Mirror ftp in locale
Dovendo fare il mirror di un sito ftp ho trovato e testato un programma trovato in rete LFTP
Potete trovare una descrizione qui LFTP
Supporta IPV6 FTP, HTTP, FISH, SFTP, HTTPS and FTPS protocols.
Installazione su debian:
aptitude install lftp -y
Semplice script per il mirror del sito in locale:

Tra le varie opzioni:
-e commands #Execute given commands and don't exit.
--only-newer #download only newer files (-c won't work)
ftp:ssl-allow (boolean)
if true, try to negotiate SSL connection with FTP server for non-anonymous access.
Default is true. This and other SSL settings are only available if lftp was compiled
with an ssl/tls library.
mirror [OPTS] [source [target]]
Mirror specified source directory to local target directory. If the target directory ends
with a slash (except the root), the source base name is appended to target directory name.
Source and/or target can be URLs pointing to directories pointing to directories.
