vsftpd is generally considered the most secure and fastest FTP server for UNIX-like systems. vsftpd supports chroot mode and allows you to control who can access (and not access) the ftp server.

vsftpd lives at https://security.appspot.com/vsftpd.html

The docs are included with the software install and also online at https://security.appspot.com/vsftpd.html#docs

The installed docs on Redhat-like systems are usually stored in /usr/share/doc/vsftpd-n.n.n.

===Configure===

Edit configuration to allow passive FTP:

RHEL 6 and 7 it is located in /etc/vsftpd/vsftpd.conf

Recommended settings:

Be sure to comment out "pasv_address" in the cloud like AWS since the instance IP address may change over time.

<pre>
pasv_enable=YES
pasv_min_port=40000
pasv_max_port=41000
port_enable=YES
#pasv_address=<IP Address>
</pre>

===Logging===

Two kinds of log files from vsftpd: transfers (xferlog) and ftp operations (log_ftp_protocol).

By default vsftpd uses

<pre>
xferlog_std_format=YES
</pre>

for logging. This will show all files moving through the ftp server, but if you want to view all the activity, including FTP connections and commands you need to set add

<pre>
log_ftp_protocol=YES.
</pre>

The problem is that you have to choose between one or the other. This verbose logging, logs everything which you may want when troubleshooting issues.

Edit vsftpd.conf

Recommended settings:

<pre>
syslog_enable=NO
vsftpd_log_file=/var/log/vsftpd.log
dual_log_enable=YES
log_ftp_protocol=YES
xferlog_std_format=NO
</pre>

===Operations===

To enable vsftpd to always start at boot:

<pre>
$ sudo chkconfig vsftpd on
</pre>

To turn on vsftpd now:

<pre>
$ sudo service vsftpd on
</pre>
