This article isn't anything I am going to loose sleep over.  Any mission
critical long term TCP connections over an untrusted network (The
Internet) should already be using IPSec.

As for non-mission critical connections, the two parties will just
reconnect at a later time.

Also, unless the attackers know the source port of the client side of
the TCP connection, this attack is useless.  The only way for them to
get the client/source port would be to:

A) Have access to the datastream (if this is the case, you have more to
worry about than them resetting your connection).

B) Have login access to either machine and then run netstat (or a
similar) utility which will tell them the information.
