Julien,
Make sure that all interfaces are covered if you have more than one: net.ipv4.conf.all.arp_ignore=1 net.ipv4.conf.eth0.arp_ignore=1 net.ipv4.conf.eth1.arp_ignore=1 net.ipv4.conf.all.arp_announce=2 net.ipv4.conf.eth0.arp_announce=2 net.ipv4.conf.eth1.arp_announce=2 You don't need the hidden stuff (don't think its in Ubuntu anyway.) also ipvsadm -Lnc will show a lot of SYN_RECV if you are getting ARP issues. 2008/9/29 Julien Cornuwel <[EMAIL PROTECTED]> > > Hi, > > I'm trying to set up load balancing with IPVS on two Apache webservers. > The loadbalancer and both apache servers are virtual machines running Ubuntu > 8.04 server on VMware ESX 3.5. > > If the platform has been idle for some time (like when I came back to work > this morning), I can point a browser to http://VIP and get pages from > server1 or server2 alternatively (I'm using rr during setup).
