Autopass

• Installation
• Usage

Entering password automatically for sudo, ssh (remote command) and scp, like sshpass. However, autopass is a pure Python version script.

No third party module is needed! No need pexpect!

Installation

$ pip install autopass

Usage

$ python -m autopass -p'passwd' sudo <command>
$ AUTOPASS='passwd' python -m autopass [-t<N>] ssh user@domain [-p port] <command>

-p<passwd>, specify the password.

-t<N>, specify a timeout in seconds. SIGKILL will be issued to child process after timeout. No timeout by default.

Password will be issued only once and only in the first line of output for security reason. So if the password is not correct, the child process will wait for a long time. This is your chance to set a timeout. Other cases such as a terrible network, an unknown host or the fingerprint of host is not right, etc, might also need a timeout to prevent from waiting too long. You can always place a relatively large timeout value to keep you from waiting like forever.

Password can also be exported to AUTOPASS environment variable.

$ export AUTOPASS='passwd'
$ python -m autopass <passwd-needed-command>

Autopass is a simple tool only for command execution, locally or remotely. It cannot be used interactively. And please do not start a background process by autopass, like -f option of ssh. It is an error. But you definitely could run autopass with command as a whole in background (by &).

Exit code of the executed command is returned properly, you can use echo $? in your shell script to check if the command execution is successful.
