Hi , We are running Squid ver 2.5 STABLE5 on Red Hat. Our set up consists of all the departmental proxies(Novell & Squid) configured to use our proxy (super proxy) as parent and the departmental proxies can not go out to internet directly. There are three super proxies and are sibling to each other. Since we turned on sibling, we are getting a lot of the following message in the access.log and also looks like performance is not very good. 1) What is the minimum configuration needed in the super proxies to allow sibling each other and to act as a parent for the departmental proxies? 2) What is the cause of the following error message? 1153198439.920 322 192.168.6.143 TCP_MISS/200 13351 GET http://www.innovatoys.com/images/kablaster.jpg - TIMEOUT_DIRECT/204.10.70.167 image/jpeg 1153198440.198 501 192.168.6.143 TCP_MISS/404 688 GET http://www.innovatoys.com/images/fire.jpg - TIMEOUT_DIRECT/204.10.70.167 text/html 1153198440.409 95 192.168.6.143 TCP_MISS/200 4960 GET http://www.theage.com.au/entertainment/planner/planner.html - TIMEOUT_DIRECT/203.26.51.42 text/html 1153198440.499 3263 192.168.6.143 TCP_MISS/200 127451 GET http://www.myspace.com/undefined - TIMEOUT_DIRECT/63.208.226.42 text/html 1153198440.587 976 192.168.6.143 TCP_MISS/200 22807 GET http://www.innovatoys.com/images/zero-G.jpg - TIMEOUT_DIRECT/204.10.70.167 image/jpeg 1153198441.184 980 192.168.6.143 TCP_MISS/200 10501 GET http://www.innovatoys.com/images/micro.jpg - TIMEOUT_DIRECT/204.10.70.167 image/jpeg 1153198441.408 501 192.168.6.143 TCP_MISS/200 13386 GET http://www.innovatoys.com/images/skyliner.jpg - TIMEOUT_DIRECT/204.10.70.167 image/jpeg 1153198441.801 3586 192.168.6.143 TCP_MISS/200 39428 GET http://netmode.vietnamnet.vn/dataimages/200607/original/images1037973_3.jpg - Thanks
