Hello, I am trying to run a two node LVS set-up. My VIP is 174.121.60.28 and my RIP is 174.121.60.50. I can ping the VIP from the RIP but am unable to ping the VIP from outside.
Ifconfig gives me this: eth0 Link encap:Ethernet HWaddr 00:26:B9:79:6E:C2 inet addr:174.121.60.50 Bcast:174.121.60.55 Mask:255.255.255.248 inet6 addr: fe80::226:b9ff:fe79:6ec2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1670618 errors:0 dropped:0 overruns:0 frame:0 TX packets:1521512 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:330044128 (314.7 MiB) TX bytes:353914009 (337.5 MiB) Interrupt:169 Memory:da000000-da012800 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1278 errors:0 dropped:0 overruns:0 frame:0 TX packets:1278 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1139484 (1.0 MiB) TX bytes:1139484 (1.0 MiB) ip addr show gives me this: 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:26:b9:79:6e:c2 brd ff:ff:ff:ff:ff:ff inet 174.121.60.50/29 brd 174.121.60.55 scope global eth0 inet 174.121.60.28/24 brd 127.255.255.255 scope global eth0 inet6 fe80::226:b9ff:fe79:6ec2/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 link/ether 00:26:b9:79:6e:c3 brd ff:ff:ff:ff:ff:ff 4: sit0: <NOARP> mtu 1480 qdisc noop link/sit 0.0.0.0 brd 0.0.0.0 Can anyone see what is wrong?

RedHat's network scripts will always send an arp broadcast first, which is exactly what you don't want. Instead, put something like this in your /etc/rc.local file: # solve the ARP problem echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore echo 1 > /proc/sys/net/ipv4/conf/eth0/arp_ignore echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce echo 2 > /proc/sys/net/ipv4/conf/eth0/arp_announce # Bring up loopback interface ifconfig lo:0 174.121.60.28 broadcast 174.121.60.28 netmask 0xffffffff up # Make sure traffic destined for the VIP gets handled by the loopback adapter route add -host 174.121.60.28 device lo:0 -- L�on _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-requ...@linuxvirtualserver.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
