Ftp 500 error

In this tutorial, we’re going to provide information regarding the error message 500 Unable to service PORT commands, including ways to fix it.

What Does the Error Mean?

The error message 500 Unable to service PORT commands usually occurs if you attempt to access a folder or upload a file to your server using an Active FTP data transfer mode.

By default, FTP may run in two modes – Active and Passive. Active mode is not currently supported on our Shared hosting platform, as it is considered less secure and reliable. So, any attempt to access a directory or manipulate data in active FTP mode will be blocked by the FTP server’s firewall.

How Can I Resolve this Problem?

In order to resolve the situation and connect to your server properly, you would need to enable Passive data transfer mode in your FTP software application.

Below you’ll find illustrated instructions on how to enable Passive mode in some of the most used FTP software applications (such as FileZilla, Cyberduck, CoffeeCup and Dreamweaver).

Configuring Passive Mode in FileZilla

You can follow these simple instructions to enable Passive Mode in FileZilla:

1. 1. Launch FileZilla.
   2. Open the Edit menu and click Settings….
   3. In the left pane, select FTP.
   4. Switch the Transfer Mode from Active to Passive (recommended).

Once you have made the necessary corrections, press OK and retry the connection.

Configuring Passive Mode in Cyberduck

To make your Cyberduck FTP account run in Passive mode:

1. 1. Start Cyberduck.
   2. Open the File menu and select Open Connection.
   3. Next, click on the More Options button.
   4. Change the Connect Mode setting from Default to Passive (PASV).

Press Connect and retry establishing an FTP connection.

Configuring Passive Mode in CoffeeCup

To enable Passive mode in CoffeeCup, perform the following actions:

1. 1. Launch CoffeeCup.
   2. Open the File menu and select Manage Servers.
   3. Next, click on the green plus icon.
   4. Mark the Passive Mode checkbox.

Press Connect, and then try to reconnect to your FTP server.

Configuring Passive Mode in Dreamweaver

You can configure Passive Mode in a Dreamweaver FTP client program in five easy steps:

1. 1. Start Dreamweaver.
   2. Open the Site menu and choose Manage Sites.
   3. Select the Servers tab and click on your existing AwardSpace FTP profile (account).
   4. Click More Options and select the checkbox Use Passive FTP.

Click Save, and then re-attempt to establish a connection.

Am I Able to Use Passive Mode in Windows FTP (FTP.exe)?

Unfortunately, the Microsoft built-in FTP tool does not support passive FTP data transfers. As a result, you won’t be able to establish an FTP connection to our server or transfer files via FTP.exe.

Therefore, we highly recommend that you use an FTP client program for migrating your website data. Information on how to use and configure an FTP client program can be found on our FTP Connection Settings page.

Hello Forum!

Being very new into FileZilla I’m hoping that someone here might be able to assist me getting my setup work smoothly.

A short background overview of my setup:

A dedicated Windows 2012R2 server located in our DMZ zone, our IT department has demanded that it’s being configured to use FTPS (tcp-990), and they’ve configured the firewall configuration to support this.

Ok, so far so good…

On the server I’ve installed and configured FileZilla Server 0.9.60 beta, in the “FTP over TLS settings, I’ve selected “Enable FTP over TLS support (FTPS), & “Disallow plain unencrypted FTP”, I’ve generated a certificate, and selected “Allow explicit FTP over TLS” – entered port 990 in the “Listen for FTP over TLS connections” and finally selected “Force PORT P to encrypt file transfers when using FTP over TLS” and “Require TLS session resumption on data connection when using PORT P”

Ok then… — and now explaining my problem… :

When using the Filezilla FTP client on a computer, I try to connect to my server – in the server log I can see that the client connect (= the firewall rules are working as the should I guess) but… — I can see in the log the “connected on port 990, sending welcome message” -> 220 “Welcome to my FTP server” -> 500 syntax error, command unrecognized

When using the build in FTP client in Ghisler “Total commander” I can connect with the exact same username and password as I’m using in Filezilla FTP client, however I do at the beginning see a “The certificate was not signed by a trusted party, continue anyway?” – if I select “Yes” the client connects, and everything is working (I can upload, download, edit, delete files on the FTP server)

The error I see in the Filezilla FTP client are the following :

Status: Connecting to xxx.xxx.xxx.xxx:990…
Status: Connection established, initializing TLS…
Error: GnuTLS error -15: An unexpected TLS packet was received.
Error: Could not connect to server

So… – I’m under the impression that the firewall properly is configured as it should be, and that the problem properly is located somewhere in my setup of the server client.

I’ve tried to follow all the “best practice” guides I could come across, however, no luck so far.

I would therefore be very thankful if anyone here have any suggestions!

Thanks in advance!

Kind regards

I am trying to create a script that uploads a .wav file after processing to a linux FTP server (utilizing vsftpd).

The script looks as follows:

@echo off

echo user anonymous> ftpcmd.dat
echo >> ftpcmd.dat
echo put C:UsersAnwenderDownloads%1 %1>> ftpcmd.dat
REM echo quit>> ftpcmd.dat
ftp -n -s:ftpcmd.dat 194.26.183.194
del ftpcmd.dat

My vsftpd.conf:

Range Purpose 1xx Positive Preliminary reply

The requested action is being initiated; expect another reply before proceeding with a new command. (The user-process sending another command before the completion reply would be in violation of protocol; but server-FTP processes should queue any commands that arrive while a preceding command is in progress.) This type of reply can be used to indicate that the command was accepted and the user-process may now pay attention to the data connections, for implementations where simultaneous monitoring is difficult. The server-FTP process may send at most, one 1xx reply per command.

2xx Positive Completion reply

The requested action has been successfully completed. A new request may be initiated.

3xx Positive Intermediate reply

The command has been accepted, but the requested action is being held in abeyance, pending receipt of further information. The user should send another command specifying this information. This reply is used in command sequence groups.

4xx Transient Negative Completion reply

The command was not accepted and the requested action did not take place, but the error condition is temporary and the action may be requested again. The user should return to the beginning of the command sequence, if any. It is difficult to assign a meaning to «transient», particularly when two distinct sites (Server- and User-processes) have to agree on the interpretation. Each reply in the 4xx category might have a slightly different time value, but the intent is that the user-process is encouraged to try again. A rule of thumb in determining if a reply fits into the 4xx or the 5xx (Permanent Negative) category is that replies are 4xx if the commands can be repeated without any change in command form or in properties of the User or Server (e.g., the command is spelled the same with the same arguments used; the user does not change his file access or user name; the server does not put up a new implementation.)

5xx Permanent Negative Completion reply

The command was not accepted and the requested action did not take place. The User-process is discouraged from repeating the exact request (in the same sequence). Even some «permanent» error conditions can be corrected, so the human user may want to direct his User-process to reinitiate the command sequence by direct action at some point in the future (e.g., after the spelling has been changed, or the user has altered his directory status.)

6xx Protected reply

The RFC 2228 introduced the concept of protected replies to increase security over the FTP communications. The 6xx replies are Base64 encoded protected messages that serves as responses to secure commands. When properly decoded, these replies fall into the above categories.

Code Explanation 100 Series The requested action is being initiated, expect another reply before proceeding with a new command. 110 Restart marker replay . In this case, the text is exact and not left to the particular implementation; it must read: MARK yyyy = mmmm where yyyy is User-process data stream marker, and mmmm server’s equivalent marker (note the spaces between markers and «=»). 120 Service ready in nnn minutes. 125 Data connection already open; transfer starting. 150 File status okay; about to open data connection. 200 Series The requested action has been successfully completed. 202 Command not implemented, superfluous at this site. 211 System status, or system help reply. 212 Directory status. 213 File status. 214 Help message. Explains how to use the server or the meaning of a particular non-standard command. This reply is useful only to the human user. 215 NAME system type. Where NAME is an official system name from the registry kept by IANA. 220 Service ready for new user. 221 Service closing control connection. 225 Data connection open; no transfer in progress. 226 Closing data connection. Requested file action successful (for example, file transfer or file abort). 227 Entering Passive Mode (h1,h2,h3,h4,p1,p2). 228 Entering Long Passive Mode (long address, port). 229 Entering Extended Passive Mode (|||port|). 230 User logged in, proceed. Logged out if appropriate. 231 User logged out; service terminated. 232 Logout command noted, will complete when transfer done. Alternatively: User logged in, authorized by security data exchange. 234 Specifies that the server accepts the authentication mechanism specified by the client, and no security data needs to be exchanged. 235 Specifies that the server accepts the security data given by the client, and no further security data needs to be exchanged. 250 Requested file action okay, completed. 257 «PATHNAME» created. 300 Series The command has been accepted, but the requested action is on hold, pending receipt of further information. 331 User name okay, need password. 332 Need account for login. 334 Specifies that the server accepts the authentication mechanism specified by the client, but some security data needs to be exchanged. 335 Specifies that the server accepts the security data given by the client, but further security data needs to be exchanged. 350 Requested file action pending further information 400 Series The command was not accepted and the requested action did not take place, but the error condition is temporary and the action may be requested again. 421 Service not available, closing control connection. This may be a reply to any command if the service knows it must shut down. 425 Can’t open data connection. 426 Connection closed; transfer aborted. 430 Invalid username or password 434 Requested host unavailable. 450 Requested file action not taken. 451 Requested action aborted. Local error in processing. 452 Requested action not taken. Insufficient storage space in system. File unavailable (e.g., file busy). 500 Series Syntax error, command unrecognized and the requested action did not take place. This may include errors such as command line too long. 501 Syntax error in parameters or arguments. 502 Command not implemented. 503 Bad sequence of commands. 504 Command not implemented for that parameter. 530 Not logged in. 532 Need account for storing files. 534 Request denied for policy reasons. 550 Requested action not taken. File unavailable (e.g., file not found, no access). 551 Requested action aborted. Page type unknown. 552 Requested file action aborted. Exceeded storage allocation (for current directory or dataset). 553 Requested action not taken. File name not allowed. 600 Series Replies regarding confidentiality and integrity 631 Integrity protected reply. 632 Confidentiality and integrity protected reply. 633 Confidentiality protected reply. 10000 Series Common Winsock Error Codes^[2] (These are not FTP return codes) 10054 Connection reset by peer. The connection was forcibly closed by the remote host. 10060 Cannot connect to remote server. 10061 Cannot connect to remote server. The connection is actively refused by the server. 10065 No route to host / DNS cannot be resolved. 10066 Directory not empty. 10068 Too many users, server is full.
