I get: 000c29ab70960000 The last 4 trailing zeros are not the part of the mac address and I am not sure why these are getting added. I'll have a look at your code. thanks again. usman > Also, I wonder why you call the primGet... twice > > getMacAddressOf: iInterface > | ptr ptr2 nul ret | > ptr := NativeBoost allocate: 4. > nul := NativeBoost allocate: 0. > ptr nbUInt32AtOffset: 0 put: 0. > ret := self primGetAdaptersInfo: nul length: ptr. > ret = 111 "ERROR_BUFFER_OVERFLOW" > ifTrue: [ > | size | > size := ptr nbUInt32AtOffset: 0. > ptr2 := NativeBoost allocate: size. > ret := self primGetAdaptersInfo: ptr2 length: ptr. > ret = 0 "NO_ERROR" > ifTrue: [ > | pip numberOfInterfaces| > numberOfInterfaces := size / IpAdapterInfo instanceSize. > (iInterface between:1 and: numberOfInterfaces) ifFalse:[ ^ nil]. > pip := (NBExternalArray ofType: IpAdapterInfo) onAddress: ptr2 size: > numberOfInterfaces. > ^ (pip at:iInterface ) Address asString]]. > ^ nil > > Phil > > > > > >> >> >>> >>> On Wed, May 6, 2015 at 5:28 PM, Esteban Lorenzano <esteba...@gmail.com> >>> wrote: >>> >>>> >>>> On 06 May 2015, at 17:03, Nicolai Hess <nicolaih...@web.de> wrote: >>>> >>>> >>>> >>>> 2015-05-06 16:40 GMT+02:00 Esteban Lorenzano <esteba...@gmail.com>: >>>> >>>>> >>>>> On 06 May 2015, at 12:10, p...@highoctane.be wrote: >>>>> >>>>> I've loaded your package. >>>>> >>>>> A prerequisite is to load OS-Window to make it work. >>>>> >>>>> >>>>> why? >>>>> in any case, oswindow is already included in pharo4 >>>>> >>>> >>>> OS-Windows (by TorstenBergmann) >>>> >>>> not >>>> OSWindow :) >>>> >>>> >>>> ahhh.
