The denyhosts software has only been lightly maintained in EPEL for many
years; the EPEL6 branch could have been considered to be unmaintained.
It does not properly support modern system features such as systemd or
firewalld and generally expects to be able to make use of the hosts.deny
file. It appears to be mostly unmaintained upstream. (A beta release
appeared in 2015 but nothing seems to have happened since then.)
Since I have retired the software in Fedora, I have also retired it in
EPEL6 and EPEL7. It should disappear from the repositories soon. If
you have it installed then of course it isn't going anywhere, and all of
the packages which were released will still be available from the Fedora
build system at
Should someone wish to do the work to keep the software alive in EPEL
(or in Fedora), I will certainly be happy to help get that set up.
Otherwise, if you are using the EPEL denyhosts packages, I would
strongly suggest that you consider using fail2ban instead.
