Description

I have a number of systems that have multiple loopback interfaces. Just installed 1.5.3 on one of them and facter gives the following errors on starting: Device “lo:1” does not exist. Device “lo:0” does not exist. Device “lo:0” does not exist. Device “lo:0” does not exist. Device “lo:1” does not exist. Device “lo:1” does not exist. Device “lo:0” does not exist. Device “lo:1” does not exist. Device “lo:1” does not exist. Device “lo:0” does not exist.

It does list these in the interfaces, ipaddress, netmask, & network, but not lo Looks like there is an filter for lo but not aliases for it.

Platform? OS? etc? Can you run with —debug and include output too thanks.

#2
Updated by snemetz - over 3 years ago

Found the problem in ip.rb

if interface != “lo” && interface != “lo0”

Can this be changed to

if interface ~= /lo[0:]?\d?/

or something a bit better without breaking anything on another OS?

This is our own dialect of CentOS 4. Nothing at the network layer should be different from CentOS 4.

Look like I spoke too soon. Editing that line probably needs to be done, but it does not clear up the error.

Short term, I’m going to look at adding a filter to not process any loopback interface.
