FTP(S)

Upload verification files via FTP(S)

Description

This plugin uploads the validation challenge to a (secure) FTP server.

web.config

Optionally this plugin can place a web.config next to the validation file, to help IIS properly serve the response. There are many reasons why IIS can fail to properly serve the file. Some of them can be fixed this way. In interactive mode the program will ask you if you want to do this. In unattended mode you can request it using the command line. The web.config that will be copied lives in the root of the program directory with the name web_config.xml. You can modify it to fit your needs, e.g. for MVC sites you might need the following:

<configuration>
    <system.webServer>
        <staticContent>
            <clear/>
            <mimeMap fileExtension = ".*" mimeType="text/json" />
        </staticContent>
        <handlers>
            <clear />
            <add name="StaticFile" 
			path="*" 
			verb="*" 
			type="" 
			modules="StaticFileModule,
			         DefaultDocumentModule,
					 DirectoryListingModule" 
			scriptProcessor="" 
			resourceType="Either"
			requireAccess="Read" 
			allowPathInfo="false" 
			preCondition="" 
			responseBufferLimit="4194304" />
        </handlers>
    </system.webServer>
</configuration>

Or to disable URL Rewriting you might need to add this (in the beginning, right after <clear />).

<rule name="LetsEncrypt Rule" stopProcessing="true">
    <match url="^\.well-known.*$" />
    <action type="None" />
</rule>

Let us know if you could use a similar feature for uploading an .htaccess!

Microsoft TLS vs. GnuTLS

If you experience connection issues when running simple-acme on Windows while connecting to a Unix FTPS server, using the GnuTLS library instead of Microsofts native TLS might solve the problem. This page by the FluentFTP project explains the reasons behind and limitations of this method.

Using this requires:

• A change in settings.config, Validation.Ftp.UseGnuTls should be set to true.
• The pluggable x64 release of simple-acme (it is not available for x86 or ARM due to limitations of the upstream package, and also doesn’t work on the trimmed build)
• Download and extract the additonal build artifact gnutls.v2.3.0.33.x64.zip for the current release (or find older versions on GitHub).
