Hi Eliezer, As recommended, I installed Squid V3.3.11. I followed the instructions provided at http://wiki.squid-cache.org/SquidFaq/CompilingSquid Downloaded the tar file, unzipped it and then did the following. # You will need the usual build chain yum install -y perl gcc autoconf automake make sudo wget # and some extra packages yum install libxml2-devel libcap-devel # to bootstrap and build from bzr needs also the packages yum install libtool-ltdl-devel The following ./configure options install Squid into the CentOS structure properly: --prefix=/usr --includedir=/usr/include --datadir=/usr/share --bindir=/usr/sbin --libexecdir=/usr/lib/squid --localstatedir=/var --sysconfdir=/etc/squid Now when I try to restart the squid service, it says unrecognized service.
