Hi, macos-10.14.6 macports-2.6.4 OpenSSH_8.4p1, OpenSSL 1.1.1i 8 Dec 2020 (via macports) I've been using ControlMaster, ControlPath and ControlPersist in my ~/.ssh/config for a little while now, and I've noticed a tiny problem that I'd like to fix. If my current working directory is on a removable drive's file system (e.g. a USB stick), and I run ssh/scp to a new host and a new control socket is created, I later find that I can't unmount the removable drive, because the long-running ssh process that holds the control socket open has inherited its current working directory from my shell when I started ssh/scp. I need to terminate that ssh process before I can cleanly unmount the removable drive. If there's no good reason to retain the inherited current working directory, would it be OK to change ssh so that the process that handles the control socket changes its current working directory, either to the root directory, or to the user's home directory, or to the directory containing the ControlPath? I'm happy to supply a patch or pull request to change this if it's worthwhile. Is it? Which directory should the long-running ssh process change to? Changing to the root directory is the simplest thing with the least code, and so would be my preference. But the other choices seem reasonable as well. Thoughts? cheers, raf
