<h2 id="list">LIST</h2>
<p>This command causes a list to be sent from the server to the passive DTP. If the pathname specifies a directory or other group of files, the server should transfer a list of files in the specified directory. If the pathname specifies a file then the server should send current information on the file. A null argument implies the user's current working or default directory. The data transfer is over the data connection. This command must be preceded by a PORT or PASV command.</p>

<p>The argument is a HOST-PORT specification for the data port to be used in data connection. There are defaults for both the user and server data ports, and under normal circumstances this command and its reply are not needed. If this command is used, the argument is the concatenation of a 32-bit internet host address and a 16-bit TCP port address. This address information is broken into 8-bit fields and the value of each field is transmitted as a decimal number (in character string representation). The fields are separated by commas. A port command would be:</p>
<p>PORT h1,h2,h3,h4,p1,p2</p>

<h1 id="ftpserver-and-port-21-on-linux">FtpServer and port 21 on Linux</h1>
<p>Under Linux only programs running as root is allowed to bind and listen to ports with port numbers below 1024. However, running a server which communicates with untrusted clients as root is not recommended for security reasons. The standard way to solve this problem in servers such as Apache HTTPD is to start the server as root and bind to the privileged port and then use the setuid C function to change the user ID of the current process. In Java there is no equivalent to the setuid C function in the standard API which means that one would have to use a native library to achieve the same, something which FtpServer doesn't support at the moment.</p>
<p>So, to have FtpServer listen on port 21 but still run it as a normal user one will have to look at other solutions such as using the firewall built into Linux. It turns out that this is really simple. Using the iptables command we can add a rule to the firewall that rewrites all TCP packets coming in on port 21 so that they are effectively forwarded to port 60021:</p>
