Transparent proxy with squid 2.6

I have upgraded my squid from 2.5 STABLE13 to 2.6 STABLE18. Transparent proxy is setup differently in this version. You need this directives in squid.conf (usually in /etc or /usr/local/etc or /usr/local/squid/etc, check with your distro).

acl our_networks src 192.168.2.0/24 127.0.0.1
http_access allow our_networks
http_port 192.168.2.1:3128 transparent
always_direct allow all

where 192.168.2.1 is your proxy server IP address.


If you have flushed your iptables, create new rule:

iptables -t nat -A PREROUTING -i  eth0 -p tcp –dport  80 -j REDIRECT –to-port 3128

where 3128 is the port where squid is running.

Squid - File size limit exceeded

Yesterday (15th Feb 2008) my squid died unexpectedly. I tried to restart it several times but to no avail. So I tried to see what went wrong by debugging and ran it in foreground. So,

squid -NCd3

N = put it in foreground
C = don't catch fatal signals
d = set debug level (3 is the level)

It threw a bunch of messages with the last line was File size limit exceeded. Just like this but I got no core dumped!. With no clue how to solve it, I recompiled squid (2.6-stable17) with extra parameters (with-max-fd=8192 and --with-large-files):

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-icmp --enable-kill-parent-hack --enable-ssl --enable-linux-netfilter --enable-large-cache-files --enable-follow-x-forwarded-for --with-large-files

It solved it. Shane reported here that this happens when file store.log is bigger that 2 GB. Disabling the use of store.log (or other relevant files for that matter) will get rid of this problem.
