Hello,

Further to my previous email here's the missing tcpdumps for the Linux and 
Windows handshake/discovery session when connecting to Telstra Bigponds 
(Australia) ADSL service with PPPoE. My original question still stands, can 
someone tell me why FreeBSDs PPPoE is different to the other packages in 
what it sends? FreeBSD will not connect, the others do.

[Service-Name-Error "SvcName Tag Error"] [AC-Name "nkt1-kent"] [Host-Uniq 
UTF8]


I can see the differences but I don't know if they are the show stoppers. Is 
the fact that FreeBSD puts the Host-Uniq info at the end of the first frame 
the problem or is it something else that tcpdump doesn't pick up? Windows 
puts that info at the start of the frame, Linux doesn't include it at all.

Anyone?

Thanks
