Faillog: Reset authentication failures on Unix / Linux

Tag: Unix — berrisch @ 5:51 pm

Testing a lot on your servers can sometimes lead to the problem, that you receive this error message:
‘Received disconnect from Too many authentication failures for root’
or of course for other users, try faillog!

There are some options to view / reset the authentication failures for the given user(s)


This is the man page of this very useful command:
