I have a few comments about the article. (I package denyhosts for Fedora Extras.) You install it via yum, and at that point it is actually configured. A proper config file is already in /etc/denyhosts.cfg, although you can of course tweak it. And there's no need to copy anything into /etc/init.d, because it's already set up. So the procedure is just: yum install denyhosts (edit /etc/denyhosts.cfg to your liking) chkconfig denyhosts on service denyhosts start If you prefer to run denyhosts from cron instead of as a daemon, you can edit /etc/sysconfig/denyhosts and follow the instructions there. Other info related to the Fedora package is in /usr/share/doc/denyhosts*/README.fedora - J<
