in thread how to send input to stdin automatically?

ssh (as most programs asking for a password) does not read the password from stdin but from the process tty, so not opening a pipe neither using any of the modules you have named will work.

The usual solution to automate password authentication is to use Expect.

Log In?
Username:
Password:

What's my password?

[stevieb]: I don't know what you mean. I write the code in C/C++ that accesses the ICs per the datasheet, wrap it for Perl, then use them. My code ensures that the functions/methods from Perl do the right thing for the chips/sensors etc
[stevieb]: At least that's what I'm working on right now. I've also been updating my automated test software Test::BrewBuild so it handles this work properly. It's not really easy meshing high level languages with low-level hardware :)
[stevieb]: this link is probably better for an overview of my test software
