Hello,

I am looking for documentation about the squid log, what does it mean TCP
MISS 503, instead of 200.
Is a problem of configuration in Squid or IPtables ?

thanks

My iptables rules :
iptables -A OUTPUT -o eth0 -m state --state NEW,ESTABLISHED -p tcp --dport
21 -j ACCEPT
iptables -A INPUT -i eth0 -m state --state ESTABLISHED -p tcp --sport 21 -j
ACCEPT
iptables -A OUTPUT -o eth0 -m state --state ESTABLISHED -p tcp --dport 20 -j
ACCEPT
iptables -A INPUT -i eth0 -m state --state ESTABLISHED,RELATED -p tcp
--sport 20 -j ACCEPT
iptables -A OUTPUT -o eth0 -m state --state NEW,ESTABLISHED -p tcp --dport
80 -j ACCEPT
iptables -A INPUT -i eth0 -m state --state ESTABLISHED -p tcp --sport 80 -j
ACCEPT
iptables -A OUTPUT -o eth0 -m state --state NEW,ESTABLISHED -p tcp --dport
443 -j ACCEPT
iptables -A INPUT -i eth0 -m state --state ESTABLISHED -p tcp --sport 443 -j
ACCEPT
iptables -A OUTPUT -o eth0 -m state --state NEW,ESTABLISHED -p tcp --dport
8443 -j ACCEPT
iptables -A INPUT -i eth0 -m state --state ESTABLISHED -p tcp --sport 8443
-j ACCEPT
iptables -A OUTPUT -o eth0 -m state --state ESTABLISHED,RELATED -p tcp
--sport 1024:65535 --dport 1024:65535 -j ACCEPT
iptables -A INPUT -i eth0 -m state --state ESTABLISHED -p tcp --sport
1024:65535 --dport 1024:65535 -j ACCEPT

eth0 is my internet interface

but any idea about the "503" means ?

How does your iptables interception rule look like? Did you try
intercepting tcp--->80 only?Seems you are doing for all (port 3128 for
any protocols ) which might be the problem!
