Hi, 1) HTTPS Interception I try to setup https transparent configuration with squid 3.1.20 The traffic was correctly forwarded to the proxy port 3129 via WCCP (Cisco ASA GW) , but the proxy doesn't use ssl connection to join the final server but a clear http connection with port 80 The flow client --> squid proxy use correctly ssl with the squid's certificate Any idea why the squid don't use a https connection to join the final server ? 2) FTP Interception If I understand correctly, squid can handle FTP transparent use with browser's use (FTP native client not suppported) I have configured only WCCP stuff, nothing about FTP on squid and I can see the 3-way handshake was established correctly between the client and the proxy, but after that nothing... If I want to use a native ftp client, anyone can suggest me a good ftp transparent proxy ( I see frox or ftp-proxy but theses softwares doesn't seem maintained or have a recent stable version) Many thanks for any info squid.conf: # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl localnet src 192.168.0.0/16 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT # # Recommended minimum Access Permission configuration: # # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports # We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user #http_access deny to_localhost # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # # Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed http_access allow localnet http_access allow localhost # And finally deny all other access to this proxy http_access deny all # Squid normally listens to port 3128 # Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs /var/spool/squid 100 16 256 # Leave coredumps in the first cache dir coredump_dir /var/spool/squid # Add any of your own refresh_pattern entries above these. refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 cache_access_log /var/log/squid/access.log cache_store_log none shutdown_lifetime 1 second icp_port 0 htcp_port 0 icp_access deny all htcp_access deny all forwarded_for off request_header_access Allow allow all request_header_access Authorization allow all request_header_access WWW-Authenticate allow all request_header_access Proxy-Authorization allow all request_header_access Proxy-Authenticate allow all request_header_access Cache-Control allow all request_header_access Content-Encoding allow all request_header_access Content-Length allow all request_header_access Content-Type allow all request_header_access Date allow all request_header_access Expires allow all request_header_access Host allow all request_header_access If-Modified-Since allow all request_header_access Last-Modified allow all request_header_access Location allow all request_header_access Pragma allow all request_header_access Accept allow all request_header_access Accept-Charset allow all request_header_access Accept-Encoding allow all request_header_access Accept-Language allow all request_header_access Content-Language allow all request_header_access Mime-Version allow all request_header_access Retry-After allow all request_header_access Title allow all request_header_access Connection allow all request_header_access Proxy-Connection allow all request_header_access User-Agent allow all request_header_access Cookie allow all request_header_access All deny all visible_hostname localhost maximum_object_size 4096 KB minimum_object_size 1 KB dns_nameservers 192.168.0.100 client_lifetime 360 minutes pconn_timeout 360 minutes wccp2_router 10.10.10.250 wccp2_forwarding_method gre wccp2_return_method gre wccp2_service standard 0 password=toto wccp2_service dynamic 70 password=toto wccp2_service_info 70 protocol=tcp flags=dst_ip_hash priority=240 ports=443 wccp2_service dynamic 60 password=toto wccp2_service_info 60 protocol=tcp flags=dst_ip_hash priority=240 ports=20,21 # DEBUG WCCP #debug_options 80,3 http_port 3128 transparent https_port 3129 transparent cert=/etc/pki/tls/certs/cert ssl-bump always_direct allow all ssl_bump allow all
