osmocom.org server outage

For about one week from March 20, 2013 on most of the osmocom.org severs and services have been offline due to a hardware failure in the physical machine that was hosting all the virtual machines related to the project.

As I was on extensive business related travel, I couldn't go to the data center and take care of fixing the problem myself. So we had the hard disks sent to my home in Berlin, obtain a machine that has the neccessary SCA-80 connector for the old-fashioned enterprise SCSI hard disks and then start recovery by means of an old backup in the data center + rsync'ing the changes via my slow DSL uplink.

The good news is: Everything is up and running again on different hardware, and there is no data loss as the hard disk was fully intact.

In the coming weeks, we will migrate the various virtual machines over to a new (rented) physical machine, sponsored by sysmocom.

I'd like to thank

  • zecke for providing emergency recovery for the git server
  • roh for providing an old Sun v20z to mount + read the SCA drives
  • noris.net for mailing the hard disks to Berlin
  • the community for their patience with the slow recovery process

OsmoDevCon 2013-04-04 till 2013-04-07, Berlin

Dear fellow Osmcoom developers,

it is my pleasure to finally announce the date + venue of OsmoDevCon2013:

Date: April 04 through April 07, 2013

Place: IN-Berlin, Lehrter Str. 53, Berlin

Like last year, this is an event for developers of the various Osmocom proejects. Reservation and confirmation of reservation is required.

The event is free of charge. The Room is made available by IN-Berlin e.V., an Internet related non-profit organization. Lunch catering will be sponsored (so far by sysmocom GmbH, but if any other sponsors come up, we are happy to share the cost).

So all you have to cover is your own travel + accomodation costs, as well as breakfast and dinner. If you are an active developer and cannot afford travel/accomodation, please let me know and I'll see if we can do something about it.

If you would like to attend, please send a message to laforge@gnumonks.org applying for registration of the event. The registration deadline is March 5, i.e. one week from now.

There is no detailed schedule of talks yet. I will start a separate discussion suggesting / collecting topics in the next couple of days.

More information is (and will be made) available at http://openbsc.osmocom.org/trac/wiki/OsmoDevCon2013

Further discussion regarding the event should be directed at the osmocom-event-orga at lists.osmocom.org mailing list, to avoid cross-posting over the various project-specific lists.

Best regards and happy hacking,

Harald

osmo-pcu (GPRS Packet Control Unit) v0.1 released

After months of work by Ivan Kluchnikov and Andreas Eversberg, the Osmocom GPRS Packet Control Unit (PCU) has finally reached a point where it makes sense to release a first version: v0.1

There are still a number of limitations and shortcomings, most of which should be indicated in the wiki at osmo-pcu. However, even without hand-over, timing advance loop, power control loop or dynamic link adaption of the coding scheme, it is already a useful implementation for lab-type setups and small, indoor real-world deployments.

osmo-pcu can be used either with osmo-bts on the sysmocom sysmoBTS hardware, or with Fairwaves' branch of OpenBTS on hardware like the Ettus USRP family or UmTRX.

Osmocom User Group Berlin

On April 11, 2012, the OsmoUserGroup/Berlin will have its inaugural meeting.

The idea is more or less in the spirit of Linux User Groups, who in turn have learned from Unix User Groups, etc: A regular meeting where users and developers of the specific software can meet, share their experience and code, and work together improving the project.

Whenever possible, there will be some formal talk in the first part of the meeting.

More information is available at OsmoUserGroup/Berlin.

Registration is not required. Just show up at CCCB on April 11 between 7 and 7.30 pm.

Introducing the Osmocom Continous Integration Setup

The Osmocom project has gained a Jenkins setup that will build the various parts of Osmocom after each change. As part of this setup we have enabled automatically executing tests in libosmocore as part of the make distcheck command, it has been extended to the cellmgr_ng and hopefully will be used in all of our projects in the near future.

It is easy to add new tests and details can be found in this email, an example of integrating test execution with GNU automake can be seen here.

Announcing libosmo-abis

We have finally split the low-level A-bis access routines into a separate library called libosmo-abis. This allows us to re-use the code in a variety of projects outside OpenBSC, such as OsmoBTS.

However, this also means there is now one additional dependency that you need in order to build OpenBSC. However, it should be a simple autoreconf -i && ./configure && make install to build.

More information and tarballs can be found at libosmo-abis.
