Hello Squid world, I can't get siblings to talk to each other. Maybe there's some reason that they don't need to that I'm missing? Or I have it misconfigured. I have two squid caches. host1 has 75GB cache and host2 has a 40GB cache. in host1 I have: cache_peer host2 sibling 8888 3130 proxy-only and on host2: cache_peer host1 sibling 8888 3130 proxy-only I must be missing something obvious, the setup seems simple enough. Other settings in both: acl local src 192.168.0.0/255.255.0.0 icp_port 3130 icp_query_timeout 500 icp_access allow local icp_access deny all I don't find anything in access_log i.e. grep CACHE_DIGEST_HIT access_log Any ideas?
