no need to remove it. When you extracted the original file it would have told you to use the run_manager and run_client scripts to kick things over, NOT the boincmgr or boinc files. The others set up the environment variables so the programs can find everything. Just do it that way and you'll be fine.

crap. i think it's @*@&#^$. The biggest problem I have now is that I can't connect to the internet. Neither wired nor wireless. Between this board and linux I'm gonna pull my hair out. I don't even know where to start in getting the internet working again. Any suggestions in network troubleshooting?

[D_A]

Open a terminal and enter

ifconfig

and post the output. You might well have just moved a network cable or something.

So... I can't believe I can't figure this out, but I'm currently at a loss.

I'm trying to install Boinc remotely on a computer I won't have physical access to for two weeks. I used Cygwin to access it and log in, but once I pull it up I can't figure out where I am. If i ls it gives me nothing and .. returns -bash ..: command not found.

The terminal says [MyLogin@Computer ~]$

If it makes a difference it's running CentOS.

I know I'm being an idiot... but yeah.

Edit: wow... forgot the cd for the ..

I might just need a new brain...

Edit 2: So where do I DL and install it to. (This one I dont feel so bad about, never installed anything in linux... which I actually kinda feel bad about. )Here are my options.

[Otis11]

Ah... so now its up and running... but it's only recognizing one processor.

I just emailed a... I guess he's a mentor?... who knows more about this stuff than I do so we'll see what he says.

Anyone know how to get a screenshot of all the threads in CentOS? Cuz that's a pic I wanna see.

[Otis11]

Yet another question for a linux guru when they get around to it...

How can I install, run and control BOINC if I cannot access anything other than a shell?

[D_A]

By using the command line. Everything you can do with the manager can be done with CLI commands as well. Google boinccmd and you should get a list pretty quickly.

[retro77]

I'm thinking about switching to command line on my Arimas. Then uninstall the GUI. I've had weird issues with it. And I don't even touch them except to update WU or reboot for patches.

So Linux gurus; I have been running mainly Ubuntu desktop on my non Windows machines. I have used all versions 8.04 thru 10.10 always the desktop version for ease of installation. I don't use most of them for anything but crunching. I am going to get rid of a lot of P4's this summer most of them are XP machines, old P4 Dells, the electricity is eating me up for the PPD output and the AC to cool the house in the summer. I will probably be getting a couple Sandy Bridges to replace them all but I may want to wait until the P68 MBs are out so I can run without video cards. Now that Ubuntu11.04 is out what crunching improvements could I expect by going to the server version versus the desktop or a lightweight desktop like Lubuntu? More PPD or faster WU processing? Most all machines seem to not have a memory or HD shortage issues at present. These are Intel I5's and I7's and AMD X6's and Athlon II X4's and 3 Sossaman servers that run Linux now. Most all single cores are going away both AMD & Intel. Most are on wired Ethernet. I am not afraid of a CLI interface but haven't had the best of luck to date with putting it all together with Linux to make it do what I want and have had to rely on the GUI's to help get things running.

[D_A]

Running without a GUI will definitely net you both more points and more work completed, the only real question is, how much. Even when you don't have any memory or storage issues, any GUI will be stealing CPU cycles just to keep itself running. Any other additional services, like Bluetooth, will do the same thing, plus the more stuff you have on the system the more it will keep wanting to update so running a server install with only those daemons running you absolutely need will give you the best output from your machine. We're still only talking, MAX, 10% difference if you're lucky, I'd guess.
It's not that challenging to maintain a headless machine via SSH once it's up and running, plus BOINC administration can be done remotely from a desktop machine easily enough. Networking an be a pain from the CLI, but it's no trouble if you set it up at installation.

[bearcatrp]

Need some help on 2 issues.
1. Not sure how this happened but I sold my harpertown rig but kept the hard drive for my next build. I installed it on another PC I was testing and it's in command line mode, not the GUI. How do I revert it back?

2. I have a ATI 6950. Running ubuntu 10.10 64. ATI catalyst is v2. I have to download the latest version manually but can't remember the command to install it once I put the file on my desktop.

Appreciate any help.

q1: You've probably got a different video card in the new system. Hold down the left shift key while it's booting to get into the GRUB menu, then select the recovery option which should be the second one, then in the next menu select the one that refers to reconfiguring the X-server or video configuration or something like that and it will do it itself.

q2: Downloaded the latest version of what?

[bearcatrp]

ATI catalyst. It's at v11.6

What I have now doesn't support my 6950.

Thanks for the help. I will give it a shot.
