[Zope] Ping - Dicom Pïng result in Zope page

Hi, I would like to show the result of a ping to an IPAddress in a zope webpage. Is there a specific python library I can use for this with an external method? Or are there other ways? Basicly I need to show that the PC is online or not. (This is only for simple checking) Does there exists Python Dicom libraries? (ie for a Dicom Ping) Thanks, Tom
