We have the base64 encoded SSH key password (so not a user account password!). We have to keep an SSH tunnel opened to a place. But sometimes the connection is bad and the SSH session terminates. When we start the SSH tunnel, the SSH private key is encrypted with a password, thus requiring a human to input the pw. We know that it is just obscurity to have the private ssh key password in a file, but it helps :)Question: How can we automate the pw input when we open the tunnel? Maybe expect can help?
