[jira] Commented: (FTPSERVER-110) FTP returns 150 instead of
code/message for "port is disabled"
[ https://issues.apache.org/jira/browse/FTPSERVER-110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12537949 ]
Niklas Gustavsson commented on FTPSERVER-110:
---------------------------------------------
In this case, is the client sending a PASV before the PORT? Would it be possible to write a client test (like those in org.apache.ftpserver.clienttests) that reproduces this bug? Thanks!

> If using pasive mode and active mode is disabled the "PORT" command is answered with "510 port is disabled".
> However if you go on with the next command ("LIST"), then the FTPServer answers "150 ..." instead of "510 PORT command disabled before LIST") or
> some similiar descriptive error. Also the it is tried to open the active port and a 425 is sent:
