using scp to upload to sourceforge to a path with spaces

The titles says it mostly, if you want to upload a file from a linux machine to the FRS on sourceforge, but you have spaces in your paths:

scp (file_to_upload) (my_user)”/home/frs/project/(project_name)/Path\ with\ spaces/”

Easy, really, if you know all the details to watch out for:

  • enclose the path (everything behind the column) in double quotes (“)
  • Escape each space in that path with a backslash (\)

If you don’t enclose the path with double quotes, you’ll get the following error message :

scp: ambiguous target

The following variables are used in the example:

  • (file_to_upload): the name and path of the file (if you’re not uploading from the folder the file is stored in) of the originating machine
  • (my_user) : your username
  • (project_name) : the path for your project. On sourceforge, sometimes you may need to add a few folders in front with the first and the first two letters of your project name : /p/pr/project

multiple folders in one zip file under linux

I keep forgetting the syntax for adding multiple folders under one zip file under linux.A small reminder to myself, and maybe it can help others as well (although it’s easy to find on the net).

The command to do that is quite straightforward/easy though :

zip -9 -r <zip file> <folder name>

the ‘-9’ tells zip to use the best compression, while the -r indicates you want to have zip do a recursive operation on all subfolders below the folder you mention.

Skype installeren op OpenSuSE 11.2 64-bit

When you install Skype on a 64-bit OpenSuSE 11.2 system using the installation package on the Skype Linux page, Skype refuses to start after install. When looking at the command line,you get the following error message:

That seems to be an issue with a bad installation package from Skype.

Luckily, Alberto Passalacqua describes on his blog the  correct installation procedure to get  Skype 2.1 on OpenSuSE 11.2 64-bit. I did this on our older laptop which is still running OpenSuSE 11.2, and it works great.

Thanks, Alberto!

OpenSuSE 11.3 released

Today the OpenSuSE project unleashes its latest offspring to the world. OpenSuSE 11.3 is finally officially available.

During my last installation, 11.2 at the time, more than a month after the release, I bumped into some serious errors (older AMD graphics cards had issues in a vanilla 11.2 install, the so-called black screen error – here and here) I decided I wouldn’t be a beta tester this time and give it some time.

It all looks nice and shiny, and one can see immediately that the linux world is growing up. Many distributions are making deals with companies to bundle various services.

No WPA with bcm4306 on OpenSuSE 11.0

A few days ago, there was a newly released version of the OpenSuSE kernel available in my update list. After download and installation, my bcm4306 wifi adapter was finding multiple broadcasted signals with associated networks. Sadly, it seems that encryption support isn’t yet working in this configuration, as I can’t seem to connect with my secured network at home.

No connection with BCM4306 on OpenSuSE 11.0

I’ve been trying for several days on and off now, to get the previously working Wifi under OpenSuSE to work, now that I installed the new-and-shiny 11.0. I’ve had some success in the past days, but none of those efforts were reproducable i.e. I couldn’t repeat the actions it seems were needed to get a connection.

On the OpenSuSE forums, it seems there is a bug in the firmware of the Broadcom Wifi Chipset 4306, which fortunately can be fixed. I’ll keep you updated on that. If this should work, that means one of the most difficult things remaining during an installation of a new linux finally will be fixed with native software (bc43 driver instead of a hand-configured ndiswrapper). I’m looking forward to the next installation 🙂

eID on OpenSuSE 10.3 – second try

Today, I tried for the second time to use my electronic ID card (standard issue in Belgium since a few years) with OpenSuSE 10.3. I work on a project at the regional Flemish Government at the moment, currently with tasks concerning access control to applications. Even if the eID card is a federal program, the regional governments have access to the resources when they want or need to.

This brought back my interest for the eID. Last time, it was the fact that I had to file my tax declaration, so there was limited time to test. This time, there wasn’t any deadline or rush. Continue reading eID on OpenSuSE 10.3 – second try

e-ID with openSuSE 10.3

I like OpenSuSE. It, and its predecessors without the ‘Open’ part in their name have been my Linux environments of choice since my university days, back from SuSE 6.4. My use of Linux as an operating system has been steadily increasing, almost at the same pace of the quality and the possibilities of the applications the OS provided me with.

Belgium has invested quite some effort in what is called here the e-ID. It’s a smartcard used as identity card, with the added functionality of electronic signatures that are protected by a PIN code. One of the killer applications is considered Tax-On-Web, where one can do his tax declaration online.
