alt Hacker NewsI wonder if that includes the SFTP server component of openssh?
If so it would be very useful for use with rclone. I back up my phone by running an sshd in termux then using rclone with sftp remotely. This works very well (until the phone decides on a whim to kill the sshd!).
On my LineageOS device, /product/bin contains scp, sftp, ssh, sshd, and ssh-keygen along with a startup script.
In f-droid, there is also a "primitive FTP server" that includes an SFTP, but that probably gets killed unless you are very careful.
