Auto-Block SSH Intruder on Fedora7

From เมื่อถูก Brute-Force Attack ที่ sshd

Log in as root and type:

chmod 604 /var/log/secure yum -y install denyhosts service denyhosts start chkconfig denyhosts on

Then DenyHosts will do its job. No need for maintenance.

You can view the blocked IP at:

/etc/hosts.deny

Activity log file is here:

/var/log/secure

The configuration of denyhosts is here:

/etc/denyhosts.conf
