squid.pid owner

[tethys ocean]

Hello  All

We are running with squid proxy without ipfilter or pf.  Our squid block our
all outside connection. What am I do?  I wonder squid.pid's owner must be
root or squid user?

ie:proxy# ll /usr/local/squid/logs
total 52
-rw-r--r--  1 squid  squid  13479 Oct 17 12:10 access.log
-rw-r--r--  1 squid  squid  15482 Oct 17 12:12 cache.log
-rw-r--r--  1 root   squid      4 Oct 17 12:12 squid.pid
OR        -rw-r--r--  1 squid   squid      4 Oct 17 12:12 squid.pid
-rw-r--r--  1 squid  squid  19330 Oct 17 12:10 store.log

which is true?!

I think it is related with squid.conf file since I have to define some acl
accept rule?
