RE: MAC Machines | Bonjour Protocol | OT

Thank you a lot,

so no way to make it work without this software solution ?

Can we buy it ?

Is there any official document on the internet saying that this cannot
work.

I need to convince my client by something on the internet.

Thank you a lot guys for your support.
Samer

There is a custom solution to this issue, unfortunately not available
for public use. I have just checked with the authors, they have embedded

that into their software solution for stock trading. Essentially it
tunnels via TCP whatever is on that group 224.0.0.251. This runs in form

of Windows service or Unix daemon (currently on OSX, Solaris and Linux)
and quite a complex application in itself, capable of intercepting
Bonjour requests, tunneling, conditionally multicasting them into a
destination segment etc etc.

Not sure if it helps. ;-) It is amazing however which ways people take
to make things working. They once hit the problem and just developed a
solution in a matter of week. :-)

Cheers,
A.
