<system.ftpServer>

Overview

The <system.ftpServer> element specifies the global-level and URL-level configuration settings for FTP 7 in the ApplicationHost.config file, and contains configuration elements that define the settings that are used by the FTP service.

Note: Unlike settings that are found in the <system.webServer> element, settings in the <system.ftpServer> element cannot be delegated.

Compatibility

Version Notes
IIS 7.5 The <system.ftpServer> element ships as a feature of IIS 7.5.
IIS 7.0 The <system.ftpServer> element was introduced in FTP 7.0, which was a separate download for IIS 7.0.
IIS 6.0 The <system.ftpServer> element and its child elements replace the IIS 6.0 FTP settings that were located in the LM/MSFTPSVC metabase path.

Note: The FTP 7.0 and FTP 7.5 services shipped out-of-band for IIS 7.0, which required downloading and installing the modules from the following URL:

http://www.iis.net/expand/FTP

With Windows 7 and Windows Server 2008 R2, the FTP 7.5 service ships as a feature for IIS 7.5, so downloading the FTP service is no longer necessary.

Setup

To support FTP publishing for your Web server, you must install the FTP service. To do so, use the following steps.

IIS 7.5 for Windows Server 2008 R2

  1. On the taskbar, click Start, point to Administrative Tools, and then click Server Manager.
  2. In the Server Manager hierarchy pane, expand Roles, and then click Web Server (IIS).
  3. In the Web Server (IIS) pane, scroll to the Role Services section, and then click Add Role Services.
  4. On the Select Role Services page of the Add Role Services Wizard, expand FTP Server.
  5. Select FTP Service.

    Note: To support ASP.Membership authentication or IIS Manager authentication for the FTP service, you will also need to select FTP Extensibility.
  6. Click Next.
  7. On the Confirm Installation Selections page, click Install.
  8. On the Results page, click Close.

IIS 7.5 for Windows 7

  1. On the taskbar, click Start, and then click Control Panel.
  2. In Control Panel, click Programs and Features, and then click Turn Windows Features on or off.
  3. Expand Internet Information Services, and then FTP Server.
  4. Select FTP Service.

    Note: To support ASP.Membership authentication or IIS Manager authentication for the FTP service, you will also need to select FTP Extensibility.
  5. Click OK.

IIS 7.0 for Windows Server 2008 and Windows Vista

  1. Download the installation package from the following URL:
  2. Follow the instructions in the following walkthrough to install the FTP service:

How To

How to configure site-level or server-level logging for the FTP service

      • On the taskbar, click Start, and then click Control Panel.
      • Double-click Administrative Tools, and then double-click Internet Information Services (IIS) Manager.
  2. In the Connections pane, click the server name.
  3. In the Home pane, double-click the FTP Logging feature.
  4. In the One log file per drop-down list, choose one of the following options:
    • Choose Site to specify that each FTP site will write to individual log files.
    • Choose Server to specify a single log file for all of your FTP sites.
  5. In the Actions pane, click Apply.

Configuration Sample

The following sample illustrates several configuration settings in the global <system.ftpServer> element for a server. More specifically, the settings in this example demonstrate how to:

  • Enable FTP credential caching and specify a time-out of 10 minutes (600 seconds.)
  • Configure the low port as 5000 and the high port as 6000 for data channel communications.
  • Enable logging and specify that log files will be kept per-site, and that log files will be rotated daily by UTC time.
  • Specify a custom FTP provider and specify a custom parameter for that provider.
  • Specify global IP restrictions that allow FTP access from local host and deny access to the 169.254.0.0 to 169.254.255.255 block of IP addresses.
  • Configure request filtering with the following options:
    • Block FTP access to the _vti_bin virtual directory, which is used with the FrontPage Server Extensions.
    • Block several file types that are associated with executables.
    • Specify 100MB as the maximum file size.
  • Add a global authorization rule that allows access for the administrators group.
  • Specify that domain name syntax can be used for FTP virtual host names.

Sample Code

The following examples add two FTP authorization rules for the Default Web Site. The first rule allows read and write access for the administrators group, and the second rule denies read and write access for the guest account.

AppCmd.exe

appcmd.exe set config "Default Web Site" -section:system.ftpServer/security/authorization /+"[accessType='Allow',roles='administrators',permissions='Read, Write']" /commit:apphost

appcmd.exe set config "Default Web Site" -section:system.ftpServer/security/authorization /+"[accessType='Deny',users='guest',permissions='Read, Write']" /commit:apphost

Note: You must be sure to set the commit parameter to apphost when you use AppCmd.exe to configure these settings. This commits the configuration settings to the appropriate location section in the ApplicationHost.config file.

C#

using System;
using System.Text;
using Microsoft.Web.Administration;
internal static class Sample { private static void Main() { using (ServerManager serverManager = new ServerManager()) { Configuration config = serverManager.GetApplicationHostConfiguration(); ConfigurationSection authorizationSection = config.GetSection("system.ftpServer/security/authorization", "Default Web Site"); ConfigurationElementCollection authorizationCollection = authorizationSection.GetCollection(); ConfigurationElement addElement = authorizationCollection.CreateElement("add"); addElement["accessType"] = @"Allow"; addElement["roles"] = @"administrators"; addElement["permissions"] = @"Read, Write"; authorizationCollection.Add(addElement); ConfigurationElement addElement1 = authorizationCollection.CreateElement("add"); addElement1["accessType"] = @"Deny"; addElement1["users"] = @"guest"; addElement1["permissions"] = @"Read, Write"; authorizationCollection.Add(addElement1); serverManager.CommitChanges(); } } }

The following examples configure the <serverRuntime> element for an FTP server to allow domain name syntax for FTP virtual host names.

AppCmd.exe

appcmd.exe set config -section:system.ftpServer/serverRuntime /hostNameSupport.useDomainNameAsHostName:"True" /commit:apphost

Note: You must be sure to set the commit parameter to apphost when you use AppCmd.exe to configure these settings. This commits the configuration settings to the appropriate location section in the ApplicationHost.config file.

C#

using System;
using System.Text;
using Microsoft.Web.Administration;
internal static class Sample { private static void Main() { using (ServerManager serverManager = new ServerManager()) { Configuration config = serverManager.GetApplicationHostConfiguration(); ConfigurationSection serverRuntimeSection = config.GetSection("system.ftpServer/serverRuntime"); ConfigurationElement hostNameSupportElement = serverRuntimeSection.GetChildElement("hostNameSupport"); hostNameSupportElement["useDomainNameAsHostName"] = true; serverManager.CommitChanges(); } } }
