Install and Configure SFTP server on ubuntu 16.04 (Xenial Xerus) server
Sponsored Link
MySecureShell was created because of the lack of file transfer features in OpenSSH. OpenSSH was not designed as a file transfer solution, that’s why we made MySecureShell.
MySecureShell Features
Bandwidth control
Only authorized files and folders can be shown
Advanced logging information
ACL can be made with IP/Usernam/Groups/VirtualHost/...
Confined environments (chroot, which is also available in the latests version of OpenSSH)
Restrict users to have sftp only (shell access is disabled by default)
Install MySecureShell on Ubuntu 16.04 Server
Open the terminal and run the following command
sudo apt-get install mysecureshell
This will complete the SFTP server installation.
Add users for MySecureShell
You can add users using useradd command .You can also update the existing user account to get access to MySecureShell server by edit the /etc/passwd file.
Add New User
sudo useradd -m -s /usr/bin/mysecureshell test1
sudo passwd test1
Adding Existing user to MySecureShell Server
From Command line
sudo usermod -s /usr/bin/mysecureshell test2
or
sudo vi /etc/passwd
Change columns "shells" and replace it by "/bin/MySecureShell".
test2:x:1006:500:DSE Testing:/home/sftpusers/test2:/bin/sh
Become
test2:x:1006:500:DSE Testing:/home/sftpusers/test2:/bin/MySecureShell
Save and Exit the file.
You can test your SFTP server using any SFTP client or from ubuntu system use the following command

How to check who is connected to SFTP server
Use the following command to check who is connected to SFTP server
sftp-who
How to Control of bandwidth
You need to edit the /etc/ssh/sftp_config file and Global Download tag allows to limit the maximum download bandwidth for the overall server.
Example
In this example, all users will be able to download up to a 100k maximum bandwidth and the total maximum bandwidth allowed for the server is 1M
<Default>
Home /SFTP
GlobalDownload 1M
Download 100k</Default>
Check Mysecureshell Documentation for detailed configuration options.
I used the above tutorial for installing sftp server on ubuntu. After that i am not able to ssh the instance. I am getting following error
Shell access is disabled. connection closed.
Same issue for me, limited troubleshooting at this point but it appears to have conflicted with OpenSSH. I’ve tried changed the port in the sshd_config file and that doesn’t appear to have helped.
Try the following one and may be not secure
Comment out sftp support in sshd_config and restart sshd service
#Subsystem sftp /usr/lib/openssh/sftp-server

To anyone reading this and having “Shell access is disabled. connection closed.”
By default, ssh access is deactivated for all users, only sftp is enabled. If you want to enable ssh access too for some (or all) users, then you have to create a group with those users and edit the configuration file located on /etc/ssh/sftp_config as explained on the official documentation:
