this is another history that i use squid. after install squid on my solaris box. i'm facing another problem. my cache.log always show warning like this, 2010/12/28 18:22:01| icmpSend: send: (96) Destination address required 2010/12/28 18:22:02| icmpSend: send: (96) Destination address required 2010/12/28 18:22:02| icmpSend: send: (96) Destination address required 2010/12/28 18:22:02| icmpSend: send: (96) Destination address required 2010/12/28 18:22:03| icmpSend: send: (96) Destination address required oh no, with this, i can not see more information in log.
