Case story: move the location of Revit Server 2012 models

Share with:


Here is the other issue: due to the fast install of Revit Server 2012, the location of model was not important. After the server’s role was changed to “Central” instead of ‘Caching”, i wanted model be stored in more predictable location.

Again, I had no wish to reinstall the whole server, including w2008r2 server.

Case story: change role of Revit Server 2012 without reinstall

Share with:


Our company was running a caching Revit Server 2012 instance, to be able to work on a project. The central server was set in the kingdom of far away and was serving three architectural offices.
Recently we had to take care of the model created and the Revit Server 2012 instance itself. I hate to touch working system, but i had to.

Where is my free space, windows, where is my free space?

Share with:


I had a strong wish to install Autodesk Revit 2013 just a days ago. Besides it needs 38 GB of free space, it did not fit on my clogged 100 GB system drive.
Too bad. Ok, my drive is oldish 160 GB Seagate, but still, windows7 seems like a disc hog.

So i’ve decide to investigate the case. Using RidNac, i made a small tour to the HDD space. Read the rest of this entry »

Using Revit Server 2012 by non-domain members

Share with:


The last issue in the Migration Hell was Revit Server. To be precise, not the application itself, but the client authentification.
With all it’s bells-n-whistles, it lacks most part of the documentation. The application itself runs on IIS, uses Windows (NTLM) or Basic authentification, but nothing is said about the Revit client. The only thing you can find – you must login as domain member to use the Revit Server.

It’s not true. You should, but must not.

Two things must be done on the client to use Revit Server:

  1. authenticate in the domain and every server you will need to use. You must use your domain login credentials to authentificate. The AD domain uses trust relations to authentificate you in the domain servers. If you prefer not to login to AD domain, you must take care of it by yourself
  2. change environment variables.
    • %USERDOMAIN% point to the current domain, if logged as domain member. If not, it’s pointing to the computer name. Setting the variable to the domain name needed (eg. SET USERDOMAIN=MYCOMPANY) will do the job. You should not use DNS domain name, eg. MyCompany.COM, it’s set in %USERDNSDOMAIN% and is useless in the case of Revit Server
    • %USERNAME% must be set to your AD’s username, without AD prefix or FQDN suffix. Eg. if your AD domain login is mycompany.com\PerfectUser or PerfectUser@Mycompany.COM, use “SET USERNAME=PerfectUser”.

That’s all. Enjoy.

PS: if you use Local Revit Server, and Central Server is located somewere in the Other Domain, you will probably need to authentificate to the Central Revit Server too. Not sure about this.

is the only missing keyword, OpenVPN client-to-server config need to work correctly on the client.
It took me 3 days to figure this out, a lot of RTFM’ing and head-banging.

Full client config looks this way:

Get rid of removed packages in Debian

Share with:


Every time package is removed via `apt-get remove`, a tiny piece of its configuration can be kept in your system. If you ever need to reinstall the package, this information can be re-used. These packages has status ‘rc’ in the output of `dpkg -l`. But if you want to keep your system tidy and clean, you may want them to be removed.

The miraculous command is

dpkg -l | egrep ^r | cut -d ‘ ‘ -f 3 | xargs apt-get remove –purge -y

OpenOffice.org, x64 and .NET interface

Here,’s the story short:

I need to create a series of graph for highly scientific data sets. The data is calculated in MatLAB, but the export of figures in MatLAB is a pain for me.

On the other hand OpenOffice.org seems to be the right tool for the job. The latest MatLAB has the function, called ‘xlswrite’. Happy with the fact, hoping it should write the XLS file I fire it up and…

Ouch. One must have Excell installed, as the data export goes through the ActiveX. If no Excell is found, the data is exported into CSV file, overwriting the file every time. Not the Right Thing. Read the rest of this entry »

Running VirtualBox guests from physical drive

Share with:


Dual boot is perfect solution in most cases.

On the other hand, if you need to peep into the other system’s files, you need to re-boot. Or use sometimes not so stable filesystem utilities.
Running fully virtualized OS, using eg Xen as supervisor, creates additional load an hardware, maybe not too big when running multiple OS’es on the pretty new server, but significant, if it is a laptop. And yes, you NEED to keep data in-sync between virtual and real OS. Read the rest of this entry »
