TCPDROP(8)               BSD System Manager's Manual                TCPDROP(8)


     tcpdrop - drop a TCP connection


     tcpdrop laddr lport faddr fport
     tcpdrop laddr.lport faddr.fport
     tcpdrop laddr:lport faddr:fport


     The tcpdrop command drops the TCP connection specified by the local ad-
     dress laddr, port lport and the foreign address faddr, port fport. Ad-
     dresses and ports can be specified by name or numeric value.


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

           # fstat | egrep 'httpd.*internet.*<--'
           www      httpd      21307    3* internet stream tcp \
                   0xd1007ca8 <--

     The following command will drop the connection:

           # tcpdrop 80 26747

     If lynx(1) is hanging on a connection again (also works for IPv6)...

           $ netstat -anv | fgrep .80
           tcp        0      0                                 \

     ... then this, easily copy/pasted, will drop the connection:

           $ sudo tcpdrop

     Do not forget the -v option to netstat(1) because otherwise, the IP ad-
     dress may be cut off in the middle.


     fstat(1), netstat(1)
