Hi, squid users. I am trying to make some proxies talk to each other, but something is wrong with my squid.conf files and I don't know what it is. I have in my network a "swarm" of sibling proxies and a single parent proxy. A client browser connects to a proxy from the swarm and it asks the others in the swarm for cache hits. If file is not served, the cache miss is treated by the parent proxy. I then proceed by running the following test: 1. Start squid in machine A; 2. Connect browser to squid in machine A; 2. Access a site to cache files; 3. Start squid in machine B; 4. Connect browser to squid in machine B; 5. Access the same site again in machine B I know that squid in machine A is caching files, because store.log tell me they are SWAPOUT'd as they arrive, but when I go through step 5, the access.log in machine B tells me that it is going directly through the parent proxy: 1179521182.776 213 <external ip address> TCP_MISS/304 460 GET <file URL> - FIRST_UP_PARENT/parent-proxy image/gif Right? Why does machine B go directly to the parent proxy if machine A has a copy of that file in the cache? The access.log in machine A tells me that the file is missing: 1179506674.109 0 <machine B ip address> UDP_MISS/000 70 ICP_QUERY <file URL> - NONE/- - And here is squid.conf for the siblings: ======================================== # Listen to port 3128 http_port 3128 # Listen to ICP too. icp_port 3130 # Parent proxy cache_peer parent-proxy parent 80 0 no-query login=PASS # Siblings # # (proxy-only is used to avoid duplication of the contents of other # sibling proxies.) cache_peer proxy-b sibling 3128 3130 proxy-only cache_peer proxy-c sibling 3128 3130 proxy-only cache_peer proxy-d sibling 3128 3130 proxy-only # (...) # Obligatory acl all src 0.0.0.0/0.0.0.0 # Clients authorized to use this proxy. acl localnet src 172.16.0.0/12 192.168.0.0/16 127.0.0.1 # Internal servers. acl internal-servers dstdomain .internal.com.br .local.com.br # Redundant, but this is just a test anyway. prefer_direct off # Access internal servers directly, but never the external servers. always_direct allow internal-servers never_direct allow !internal-servers # Allow clients to use this proxy. http_access allow all # Allow siblings to access this proxy. icp_access allow localnet # Log and debug. access_log /var/log/squid/access.log squid debug_options ALL,1 33,2 log_icp_queries on ========================================= So, please, what am I doing wrong? Any help is appreciated. ;) Cheers, Pedro. -- Pedro de Medeiros - Ciência da Computação - Universidade de Brasília Home Page: http://www.nonseq.net - Linux User No.: 234250
