Ошибка 500 ftp

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

RFC 2228 introduced the concept of protected replies to increase security over 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.

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.

500 Illegal PORT command + vsftpd + linux

Часто, если сервер находится за шлюзом и нам необходимо поднимать ftp, мы столкнемся с данной проблемой. Сторонний клиент из-за шлюза не сможет подключиться к нашему ftp-серверу, но с локальной сети никаких нестыковок не возникнет.

Проблема заключается в особенностях работы пассивного режима FTP.

Используя vsftpd нам необходимо предпринять несколько шагов для устранения данной неполадки.

• Внести изменения в vsftpd.conf (/etc/vsftpd.conf).

passv_enable=YES
passv_min_port=30000
passv_max_port=30100

• Перезагрузить vsftpd
• Открыть порты 30000-30100 на сервере
• Пробросить порты 30000-30100 на вашем коммутаторе в сторону сервера..

После этого из интернета ftp будет доступен в пассивном режиме.

Введение — зачем используются структуры? Все мы сильно любим структуры (идея, чуждая Java, не считая примитивных типов). Структуры, когда они не упакованы, зачастую, предоставляют прекрасную возможность обрабатывать динамические данные относительно небольшого размера. Размещение и освобождение типов данных в целом проще, чем размещение и освобождение ссылочных типов. Это связано тем, что структуры размещаются в стеке, либо встроены в содержащиеся типы и освобождаются, при очищении стека либо когда встроенные типы перераспределяются, в то время, как ссылочные типы размещаются в куче и очищаются сборщиком мусора (garbage-collected) Хм… Структуры не хотят наследоваться. Объектно-Ориентированное Программирование дает нам возможность делать много полезных вещей. И основной коцепт — это, конечно же, наследование. Многие из нас, когда либо, пытались наследовать структуру только для того, что бы понять, что C# не позволит нам этого сделать. Для примера рассмотрим код: /

Часто встречается необходимость выделить из строки выражения, которые находятся между простых скобок.

I am able to connect to server via ftp on port 21 after entering username/password in active mode. Also, I am able to run the commands like mkdir, pwd cd …. etc. But, when I try to run ls and get command, I am getting the below error:

ftp> get *.edr
500 Illegal PORT command.
ftp: bind: Address already in use
ftp> ls
500 Illegal PORT command.

I seek urgent help to resolve this.

  Hi,

  Something is wrong with ftp. Can you restart the ftp server?

  We are very wary of the ucodice domain. I can’t connect, which a strange state of affairs for a company whose facebook claims:

  «UcoDice IT solutions is your one stop solution for all your IT requirements.»

  Also strange that UcoDice is on twitter, facebook, nibbler, fanpop, have a train named after them in India, and still don’t bother to fill in their profile on ITtoolbox.

  The thing that your get and ls commands do, that the other commands you use do not do, is that they reverse-connect. That is, when the server runs an ls or get, it connects to your client through another port to send you the listing or file.

  So the problem is almost certainly your CLIENT being firewalled to stop incoming FTP connections, or not supporting this connection mode.

  There is no purpose in restarting the server-side FTP service. It ain’t broke.

  The 500 is a short error code from FTP — not a port number or anything more meaningful.

  The standard fix is to enter the command «pass» (passive) after you are connected. This should make the FTP server use your command channel for the returned data too. It might slow stuff down because using active can utilize multiple routes for simultaneous transfers.

  This is just your client ftp tool not being smart enough to support all ftp features.

  Just a minor correction. Passive FTP doesn’t re-use the command channel for data, it just reverses the direction the connection is initiated in. With active FTP, the server attempts to connect from port 20 to a high port on the client to send the data. With passive FTP, the client attempts to connect from a high port to a high port on the server to receive the data.

  The bind error could mean that port 20 on the server side is already in use by something else. Switching to passive mode will fix that, or you could shutdown whatever is already running on that port.

  Brian,

  I can’t figure that. The whole point of allocating known ports for connection is that they are handed off to a known unused port by inetd via ftpd, so the low port can be used multiple times for listening. It is easy to find a free high port on the local machine, to bind to.

  Neither the client nor the server should be permitted to connect direct to a high port number on the remote machine.
  .. It can have no idea whether the high port on the remote machine is already in use.
  .. There would be no way to determine what protocol to use on the incoming connection, or what process to bind it to.
  .. It would make firewalling impossible if it was allowed to happen.

  My definitive TCP/IP books are all in store, but it sounds very wrong to me.

  It doesn’t make sense, but it’s the way it works.

  You have to remember that the protocol was designed long before firewalls and NATs were in common use. This is a pretty good explanation:

  http:/ Opens a new window/slacksite.com/other/ftp.html

  In an active session, when you type «ls», or «get», your client picks a high port, and sends it to the server side using the «PORT» command. The server then tries to connect from port 20 back to your high port. Some smart firewalls intercept the port command and allow that specific traffic back in, some dumb ones just allow anything from port 20 in to high ports. NAT devices either can’t deal with active mode, or they intercept the PORT command, modify it outbound to the server, and setup a port mapping for the
  incoming request back to your original IP and port.

  In a passive session, the server picks the port, and your client connects to it. That’s much easier for firewalls and NAT devices because a lot just allow everything outbound.
