Bon, on va dire que ton repertoire c'est /var/ftp .
Cree un compte systeme pour ca (pas obligatoire, mais plus sur) :
 
groupadd venerftp
useradd -g venerftp -d /dev/null -s /etc venerftp
 
Cree les repertoires :
 
mkdir -p /var/ftp/{upload,download}
chown 0:0 /var/ftp
chown venerftp:venerftp /var/ftp/*
chmod -R 755 /var/ftp
chmod 733 /var/ftp/upload
 
Lance le serveur ftp :
 
/usr/local/sbin/pure-ftpd -ABE -lpuredbetc/pureftpd.pdb
 
Pour creer un compte pour ginette :
 
pure-pw useradd ginette -m -d /var/ftp -u venerftp
 
Il te demande alors son mot de passe.
 
Pour effacer le compte de ginette :
 
pure-pw userdel ginette -m
 
Voila.
