Support for protocol 3005 was not added until this summer, and we have not yet released a version of NUT which includes this.

However, depending on how easy it is to rebuild packages in Scientific Linux, you may be able to download a snapshot of NUT (labeled "", but that is just a placeholder version number for the autobuilder) and rebuild. When you say "epel repository", is it the same as for RHEL/Fedora?

Theoretically, you should be able to download the SRPM from here:


install to /usr/src (or something) and rebuild with a NUT snapshot:


If you have questions, let us know - I'm sure there are other users of RPM-based distributions on the list.
