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.

EXIT STATUS

The tcpdrop utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

If a connection to httpd(8) (ports/www/apache2) is causing congestion on a network link, one can drop the TCP session in charge:

# sockstat -c | grep httpd
www httpd 16525 3 tcp4 \

192.168.5.41:80 192.168.5.1:26747

# tcpdrop 192.168.5.41 80 192.168.5.1 26747
