Passive port ranges are not properly released
---------------------------------------------
Key: FTPSERVER-177
URL: https://issues.apache.org/jira/browse/FTPSERVER-177
Project: FtpServer
Issue Type: Bug
Affects Versions: 1.0
Reporter: Kevin Conaway
Priority: Critical
Attachments: FTPSERVER-177.patch
When using a range of passive ports, the passive ports are not appropriately
released. This leads to a deadlock after all the ports in the range have been
filled up.
I believe that this is because the QUIT command should be calling
session.getDataConnection().closeDataConnection(); which in turn calls
session.getListener().getDataConnectionConfiguration().releasePassivePort(<portNumber>);
In the attached patch, I've modified the
org.apache.ftpserver.clienttests.PasvTest testcase to use a 1-value range of
passive ports which exposes this issue. I've also added the
session.getDataConnection().closeDataConnection() to the QUIT command
