BlockHosts

Not Rated
Description
Script to record how many times system services are being probed, using configurable pattern matching to recognize failed accesses (such as for "sshd" or "proftpd" or any service), and when a particular IP address exceeds a certain number of failed attempts, that IP address is blocked by using multiple techniques: using /etc/hosts.allow for services that support TCP_WRAPPERS, or by executing ip route commands to setup null-routing for that source host address, or by executing iptables commands to setup packet filtering to drop packets from a source host address.

Requires python version 2.3, and runs on Unix-like machines only.

Script is most suitable for home Linux users, who need to keep ssh/ftp ports or other services open, and need to block the script kiddies. With null-routing or packet filtering, any service can be protected, since those mechanisms block at the IP routing or packet filtering level, in this case, the only requirement is that there should be a way to detect failed accesses in some system log file.
