Hi All I won't be able to make the April meeting which is a shame as I do look forward to having a chat to other Linux users. How are the workshop days and meetings etc funded? Has anyone rolled out a LVS server using ipvsadm, heartbeat, arptables and iptables? The problem At work we have 3 .NET web servers which LVS round robins connections and works fine and shows equal users on them. The application has a 30min session timeout, But LVS losses the session after 5 mins of non activity. This then breaks session and in most cases point user to another server and makes them re login I think it could be .NET cookie transaction string problem. So I am trying to use iptables and marking packets to try and make a sessions remain the 30mins through ipvsadm. I am going to try the L7 on Ultra Monkeys website tomorrow. I thought I would run it by everyone to see if there was any other good how to etc. Does anyone know of an dummies guide,URL's or a good "how to" to iptables. I would like to cover POSTROUTING,PREROUTING, MANGLE, NAT, INPUT, OUTPUT. when to use what is what im after. I have found the LARTC doc that Simon pointed me to very helpful but I can't always picture a means of getting the result I want. It's most likely because I have used microshaft windoze since 1984. So when using "route", "ip", "iptables" and "ip rules" etc should I be looking at these as different levels of apps or apps that have the same powers. If so would route be at a higher level than iptables or does iptables use say "route" or "ip" to create it's rules etc. Regards Sam -- No virus found in this outgoing message.
