Squid on Ubuntu

simkin

I want to build a transparent squid proxy for home to play around with wccp configs. First step is to get a working squid proxy:

cd ~
wget http://www.squid-cache.org/Versions/v3/3.1/squid-3.1.4.tar.gz
tar zxf squid-3.1.4.tar.gz
cd squid-3.1.4

sudo ./configure –prefix=/usr –localstatedir=/var –libexecdir=/usr/lib/squid –srcdir=. –datadir=/usr/share/squid –sysconfdir=/etc/squid –with-logdir=/var/log –with-pidfile=/var/run/squid.pid –enable-wccp

make
make install

cd /etc/squid
sudo vi squid.conf

squid.conf:

http_port 3128
hierarchy_stoplist cgi-bin ?
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
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8
acl localnet src 10.0.0.0/8     # RFC 1918 possible internal network
acl localnet src 172.16.0.0/12  # RFC 1918 possible internal network
acl localnet src 192.168.0.0/16 # RFC 1918 possible internal network
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
http_access allow manager localhost
http_access deny manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost
http_access allow localnet
http_access deny all

start squid with: sudo squid -z

check it is running: ps -el | grep squid

Check the access log: cat /etc/access.log

Next step is getting WCCP configured:
