Cara Menutup port 22 untuk ssh

Hanya sekedar pemberitahuan, dan sebagai catatan buat saya sendiri khususnya..

saya copy saja langsung dari sumbernya : http://ubuntuforums.org/showthread.php?t=248342

sebagai berikut

basic a advice put to /etc/hosts.deny

Code:

sshd: ALL

this will block all connection to ssh

in hosts.allow you can put allowed IP

Code:

sshd: 195.168.65.*

you can alson use expresions like

Code:

sshd: ALL EXCEPT 195.168.26.56, 85.216.25.368

or you can try install this very good DenyHosts

script. this scripts reads info from /var/log/auth.log and automayicly add IP to hosts.deny. You can also use purge function to delete old blocking
