One of my servers was getting hit with what appeared to be a DoS attack against ProFTPD 1.2.4. I checked the ProFTPD website and it did have a DoS attack listed, but said it was fixed in version 1.2.2. I updated to the newest RC 1.2.5rc1 and haven't been attacked since. Basically ProFTPD was using all system resources until the server crashed. Any ideas?
