consigo iniciar o proxy usando squid -f /etc/squid/squid.conf
mas se eu tento ver o status "service squid status" me retorna a mensagem
squid (pid 10788) está rodando...
squid: ERROR: Could not read pid file
/var/run/squid.pid: (13) Permission denied

Kra, essa porta está sendo usada por outro aplicativo? Está bloqueada (firewall)? Para testar, faça no servidor:

# netstat -antp

Pra descobrir as portas utilizadas pelos processos, e:

# iptables -L

Pra descobrir se há alguma regra bloqueando essa porta.

Olá amigo do forum e aos googlandos de plantão,
estava tendo este mesmo problema aqui então resolvi pesquisar no google e cai
neste tópico, como ninguém postou uma solução vou postar a que eu encontrei, basta fazer o seguinte no terminal digite:
sudo chown "Nome do usuário ao qual se quer conceder a permissão de L/E"
/var -R

No meu caso estou usando o Ubuntu, na sua versão loga no terminal utilizando o user root e depois roda o comando.

Abraços!
