I want to write a script that allows me to pass a password to the
su command. The reason for this is to automate the process of logging into root from nonroot account. From my basic understanding of security, I know the dangers of this. I still need this to try to crack the root user password by reading passwords from a file.
I have heard about using the
expect command to automate interactions but I do not know how it works, or if it is applicable in this situation. Any information about using
expect would be greatly appreciated.
Please note that
sudo is not an option as my user is not on the sudoer list.
Things I've tried
- Passing the password in using pipes
Didn't work because of
"su must be used from terminal" type error
- Passing the password using
Whatever was echoed would simply show up after the password was entered
