Wohoo!
Here we go: Nagios 3.0Beta7 and PNP 0.4.4! Tested, works for me ;-)
If you always want to use my "current" (read: tested in my installations) packages just put these lines in your sources.list
:
deb http://people.teamix.net/~svelt/debian/etch/nagios3/current/ ./
deb http://people.teamix.net/~svelt/debian/etch/ndoutils/current/ ./
deb http://people.teamix.net/~svelt/debian/etch/pnp/current/ ./
Have fun & send feeback!
