Using iptables to rate-limit incoming connections

Post date: December 16, 2005, 22:12 Category: Network Views: 4163 Comments
Tutorial quote: There are times when you have to allow arbitary incoming connections, when you are travelling for example.

In these situations you can open up your system to allow incoming connections and be the target of a dictionary attack - literally a machine trying to connect and login over and over again using usernames and passwords from a dictionary.

In this situation you can create a collection of firewalling rules which will deny access from remote clients who attempt to connect "too many" times.
