how do find all failed login attempts via ssh?..

Answer / vimal kumar k, technomenace.co

Failed ssh logs are either written in /var/log/messages, or
/var/log/secure (configurable in /etc/syslog.conf). I am
assuming that the failed login attempts are recorded in
/var/log/secure:

grep ' authentication failure' /var/log/secure | sed -e
's/^\(.*\)\(rhost.*\)$/\2/p' | tr -s " " | cut -f2 -d"=" |
cut -f1 -d" " | sort -n | uniq -c

Will show you the count, and the IP/hostname of machines
that tried to access the system via ssh
