You will have to recompile your kernel to be able to forward all traffic of your employees to squid, even if they don't use proxy in their browser. Compile it with Options IPFIREWALL_FORWARD Then install squid and add a rule to a firewall like this: fwd 192.168.1.1,3128 tcp from any to any dst-port 80 via xl0 Where 192.168.1.1 is a router, 3128 - squid port and xl0 is an outer interface. This will make all your network users go through squid and all their moves will be recorded. You will just need to install SARG, which will draw nice HTML tables with IPs and sites visited by them. I use it myself and it works just fine. I also use squid to deny downloading of avi and mpeg files, and also to deny some sites that are not work-related and should not be visited from office. Also Squid and SARG can count traffic, so you can see who spends how much, if you don' have an unlimited internet. -- С уважением, Бачило Дмитрий Руководитель отдела системной интаграции ООО "Компания Солинк" -- With Best Regards, Bachilo Dmitry Head of systems integration dept Solink Company Ltd. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Are there any decent proxy servers that I can put them on to see where they are going? Squid is a popular proxy server, although mod_proxy for Apache is another choice. However, you can analyze where someone is "going" on the net much more easily using a packet sniffer like tcpdump. However, this sort of issue is a management issue, not a technology problem. If the employee is getting their work done and meeting their deadlines, there probably isn't a problem worth pursuing. Otherwise, the issue is that this person isn't getting the work done, and whether they are surfing random pages or wasting time in some other fashion doesn't particularly matter -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
