Run X2go thin-client using kiwi-ltsp

September 27th, 2012 by

Recently, came across x2go packages maintained by Jan Engelhardt for openSUSE and other distributions on open build service. As openSUSE Education Li-f-e has great LTSP integration thanks to KIWI-LTSP, I decided to check out how x2go can fit in with this existing thin-client computing solution.

“x2go is an open (GPL/AGPL) source “server based computing” project. Combining the advantages of existing systems it features ease of use, performance and scalability. x2go provides you with access to your desktop – from within your own network and via the internet. x2go is not limited to particular hardware, it supports a variety of devices and architectures.” -from their website.

Some of the features/benefits of x2go that are not available on LTSP are:

* Remote login from within local lan and internet from any OS
* Session persistence, you can disconnect session from one client and continue where you left off from any other client
* Low bandwidth usage
* Session sharing with other users

How kiwi can help to cleanup your system

September 25th, 2012 by

After some iterations of updating the system with zypper dup or yast and some years of service with the system you will find out that there is a lot of dust which is obsolete or has been forgotten. Recently I had the problem that I need to move my 32bit system to a 64bit system and thus the way to go was to migrate the running system into an image description, build a 64bit image from it and install that on the 64bit machine. But the most important part was to cleanup the running system and find out what it really contains. The report kiwi migrate created here was helpful and so I think it might be helpful for others too. Just call:

kiwi –migrate mySystem

It will end up with some data below /tmp/mySystem which of course can be removed at any time without any risk. Most interesting is the html report generated which you can view with any browser. So far kiwi collects the following information:

  • kernel version and kernel specific kmp packages
  • hardware dependent packages
  • installed gem packages
  • repository checkouts
  • rpm packages installed multiple times
  • rpm packages which could not be found according to the current repo setup including version and repo information
  • tree of modified files, packaged but changed
  • tree of custom files, those which doesn’t belong to any package or other part of the bullet list

basically the use case of kiwi migrate is to migrate the running system into an appliance description but I’m not there yet. There is still room for improvement but I think it still can help to cleanup the system and to see what is installed on the system and not managed by a package manager

I have tested this since openSUSE 11.4

Remember to have fun :)

live-fat-stick

September 13th, 2012 by

So you got a bunch of different openSUSE 12.2 live isos downloaded, to test them on a real machine you have to either burn them to CD/DVD or create live USB stick. Creating CD/DVD is a total waste after booting it once or twice. Creating bootable USB stick is a better thing to do, however openSUSE Hybrid iso creates USB stick that is not usable for any other purpose and the remaining space is locked till you make another partition, and even then the partition is not available on windows(tm).
