It is possible (and if so how?) to kill off, manually or otheriwse, a tcp 
connection which is the LAST_ACK state (as shown by netstat)? 

The client side does not appear to be sending a FIN before closing 
its side of a telnet/rlogin connection. This is leaving the server with a 
number of connections in LAST_ACK state with sometimes 30K each of bytes 
in the Send-Q (again, according netstat).

I'd like to find a way to zap these connections (with out shutting down 
the rest of tcp/ip). (Unfortunately, I can't do anything about the client 
side of the connection).

This is on a system running SCO UNIX and SCO TCP 1.2.1.
