sudo works, but says 'unable to resolve host'
My machine is named brutus, and a while back I had some trouble with diagnosing my DSL connection. I don't know what I did but now when I sudo, it always says 'unable to resolve host brutus'. The sudo works, however. It seems like ever since then my xserver has been being flaky....adept notifier in particular. Any ideas what my hamfisted keyboard pounding might have messed up? If nothing else, the warning is annoying.
