Setup FTP Server step by step in CentOS 6.5

This tutorial shows you how to install and configure FTP server in CentOS 6.5. Though the steps provided here are tested in CentOS 6.5, it should work on RHEL 6.x(x stands for version) and Scientific Linux 6.x too. In this tutorial my ftp server ip and hostname are 192.168.1.200 and mainserver.ostechnix.com respectively. I have already configured a local repository and I am going to install FTP from my local repository. For more information navigate to setup your local repoistory in CentOS 6 / RHEL 6 / Scientific Linux.
Before proceed, stop the firewall.
[[email protected] ~]# service iptables stop
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[[email protected] ~]# service ip6tables stop
ip6tables: Flushing firewall rules:                        [  OK  ]
ip6tables: Setting chains to policy ACCEPT: filter         [  OK  ]
ip6tables: Unloading modules:                              [  OK  ]
[[email protected] ~]# chkconfig iptables off
[[email protected] ~]# chkconfig ip6tables off
[[email protected] ~]#
Now let us install FTP service.
[[email protected] ~]# yum install -y vsftpd
[[email protected] ~]# Start vsftpd service.
[[email protected] ~]# service vsftpd start
Starting vsftpd for vsftpd:                                [  OK  ]
[[email protected] ~]#
Enable vsftpd in multi-user levels.
[[email protected] ~]# chkconfig vsftpd on
Now edit the /etc/vsftpd/vsftpd.conf file. Uncomment and edit the lines in the vsftpd.conf file which are shown in bold.
[[email protected] ~]# cat /etc/vsftpd/vsftpd.conf 
# Example config file /etc/vsftpd/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
#anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# The target log file can be vsftpd_log_file or xferlog_file.
# This depends on setting xferlog_std_format parameter
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
#chown_uploads=YES
#chown_username=whoever
#
# The name of log file when xferlog_enable=YES and xferlog_std_format=YES
# WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log
#xferlog_file=/var/log/xferlog
#
# Switches between logging into vsftpd_log_file and xferlog_file files.
# NO writes to vsftpd_log_file, YES to xferlog_file
xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
#idle_session_timeout=600
#
# You may change the default value for timing out a data connection.
#data_connection_timeout=120
#
# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
ascii_upload_enable=YES
ascii_download_enable=YES
#
# You may fully customise the login banner string:
ftpd_banner=Welcome to OSTECHNIX FTP service.
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
#chroot_local_user=YES
#chroot_list_enable=YES
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
ls_recurse_enable=YES
#
# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
listen=YES
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd with two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
use_localtime=YES
Now let us restart the vsftpd service and try to connect to ftp server.
[[email protected] ~]# service vsftpd restart
Shutting down vsftpd:                                      [  OK  ]
Starting vsftpd for vsftpd:                                [  OK  ]
Connect to the ftp server.
Note: Root is not allowed to connect to ftp server by default for security purpose. So lets us create a new user called ostechnix.
[[email protected] ~]# useradd ostechnix
[[email protected] ~]# passwd ostechnix
Changing password for user ostechnix.
New password: 
BAD PASSWORD: it is based on a dictionary word
Retype new password: 
passwd: all authentication tokens updated successfully.
Connet to FTP server using the new user ostechnix.
[[email protected] ~]# ftp 192.168.1.200
-bash: ftp: command not found
[[email protected] ~]#
Oops! ftp package is not installed. So let us install ftp package first.
[[email protected] ~]# yum install -y ftp

[[email protected] ~]#

Again connect to the FTP server.

[[email protected] ~]# ftp 192.168.1.200
Connected to 192.168.1.200 (192.168.1.200).
220 Welcome to OSTECHNIX FTP service.
Name (192.168.1.200:root): ostechnix
331 Please specify the password.
Password:
500 OOPS: cannot change directory:/home/ostechnix
Login failed.
ftp>
It shows a error that the user cannot change to his $HOME directory. Type exit to return back from the ftp console and allow vsftpd daemon to change users into their $HOME directories. To do that update SELinux configuration using the command below.
[[email protected] ~]# setsebool -P ftp_home_dir on
And finally connect to the FTP server.
[[email protected] ~]# ftp 192.168.1.200
Connected to 192.168.1.200 (192.168.1.200).
220 Welcome to OSTECHNIX FTP service.
Name (192.168.1.200:root): ostechnix
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> pwd
257 "/home/ostechnix"
ftp>
Its working now. You can use your FTP server.

Connect to FTP server using Filezilla from Client:

Download and install Filezilla client software to any one of the client systems. Open the Filezilla client and enter the username and password which we have created earlier and click connect.
FileZilla_001

Connect to FTP server via browser from the client:

Open the browser and navigate to ftp://192.1168.1.200. Enter the username and password which we cretaed earlier.
If you want to browse ftp server using domain name(i.e ftp://ostechnix.com) instead of ip address, add the ftp server ip in the DNS server records. For more information to configure DNS server navigate to Setup DNS server in CentOS 6.3/RHEL 6.3/Scientific Linux 6.3.
Thats it. You can access your FTP server from any client now using Filezilla and as well as from your client web browser.
Have a good day!!!

Great tutorial, but you forgot to tell us to turn the firewall back on at the end 🙂 (Or add the FTP ports to it)

Srichakradhar Reddy Nagireddy March 11, 2014 - 7:06 pm

Can anyone just show how to add the FTP ports to the firewall and turn it on.?

Edit iptables file,

# vi /etc/sysconfig/iptables

Add the following line:

-A INPUT -m state –state NEW -m tcp -p tcp –dport 21 -j ACCEPT

Restart iptables.

# service iptables restart

Done..

Thank you… very helpful tutorial… Can i also change the port instead of default 21 or 22???

SK April 29, 2013 - 3:13 pm

Hi Gaurav!

$ vi vsftpd.conf

Find the following lines

listen_port=21

Change the port number whatever you want and restart the vsftpd service.

Hope it helps.

How can I have the banner displayed also for users coming in using a browser ? My Security Polilcy requires it, but seems that banner is only displayed when accessing FTP via CLI . Using banner only username/password is required, but then no banner is shown.. : /

DUDE, why did you leave the firewall disabled? That is a terrible idea.

THANK YOU SO MUCH! If I could, I would kiss you. This is by far one of the BEST tutorials I’ve come across in a very long time. I have spent the last 3 hour trying to setup vsftpd and log in remotely, but nearly all the tutorials on the web are ill illustrated and very confusing. Your tut got me up and running in 4 minutes.

One more thing, If I want to ftp over ssh, that is sftp to be more secure, how would I go about?

Thank you once again
