Hi Guys, How can I test if cache peering is working between three sdquid proxies.The configuration for peering on three sibling squid proxies is as follows on sproxy1 ------------- cache_peer sproxy2.example.com sibling 8080 3130 proxy-only cache_peer sproxy3.example.com sibling 8080 3130 proxy-only icp_access allow sproxy2.example.com icp_access allow sproxy3.example.com icp_access deny all on sproxy2 ------------- cache_peer sproxy1.example.com sibling 8080 3130 proxy-only cache_peer sproxy3.example.com sibling 8080 3130 proxy-only icp_access allow sproxy1.example.com icp_access allow sproxy3.example.com icp_access deny all on sproxy3 ------------- cache_peer sproxy1.example.com sibling 8080 3130 proxy-only cache_peer sproxy2.example.com sibling 8080 3130 proxy-only icp_access allow sproxy1.example.com icp_access allow sproxy2.example.com icp_access deny all Note that these are RedHat Linux boxes running Squid-2.5-STABLE5.Can some please advise what is the best way to confirm if peering is working between siblings?I tried to run tcpdump src 3130 on either of three proxies, but got no output.
