> Is there a way to check if squids are talking to each other? The access.log of each proxy will contain entries for messages going to and from the sibling. On a basic setup like you have so far, expect to see SIBLING hit/miss codes sometimes. UDP_SIBLING_* are the ICP messages flowing between the siblings as they check whether the other has an object. TCP_SIBLING_HIT are the actual HTTP reply objects being fetched. Amos Hi Amos! I dont see anything inside of the access.log about the SIBLING. Could it be the log level somewhere? Or something is configured wrong? In fact I only see logs starting with TCP_(MISS/200, REFRESH_UNMODIFIED, IMS_HIT/304, MEM_HIT/200, TCP_HIT/200, etc...) Nothing with UDP_ What can be wrong? Tibby
