Hi I'm using a squid-2.5.10 and I've a problem with my users when try to connect on a FTP server that request a specific login and password. In to my squid.conf I've set the follow lines: ftp_user network@xxxxxxxxx ftp_passive on ie_refresh on In to my acl the ftp site aren't block. My PC is defined on the acl admin works fine. I've try change ftp_passive to off but don't resolve the problem. My ACL are: acl all src 0.0.0.0/0.0.0.0 acl arthis src XXX.XXX.XXX.XXX/255.0.0.0 acl private-network dst 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 acl admin src PC1 PC2 PC3 acl localhost src 127.0.0.1/255.255.255.255 acl dominigruppo dstdomain "/etc/squid/blacklists/dominigruppo" acl urlbloccate url_regex -i "/etc/squid/blacklists/urlbloccate" acl urlbloccate2 url_regex -i "/etc/squid/blacklists/urlbloccate2" acl domregexbloccati dstdom_regex -i "/etc/squid/blacklists/domregexbloccati" acl dstbloccati dst "/etc/squid/blacklists/dstbloccati" acl dominibloccati dstdomain "/etc/squid/blacklists/dominibloccati" acl dominiautorizzati dstdomain "/etc/squid/blacklists/dominiautorizzati" acl urlnocache url_regex -i "/etc/squid/blacklists/urlnocache" acl blacklists dstdom_regex -i "/etc/squid/blacklists/blacklists" acl passport-user src "/etc/squid/blacklists/passport-user" acl QUERY urlpath_regex -i cgi-bin .cgi acl METHOD method CONNECT POST acl ssl proto HTTPS http_access allow admin http_access allow dominigruppo http_access allow urlbloccate2 http_access deny dominibloccati !passport-user http_access allow dominiautorizzati http_access deny messanger !passport-user http_access deny blacklists http_access deny urlbloccate !passport-user http_access deny dstbloccati http_access deny domregexbloccati !passport-user http_access allow arthis http_access allow localhost http_access deny all no_cache deny QUERY no_cache deny urlnocache no_cache deny METHOD no_cache deny ssl Are a wrong configuration of mine acl?
