An examination of my GL-AR300M log file indicates a large number of external login attempts like the following:
autopriv.warn dropbear (18080): Login attempt for nonexistent user from 15x.x.x.x:40380.
Has anyone comes across this before and what particular solution have you used to counteract these SSH attempts? Can a program (i.e. Fail2Ban) be used on the router as a solution?
