Hello, I have two machines with each two squid processes. I want that every process is querying the other three over htcp if it has a specified element in its cache. So this is my setting: -------------------------------- -------------------------------- | Proxyserver1: IP 192.168.1.1 | | Proxyserver2: IP 192.168.1.2 | -------------------------------- -------------------------------- | squid1: Port 8080 | | squid1: Port 8080 | | squid2: Port 8081 | | squid2: Port 8081 | --------------------- --------------------- This is the cache_peer configuration on Proxyserver1 process squid1: -- START config -- cache_peer 192.168.1.1 sibling 8081 4828 proxy-only htcp cache_peer 192.168.1.2 sibling 8080 4827 proxy-only htcp cache_peer 192.168.1.2 sibling 8081 4828 proxy-only htcp -- END config -- It's obvious, that cache_peer 192.168.1.2 sibling 8080 4827 proxy-only htcp and cache_peer 192.168.1.2 sibling 8081 4828 proxy-only htcp are different proxies, because they are using different ports. But squid can't be started: FATAL: ERROR: cache_peer 192.168.1.2 specified twice Squid Cache (Version 3.3.12): Terminated abnormally. How can I define two siblings on the same machine?
