    Do you have Samba installed on it?

    Mind you, the WCG PPD Estimator v0.39b says a Core 2 Duo (Conroe) at 2.4GHz should get 754.29 BOINC/day. Not bad to be beating that number by 45%.

    I'm thinking of moving the main over to the same OS (via virtual machine) since it seems to be crunching so damn well. On the other hand, my Pentium D's output has dropped on the same regiment (HCC), even with its CPU cooling upgrade. It went from roughly 418 BOINC/day to 329 BOINC/day. That machine especially I've been thinking of changing over to Linux (it's just a file server--but I can't figure out how to move the computer over to "WORKGROUP").

    Right click My Computer, select Properties. Then it's the Computer Name tab, then the change button. Hope this helps.

    Won't work. It's an Ubuntu 9.04 AMD64 install, so walk me through the Terminal method or something.

    sudo apt-get install samba
    sudo apt-get install smbfs

    sudo cp /etc/samba/smb.conf /etc/samba/smb.conf_backup
    sudo gedit /etc/samba/smb.conf

    Find this line

    workgroup = MSHOME

    Replace with the following line

    workgroup = new_domain_or_workgroup

    Save the edited file (sample)
    sudo testparm
    sudo /etc/init.d/samba restart

    Linux itself doesn't use workgroups like Windows does so you need something like Samba to allow Windows and Linux to operate in the same environment.

    Installed a ssd drive in my harpertown cruncher. Wouldn't recognize the drive. Went into bios and changed to ahci from ide. Wasn't sure if ubuntu would fire up. It did and my ssd drive is recognized. Do I have to reinstall ubuntu to take advantage of ahci? Or is there a setting I need to change. This is on a asus dseb-dg mobo.

    As far as I can tell Ubuntu doesn't like AHCI for some reason. I've been googling but haven't learned much yet.

    No issues so far. Had no choice if I wanted the ssd to be recognized. Just using it as a scratch disk when I rip movies. Shaves off about 5 minutes ripping to the ssd.

    Hi all, I got a DELL R710 server. And it uses SUSE Linux Enterprise Sever 11(x86_64), there is Xserver program on this server but I don't use it because:
    1. I don't know how to use the GUI interface on the server via my work computer remotely.
    2. The GUI takes some computer resource, maybe WCG runs faster in CLI interface.
    So I just use the command line interface of BOINC program.



    I use PuTTY to remote logon the servers and control BOINC programs, it seems working well.



    I opened 3 PuTTYs to use the server, one to see the BOINC and WCG status(lower left), one to control BOINC program(lower right), the last to see the system status.

    If you are familiar with command line interface of BOINC, it's simple to use BOINC on your Ubuntu or other distributions. You don't have to worry about the GUI, just open several terminals and you can run BOINC too.

    ni hao lidake007

    I used PuTTY for years, forgot all about it.

    What I see that I like is 16 threads!

    There are programs like VNC for viewing and using a desktop remotely. Some are a little faster than others and some have a better reputation for security. You can use a search engine to find them but if you are OK with the command line that is best I think.

    Thanks for the pictures!

    Since you're running Windows on your desktop, search this thread for BoincTasks. It will make things quite a bit easier.

    It allows you to monitor current status, view history and statistics, and change settings from one program for multiple machines.

    Oh HELL yes! Especially running HCC work units. Linux 64bit is anything up to double the speed on those units.

    BUT it also scores LESS points. Not just per unit but overall.

    It's a matter of picking between more points awarded (Windows) or more work completed (Linux), not counting other differences of course.

    I believe they redid the Windows application a little while back and now they are closer to the same for C4CW.

    I just set up my SB Asus P8P67-M Pro mobo and Dotsch/UX won't connect to the internet. Windows connects fine and Dotsch/UX will connect fine on other machines. I'm basically a Linux noob so do any of the resident linux gurus have a suggestion?

    I'm not familiar with Dotsch/UX but here goes.

    Can you ping your router? use the command
    Code:
    ping -c3 <IP-ADDRESS>
    where <IP-ADDRESS> is the address of your router eg 192.168.1.1 or whatever you have on your network.

    DotschUX is based on Ubuntu. Version 8.10 I believe. Can't ping the router. Message says network is unreachable

    It is Ubuntu packaged for small installs to USB or easy setup of diskless nodes and server. So it is just Ubuntu all-in-all.

    At the terminal type ifconfig -a look for eth0 for wired and wlan0 for wireless. If they are not there linux does not reconise or have drivers for that device.

    The easiest thing to do at this point is put in a network card, wireless card or USB network. If you do not have one I can link you some that are known to work with Ubuntu and are cheap. If you are not in a position to buy one I can probably find a PCI network card for here.

    Can you copy and paste the output you get form the command? That might be helpful.

    Linux drivers are for chipsets not brand name. You will need to know the chipset of the network device.

    It's quite possible the interface just isn't configured. I've forgotten to do that while installing a couple of times.

    When I installed Dotsch it seems to me it did not configure the network automatically and I did have to do it manually. Since I started installed Ubuntu 10,x it has done it. So you may be right.
