Fail2Ban (version 0.7.5) 2006/12/07
|
|
|
|
|
=============================================================
|

|
|
Fail2Ban scans log files like /var/log/pwdfail and bans IP
|
|
|
|
|
that makes too many password failures. It updates firewall
|
|
|
|
|
rules to reject the IP address. These rules can be defined by
|
|
|
|
|
the user. Fail2Ban can read multiple log files such as sshd
|
|
|
|
|
or Apache web server ones.
|
|
|
|
|
|
|
|
|
|
