I have a bash script that has expect to login to a remote host and run list of commands. It works as expected. It has a flaw, if the user enters the wrong password, the expect script keeps trying the password for multiple times. Some host on network are now updated to block the newer ssh connection if there was multiple ssh failure in the recent for some minutes. I am trying to modify the script so the expect breaks/exits the code if the password is wrong on the first attempt.
