I have found the problem: I had switched to wicd for managing my wireless (I was using a hidden SSID and have not had luck with network manager). wicd wasn't configuring the loopback (lo) interface. I switched back to NM, which does configure lo, and all seems well (well, I haven't tested Retrospect, but the others are OK).
