Hello, This is my setup. I have a transparent proxy server running SQUID2.4-STABLE2 on a FreeBSD box running 4.3-RELEASE. As any transparent proxy out there, HTTP requests are intercepted by our primary router and redirected to the FreeBSD box and the FreeBSD box hijacks it and makes the HTTP connection in behalf of the hijacked HTTP request. Everything is working just fine. But, just one observation from the FreeBSD box if you do a # netstat -an I see so many tcp socket connections in either FIN_WAIT_1, FIN_WAIT_2, or TIME_WAIT status. <cut> tcp4 0 0 199.172.146.99.80 202.58.248.20.3108 FIN_WAIT_1 tcp4 0 0 64.4.13.171.80 202.58.248.20.3106 FIN_WAIT_2 tcp4 0 0 206.49.81.19.24737 207.25.71.212.80 TIME_WAIT tcp4 0 0 64.38.209.154.80 202.58.248.20.3099 FIN_WAIT_2 tcp4 0 0 216.136.172.223.80 202.58.253.254.3894 TIME_WAIT tcp4 0 0 64.38.209.154.80 202.58.248.20.3095 FIN_WAIT_2 tcp4 0 0 216.115.106.35.80 202.58.248.20.3092 FIN_WAIT_2 tcp4 0 0 216.136.173.152.80 202.58.247.204.3265 TIME_WAIT tcp4 0 0 216.136.173.152.80 202.58.247.204.3263 TIME_WAIT tcp4 0 0 207.68.177.124.80 202.58.248.20.3090 FIN_WAIT_2 tcp4 0 0 64.58.76.229.80 202.58.247.211.1400 TIME_WAIT tcp4 0 0 209.85.3.8.80 202.58.248.20.3088 FIN_WAIT_2 <cut> Previously I have setup 2 other transparent proxy servers running FreeBSD 3.3-RELEASE and I see the same thing. Once its there, it stays there and each day its number grows. So what I do from time to time is to shutdown the FreeBSD box and boot it again just to remove these things and start over with a clean slate. I have also tried some tweaking in SQUID, most of them decreasing the timeout values like connect_timeout, read_timeout, request_timeout, pconn_timeout, and client_lifetime. Anyone out there who had this problem before ??? Thank you in advance. -- _________________________________________________________ Do You Yahoo!?
