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
          inet addr:192.168.5.90  Bcast:192.168.5.255

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.
