Dexter is an FTP sitelist manager & verifier. It takes a list of FTP sites and spawns a collection of threads which go out and index all the files and directories on those FTP servers.

Process all the FTP sites you want in seconds. You can even point Dexter to a webpage that has a list of FTP links, and it will perform URL sucking and import all the sites from that page.

When the processing is complete, the indexes are written to an HTML file which can be viewed, edited, or posted to your website. You can configure the depth of the directory recursion as well as the maximum simultaneous threads, and PASV mode is supported.
