Roberto,
Well, well, well ... are you trying to get the IP packets confused with
your setup? :)
Wasn't "trying" to. Our hosting provider gave us 3 machines with 10
IP's each. According to them, all three machines are plugged into the
same physical switch. They are also the ones who setup all the original
networking parameters below.
From what I've seen, you seem to "own" a /24 class
--> 72.52.166.0/24. You might either want to:
For the most part, yes. I think there are 2 blocks in there that we
don't have: .66 - .128 and .142 - .254 I'm sure other customers of
theirs have those IPs.
Director: /etc/sysconfig/network-scripts/ifcfg-eth1 (and eth1-range0)
IPADDR=74.52.166.34
GATEWAY=74.52.166.33
NETMASK=255.255.255.240
IPADDR_START=74.52.166.35
IPADDR_END=74.52.166.45
GATEWAY=74.52.166.33
NETMASK=255.255.255.240
Slave #1: /etc/sysconfig/network-scripts/ifcfg-eth1 (and eth1-range0)
IPADDR=74.52.166.50
GATEWAY=74.52.166.49
NETMASK=255.255.255.240
IPADDR_START=74.52.166.51
IPADDR_END=74.52.166.61
GATEWAY=74.52.166.49
NETMASK=255.255.255.240
NO_ALIASROUTING=yes
Slave #2: /etc/sysconfig/network-scripts/ifcfg-eth1 (and eth1-range0)
IPADDR=74.52.166.130
GATEWAY=74.52.166.129
NETMASK=255.255.255.240
IPADDR_START=74.52.166.131
IPADDR_END=74.52.166.141
GATEWAY=74.52.166.129
NETMASK=255.255.255.240
NO_ALIASROUTING=yes
a) Set your netmasks for the the RIP to /24 or
b) Put your RIPs inside the same scope for all servers
So basically for IP-DR, all servers need to use the same GW on the same
switch? I'm guessing our hosting provider has the switch we are on
subnetted?
I hope this will work for you.
I see some light. Check this:
Director:
11:31:55.232013 IP 70.241.143.240.2366 > 74.52.166.35.telnet: S

11:32:04.254652 IP 70.241.143.240.2366 > 74.52.166.35.telnet: S
1094534970:1094534970(0) win 65535 <mss 1452,nop,nop,sackOK>
Slave #1:
11:31:52.930429 IP 70.241.143.240.2366 > 74.52.166.35.telnet: S
1094534970:1094534970(0) win 65535 <mss 1452,nop,nop,sackOK>
11:31:55.919545 IP 70.241.143.240.2366 > 74.52.166.35.telnet: S
1094534970:1094534970(0) win 65535 <mss 1452,nop,nop,sackOK>
11:32:01.953014 IP 70.241.143.240.2366 > 74.52.166.35.telnet: S
1094534970:1094534970(0) win 65535 <mss 1452,nop,nop,sackOK>
So now at least Slave #1 is getting the packets but I never got a
response back.
If I can't get my hosting company to put me on 1 subnet, should I revert
back to my original IP config and use IP-TUN instead? We discussed this
load balancing thing in a meeting yesterday and someone thought it would
be good to put one of our other machines with another provider on as
'fallback'. That would require using TUN wouldn't it?
Thanks,
Matthew
