That was exactly my point. The server only answers "6" when I'm using an older 
release (up to 2.1d). The two logs I posted were done with two different 
versions of rtmpdump, but I ran rtmpdump with exactly the same command line in 
both cases. So I was contacting the same server with the same parameters. 
Using rtmpdump-2.2 (or later) results in the Handshake 9 problem, using old 
rtmpdump-2.1d does not!

Obviously, the server I am contacting does allow pre-10 flash and handshake 6. 
Still, rtmpdump-2.2 or later can't perform the handshake in a succesful way.

I think I have read all recent mails regarding the handshake problem. I still 
thought I was adding new information to the discussion.

You are welcome.

Cheers, Sven.
