Question Using SFTP


Along with the SSHD service in Linux, SFTP service also comes bundled. Now, I would like to set up SFTP service for particular users who :
  • can only use the SFTP service but cannot login through ssh shell (logging into the ssh shell will enable commands to be executed in the server which could be dangerous)
  • cannot access any other directory except his/her home directory

So, are these possible?

Yes. You have to modify the user's login shell. For example:
Code:
# echo "/usr/libexec/openssh/sftp-server" >> /etc/shells
# chsh -s /usr/libexec/openssh/sftp-server username
Modify the path accordingly to your installation.

You have to setup a chrooted environment for sftp connections. Here is a tutorial about this (you will be interested only in the first part).
