Una gran herramienta para tener logs es auditd y utilizar para ver los accesos por ssh.
Obs:
- Utilizo Debian Stretch de 64 bits.
Entramos a la terminal y tecleamos lo siguiente:
sudo apt update sudo apt install auditd sudo apt clean && sudo apt autoclean sudo systemctl start auditd
Usos:
sudo aureport -au -i | more
