Hi guys. I'm having trouble getting my direct routing LVS cluster up and
running. Per the instructions on
http://linuxvirtualserver.org/arp.html
and this message
http://marc.theaimsgroup.com/?l=linux-virtual-server&m=95533730908496&w=2
I issued the following commands on one of my real servers:
echo "1" >/proc/sys/net/ipv4/conf/all/hidden
echo "1" >/proc/sys/net/ipv4/conf/lo/hidden
ifconfig lo:0 206.66.49.220 mtu 150
where 206.66.49.220 is one of the public ip addresses that the cluster is
serving. Sadly, now the real server cannot communicate with the
206.66.49.0 network anymore. Actually, that's a lie - ICMP pings work
great, UDP name services don't work at all, telnet closes immediately.
Tcpdump seems to indicate that the real server is attempting to use the lo
interface to communicate with the 206.66.49.0 network, even though the
route command clearly shows that it should go over eth0:
[root@johnny /root]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
johnny-internal * 255.255.255.255 UH 0 0 0 eth1
206.66.49.219 * 255.255.255.255 UH 0 0 0 eth0
206.66.49.0 * 255.255.255.0 U 0 0 0 eth0
192.168.1.0 * 255.255.255.0 U 0 0 0 eth1
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 206.66.49.1 0.0.0.0 UG 0 0 0 eth0
I'm confused. Can someone point me in the right direction here? Thanks.
