for one reason or another, the pam\_abl module stopped working with the latest ssh and i needed alternative. so i created a pam module (written in ruby, using pam-ruby, ruby-pam + sqlite3 libraries) which blocks particular host after pre-set number of failed attempts. anyone interested, the repository is at: [https://zemiak.homelinux.org/viewvc/?root=hostblock](https://zemiak.homelinux.org/viewvc/?root=hostblock) (this is my home server behind adsl line so please be gentle and patient - it is not available all the time). hope someone else finds this usefull… vlad ---
