A/UX 1.1: Solution for "loop:bad value" Error

A user gets the message

"loop:bad value"

before the Ethernet messages on A/UX startup. All Ethernet communications work well. Is this message
related to Ethernet, or something else?
This error message comes from the startup script BNET in /etc/startup.d. It can be caused by an incorrect entry in the /etc/hosts file for the loop address. The line for the loop address should look like this:

127.0.0.1 loop loo lo localhost Software_Loopback
