[ns] When Ftp end?

["Xiaojun Cao" <xjcao@263.net>]

Hi,ns-users,
Suppose I have several FTP running on TCP connection. And the ftps start
like this way:
$ns at 0.1 "$ftp1 producemore 5000"
...
That also means I want they transfer some definite packets. How can I know
when they finish the transfering?


Thanks!
