I must be missing something trivial here. If you don't want to display $Pawd, leave it out of the echo:
Code:
echo " connecting to $IP-addr with a password"

Remove the $ from the echo code:

Code:
echo " connecting to $IP-addr and Pawd"

Even telling a hacker how many letters a password is is giving them more information than they need. Don't even bother with *'s.

If you don't want to print it, just...don't.
