The JCR-FTP Server represents the standard eXo service, operates as an FTP server with an access to a content stored in JCR repositories in the form of nt:file/nt:folder nodes or their successors. The client of an executed Server can be any FTP client. The FTP server is supported by a standard configuration which can be changed as required.

FTP includes the following configuration parameters:

command-port
```
<value-param>

   <name>command-port</name>

   <value>21</value>

</value-param>
```
The value of the command channel port. The value '21' is set by default.
When you have already some FTP servers installed in your system, this parameter needs to be changed (for example, 2121) to avoid conflicts or if the port is protected.
data-min-port & data-max-port
```
<value-param>

   <name>data-min-port</name>

   <value>52000</value>

</value-param>
```
```
<value-param>

   <name>data-max-port</name>

   <value>53000</value>

</value-param>
```
These two parameters indicate the minimal and maximal values of the range of ports respectively, used by the server. The usage of the additional data channel is required by the FTP - protocol, which is used to transfer the file content and the categories list. This range of ports should be free from listening by other server-programs.
