First of all, I installed the squid (SQUID 3.0.STABLE25) via yum as: su <root password> yum install squid* yum list squid cd /etc/squid ls The output of the last command ('ls') is: cachemgr.conf mime.conf squid.conf.default cachemgr.conf.default mime.conf.default squidGuard.conf errors msntauth.conf squidGuard.conf.rpmnew icons msntauth.conf.default mib.txt squid.conf I am using FC11. Squid not activated (only installed via yum). Installed squid only for the desktop single PC and is to be used for the single PC only. The main reasons to implement it is: 1. Speed improvement (or bandwidth improvement) 2. For security purpose so that intruders or transpassers cannot keep an eye. How could it be activated and implemented in FC11
