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.
