olá, gosto de desafios, por isso estou sempre testando coisas, montei um proxy, para testar meus conhecimentos, funcionou tudo numa boa, eu mesmo fui montando o squid.conf, mas o problema é que sempre que reinicio o sistema, tenho que da um "sudo /etc/init.d/squid stop" ai fica em wait, ai dou ctrl+c, e denovo "sudo /etc/init.d/squid stop", após dou um "sudo /etc/init.d/squid start" e tudo funciona numa boa, naofunciona com restart nem reconfigure. O problema 'e que se eu não fizer isso, a internet fica com "time out".
meu squid.conf

o que tem no arquivo "/etc/init.d/squid" ?

eu uso o rcsquid com o conteudo abaixo

ps: squid instalado via codigo fonte (./configure --prefix-/usr/local/squid)
-------------------------------- arquivo rcsquid
#!/bin/sh
### BEGIN INIT INFO
# Provides: rcsquid
# Required-Start: $network
# Required-Stop: $network
# Default-Start: 2 3 5
# Description: inicia o proxy squid 2.7
### END INIT INFO

case "$1" in
'start')
/usr/local/squid/bin/RunCache &
echo -e "squid iniciado..."
;;
'stop')
killall RunCache
/usr/local/squid/sbin/squid -k shutdown
echo -e "squid finalizado..."
;;
*)
echo "Usage: $0 { start | stop }"
;;
esac
exit 0

--------------------------------

Outra dica é limpar o arquivo messages
# echo >/var/log/messages

executar um dos comandos abaixo:
#squid -k reconfigure
#squid -k shutdow
#/etc/init.d/squid stop &

e verificar o arquivo messages novamente para ver os que ocorrerem
#cat /var/log/messages
