identifying my LInux machine on my LAN

[Paul Scott <waterhorse@ultrasw.com>]

My LAN used to have 1 or two computers and/or debices and my Debian 
Linux machine on it.  I used to be able to log in either on the LAN from 
my wife's Windows computer or from outside the LAN with my Debian laptop 
with ssh or Windows machines on which I had installed putty or Bitvise.

I have dynamic DNS hosted by Dyn and I use ddclient.

I currently use DHCP for my Debian machine and have also attempted to 
connect with its local IP from the Windows machine on the LAN.

Now all methods fail.

I don't remember if attachments are allowed but I will attach one 
example of a failure as I possible clue.

TIA for any help,

Paul
