But still I get this error.....Code:425 Can't open data connection.Failed to retrieve directory listing.Yes, of course, because the listings and transfers do NOT use port 21. In the screenshot, the port offered was 49389 (192*256+237). So, in addition to the listening port, you need to define, open and forward a range of ports for Passive data connections (minimum recommended 100 ports). Please refer to the Network Configuration guide for details. Besides, in case you are behind a router and test from your own LAN, use the private LAN IP to connect. _________________### BEGIN SIGNATURE BLOCK ###No support requests per PM!

error code 425. There is a Wiki on Network Configuration that covers this information, however, it is written in such a ftp error 425 filezilla way that the “layman” may have difficulty understanding what’s going on—and it doesn’t show exactly how to fix the 425 error code—so this Wiki will give instructions on how to set up your specific router. https://forum.filezilla-project.org/viewtopic.php?t=24925 ”Abstract”[edit] This Wiki will go over the common technical reason(s) for error 425 being given after the FZS sends the 227 Passive command to the FTP client—regardless of what client is being used. This Wiki is written for the common user in a narrative tone—if a more in-depth technical Wiki is desired refer to the Network Configuration article. Narrative[edit] So, you've set up your FZS and it works for a https://wiki.filezilla-project.org/Setting_up_your_Router_to_Fix_the_%22425_code%22 local connection in your home, BUT you want to make your Local FTP Server accessible when you’re away—and you want to use encryption (SSL/TLS) to do so. You set up a Dynamic DNS (DynDNS) service to point to your FZS via your external IP address (don’t worry I’ll explain later in the Wiki). You’ve followed a how-to on setting up FZS to use SSL/TLS, but you've run into an issue—and after looking at the FZS Log you see the problem—right after the "227 Passive command" is given and acknowledged you see a 425 error. But even after summoning a Warlock, a Witch, and a Unicorn—you can’t fix it and wind up here reading this Wiki. The Problem[edit] More than likely the problem is that your FZS is requesting the FTP Client to use the Passive Ports defined in the FZS settings. And even though you’ve changed the settings in your Windows 7 or 8 Firewall you still can’t get your FTP Client to connect. Why? Well it’s complicated; the type of encryption that FZS uses doesn’t allow the router to “see” that you’d like to allow this communication, and thus the router blocks the data from being transferred. There are other programs you can use that would allo
iSeries SENDPASV; cannot open data connection; FTP Technote (troubleshooting) Problem(Abstract) Error 425 Cannot open data connection by running FTP communications Cause The data http://www-01.ibm.com/support/docview.wss?uid=swg21523306 connection (for a directory listing, upload, or download) was unable to be established. The most common solution: change the active/passive mode settings. The most common reason that this error occurs is a http://superuser.com/questions/847416/ftp-425-cant-open-data-connection-active-mode-does-not-work mis-configuration of the FTP server software itself, related to SSL connections and firewalls, in which the connection tries to establish itself on a bad IP address. You can set your FTP server ftp error up to use the Extended Passive Mode (EPSV) command. The EPSV command only sends the port and the IP address is inferred to be the same as the IP address of the control connection. Your server is configured to always use the same port for passive mode connections, or the client is configured to always use the same port for active mode connections, ftp error 425 although in this case usually the software in question should raise a different error first. In passive mode, the firewall in front of the FTP server does not have the correct ports open.So the server tells the client to connect to IP address 1.2.3.4 on port x, but the firewall does not allow incoming connections on port x. Most firewalls are smart enough to open up the port when it sees the PASV response. Vice versa for active mode and the firewall in front of the FTP client. Resolving the problem The OS/400 automatically sends in passive mode. To make the OS/400 run in active (non-passive) mode enter the OS/400 FTP client command SENDPASV, coded as a Tran=C in the session control script of the Communication profile. NOTE: Try also passive mode (depending on connection) SENDPASV 1 Historical Number SCI86400 Document information More support for: Sterling Gentran:Server for iSeries Software version: 3.5, 3.6 Operating system(s): IBM i Reference #: 1523306 Modified date: 2011-10-07 Site availability Site assistance Contact and feedback Need support?

By various means (explained at the bottom), I have been able to connect to this server remotely but only via Passive connections. I am not able to connect using Active mode - which the FileZilla client defaults to (in my case at least). The server is running Windows 8 and FileZilla Server (part of the XAMPP package) and is using the ports: 21 for listening 990 for implicit FTP over TLS 14147 for remote management 6000-7000 for Passive Mode These ports are opened in both the router's NAT and Windows Firewall. These are the settings for the server and these are the settings for the client under passive mode, fallback to active mode is selected also For obvious reasons, local connections work but remote connections do not. Worth mentioning - ftptest.net reports the connection as a SUCCESS, however I discovered that it uses PASV mode to connect to the server. I've put the log from this successful connection over at pastebin for reference. Again this is using Implicit FTP over TLS. Standard FTP connections do work using this website (and not through my own means of connecting), but I have them disabled within the server forcing SSL/TLS connections only. ftp share|improve this question asked Dec 2 '14 at 4:49 SteppingHat 183119 migrated from serverfault.com Dec 2 '14 at 5:12 This question came from our site for system and network administrators. PASV mode works better in NAT environments. Why are you displaying the passive mode settings for the server, but active mode settings for the client? –Paul Dec 2 '14 at 5:37 @Paul I was attempting to display all the settings actually.
