   Not quite. The local LAN uses static IP addresses and defines DNS servers
in /etc/resolv.conf.

   All wireless access points (hotels, coffee shops, etc.) run dhcp and those
servers over-write /etc/resolv.conf, frequently leaving it empty. Therefore,
when plugged into the Ethernet cable here (with the static IP addresses) the
'network is unreachable.'

   I'll look for these.

   Actually, if I can grok how to add her to /etc/sudoers for the command
just adding 'cp /etc/resolv.conf.home /etc/resolv.conf' to her
~/.bash_logout would work quite well.
