Connection Tab (Site Properties Dialog Box)

Use this tab to configure settings for maintaining connections and to set timeout intervals.

NOTE:For SFTP connections, the only setting available from this tab is Use IPV6.

Connection options

Use passive mode

When selected, the client sends a PASV command to communicate with the server in passive mode (sometimes called PASV mode). This initiates a separate data connection for directory listings and file transfers.

Use passive mode to minimize connection problems with firewalls.

If passive mode has been turned off and a directory listing does not display or you get an error "425 Can't open data connection," you should enable this setting.

IPV6 connections use EPSV.

Send keep alive every <n> seconds

Most FTP servers have an "idle time" value that specifies how long a user's FTP session can last when no activity is detected. When the user exceeds the time limit, the server connection is closed. This setting allows you to direct the Client to send a NOOP command to the server at timed intervals to prevent the server from closing the connection due to inactivity. When selected, specify the number of seconds to wait between transmissions of NOOP commands.

TCP port

Use the TCP port box to specify a non-standard TCP service port number or socket for FTP. The default value 21 is the standard service port for FTP.

Account

If your server requires an account name for file access, type it here. For case-sensitive servers, be sure to use the appropriate case.

When a connection is opened, if Account is filled in, the client automatically sends the account name to the server as the last logon step.

Timeouts in seconds

Connect

Select the maximum number of seconds to continue trying to establish an FTP server connection. Entering 0 (zero) in this box prevents the FTP Client from ever timing out on a connection attempt.

Session

Select the maximum number of seconds to wait for data packets being transferred to or from the host. If nothing is received within the period specified, a timeout error displays and the transfer is aborted; in this case, try the operation again. If you receive repeated timeout errors, increase the timeout value. Entering 0 (zero) in this box prevents the FTP Client from ever timing out when waiting for a response.

Other settings

Use IPV6

Select whether connections to the host use IPV6 (Internet Protocol version 6) or the older IPv4 protocol. By default, the client attempts to connect using IPv6, and uses IPv4 when IPv6 is not available. You may need to change this value to "Never" if you are having problems connecting to hosts on an IPv4 network from a client computer with IPv6 enabled.

Initial umask

Use this setting to specify an initial umask value to send to the server upon connection. You can use umask to modify the default permissions attributes set on newly created files. When you specify a umask, the client sends the following to the FTP server when you login, where nnnn is your specified umask value.

SITE umask nnnn

To find out if umask is a supported SITE command for your FTP server, enter this command at the FTP command line:

QUOTE help site

NOTE:

  • The umask set by the FTP client cannot be less restrictive than user permissions set on the server.

  • This option is not available if you have configured global upload attributes using Tools > Options > Attributes > Set default attributes on uploads.

  • This option is not available for SFTP connections.
