Failed SSHD Login Attempts (15,000 per day) - Is that a lot compared to your server?
The purpose of this thread is for everyone to follow the same methodology so we can create a future table, for the benefit of all, that shows how many failed login attempts (hacking) per day per server (and per minute) are happening.
This is not a thread on writing scripts or creating different methods to get the same data; nor it this a thread on how to prevent brute force logins; This thread has a a very simple (not elegant, not interesting) method that everyone can follow and by using the same very simple method, the results will be easy to compare, apples to apples, as follows:
Days Total (approx): 22
Is that a lot compared to your server?
Please post back your results using the same method:
Then take the totals days by comparing the dates in the head and tail, and divide that (the days) into the total number from the lastb | wc -l command and post back (just like I did above)
Thanks.
PS: If all replies use the same method, it will be easy to compare the results in a table or chart later. Please do not use any other method than the very simple one above.
Thanks!
If we get enough replies, I will do a video on the results later.

Hey all I'm having a big problem here. Someone is attempting an SSH to a destination host on which an account resides and locking the account.
