SubjectArping loopback question.
Hello all.

Quick question here about an arping loopback adaptor. I've set lo to
noarp, and I've set /proc/sys/net/ipv4/conf/lo/hidden to 1. The
interface still arps for lo:0. I'm using Foundry server irons, and I
need to set the loopback interface in order for load balancing to work
properly.

After I clear the arp tables on my switches, and then ping the loopback,
I get the coresponding arp entry

sh arp
...
192.168.5.100 00:A0:CC:73:3F:4D
...


Here's the output from ifconfig.

eth1 Link encap:Ethernet HWaddr 00:A0:CC:73:3F:4D

I'm using 2.2.18pre22. eth1 is NetGear Gig-E adapter compiled into the
kernel. eth0 is an eepro100 compiled into the kernel.

Any ideas here?

Thanks in advance.
