I think this one is another untested rumour Unchecking the use ports 80 and 443 will disable supernode mode. The approach taken by CERN is interesting in the fact that they restrict the use of Skype to port 50123 to allow for better network traffic monitoring, I am not sure that this solution is viable in our environment but it worth consideration, where Fermilab uses procedures based on Firewall settings. … but those that have reverse engineered the protocol suggest that the only playform that has supernode capabilities today is Windows (not even Mac or Linux Skype nodes ever become supernodes). There are further complications with reports that the Mac and Linux clients do not become supernodes, although I have not seen definitive proof of this ‘fact’. In the Skype Universities section they give methods to prevent Skype from becoming a supernode, but these are still mainly applicable to Skype for Windows, and with Skype for Mac OS X being stuck at version 2.7 the future looks none too bright for a 3.x release any time soon. We had our solution for Windows over twelve months ago but are still waiting on a viable solution for our Mac clients.

Is there an ETA on that? – e (2008-Mar-26)

It prevents the use of the linux and Mac clients at many universities. When will we have the ability to disable skype supernode functionality. I think that Skype should come clean about their intentions if they are to be taken seriously as a business tool.

The lack of a roadmap from Skype doesnt do their reputation a lot of good and leaves us looking a bit daft. We have allowed Skype for Windows on our University network but are under a lot of pressure to allow Macs to use Skype as well.
