[Spread-users] Problems with more than 2 hosts in a segment

[Yair Amir]

It is strange that it takes 30 seconds to complete the membership (as opposed to 5 or so).
In addition to George's question I would like to check whether the broadcast address 172.21.1.255 works properly on all of the machines (send and receive). That can be checked using "s" and "r". You might need to build them but they are in the make file.
Run "r usage" and "s usage" to see how they work.

    Cheers,

    :) Yair.
