nsca old server with new nsca client

[Eric Stanley]

Albert,

The packet size was increased in 2.9 that caused 2.9 clients to fail 
with older servers and 2.9 servers to fail with older clients. A fix was 
implemented in the server in 2.9.1 that would allow older clients to 
connect to it, but 2.9 and newer clients will not be able to talk to 
older servers because they still use the larger packet size.

The reason the fix is in the server is because there are far fewer 
servers than clients, meaning less things to replace in order to get 
things working. If you update your server, your older clients should be 
able to connect.

Hope that helps.

Eric
