Documentation forServ-U File Server

Connection

The Connection category contains many settings that allow you to configure how connections are created and maintained. Settings configured at the global level apply to all sites. Options pertaining to this page are described below:

Many options may be overridden within the Connection category within the Advanced Options of a site profile located within the Site Profile Manager.

Options pertaining to this page are described below:

General

After File Change Specify how files are handled when FTP Voyager detects an "open file" modification of a remote file.
Force PASV Mode Specify how FTP Voyager is supposed to handle the data connection for remote server connections. PASV Mode instructs the server to open another connection, and tells FTP Voyager where to connect. The PORT command instructs the server to initiate a connection TO the client. (For more information, please see the Help documentation within the Learn About Protocols section.)

Force PASV Mode has three options which are described below:
  • Automatic
    When a "passive" (a.k.a. PASV Mode) data connection fails for any reason, FTP Voyager automatically attempts a connection using the "active" mode (a.k.a. PORT Mode).
  • Enabled
    FTP Voyager establishes a data connection to the server using the PASV port that was returned from the server.
  • Disabled
    The server establishes a data connection with FTP Voyager with the information supplied within the "PORT" command that was sent to the server.
Connection Saver FTP Voyager normally uses multiple connections or logins for file transfers. By selecting this option, FTP Voyager uses only one connection. You would enable this option if your FTP Server allows you to login only once. If, while performing file transfers, you get a message that says you're already logged in or you login not accepted, enable this feature.
Remote Tab Reconnect Select "Yes" to open Remote Browser windows upon startup that were previously open when FTP Voyager was closed.

Connection Timings

Timeout The time during which FTP Voyager waits for a response from the server for a connection attempt. If a server does not respond to a connection request in this timeframe, FTP Voyager considers that the connection attempt has failed.
Retries The times that FTP Voyager retries a failed connection before giving up and informing the user of the failure.
Delay The number of seconds FTP Voyager waits between connection retry attempts.

Transfer Timeouts

Send Timeout The amount of time FTP Voyager will wait when trying to upload data to the server. After the time is exceeded, FTP Voyager will consider the transfer failed.
Receive Timeout The amount of time FTP Voyager will wait when trying to download data from the server. After the time is exceeded, FTP Voyager will consider the transfer failed.
Idle Timeout The amount of time FTP Voyager will wait until unused worker threads are cleaned up.

Keep Alive

Keep Alive Select this option if you want FTP Voyager to attempt to keep the FTP connection alive. This is done by occasionally asking the FTP server for its current directory.
Send After (seconds) Specify the amount of time between sending the "keep alive" command to the FTP Server.

File Transfer

Number of Workers Specify the number of worker threads that are actively processing the Transfer Queue Pane. Valid values range from 1 through 9.
Download File Tries If a download fails, FTP Voyager will try to resume the download automatically up the number specified here before discontinuing the transfer.
Upload File Tries If an upload fails, FTP Voyager will try to resume the upload automatically up the number specified here before discontinuing the transfer.
XCRC Checking When enabled, FTP Voyager uses an XCRC check to verify the transfer of a file. If a downloaded or uploaded file transfer results in the XCRC value not matching between FTP Voyager and the server, FTP Voyager attempts to upload or download the file again. FTP Voyager attempts this operation only when enabled and only when FTP Voyager identifies the server as supporting XCRC, usually through the results of the FEAT command.
Transfer Mode

Determine which mode with which files are transferred to the server. For more information, please see Auto ASCII Extensions within the Options dialog. The options are described below:

Binary Use this setting to transfer files without conversion. This mode is used when ASCII text files are not being transferred, or files are being transferred to and from compatible operating systems.
ASCII Use this mode to convert a file to a compatible ASCII mode on the destination. For example, [CR][LF] sequences are converted to [LF] sequences when transferring from a Windows operating system to a UNIX operating system.
Automatic ASCII Use this option to automatically change from the binary transfer mode to the ASCII transfer mode. This only applies to files that have a file extension defined within the Auto ASCII Extensions section of the Options dialog.

Transfer Rate

Limit Upload Rate Select "Yes" to enforce a transfer limit pertaining to uploads. This is useful to limit the maximum upload bandwidth used by a given site in situations where upstream bandwidth is limited and must be available for other applications and services.
Max. Upload Rate (KB/sec) Enter the maximum number of kilobytes that can be uploaded per second.
Limit Download Rate Select "Yes" to enforce a transfer limit pertaining to downloads. This is useful to limit the maximum download bandwidth used by a given site in situations where downstream bandwidth is limited and must be available for other applications and services.
Max. Download Rate (KB/sec) Enter the maximum number of kilobytes that can be downloaded per second.

Compression

Compression Mode FTP Voyager supports two compression levels - zlib compression, or no compression. By default, FTP Voyager automatically selects "zlib", but will disable compression if the remote server does not support it.
Compression Level The higher the compression level, the longer the data takes to encrypt but the less space it takes up in transit. FTP Voyager uses an optimized level of 6 by default.
