Very very intersting!!
The main correlation I've seen so far is with dhcpcd. Sometimes at my
work I get a 192. IP (which doesn't work), and other times I get a
133. IP (which is correct). In fact, sometimes dhcp is giving me an
IP address and resolv.conf related to a university I was visiting like
a month ago.
In other words, I know I have some networking problems, but I was
reluctant to imagine it was at all related to this login problem, even
though I had some basic empirical data on it.
Anyway, it happened again tonight, and it was resolved after I did
some of the same emerges as before, but I think that might be just
chance.
I look into the DNS stuff. Thanks for the sanity check!
