[my transparent squid proxy isn't working]



try the following:

squid: make sure these elements are in your squid.conf
---cut---
httpd_accel_port 3128
httpd_accel_host virtual
httpd_accel_with_proxy on
httpd_accel_uses_host_header on
cache_peer      localhost       parent  8118    7       no-query default
header_access Via deny all
header_access From deny all
forwarded_for off
--end-cut---

privoxy: note that the cache_peer in squid config refers to SOCKS
proxy in privoxy config.
---cut---
listen-address  127.0.0.1:8118
forward-socks4a         /       127.0.0.1:9050  .
--end-cut---

tor: note that 9050 is the SOCKS proxy port for Tor.

iptables:
INTF=eth1 # internal network interface
ONTF=eth0 # external default route / public interface
---cut---
$IPTABLES -A FORWARD -i $INTIF -o $EXTIF -p tcp -m state --state
ESTABLISHED,RELATED -j ACCEPT
$IPTABLES -t nat -A PREROUTING -i $INTIF -p tcp --dport 80 -j REDIRECT --to 3128
---end-cut---


note that you'll want additional firewall / filter rules, and also
that DNS leaks may be present.  you will have to transparently proxy
DNS via dns-proxy-tor or equivalent to avoid this, and the following
filter rules can be used for transparent DNS proxy:
---cut---
$IPTABLES -t nat -A PREROUTING -i $INTIF -p udp --dport 53 -j REDIRECT
--to 65533
--end-cut--
where 65533 is where dns-proxy-tor is listening.

Uahu !I already had this but i love collaboration and thanks!contact me at skype gabx666 or visit the website i'm building at http://tor.gabrix.ath.cx ,please keep in touch ok ?
What i'm trying to is:
I have tor+privoxy on each lan machine behind the gateway , now , i want lan http requests to go first locally "torbuttoned" and than ,before togo in internet,beeing proxied again by the gateway squid-tor-privoxy ... am i crazy ?It's fun!
I have this iptables:


TOR=9001,9030,9031,9050,9090,9091
SQUID_PORT=3128


#$IPT -t nat -I PREROUTING -i $IF1 -p tcp -s 192.168.1.0/24 -m owner --uid-owner debian-tor --dport 80 -j DNAT --to 192.16$
$IPT -t nat -I PREROUTING -i $IF1 -p tcp -s 192.168.1.0/24 -m multiport --dports $TOR -j REDIRECT --to $SQUID_PORT



Http requests once they leave my lan machines they don't go to port 80 but a tor-socks port so i was trying to get them to go through my squid gateway port one way ( --uid-owner ) or the other.
GGG!


I corrected the iptables , i'm not using torbuttoned clients so direct to port , squid has default configuration, "just" added 'cache_peer localhost parent 8118 7 no-query default' and 'never_direct allow all'.


$IPT -t nat -I PREROUTING -i $IF1 -p tcp -s 192.168.1.0/24 --dport 80 -j REDIRECT --to 3128

Squid is doing my head in.

Is squid httpd accellerator for filtering incoming http requests
to inside lan's httpd servers ? Might be useless to consider it for clients
outgoing to the internet ?


SquidLogs:

It looks to me an ACL decision.I have clients netmask to 0.0.0.0 but it's just stdout for log files ... i will keep on trying different solutions ...

http_access allow all ... as start !

ciao !
