Receiving Files

Since you have configured listens for incoming calls of the desired communication methods, you are able to receive files.

If there are files to be received from a Server contact and you connect to the contact (manually or automatically), the transfer of the files begins. You can observe the files transmission in the Status window.

Note: Find more information about the Status window and its options in the Transfer Statuses section.

Receiving files from Client, Web client, and Ad hoc contacts begins only if the contact initiates the connection.

You can see all received files from each of the contacts in the Received column of the Contacts window and in the Files window.

Note: Find more information about the Files window and its options in the Files Window section.

FTP Client Download Settings

The following setting is located in the MassTransit.cfg file:

%% DOWNLOAD_HIDDEN_FILES_VIA_FTP = FALSE

If this value is false, MassTransit will not download hidden files (meaning files starting with a '.') when connecting to FTP servers as an FTP client. By default, MassTransit will download all files, even files starting with a '.', EXCEPT for .DS_Store files, which are never downloaded.
You need to uncomment the value by deleting the '%%' before the setting can take effect.

Note: When you make changes to the MassTransit configuration files you need to restart the MassTranist services for the changes to take effect. The correct way to do this operation is to stop the MassTransit Engine service, restart the MassTransit Transporter and start the MassTransit Engine again.

MTWeb Transfers

Find detailed information about transferring files with MTWeb on the MTWeb page and in the Web Client User Guide.

Bandwidth Throttling

Note: Bandwidth throttling is available for TCP/IP, TCP/IP Secure, and UDT connections only on MassTransit HP servers.

Bandwidth throttling settings allow you to restrict the total bandwidth of the TCP/IP, TCP/IP Secure and UDT connections. By default, the total bandwidth is not restricted and you can use the whole capacity of your communication channel. The minimum bandwidth throttling can be 400 kBytes/minute.

To restrict the bandwidth throttling of the communication channel, follow these steps:

1. In the MassTransit Administrator application, open the Setup window by clicking on the Setup button from the Navigation Bar or by selecting the Setup... option from the Window main menu.
2. In the Setup window, select the Outgoing Calls tab.

   Note: The bandwith throttling settings apply to the inbound traffic as well.

3. Under the "MassTransit Protocol Bandwidth Throttling" area, check the Restrict bandwidth used by MassTransit Protocol connections checkbox.

   

4. Under the same section, set the total bandwidth that the TCP/IP, TCP/IP Secure and UDT connections will share.
5. Click on the OK button in the Setup window to save the changed settings.

Multi-streaming

Note: Multi-streaming is available on MassTransit HP servers only.

You can send files over multiple connections using different streams to the same Server contact. To use multi-streaming, set up two or more contacts for the same server; if one contact is sending files, you can make a connection to send files with the other contact. The files are sent simultaneously. Multi-streaming is available only for the following communication methods:

• TCP/IP
• TCP/IP Secure
• UDT.

  Note: For information about configuring communication methods, see Communications page.

Multi-streaming can be set while editing a Server contact that uses one of the communication methods listed above.

To configure multiple streams, follow the steps below:

1. In the MassTransit Administrator application, open the Contacts window by clicking on the Contacts button from the Navigation Bar or by selecting the Contacts option from the Window main menu.
2. Highlight an existing Server contact or click on the Add... button in order to add one.
3. In the Contact Information window that appears, select the Outgoing Calls tab.
4. Select TCP/IP, TCP/IP Secure or UDT, and then enter the server and port. Then click OK.
5. In the Multiple Stream Connection ID area that appears, enter a Stream ID to use for this contacts. Use a different one for each contact for a particular server connection and ensure that the same ID is set up on the other server.

Note: For information about configuring Server contacts, see Contacts page.

Performing Cyclic Redundancy Checks

Note: Cyclic redundancy checks are available on MassTransit HP and Enterprise servers only.

MassTransit performs Cyclic Redundancy Checks (CRC) for TCP/IP, TCP/IP Secure, and UDT transfers to validate the integrity of transferred files. While normally not necessary when transferring data over reliable protocols, CRC error checking allows MassTransit to detect file corruption problems and alert the contact. In some cases faulty network connections or hard disk drivers have been known to cause data corruption.
