Hi everyone, I am experiencing a strange issue that is more than likely a configuration error. I have a FreeBSD(6.1) box running Squid 2.6(9) connecting to a Cisco 7206VXR running IOS 12.4. Everything appears to be running well and traffic is being cached by the squid server but when I start the squid server my utilization on my internet connection goes from 10Mbps up to 13-15Mbps. As soon as I shut off squid the utilization returns to previous levels. Not much point in having a caching server if your internet usage increases. Any ideas what I have done wrong, what information would be helpful to diagnose. Thanks, Reid
Take a good look at the machines that are trying to use squid (from which both directions and location).
I can think of two immediate possibilities, which may or not be right. You are the one in a position to know and test.
1) You have a few(?) machines configured to use a proxy for updates or something. When the squid is off they can't do anything (low bandwidth) but when its on they do their thing.
2) Is there a rule at the FW capping web usage for users or their netblocks , but excluding the server you have squid on? Heavy users getting a free web access would explain it.
You will get a better idea yourself of whether its the above or something else by looking at the connections to-from squid when its active.
