   At both Free Geek and the coffee shop this morning /etc/resolv.conf was
set by the local DHCP servers and showed the IP addresses for the two
nameservers they provided. I wrote that this was the case; the coffee shop
provided 8.8.8.8 and 8.8.4.4 that's why I used them. I am _not_ using the
default resolv.conf that's set up for ethernet on the LAN, but whatever
resolv.conf is set by the wifi servers at the two locales.
