I have followed a few examples of how to do this, all of them end up with modifying sshd_config to
Subsystem sftp internal-sftp
Match User chubbyninja
ChrootDirectory %h
AllowTCPForwarding no
X11Forwarding no
ForceCommand /usr/lib/openssh/sftp-server
When I do this, I then sshd -t to make sure there are no errors then service sshd restart
once it's restarted, I try to SFTP (with filezilla) but I keep getting
Response: fzSftp started
Command: open "[email protected]" 22
Command: Pass: ********************
Error: Network error: Software caused connection abort
Error: Could not connect to server
If i revert the config back to its original state, i can SFTP fine, but then i can browse any directory. Where I need users only in their home directory
My default config has this line in it:
Subsystem sftp /usr/lib/openssh/sftp-server
Which is what i'm replacing with the above details.
I only have access to this machine over ssh, although i do have root access.
UPDATE After following sam_pan_mariusz's advice it appears to get further, but now I get
Response: fzSftp started
Command: open "[email protected]" 22
Error: Network error: Connection refused
Error: Could not connect to server
UPDATE 2
I have also followed Froggiz's advice and changed my config to this:
Subsystem sftp internal-sftp -u 0007 -f AUTH -l VERBOSE
Match Group chubbyninja
ChrootDirectory /home/chubbyninja
ForceCommand internal-sftp -u 0007
AllowTcpForwarding no
GatewayPorts no
X11Forwarding no
but I get the original Software cased connection abort
I monitor /var/syslog but nothing shows up to indicate why there's this error
UPDATE 3 - Added sshd_config
# Package generated configuration file
# See the sshd_config(5) manpage for details
# What ports, IPs and protocols we listen for
Port 22
# Use these options to restrict which interfaces/protocols sshd will bind to
#ListenAddress ::
#ListenAddress 0.0.0.0
Protocol 2
