I have FreeBSD ( build 4.1.1  )  server .
I use SSH client to connect to server.
When i work at the server netstat display one row like this:
tcp4       0      0  x.x.x.x.22       y.y.y.y.61607    ESTABLISHED

If connection has been  broken port does not closed and when i have
connected again netstat display to row

tcp4       0      0  x.x.x.x.22       y.y.y.y.61607    ESTABLISHED
tcp4       0      0  z.zx.zx.zx.22       zy.zy.zy.zy.61348    ESTABLISHED

Now i have five such row when i use netstat to view open ports
command ps -ax display that csh ( shell ) is still executed,
 Then I kill all suspended csh and all ports has been closing . ;-)

My be exist the other way to close the csh while client lost connection ?

Such problem appear then i use ftp client from my server to other server
ftp.
I close ftp client but socket is still open
netstat -an display

tcp4       0      0  y.y.y.y.1034      x.x.x.x.21    ESTABLISHED

what must  i do in order to   connection become  correct ?
