Titolo: FTP con Squid

Ciao a tutti,
 
 
non riesco ad accedere a siti ftp passando attraverso Squid (2.7 su una 
Debian 6). La mia configurazione (prima di fare delle prove per l'FTP) è 
questa:
 
auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-
ntlmssp
auth_param ntlm children 5
auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid/passwd
auth_param basic children 5
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours
auth_param basic casesensitive off

Qualche idea?
 
 
Ciao,
  Void

 questa:
 
non ho mai provato, ma prova ad aggiungere la riga
 
acl Safe_ports port 20          # ftp-auth
 
Il protocollo ftp usa anche la porta 20, oltre alla più nota 21
 
Ciao,
Manuel

 Il protocollo ftp usa anche la porta 20, oltre alla più nota 21
 
La porta 20 viene aperta dal _server_ per spedire dati al _client_ nella cosiddetta modalità attiva.
E si chiama ftp-data, in effetti.

 acl Safe_ports port 20          # ftp-auth
 
In realtà funziona correttamente anche senza la porta 20: ho preso una 
cantonata io, scusate.
 
 
Ciao e grazie,
  Void
