Hi,

bash-3.00# /usr/local/nagios/libexec/check_nrpe -H localhost; tail -f /var/adm/messages
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.
Oct 8 12:37:58 term-ser inetd[21119]: [ID 702911 daemon.error] Failed to set credentials for the inetd_start method of instance svc:/network/nrpe/tcp:default (chdir: No such file or directory)

Correction: my nagios server is on RHEL :slight_smile:

did you install xinetd and start the service?

yes… i have done that… please go through …

bash-3.00# inetadm -l svc:/network/nrpe/tcp:default

bash-3.00# netstat -a | grep nrpe
*.nrpe . 0 0 49152 0 LISTEN

How could i check if xinetd is started???

bash-3.00# ps -ef | grep inet
root 217 1 0 Sep 19 ? 3:33 /usr/lib/inet/xntpd
root 25574 24195 0 13:04:01 pts/65 0:00 grep inet
root 24026 1 0 10:59:24 ? 0:08 /usr/lib/inet/inetd start

Thanks 512

check service xinetd status

Did you check these two things

1.Make sure the nrpe daemon is running under xinetd.
netstat -at | grep nrpe
The output out this command should show something like this:
tcp 0 0 *:nrpe : LISTEN

2.Next, check to make sure the NRPE daemon is functioning properly. To do this, run the check_nrpe plugin that
was installed for testing purposes.
/usr/local/nagios/libexec/check_nrpe -H localhost
You should get a string back that tells you what version of NRPE is installed, like this:
NRPE v2.12

Firstly i am on solaris…
so service xinetd status will not work… :frowning:

  1. also netstat -at | grep nrpe will not work…
    bash-3.00# netstat -an| grep 5666
    *.5666 . 0 0 49152 0 LISTEN

  2. bash-3.00# /usr/local/nagios/libexec/check_nrpe -H localhost; tail -f /var/adm/messages
    CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

I am sorry to say that i did not work on solaris with nrpe.
