Had to turn on SSH due to cisc0ninja's birthday and most of us being out of town. In that short amount of time, we had several bruteforce attempts despite the fact that we use keys in place of passwords.
Here are some of the IPs:
50.18.105.55
61.236.64.56
91.228.126.60
113.162.154.137
113.165.106.243
118.186.211.46
118.186.210.98
210.6.26.45
218.92.38.238
