Quick question, can I use fedora EPEL 6 packages on redhat RHEL 6 ? Or will fail2ban be part of RHEL 6 repository in future? If answer to both is no then I will proceed installing fail2ban from source package which shouldn't take long time anyways.

Thanks

EPEL is intended to be "a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL)." Recommended reading: http://fedoraproject.org/wiki/EPEL . If fail2ban ever gets into RHEL 6 proper, the EPEL 6 package will be retired and you can use that.

So, yes, you can use this on RHEL 6. That is what EPEL 6 is for. 

By the way, the bodhi comments above are broken. You'll want to run "yum --enablerepo=epel-testing update fail2ban" , using "epel-testing", not "updates-testing". Once you've installed it and tested it, you can then leave feedback in Bodhi to encourage maxamillion to push this to EPEL stable :)

Thank you Ken, really appreciate your quick and informative reply. I will do the recommended reading and try the test rpm on a non production box first and of course update you all how that goes.

Good day

Ken provided an awesome response about the EPEL 6 bit so I won't duplicate effort, but on the topic of RHEL6 inclusion.... that is honestly entirely up to Red Hat and I'm not sure what their plans are for the future. If in the event they do select fail2ban as a package they want to maintain and include in the official repositories it will no longer be available in EPEL6 or will be left at the version it is at upon the decision to ship it in the official repositories so that the official Red Hat package would take precedence (via version and/or release number).

fail2ban-0.8.4-24.el6 has been pushed to the Fedora EPEL 6 stable repository.
