Cool new gadget II …

Yeah “The Postman Always Rings Twice” 🙂 particularly ours……..,

I have just received my new gadget. Yes, its a Kinect Cam.

First tests look very impressive and promising. We will use the cam for our AAL project Healt@Home., and for our stundent projects too 🙂

For the first tests I have used the NUI Kinect Driver SDK.

Next steps will be to get the depth data into OpenCV, aForge, ImaqVision,…..

Stay tuned for more…..

How to run Apache 2.2.x with multiple SSL certificates via one IP

I never thought that could be a problem. Well after digging around for HTTP+SSL (multiple certificates) and after understanding how it works, yes this is definitely a problem :-).

But there is light at the end of the tunnel called SNI (Server Name Indication). SNI is an extension for TLS .

The idea behind SNI is that the clients domain name request is deferred until the certificate is exchanged between the the two parties . This gives the server the change to switch to the right named virtual host :-)…. yeah thats cooooool.

See here RFC3546 (Section 3.1) for an in deep description.

SNI works with (according wikipedia):

  • Mozilla Firefox 2.0 or later
  • Opera 8.0 or later (the TLS 1.1 protocol must be enabled)
  • Internet Explorer 7 (Vista or higher, not XP) or later
  • Google Chrome (Vista or higher. XP on Chrome 6 or newer[7]. OS X 10.5.7 or higher on Chrome 5.0.342.1 or newer)
  • Safari Safari 3.2.1 and newer on Mac OS X 10.5.6 and Windows Vista or higher, not XP
  • Any Apple iDevice running iOS4 has support for TLS server name indication.
  • Android

If you want to use SNI for your server you have to put your *.443 hosts configs into one file.

Listen 443

NameVirtualHost *:443

# Also accept connections from none SNI capable hosts
SSLStrictSNIVHostCheck off

# This is our default virtual host.
