Nagios / NRPE “NRPE: Unable to read output”

New server, copying over some existing NRPE-based checks in Zenoss, but they all error out with “NRPE: Unable to read output” despite all of the commands actually working. /etc/sudoers has the nagios user listed properly, so what’s the problem?

The problem is this line in /etc/sudoers:

Defaults    requiretty

Comment that line out, restart nrpe and it works.

Blog rename again

I hate calling this site “Evan Hoffman’s Blog,” but it seems that when I Googled my own name most of the results were about this guy. So let me just clarify… that’s not me. I enjoyed having the title be obscure lyrics from songs I love but drastic times call for drastic measures. And let me tell you… renaming a blog is serious business.
