You cannot kill them, they are not processes but connections that the
kernel's TCP stack is aware of.

man no (network options command), relevant options are tcp_timewait,
tcp_keepidle and tcp_keepint.

You should look at changing the TCP_TIMEWAIT variable, I refer you to
http://publib.boulder.ibm.com/infoce...6r0/index.jsp?
topic=/com.ibm.websphere.base.doc/info/aes/ae/tprf_tuneaix.html.

no -o tcp_timewait = 1 # 15 seconds
