Hi all

I'm trying to gather network loads with sigar.jar on my Windows 7 system but sigar doesn't show my network interface:

sigar> ifconfig

        inet addr:0.0.0.0  Mask:0.0.0.0

Is it possible that this could happen because it is a wireless interface?

I'm running the newest java jre + jdk:
C:\Program Files\Java\jre6\bin>java.exe -version
java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode)

I've also tried it with 32 bit jre + jdk but the result was the same. 
On another Win 7 x64 system this worked with a wired interface.

By the way, this is a nice tool for java development ;-)
