Hello,

I am trying to Puppetize (if that's a word) our NRPE configurations. I notice that the nagios user/group is created along with the nrpe user/group. Is it necessary for clients that Nagios is monitoring to have the nagios user/group created? I'm just trying to see if I need to bother with having both nrpe and nagios user together on the same server.

Code: Select all

(PRO-BOY|jenglish@boy-adams2 manifests)$ sudo grep 'nrpe\|nagios' /etc/{passwd,shadow,group}
(PRO-BOY|jenglish@boy-adams2 manifests)$ sudo puppet apply master.pp
[snip]
(PRO-BOY|jenglish@boy-adams2 manifests)$ sudo grep 'nrpe\|nagios' /etc/{passwd,shadow,group}
/etc/passwd:nrpe:x:393:299:NRPE user for the NRPE service:/var/run/nrpe:/sbin/nologin
/etc/shadow:nrpe:!!:17771::::::
/etc/group:nrpe:x:299:nrpe
/etc/group:nagios:x:292:nrpe

Hello, @jenglish. Usually, nrpe agent on the clients side runs under the nagios user. Take a look at the /usr/local/nagios/etc/nrpe.cfg file:

# NRPE USER
# This determines the effective user that the NRPE daemon should run as.
# You can either supply a username or a UID.
#
# NOTE: This option is ignored if NRPE is running under either inetd or xinetd

nrpe_user=nagios

So yes, you'd need to add the nagios user and group.

Okay. I will leave those then. Based on some systemd issues I had with user + sudoers file, I had come to believe that nrpe user was the only user.

Thank you. This has resolved my question. Please lock thread.
