Public bug reported: I got onto my machine this morning and found networking broken. I traced it to the fact that denyhosts added 127.0.0.1 to the deny list. I couldn't find any events in the log that look like ssh attempts coming from localhost, but it still got added.
I would consider this an important bug because networking failed in a non-obvious way, which could cause data loss for network connections.
