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.
