Subject: Arping loopback question.
Date: Thu, 30 Nov 2000 15:55:21 -0800 [thread overview]
Message-ID: <3A26E8E9.4B157465@e247inc.com> (raw)
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.
