When I say squid user, I reference to proxy user for 2.7 version. This is my output of squid processes: A) root 3617 1 0 Jun03 ? 00:00:00 /usr/sbin/squid -D -YC B) proxy 3621 3617 0 Jun03 ? 00:00:01 (squid) -D -YC C) proxy 3622 3621 0 Jun03 ? 00:00:00 (unlinkd) There are 3 processes, where A is the squid monitor. I'd like knowing if I can run only processes B+C, excluding A; if I remember right many years ago I had problems with monitor process because squid starting went loop. Monitor tried to start squid until 10 times. I'm also interesting to know how start squid without using monitor process (A). What do you think ? >I don't quite understand what you are meaning by "two processes". > It means only B+C >I'd also recommend getting rid of cache_effective_group and ensuring the > OS group privileges are correctly set for the squid user I have not to use "cache_effective_group" directive but what means "ensuring the OS group privileges are correctly set for the squid user" ? thanks -----Messaggio originale----- Da: Amos Jeffries [mailto:squid3@xxxxxxxxxxxxx] Inviato: Friday, June 05, 2009 5:33 AM A: Riccardo Castellani Oggetto: Re: R: Two squid processes can run as squid users ?!
