Operating Systems Linux Red Hat How to kill a TCP connection which has status TIME_WAIT & no PID Post 302433490 by fpmurphy on Tuesday 29th of June 2010 10:04:10 PM

There's a utility called tcpdrop on BSDs. Not sure if its ported to any other OS.
BSD's tcpdrop is not available on Linux because Linux does not support the TCPCTL_DROP ioctl (or the equivalent TCP_IOC_ABORT_CONN in Solaris) There is pushback against introducing such an ioctl in Linux every time the issue is raised.

kill(1) 						      General Commands Manual							   kill(1)

Name
       kill - send a signal to a process

Syntax
       kill [-sig] processid...
       kill -l

Description
       The command sends the TERM (terminate, 15) signal to the specified processes.  If a signal name or number preceded by `-' is given as first
       argument, that signal is sent instead of terminate.  For further information, see

       The terminate signal kills processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot  be  caught.
       By convention, if process number 0 is specified, all members in the process group (that is, processes resulting from the current login) are
       signaled.  This works only if you use and not if you use To kill a process it must either belong to you or you must be superuser.

       The process number of an asynchronous process started with `&' is reported by the shell.  Process numbers can also be  found  by  using	It
       allows job specifiers ``%...''  so process ID's are not as often used as arguments.  See for details.

Options
       -l   Lists  signal  names.  The signal names are listed by `kill -l', and are as given in /usr/include/signal.h, stripped of the common SIG
	    prefix.
