Hi all, I am a newbie squidish and Linux is also new to me. I am going to setup a squid transparent proxy for my small LAN. but, still I have many things to understand. I followed the installation guide of squid. but when I first launch squid it gives this error. and below is my squid.conf file that came with default. please, some one help me to go ahead. the error : [root@proxy ~]# /usr/local/squid/sbin/squid FATAL: getpwnam failed to find userid for effective user 'squid' Squid Cache (Version 2.5.STABLE10): Terminated abnormally.
