Linux / Re: Ubuntu Server install
« on: 18 May, 2017, 12:42:04 AM »
One service that I highly recommend is sshd. There is an option in one of the screen to install it. OpenSSH server.

A few useful commands for controlling Boinc from the command line:

Code: [Select]
sudo service boinc-client start
Code: [Select]
sudo service boinc-client stop
Code: [Select]
sudo service boinc-client restart
Code: [Select]
sudo service boinc-client status
When entering text on command line you can use the arrow keys for editing it and tab for name completion.

up arrow will bring previous commands back.

So if you had entered sudo service boinc-client stop hit the up arrow and backspace over op and enter art and you will have sudo service boinc-client start

If you type /var/lib/boi [TAB] the line will complete for you and you will see /var/lib/boinc-client/

Linux / Install Linux from USB stick
« on: 17 May, 2017, 10:53:50 PM »
Just a short FYI.

If you have Mint installed there are 2 programs for this:

USB Stick Formatter
USB Image Writer

There is another program called Disks that will do both tasks, it is also on Ubuntu Mate install and probably installed by most Ubuntu based distros.

If your needs are different here is a comprehensive guild:

Linux / Ubuntu Server install - Headless w/o GUI
« on: 17 May, 2017, 10:29:08 PM »
With temps now getting up to the 90s most of my farm is shut down and what remains runs only at night. I use this time of year to move hardware around and do new installs. Decided to install Ubuntu Server on one machine and Ubuntu Mate on another. It had Mint on it and it was OK but I find the menu lag annoying and I like Ubuntu Mate on another machine so  it got a new install. Also wanted to change hard drives in it.

Most of my hardware is dated. The 2 dual quad core servers that have been running Ubuntu Server for about 6 years now have been 100% always.   No issues and still running fine. So I decided to add a quad core Opteron to the Ubuntu Server count. It had been many years since I installed server and I remembered little of what the processes was like. What kinda surprised me was how fast it went. The download was like 850 megs and of course it did not have the countless libraries and binaries needed to run a GUI as well as not all the word processor, spreadsheet, games and other unnecessary cruft a dedicated headless cruncher doesn't need.

For those curious of what the process is like I found a site that documents all the steps to installing server with pics.

Then it was just a few commands and it was done.

To get IP# for BoincTasks

Code: [Select]
Get Updates

Code: [Select]
sudo apt-get update
Code: [Select]
sudo apt-get upgrade
Install and configure Boinc for BoincTasks

Code: [Select]
sudo apt-get install boinc-client
Code: [Select]
cd /etc/boinc-client
Code: [Select]
sudo nano remote_hosts.cfg
Enter IP# of BoincTask host

To write and close nano


I like to use Boinctui and htop so I installed those.

Code: [Select]
sudo apt-get install htop boinctui

Tip: When at the server and you need more than one screen use ALT F2 and it will give you another login. ALT F3 and etc for more.

Pics below show why I like Ubuntu Server especially on older hardware. Uses little memory, work units get more CPU time, less disk space needed and the system is just quieter with far less going on. Uses 245 megs ram with 4 tasks running, tasks getting max CPU % and used 1.5 gigs disk space.

Anyway to each his own. But this has worked very well for me for about 6 years or so.  ^)(^

BOINC / Re: Checking BoincTasks from browser VIA IP#
« on: 05 May, 2017, 06:04:00 PM »
windows, i'm going away next week and i want to control my rigs. :)

I use the "Team Viewer" application, it's free for non commercial use and it works with Windows, Linux and Android OSes. See here:

You simply install it  on your main rig to create a TEAM Viewer account.  You then install Team Viewer on all your other rigs and use your Initial Team Viewer email address and password to get them to join your manage group. For android devices you download the Team Viewer app from google Store to your phone or Tablet and then use the afore mentioned email and password credentials to join your computer group. (Just insure that you authorize remote access during the Team Viewer Installations.)

Team viewer will let you manage all aspects of any device on your computer group. When away I use a Samsung Tab S2 - 10 inch tablet to monitor and access my computer group. Will also allow you to remotely access relatives or friends computer to troubleshoot or chat.

Site comments, suggestions etc / Shoutbox links help
« on: 28 April, 2017, 09:01:27 PM »
Thought I'd just post a quick how to for posting links in the shoutbox, not least because I sometimes forget myself  ^</
Code: [Select]
To post a link to a web page just paste the address with or without extra text. For example,
For more info go to
then hit send, It will appear as,
For more info go to [link]

To post an image, the link address must have [img] before and [/img] after the
address. You can use the image button to do this for you. For example,
Look at this picture [img][/img]
It will appear as,
Look at this picture [image]

To embed a youtube video in the shoutbox, just paste the youtube link directly with no other text on the line. If a description is needed, make a separate text post before or after. For example,
will show the clickable button
Play Video

GIMPS / Re: Linux GIMPS trial factoring on Pascal Nvidia GPU card
« on: 06 April, 2017, 01:01:19 AM »
I found a script to get work and send results back for the program mfaktc. It works great.

Go to the following link to get it. A few lines down on that page there is a tab called "raw" on the right. Click on it to get the script in a better format. Copy and paste the script into a text file and name it

Put it in the same file as the mfaktc program.

To give it permission to run it I did:

   cd mfaktc-0.21
   chmod u+x

An example on how to run it:

  ./ -u username -p password -n 10

      username is your user name on that had been created
      password is your password
      -n 10 tells the program to have a cache of 10 work units. If you leave it off (-n 10) it just gets 1.

The default of the program sends results and gets work every hour. There is a -t option to change this.

There are other options. You can see these in the program around line 340.

Hardware info, tips & tricks / Re: Ryzen 7 1700 PPW comparison
« on: 16 March, 2017, 10:18:15 PM »
I've just changed my daily driver from i7 6700 to r7 1700.

i7 6700 - 5521 PPD - 89W - 62 PPW
R7 1700 - 10000 PPD - 120W - 85.70 PPW

The R7's PPD is projected, I'll update once I get a decent cooler. The wraith cooler is quiet & suprisingly good for a stock cooler but not good enough to keep crunching 24/7.

This is also on windows 10 and the rig has an extra HDD and a GPU.

With a minimal rig the power consumption should be closer to 100W.
