Domain settings

On the Domain Limits & Settings > Settings pages, you can configure basic settings that affect performance, security, logo-in display, and network connectivity for the domain. To configure a setting, type the value you want in the appropriate area, and then click Save. This topic contains detailed information about the settings that you can configure.

Connection Settings

Block users who connect more than 'x' times within 'y' seconds for 'z' minutes

Also known as anti-hammering, enabling this option is a method of preventing brute force password guessing systems from using dictionary style attacks to locate a valid password for a user account. Using strong, complex passwords defeats most dictionary attacks. However, enabling this option ensures that Serv-U does not waste time processing connections from these illegitimate sources. When configuring this option, ensure that there is some room for legitimate users to correct an incorrect password before they are blocked.

When enabled, this option temporarily blocks (for the specified number of minutes) IP addresses that fail to successfully login (after the specified number of attempts within the specified number of seconds). IP addresses blocked in this way can be viewed in the appropriate IP access rules tab. A successful login resets the counter that is tracking login attempts.

Hide server information from SSH identity

When the connection has been established, the server sends identification information to the client. Normally, this information includes the server name and version number. Enable this option to prevent the information from being provided to the client.

Default Web Client

For the MFT Server, this enables you to specify whether the Web Client, Web Client Pro, FTP Voyager JV or File Sharing should be used by all HTTP clients by default. The third, default option is to prompt the users for the client they want to use instead. This option is also available at the group and user level.

Custom HTTP Logo, Login Page Text & Title Settings
HTTP Login Title Text (no HTML) Enter a text-only title to appear when a HTTP client logs into the file server.
Custom Logo Path

To use your own custom logo, create a 400 x 100 pixel graphic and enter or navigate to its location. An error message will be displayed if this criteria is not met.

To use the logo selected for the server level, select <<Inherit default value>> from the drop-down menu.

Use inherited default message Select to use the sever level message.
HTTP Login Page Text

Enter the text to be displayed on the HTTP login page.

This text can be HTML-formatted, including links, images, and standard formatting like italics, bold, underline, alignment and more.

HTTP Client Interface Background (CSS Only)

MFT only. Enter a CSS background style for the Web Client, File Sharing and FTP Voyager JV landing page. The format is:

color url('/%CUSTOM_HTML_DIR%/images/yourimage.png') repeat-type horizontal-alignment vertical-alignment.

The %CUSTOM_HTML_DIR% must be used in conjunction with the Custom HTML settings. Custom HTML must be enabled and a Custom HTML Container Directory must be specified.

The following examples provide a reference:

  • #0b16f8 url('/%CUSTOM_HTML_DIR%/images/Header01.png') no-repeat right top
  • #FFFFFF url('/%CUSTOM_HTML_DIR%/images/MyLogoTile.png') repeat-x left top
  • red (this example uses no image)
  • url('/%CUSTOM_HTML_DIR%/images/MyHeader.png') no-repeat center top (this example uses no custom color)
