Thanks ICN50. Chris how do you go about installing Boinc in Linux are you able to install it from within Linux (search for it with in the app manage or whatever it is called) or do you have to download it from the official website? If it is needed to be downloaded from the official website I think it would be easier for me to use a Windows based system. Out of interest was your runtimes longer on the 8 cores or was it about the same time as your computer would process (assuming you had a physical machine on the project) Thanks for your help.

You don't need to download BOINC from the website, and it is available from the OS repository by typing a single command. You have all the installation instructions here:

also I noticed that they don't crunch 24/7...you have to leave a connected client to the cloud server!
---------------------------------------- I'm not using Cloud computing (Google, Amazon, etc) because it is still expensive. I'm just using VPS. Crunching UGM (as you can see my current badge), because low memory is OK. I see apologies I never thought to look at your badges. The reason why I mentioned the 2 companies I did is because they come with free credit. I am not interested in paying for such a service then you can also check Amazon...it gives 24h FREE cloud computing for FREE 1 year...but just 1 core of 2,5 E5-Xeon... Speedy51, I ran the Google Free trial for about 60 days. I was able to spin up four virtual machines (2 cores each) running Ubuntu in almost no time. My free trial has now expired. I believe I was running Mapping Cancer Markers at the time. After getting the vm setup I ran the following commands on each one to get them running BOINC. sudo apt-get update sudo apt-get install boinc-client sudo /etc/init.d/boinc-client restart boinccmd --project_attach http://www.worldcommunitygrid.org < insert your Weak Account Key here without the angle brackets > Your Weak Account Key is found under Settings: My Profile. That was pretty much it. I then had 8 cores running 24/7 for 2 months. thx for the tutoring...will try out more VMs on Google! ;) ---------------------------------------- [Edit 2 times, last edit by KLiK at May 14, 2015 10:26:25 AM] |

Everybody who is thinking about renting a root server should consider that he is responsible to secure the rented root server.
----------------------------------------There are some not to difficult steps to perform to secure the server: - Change root password - Change port of ssh - Create new user and password - Forbid root to logon over ssh - Only allow new user to logon over ssh; check that this user can switch to root - Change ssh login to keyfile login and forbid password login on ssh - If you have a fixed IP adress at home only allow login from this IP The only risk in performing this steps is: If you don't work carefully you can lock yourself out of your server. For every step I highly recommend keeping a ssh session alive and test the changes with a second ssh session. In case something went wrong you have on session alive to revert the step(s).

Thanks for your post Eric. Since I have no knowledge of Linux it is probably a better idea that I use either server 2008 or server 2012 if I decide to go ahead with cloud computing?

You're welcom Speedy.
----------------------------------------I'm a newbee in linux too. The changes to secure a linux root server are not that complicated as it may look like. At the moment I'm a little short in time to translate the tutorial I wrote in the wiki of my team to this issue from german to english. I'm not sure how good e.g. google translate will work on the tutorial but you may give it a try: How to secure a root server. Hopefully I'll find a little time to write a brief extract of the wiki tutorial here in english. But feel free to ask. |

Eric it seems Google Google cannot translate the page at all. There is no hurry.

To test, page translation in Chrome works perfectly fine, retaining the full wiki layout. Paste the url from Eric into the address box, enter and right top the offer pops up to translate. Of course, machine translation is questionable, so editing is required before republishing, getting such as "Additional or optional Maßnamen" ;P
