I am trying to configure a bunch of SQUIDs as httpd_accelerators and in my first tests I could never get a HIT from a sibling... though ICP quesries are sent and UDP_HITS are recieved, SQUID always prefers to fetch from the origine server! I would always get TCP TIMEOUT code , untill I changes the minimum_direct_rtt to set it to zero. Now I always get TCP_MISS:DIRECT I enabled debuging of peer selection and it shows it clearly, please see the output bellow. First my config, then the debuging output: icp_hit_stale on icp_query_timeout 10000 minimum_direct_rtt 0 prefer_direct off dead_peer_timeout 3600 seconds http_port 80 httpd_accel_host 192.168.1.72 httpd_accel_port 80 httpd_accel_single_host on httpd_accel_uses_host_header on httpd_accel_with_proxy on cache_peer 192.168.1.224 sibling 3128 3130 allow-miss no-netdb-exchange cache_peer 192.168.1.223 sibling 3128 3130 allow-miss no-netdb-exchange cache_peer 192.168.1.222 sibling 3128 3130 allow-miss no-netdb-exchange cache_peer 192.168.1.221 sibling 3128 3130 allow-miss no-netdb-exchange icp_port 3130 debug_options 73,9 28,9 44,9 Debug: 2006/03/30 11:00:23| peerSelect: http://neo.your-site.com/data.4 2006/03/30 11:00:23| peerSelectFoo: 'GET neo.your-site.com' 2006/03/30 11:00:23| peerCheckNetdbDirect: MY RTT =3D 0 msec 2006/03/30 11:00:23| peerCheckNetdbDirect: minimum_direct_rtt =3D 0 msec 2006/03/30 11:00:23| peerCheckNetdbDirect: MY hops =3D 0 2006/03/30 11:00:23| peerCheckNetdbDirect: minimum_direct_hops =3D 4 2006/03/30 11:00:23| peerSelectFoo: direct =3D DIRECT_MAYBE 2006/03/30 11:00:23| peerSelectIcpPing: http://neo.your-site.com/data.4 2006/03/30 11:00:23| peerSelectIcpPing: counted 3 neighbors 2006/03/30 11:00:23| peerSelect: Doing ICP pings 2006/03/30 11:00:23| peerSelect: 3 ICP replies expected, RTT 10000 msec 2006/03/30 11:00:23| peerHandleIcpReply: ICP_HIT http://neo.your-site.com/d= ata.4 2006/03/30 11:00:23| peerSelectFoo: 'GET neo.your-site.com' 2006/03/30 11:00:23| peerCheckNetdbDirect: MY RTT =3D 0 msec 2006/03/30 11:00:23| peerCheckNetdbDirect: minimum_direct_rtt =3D 0 msec 2006/03/30 11:00:23| peerCheckNetdbDirect: MY hops =3D 0 2006/03/30 11:00:23| peerCheckNetdbDirect: minimum_direct_hops =3D 4 2006/03/30 11:00:23| peerSelect: SIBLING_HIT/192.168.1.224 2006/03/30 11:00:23| peerAddFwdServer: adding 192.168.1.224 SIBLING_HIT 2006/03/30 11:00:23| peerGetSomeParent: GET neo.your-site.com 2006/03/30 11:00:23| peerAddFwdServer: adding DIRECT DIRECT 2006/03/30 11:00:23| peerSelectCallback: http://neo.your-site.com/data.4 How can I get SQUID to use the peers if they have the object and only use origine if not? Thanks alot, this is driving me nutts, while Googling around I found my own post asking the acact same question right here on this list, almost two years ago!!! Mohamed~
