Usually it works well to have this disabled in ftp(1) and in the cases where your TCP connections go via a state table with short timeouts (crappy hotel nat etc), use the OS TCP keepalives instead; set net.inet.tcp.always_keepalive=1 and reduce net.inet.tcp.keepidle from the default (iirc this value is measured in half-seconds in which case the default is 2 hours).
