The data connection could not be established: ECONNREFUSED - Connection refused by server

See original GitHub issue

Using the test.js example & attempting khổng lồ connect to lớn the vps from Filezilla I am getting the response:

Error: The data connection could not be established: ECONNREFUSED - Connection refused by server

After the menu command is issued. On the vps it looks lượt thích this:

FTP command: LISTDirectory has 0 filesCurrently no data connection; expecting client khổng lồ connect to pasv vps shortly...What would be causing this?

What would be causing this?

My guess: firewall rules. Vì you see in the log which port was used for PASV? If not, limit the PASV port range to lớn very few ports (dunno if 1 is enough). Then try opening any kind of server (e.g. Netcat) on these port(s) and check whether you can connect there.

OK I think I found what was not working. I write it here lớn help other in my situation…

First, my configuration :

Windows 7 ProNode 4.4.4npm 4.1.2

First of all, I was using the test.js configuration example :

pasvPortRangeStart: 1025, pasvPortRangeEnd: 1050}Then I had to confirm that the pasv selected port was not in used by other system services. So using the command netstat -abn > d:ftpd-test-port.txt give me interesting result

WcesComm TCP 0.0.0.0:1025 0.0.0.0:0 LISTENING TCP 0.0.0.0:1026 0.0.0.0:0 LISTENING eventlog TCP 0.0.0.0:1027 0.0.0.0:0 LISTENINGA lot of conflicts, there is the ActiveSync (Windows CE Synchronization & Communication Manager), wininit.exe và IIS.

This is not mention in the readme but when looking at the source code, we can mix null lớn port range & this will let the OS choose a không tính phí port,

pasvPortRangeStart: null, pasvPortRangeEnd: null}Now this is working properly.

BUT, looking at the source code of ftpd there a demo loop until we get a không tính phí port but what I’m not sure lớn understand is : If the port choose by ftpd (in specifed range 1025-1050) was not không tính phí (EADDRINUSE) then the loop should try another one a so one until we get free one or we exhausted the range… so why I’m getting a kind of freeze (Currently no data connection; expecting client lớn connect to lớn pasv server shortly…) ? It is a ftpd bug ?
