Hi Eric, ipvsadm allows each real-server to have an upper and lower connection threshold, as described in the ipvsadm man page. Unfortunately this isn't always exposed by higher-level tools (to my shame I believe it is still missing from ipvsadm!). _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - [email protected] Send requests to [email protected] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
