ssh - share specific folder

Question

linux

Hello, you need to set up ssh on the local computer (ArchLinux, openssh installed). For some user 'test', you need to allow access only to a specific folder on the computer. How to do it?

Answer 1

Google sftp - if you just want to transfer files over ssh.
If it is “locked” in the directory, then chroot, but there are nuances here ...

Answer 2

A chroot is created for this user, and a small world for the user is created there, its own homedir, and the desired folder is already placed there.
The fact is that for any SSH user, the / bin / folder MUST exist in which / bash is located, because the first time you log in, / bin / bash is launched, the user must also see related utilities like iconv, cp (if the implementation is in the form of a binary), php , grep and so on. Without this it will be impossible to work.
Therefore, where the user enters via SSH, there is always a folder /bin, /etc, /dev, /home and so on.
Own / bin, / etc / and other environment for the user takes about a gigabyte (ubunta server).

Answer 5

I don't understand these dances.
after all, you can natively chmod to remove access "for the rest" from all folders except the necessary one.
