Hi Dimitri, thanks for your help.

I created the script based on yours but it never sends the expect back to
the program.

#!/bin/bash
#!./expect -f 
chmod +r /etc/passwd
chmod +r /etc/group
chmod +x /var

echo "Starting Script"

ssh-host-config 
# Host keys generation is lengthy procedure
set timeout 20

expect {
  "*** Query: Overwrite existing /etc/ssh_config file? (yes/no)" { send
"yes\r";
exp_continue }
  "Overwrite existing /etc/sshd_config file? (yes/no)" { send "yes\r";
exp_continue }
  "Should privilege separation be used? (yes/no)" { send "yes\r" 
exp_continue}
  "Say "no" if it is already installed as a service) (yes/no)" { send
"yes\r"
exp_continue}
  "Enter the value of CYGWIN for the daemon: [ntsec]" { send "\r"
exp_continue}
  "Do you want to use a different name? (yes/no) " { send  "no\r"
exp_continue}
  "Please enter the password for user 'cyg_server':" { send "password\r"
exp_continue}
  "Reenter: " { send "password" }
} 

echo "end First Part"
set timeout 5 

expect {
  "Should this script create a local user 'sshd' on this machine?
(yes/no)" { send "yes\r" }
  "new local account 'sshd'? (yes/no)" { send "yes\r" }
}

I took out the exec so I could see the script run and it simply hangs at the
first query where it asks to overwrite existing files. Is there anything
else I need to do to get this to work with cygwin?
