Hello Everyone,

I really hope this is not against group policy etc.. however our network is
being hit
hard by a China IP for the past 6 months. Our systems our up to date,
passwordless
ssh etc.. but they're DOS attempts are getting more and more aggressive.
Tried to
contact their phone number to no success (not valid). Emails don't get any
response.
The IP is 218.77.79.43. Do we have any options?

If you don't want to spend more than 2 minutes on this, then move sshd to a
different (randomish) port. Sounds naive, but it's dirt cheap and really helps.
