NAME

tcpdrop — drop a TCP connection

SYNOPSIS

DESCRIPTION

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

EXAMPLES

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

$ fstat | grep 'nginx.*internet.*<--'
www      nginx      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
