NXClient: using only one screen on a dual-screen system

If you want to use Linux applications remote on a windows box, have a lot of options. But if you have only limited bandwidth, your should use NX from nomachine:

Thanks to its outstanding compression, session resilience and resource management
and its integration
with the powerful audio, printing and resource sharing capabilities of the Unix world, NX makes it possible
to run any graphical application on any operating system across any network connection.
NX accessing remote desktops, servers and applications, whatever
their location, is just as fast, easy and secure as if you were sitting
in front of them.
But if you use a dual-screen system and want to get the remote desktop using both screen, this did not work in the past. But upgrading the client to a version > will do the job. You only have to check "spread over multiple screens" and connect...

Openafs: disconnected network drive?!

You are using the Andrew File System?
You like local caching of files and using YOUR filesystem everywhere you go?
On Linux/Unix everything is quite ok?
But on Windows there are many users complaining about the label "disconnected network drive" for every AFS network drive although the drive is connected and working well?

But there are some solutions to get rid of this label:
  1. Read the mail at openafs-info:
    But this does not work on every windows machine. One thing you should take care of is:
    However, if 
    you are using global drives, the explorer shell will not ever remove those
    newly created GUIDs and it will begin to fill up over time with registry
    entries. This is BAD.
  2. Do not use global drives, if possible.
    But how to get your drives mounted? With openafs clients > 1.5.6 you can not manage local drives within the openafs control panel....
    This is not a problem: Just add a network drive and type "\\afs\yourcell\..." and this will be mounted without this ugly "disconnected network drive"-label....
By the way: Openafs plans to add IPv6 support...

Review at amazon: IPv6 for Enterprise Networks

I was looking for books talking about IPv6. One book i found was:

The summary sounds quite good:
Four leading Cisco IPv6 experts present a practical approach to organizing and executing your large-scale IPv6 implementation. They show how IPv6 affects existing network designs, describe common IPv4/IPv6 coexistence mechanisms, guide you in planning, and present validated configuration examples for building labs, pilots, and production networks.
Finally, they translate IPv6 concepts into usable configurations. Up-to-date and practical, IPv6 for Enterprise Networks is an indispensable resource for every network engineer, architect, manager, and consultant who must evaluate, plan, migrate to, or manage IPv6 networks.
Some chapters are really informative and cover some really nice aspects. But the main chapter (chapter 6) is unclear and confusing:
  • Many Cisco configurations without explanations
  • Many Topics without any grouping and structure
If you have the time to implement the configurations in your lab, then this book might be helpful. But if you only want to read, you should look for an alternative.
If you are interested, take a look at my review at (like all my reviews: written in german ;-).
