Description gp 1999-07-16 11:38:12 UTC
After changing a client from using DHCP to using a static IP
address using netcfg I had severe errors during the reboot
concerning neighbourhood table overflow errors. Traced it
down to being a badly configured loopback device. The file
/etc/sysconfig/network-scripts/ifcfg-lo was found to be
truncated. It looked like this:

ONBOOT=yes

whereas it should look like this:

BOOTPROTO=none  DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
BROADCAST=127.255.255.255
ONBOOT=yes
BOOTPROTO=none

It appears that netcfg caused this file corruption.

I don't see how netcfg could have done that.  If you can reproduce
it, I'd like to see the steps you took to do it so that I can make
an attempt to debug it here.  Thanks.
