User input for Expect script - expect

Question

I am new to scripting. How can I write an Expect script to ssh into a device and prompt the user for password? We use a pin + RSA token code as the password so I can't store the password.
#!/usr/bin/expect -f
spawn ssh device1

Answer 1

You will need to use the interact command to type in the password yourself.
The below skeleton should get you on your way:
set prompt "$"
spawn ssh user#host
set timeout 10
expect {
timeout {
puts "Unable to connect"
exit 1
}
#Authenticty Check
"*(yes/no)?" {
send "yes\r"
exp_continue
}
"assword: " {
#Hand control back to user
interact -o "\r" exp_continue
}
"$prompt" {
puts "Cool by the pool"
}
}

I have used this code before to achieve what you wish to achieve. You can take it as a reference point to write your own version of the code.
#!/usr/bin/env expect -f
set passw [lindex $argv 0]
#timeout is a predefined variable in expect which by default is set to 10 sec
set timeout 60
spawn ssh $user#machine
while {1} {
expect {
eof {break}
"The authenticity of host" {send "yes\r"}
"password:" {send "$password\r"}
"*\]" {send "exit\r"}
}
}
wait
#spawn_id is another default variable in expect.
#It is good practice to close spawn_id handle created by spawn command
close $spawn_id

The below code will ask the user to enter the password and will use it further in the script where a password will be asked. Just as $pass.
Grabbing password to be used in script further
stty -echo
send_user -- "Enter the password: "
expect_user -re "(.*)\n"
send_user "\n"
stty echo
set pass $expect_out(1,string)
