Autopass

Enter password automatically for sudo, ssh(remote command) and scp, like sshpass.

This is a pure python version which can help you input password for sudo, ssh, scp. For ssh, a yes confirmation is also issued automatically for you if necessary.

No third party module is needed! No need pexpect!

The password-input-matching-pattern is fixed and dedicated for sudo, ssh and scp in source code.

Usage Examples

$ python autopass.py -h
$ python autopass.py -V
$ python autopass.py -p'passwd' sudo <command>
$ python autopass.py [-t300] -p'passwd' ssh username@domain [-p port] <command>
$ python autopass.py -p'passwd' scp [-P port] <file> username@domain:path

You can also export password to AUTOPASS environment variable, this can significantly reduce the exposure of password itself, improve security. Like:

$ export AUTOPASS=password
$ python autopass.py [-t300] ssh -l username domain.com [-p port] <command>

-tN, to specify a timeout in seconds. SIGKILL will be issued to child process when timeout. No timeout by default.

stdin redirection is also supported:

$ export AUTOPASS=password
$ python autopass.py ssh name@domain [-p port] 'bash -s' < script.sh
$ python autopass.py sudo <command> < input

And password can also be redirected into stdin:

$ echo -n 'abcd1234' | python3 autopass.py sudo <command>
$ python autopass.py sudo <command> <<< 'abcd1234'

Password will be issued only once, so if the password is not correct, the child process will wait for a long time. This is your chance to place a timeout. Other cases for using timeout might be the terrible network. You can always place a relatively large timeout value to keep you from waiting like forever.

Autopass is focused on 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 (use &).

Exit code of command is return by autopass, so you can use echo $? in your shell script to check if the command execution is successful.

repeat.sh

This is a very tiny shell script which can repeat your whatever-command forever automatically! When use it with autopass, it would be more powerful!

Usage Examples:

$ export AUTOPASS=password
$ bash repeat.sh python autopass.py sudo <command>
$ bash repeat.sh python autopass.py <ssh command> >> log 2>&1 &

stdin redirection is supported by simple quoting the whole command:

$ export AUTOPASS=password
$ bash repeat.sh 'python autopass.py sudo <command> | <command>'
$ bash repeat.sh 'python autopass.py <ssh command> bash -s < script.sh'

Please do not start a background process by repeat.sh, like the -f option of ssh. It will cause autopass exit immediately. But you definitely could run repeat.sh in background.
