Setup PuTTY
launch putty.exe
Its this little thing:

Now we start from the bottom to setup PuTTY to connect with your phone.
On the left side look at the "Category" list. Below the entry
"Connection" you can spot
the item "SSH".
Click on it to enhance its view.
You can see the entry "Auth" now - open it with a click.

On the right side you can see "Options controlling SSH authentication"
The standard settings are just fine at the moment. On bottom of this
view click on
the "Browse" button and select your previously generated PuTTY private
key file.
( The putty_private_key.ppk was my example above. )

If you done with that look in the left "Category" after "Data" driectly
under the
"Connection" entry.
Write "user" in the "Login details" first text field "Auto-login
username".

Ok that was almost all to do. Now scroll the "Category" Listview to the
top to "Sessions".

You need to insert there:
At the entry "Host Name (or IP adress) = the IP adress of your android
phone
At the entry "Port" = the port dropbear is using
If you dont know them you get both values from sshControl. Open its
options menu and tip on
the "reload" icon. It take 2-3 seconds to show both values above the
buttons.
( in my example i used IP= 192.168.1.100 and the port number
223 ; Connection type is [SSH] )

Ok lets save this - give a name in the field "Saved Sessions" - i took
"mySession".
and click on the "Save" button to its right side.
Ok that was all!
