Hi, I'm running squid in accelerator mode, and can't get a sibling cache working. The cache.log file doesn't say anything about siblings or ICP messages. It's almost as if the cache_peer line isn't being seen. I'm running 2.5.STABLE14. My config is included below. The sibling is configured exactly the same, with the exception of the cache_peer line pointing to this server. Has anyone seen this? http_port 80 httpd_accel_host 127.0.0.1 acl acceleratedHost dst 127.0.0.1/255.255.255.255 httpd_accel_port 82 acl acceleratedPort port 82 acl valid_domains dstdomain "/usr/local/squid/etc/valid_domains" acl myNet src 192.168.1.0/255.255.255.255 http_access allow acceleratedHost acceleratedPort http_access allow myNet http_access allow valid_domains cache_effective_user squid cache_effective_group squid httpd_accel_single_host on httpd_accel_with_proxy off httpd_accel_uses_host_header on redirect_rewrites_host_header off strip_query_terms off acl QUERY urlpath_regex cgi-bin no_cache deny QUERY cache_mem 2560 MB redirect_program /usr/local/squirm/bin/squirm redirect_children 100 max_open_disk_fds 5000 refresh_pattern ^http:.+/checkstatus/ 0 0% 0 refresh_pattern ^http:.+/statuscheck/ 0 0% 0 refresh_pattern ^http:.+/proximity[^/]*/ 0 0% 0 refresh_pattern ^http:.+/broadmatch[^/]*/ 0 0% 0 refresh_pattern . 34 100% 34 cache_peer 192.168.1.104 sibling 80 3130 hierarchy_stoplist cgi-bin ? minimum_object_size 1 Bytes cache_dir aufs /usr/local/squid/var/cache 10240 256 256 cache_store_log none auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours auth_param basic casesensitive off negative_ttl 10 seconds acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 563 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 563 # https, snews acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access deny all http_reply_access allow all icp_access allow all logfile_rotate 0 coredump_dir /usr/local/squid/var/cache
