Full Discussion: SFTP user include/exclude without preventing SSH login
Operating Systems Linux Red Hat SFTP user include/exclude without preventing SSH login Post 302784453 by jim mcnamara on Friday 22nd of March 2013 08:29:31 AM

Possibility:
OpenSSH has chroot functionality in current versions. On the type of subsystem. Basically you just need to add lines like below to your
Code:
/etc/ssh/sshd_config file.

Code:
Subsystem sftp internal-sftp

Match group sftpusers
     ChrootDirectory /var/www/someplace/safe
     X11Forwarding no
     AllowTcpForwarding no
     ForceCommand internal-sftp

Next create a group sftpusers with command
Code:
groupadd sftpusers

The last step is then to create a user belonging to group sftpusers:

Code:
useradd -g sftpusers -d /var/www/xy/backup/files username

restart your ssh service:
Code:
/etc/init.d/sshd restart

This only affects sftp access only. And users in the sftpusers group only.

/var/www/someplace/safe is completely your decision. All this is on the assumption that I understood what you want. What you presented seems an almost unworkable melange of stuff as is. So feel free to ignore this.
