Allora, scusate la mia ignoranza con i server ftp, allora girando quà e là non sono riuscito a risolvere il mio problema.

Dunque il mio problema è il seguente: vorrei configurare proftpd per fare da server a dei siti internet, ho impostato l'autenticazione tramite mysql e pare che funzioni, ora vi posto l'attuale conf di proftpd:
#
# /etc/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes reload proftpd after modifications.
#

ServerName "Debian"
ServerType standalone
DeferWelcome off

allora nel db mysql ho sia l'utente ftp che ia, l'acesso funziona distinto per tutti, ora spiegatemi queste cosette:
1- è necessario esare il "tag" <Anonymous></Anonymous> oppure esiste un'altra sintassi per avere lo stesso risultato?
2-purtroppo non riesco a scrivere nella dir degli account ftp, come la risolvo?

spero che mi potete aiutare, in rete non ho trovato esempi chiarificatori.
Grazie
