Here's a posting in ./ to an article about DoS attacks on hash functions.

is LVS susceptible to this sort of attack on the connection hash table?

I would imagine that the client only has a small number of variables (the
port they are sending from?), the others being fixed (CIP, VIP:port).
and probably can't mount much of an attack even if they can choose the
ports at the clients end.
