    I like sftp much better than regular FTP. Main reason, you can exchange keys for user that use SFTP so there are no passwords. This improves security on your server!!!

    I have followed the exact steps given in the tutorial, but I am getting error in uploading a file. I am able to downlaod any files.
    sftp> put sftp_file
    Uploading sftp_file to /upload/sftp_file
    remote open(“/upload/sftp_file”): Permission denied

    Is SELinux need to be configured anyway?

      Hi Gopal ,

      If Selinux is enable on your linux box , then for Chroot SFTP you need to write SELiux rule “setsebool -P ssh_chroot_rw_homedirs on”.

      I hope this might help you.

      Hi ,

      These steps are tested on CentOS 6.X and RHEL 6.X , i am not sure whether these steps will work on Ubuntu Linux.

      I usually see this error when I don’t have ‘root’ set as the owner & group and 755 for permissions of the user’s directory (‘Jack’ in the author’s example).

    This line needs some improvement

    [[email protected] jack]# chown jack. /home/jack upload/

    1) All the commands above have absolute directory paths. This command make assumption that it’s in the directory /home.
    2) There is a . DOT after jack ? Either a typo or means current directory. See 1.
    3) Why upload/ is this just upload or /home/jack/upload ?

    [[email protected] jack]# cd /home/jack ; chown jack $PWD /home/jack/upload

    • Pradeep Kumar says:

      Hi Fred ,

      I have used . DOT after jack in chown command because i want to make this user both File Owner and Group Owner of upload folder. I have choose upload folder because i want jack user to upload its files and directory on upload directory only.

    I’ve gone through this step by step, but when I try to log in using WinSCP, I get “Error listing directory ‘/upload’ Permission denied.
    Error code: 3
    Error message from server: Permission denied
    Request code: 11

    I can go into the folder, but I can’t list anything, and when I try to upload a file I get Permission denied.
    Error code: 3
    Error message from server: Permission denied
    Request code: 3

    Okay, when I put SELinux in Permissive mode, it works. I’m running CentOS 6, and I tried your setsebool -P ssh_chroot_rw_homedirs on but it didn’t work.

    Sorry for the multiple posts

    These instructions WILL NOT work for Ubuntu Linux and you will effectively lock yourself (admin/root) out if working remotely.

    This solve problem with permission denide on enabled selinux:
    setsebool -P ssh_chroot_full_access on
