Could it be that ssh doesn't use stdin or something for reading the
password..
An alternative way, of not needing to enter the password is to add
your public key to the authorized_keys and/or authorized_keys2 files on
the receiving host.
BTW What happens when you do 'ssh -v -l username -p 1010 hostname "ls
-l"' in the expect script?

| The very same does not work for me !!! Here's the output from my session..

| $ cat connect_ws
| #!/usr/bin/expect -f
| spawn /bin/ssh -l username -p 1010 hostname "ls -l"
| expect -re "Enter passphrase for RSA key '.*': "
| send "shuba\r"
| expect eof
|
|
| admin AT WS007594 ~/scripts
| $ ./connect_ws
| spawn /bin/ssh -l username -p 1010 hostname ls -l
| Enter passphrase for RSA key 'admin AT WS007594': shuba

| <Comments> No output !!

| <Comments> I typed ls - not echoed
|
| admin AT WS007594 ~/scripts

| I believe this is a problem with the way tty's are handled under cygwin.

|
| I think what's going on here is that somehow the ssh's stdin is getting
| "disconnected" from the expect terminal (I don't know whether the
| problem is expect's or ssh's though). This is evidenced by the fact that
| you are seeing the password that expect is typing. Expect is typing
