My tale of IPv6 blues
My ISP provider is KPN. They recently enabled IPv6 in my street. I was using before a IPv6 Tunnel Broker, starting with SixXS and after they went out, with Hurricane Electric. So naturally, I decided to switch to KPN's native IPv6 service. They provide a /64 prefix, which is reasonable. Would be better ...
Secure erase of disc drives
This article is about erasing disc drives securely. Specially for SSD drives, writing zeros or random data to discs is not good enough and counterproductive. One way to do secure erase (for disposal) is to begin with an encrypted disc. However, after the fact the following options are possible: ATA Secure Erase ...

Windows administration from the command line
Windows system administration is very mouse driven and to reach all tools you need to browse through Windows explorer. If you are like me and prefer to log on a limited privilege account and use Runas to perform admin tasks, you can open these consoles with the .msc file names. Here is a list of admin tools with their .msc file names. domain.msc: AD Domains and Trusts ...

Recently I found this Open Source project. Apparently it recently gained support to unpack Exchange Offline Address Book files. What I don't know is after you unpack it, how would you use such a file. Intriguing but apparently falls a little bit short. Probably would need to try it out for myself to see how it works. libmspack. ...

Remote Bridging
Sometimes we need to connect two or more geographically distrubuted ethernet networks to one broadcast domain. There can be two different office networks of some company which uses smb protocol partially based on broadcast network messages. Another example of such situation is computer cafes: a couple of computer cafes can provide to users more convinient environment forr playing multiplayer computer games without dedicated servers. Both sample networks in this article need to have one *nix server for bridging. Our networks can be connected by any possible hardware that provides IP connection between them. Connecting Two Remote Local Networks With Transparent Bridging Technique Short description In described configuration we are connecting two remote LANs to make them appearing as one network with 192.168.1.0/24 address space (however physically, presense of bridges in network configuration is not affecting IP protocol and is fully transparent for it, so you can freely select any address space). Both of the bridging servers has two network interfaces: one (as eth0 in our example) connested to the LAN, and second (eth1) is being used as transport to connect networks. When ethernet tunnel between gateways in both networks will be bringed up we will connect tunnel interfaces with appropriate LAN interfaces with bridge interfaces. Schematically this configuration can be following: +-------+ +-------+ | br0 | | br0 | ...
Automatically adding systems to an AD domain
When using virtualisation it is very common to create template VMs that can be cloned from. This makes deployment much easier than having to install a new VM from scratch. Unfortunately, the cloned VMs lack any Active Directory memberships and the VMs have to be manually added to the AD domain. For automated deployment scenarios this is less than desirable. This recipe intends to solve that issue in a ...
