That doesn't work. The nrpe protocol changed between 1.x and 2.x, so
you need to make sure you're using the same (major) version of nrpe
on both ends of the connection.

I faintly remember having to make some modifications to (check_)nrpe
2.x for it to compile cleanly on solaris, although I think that was
an older version of it than yours. If you run into similar problems,
poke me and I'll see if I can find the modified sources somewhere.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
