User account and SSH: I need advices...
I have to do the following:
- create a new user on my linux box (red hat 8) that has a public IP
- this user must have access with full privileges (creation, editing, deletion of files and directories) ONLY AND ESCLUSIVELY to a directory that I decide (and that is not his home directory); he must NOT view other directories in any way
- moreover each time this user connect from his win machine to my linux machine using SSH (with user name and password) he can access ONLY AND ESCLUSIVELY the directory I assigned to him (I repeat: not his home).
How can I do this?
How can I configure sshd to obtain what I want?
How can I configure sshd to let ONLY some users (NOT root) connect to my machine?
Thanks in advance to anyone who can give me help...
Please explain your motivation - what do you want him not to see?
The way to make his access as limited as possible is to put his user on his own group. But if all this user needs to do is to ftp then I would suggest some other seperate server software to control his access that doesnt give the user a shell.
well you can grab a web app that allows uploads and downloads over https and auth_digest or something similiar. My point being if you don't trust this person at all and you have senesitive data on the machine giving this person access to openssh in any regard is probably not a good idea. There are also other ftp servers that are "secure", whereby you can limit all access to a particular directory..

There's actually a project, I think on Sourceforge, for "sftp-only" accounts. Basically it's the same idea as having a "nologin" shell, accept they must be able to authenticate as the user for SFTP, but you don't want them to be able to SSH into the machine.
I wish I had the link to it off the top of my head, but 2 minutes on Google should dig it up.
