Salve a tutti ragazzi, questo è il mio primo post su questo forum. Scrivo perchè questo problema mi sta praticamente tormentando.
Il mio obiettivo è quello di creare un server ftp con utenti virtuali (indipendenti da quelli di sistema). Ho installato dal repository proftpd-mysql visto che questo server ftp permette l'autenticazione basandosi su un DB MySQL. A tale scopo ho creato un nuovo Database denominato proftpd in cui è presente l'unica tabella denominata users. La struttura di tale tabella è la seguente: UserId,Passwd,UID,GID,homedir,shell ed in essa è presente un solo utente rappresentato dai seguenti campi:
utente1 'sua password cifrata' 501, 65534, /home/ftp/, /bin/false
Dopo aver creato il database ho configurato il file /etc/proftpd/proftpd.conf nel seguente modo
Se tento di instaurare una connessione, sia sul server stesso (ftp localhost) che da un altro host della rete ottengo il seguente errore:Codice:# # /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file. # To really apply changes reload proftpd after modifications. # # Includes DSO modules Include /etc/proftpd/modules.conf # Set off to disable IPv6 support which is annoying on IPv4 only boxes.
