NAME

     tcpdrop -- drop a TCP connection


SYNOPSIS

     tcpdrop laddr lport faddr fport


DESCRIPTION

     The tcpdrop command drops the TCP connection specified by the local
     address laddr, port lport and the foreign address faddr, port fport.
     Addresses and ports can be specified by name or numeric 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

     The following command will drop the connection:

           # tcpdrop 192.168.5.41 80 192.168.5.1 26747
