Hi everyone, |
2 |
|

I am trying to setup some virtual IP's on a couple of servers and keep |
4 |
running into trouble with ARP responses. What I need to do is apply an |
5 |
ip alias to the loopback interface and disable arp responses on this |
6 |
interface. I have done this a couple of different ways but with the same |
7 |
result...doesn't work =/ |
8 |
|
9 |
here is what I have done: |
10 |
# ifconfig lo:1 10.10.10.116 netmask 255.255.255.255 |
11 |
# ifconfig lo:1 -arp |
12 |
|
13 |
When that didn;t work I tried the iproute2 path and did: |
14 |
# ip link set lo:1 arp off |
15 |
# ifconfig lo:1 |
16 |
lo:1 Link encap:Local Loopback |
17 |
inet addr:10.1.10.116 Mask:255.255.255.255 |
18 |
UP LOOPBACK RUNNING NOARP MTU:16436 Metric:1 |
19 |
|
20 |
Everything appears to be set right, but it is still responding to arp |
21 |
requests: |
22 |
# tcpdump -n | grep arp |
23 |
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode |
24 |
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes |
25 |
21:25:18.686611 arp who-has 10.1.10.116 tell 10.1.10.29 |
26 |
21:25:18.686647 arp reply 10.1.10.116 is-at 00:02:b3:e9:41:3f |
27 |
|
28 |

This really can't be that difficult of a task, but I have to be doing |
30 |
something wrong here. Any suggestions would be greatly appreciated. |
