NAME
     tcpdrop - drop a TCP connection

SYNOPSIS
     tcpdrop local-addr local-port remote-addr remote-port
     tcpdrop local-addr:local-port remote-addr:remote-port

DESCRIPTION
     The tcpdrop command drops the TCP connection specified by the local ad-
     dress local-addr, port local-port and the foreign address remote-addr,
     port remote-port.  Addresses and ports can be specified by name or numer-
     ic value.

EXAMPLES
     If a connection to httpd(8) is causing congestion on a network link, one
     can drop the TCP session in charge:

           $ fstat | grep 'httpd.*internet.*<--'
           www      httpd      21307    3* internet stream tcp \
                   0xd1007ca8 192.168.5.41:80 <-- 192.168.5.1:26747

     Either of the following commands will drop the connection:

           # tcpdrop 192.168.5.41 80 192.168.5.1 26747

           # tcpdrop 192.168.5.41:80 192.168.5.1:26747
