Can incessant attacks on my wisp radio in Santa Cruz Mts be dropping service?
Daily I see in my Ubiquiti AirOS log multiple attacks on SSH port 22.
I also see periodic dropouts of the network, but they're not correlated
1:1 with those attacks so I had never put two and two together.However, yesterday I turned off access to SSH on my rooftop radio, and my signal for the past 24 hours has been super clean.
Here's the signal before I turned off access to port 22: (the red areas are pings that never returned, the blue is ping time0 (the x-axis is in reverse time, e.g., 3pm, 2pm, 1pm, etc. moving right)
Here is the signal AFTER I turned off access to port 22:
The difference is so astounding, that I wonder IF the little computer inside the radio was getting hammered by the attacks, which perhaps weren't even showing up on the log file???
Could that be?
