Hey you should check out fail2ban as well. Excellent little app that analysis the log for the corresponding demon using a regex (u can create custom ones too) and performs an action you choose including iptables, hosts.deny, etc.. You can easily adjust setting like 3 failed connections max per min, etc..
Works well for sshd, postfix, httpd, etc..also fires you an email when a attack is stopped Simple and very effective. Definitely worth checking out Aly Sent from my BlackBerry device on the Rogers Wireless Network -----Original Message----- From: Marian Marinov <m...@yuhu.biz> Sender: centos-boun...@centos.org Date: Mon, 4 Apr 2011 18:00:23 To: CentOS mailing list<centos@centos.org> Reply-To: CentOS mailing list <centos@centos.org> Subject: Re: [CentOS] sshd: Authentication Failures: 137 Time(s) _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
