Setting up SFTP on UBUNTU

How to setup FTP server on ubuntu 14.04 ( VSFTPD )

FTP is used to transfer files from one host to another over TCP network. This article explains how to setup FTP server on ubuntu 14.04 .
There are 3 popular FTP server packages available PureFTPD, VsFTPD and ProFTPD. Here i’ve used VsFTPD which is lightweight and less Vulnerability.

Setup FTP server on Ubuntu 14.04

Step 1 » Update repositories .
krizna@leela:~$ sudo apt-get update
Step 2 » Install VsFTPD package using the below command.
krizna@leela:~$ sudo apt-get install vsftpd
Step 3 » After installation open /etc/vsftpd.conf file and make changes as follows.
Uncomment the below lines (line no:29 and 33).
write_enable=YES
local_umask=022
» Uncomment the below line (line no: 120 ) to prevent access to the other folders outside the Home directory.
chroot_local_user=YES and add the following line at the end.
allow_writeable_chroot=YES» Add the following lines to enable passive mode.
pasv_enable=Yes
pasv_min_port=40000
pasv_max_port=40100

Step 4 » Restart vsftpd service using the below command.
krizna@leela:~$ sudo service vsftpd restart
Step 5 » Now ftp server will listen on port 21. Create user with the below command.Use /usr/sbin/nologin shell to prevent access to the bash shell for the ftp users .
krizna@leela:~$ sudo useradd -m john -s /usr/sbin/nologin
krizna@leela:~$ sudo passwd john

Step 6 » Allow login access for nologin shell . Open /etc/shells and add the following line at the end.
/usr/sbin/nologin
Now try to connect this ftp server with the username on port 21 using winscp or filezilla client and make sure that user cannot access the other folders outside the home directory.

Please note using ftp on port 21 is a big security risk . it’s highly recommended to use SFTP. Please continue for SFTP configuration

Secure FTP ( SFTP )

SFTP is called as “Secure FTP” which generally use SSH File Transfer Protocol . so we need openssh-server package installed , Issue the below command if it’s not already installed.
krizna@leela:~$ sudo apt-get install openssh-server
Step 7 » Create a new group ftpaccess for FTP users.
krizna@leela:~$ sudo groupadd ftpaccess
Step 8 » Now make changes in this /etc/ssh/sshd_config file.
» Find and comment the below line
Subsystem sftp /usr/lib/openssh/sftp-server and Add these lines at the end of the file.
Subsystem sftp internal-sftp
Match group ftpaccess
ChrootDirectory %h
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp

Step 9 » Restart sshd service.
krizna@leela:~$ sudo service ssh restart
Step 10 » The below steps must be followed while creating Users for sftp access.
Create user john with ftpaccess group and /usr/bin/nologin shell.
krizna@leela:~$ sudo useradd -m john -g ftpaccess -s /usr/sbin/nologin
krizna@leela:~$ sudo passwd john
Change ownership for the home directory.
krizna@leela:~$ sudo chown root /home/johnCreate a folder inside home directory for writing and change ownership of that folder.
krizna@leela:~$ sudo mkdir /home/john/www
krizna@leela:~$ sudo chown john:ftpaccess /home/john/www

Now try to connect server using SFTP ( port : 22 ) and makesure Users can upload files to www directory and cannot access other folders outside home directory.setup FTP server ubuntu 14.04
If you want use both FTP and SFTP together, please perform above steps ( Step 10 ) while creating users . For existing users, move them to ftpaccess group and create folder structure and ownership changes as below.
krizna@leela:~$ sudo usermod john -g ftpaccess -s /usr/sbin/nologin
krizna@leela:~$ sudo chown root /home/john
krizna@leela:~$ sudo mkdir /home/john/www
krizna@leela:~$ sudo chown john:ftpaccess /home/john/www

Now john can able to upload files to www folder using FTP as well as SFTP.
