Perl POE DirWatcher

Can someone tell me if POE::Component::DirWatch works with an ftp directory .show me how you would watch a director开发者_Go百科y over ftp

1. No it won't.

2. FTP servers don't have any sort of notification method, so the only way you could do this would be to periodically run a LIST command on the remote directory and note any changes. Extra helpfully, there is no true standard for the format of the listing returned by LIST. Anyway, if you wanted to go this route, you could start with PoCo-Client-SimpleFTP and write a new component that emits events when files change on the remote server. Strong knowledge of FTP is recommended.
