[ale] force close a connection?

[Tim Watts]

I have a remote desktop connection that's stuck open after the wireless
AP on my router hung. How can I kill the connection on the remote host
other than by being patient?

Here's the relevant netstat output at the remote in case I'm not being
totally clear:

$ netstat -atn
Proto Recv-Q Send-Q Local Address           Foreign Address
State
	<snip>
tcp6       0      0 192.168.2.50:5900       192.168.2.51:43048
ESTABLISHED
tcp6       0  11543 192.168.2.50:5900       192.168.2.51:48928
ESTABLISHED

I want to kill the 2nd connection.
