wmic Compile Instructions from Matthieu Thibault's Site

NOTE: There is now a comprehensive installation example here.

Original Information

Before being able to use it, you will have to compile wmi-client for Linux.

2. Install stuff on the Linux box to support compiling (package names may vary depending on you Linux distribution)
apt-get install autoconf python libdatetime-perl make gcc

3. Download stuff
This is actually from the Zenoss project, to whom most of the credit should go:
http://dev.zenoss.org/svn/trunk/inst/externallibs/wmi-1.3.13.tar.bz2

4. Bunzip and untar stuff
bunzip2 wmi-1.3.8.tar.bz2
tar -xvf wmi-1.3.8.tar

5. Make
cd wmi-1.3.6
make

6. Find something else to do for at least 10 minutes, compiling takes time

7. Test it
wmic -U DOMAIN/USER%PASSWORD //HOST "Select * from Win32_ComputerSystem"
You should get lots of information from your target Windows machine. Be careful, wmic requires a forward slash and NOT a backslash between the domain and username.
