    Very Nice article. I have one suggestion. This article work just fine for Ubuntu 12.04 Server, except installation which can be done with

    sudo apt-get install denyhosts

    So i recomment just add Ubuntu to the list. And add the installation method.

    Hi, am using CentOS release 5.7 (Final), i can’t install denyhosts with yum, provided i have enabled epel repo and logged in as root.

    when i run #yum install denyhosts

    it gives,
    “Setting up Install Process
    No package denyhosts available.
    Nothing to do”

    what is the problem here. pls advice.

    It works nice. Played with the thing and it is fantastic for ssh securities.. Thanks for keeping all things at one place.

  8. I do trust all of the concepts you’ve offered to your post. They’re really convincing and will certainly work. Still, the posts are too brief for newbies. May you please prolong them a bit from next time? Thanks for the post.
