I was looking for solutions to your issue, and came across a solaris agent:

Code: Select all

cd /tmp
wget http://assets.nagios.com/downloads/nagiosxi/agents/solaris-nrpe-agent.tar.gz
tar xzf solaris-nrpe-agent.tar.gz
cd solaris-nrpe-agent
./fullinstall

This may only work for Solaris 10+, but I figured I would throw this procedure your way since it's quite simple and may resolve the problem.

Hi Jolson,

It did not work on Solaris 9. I tried with that already. Event went to modify the script to identify the machine as solaris 9. But no luck.

Best way would be to figure out the problem with compiling on solaris 9. Or to make someone compile on a solaris9 machine and to get the binary.

Have you checked: https://www.opencsw.org/ for any potential packages?

Solaris 10 is still supported, Solaris 9 is not as of last year.

I compiled a more time-period appropriate version of NRPE on Solaris 9 - it went fine:

Code: Select all

bash-2.05# uname -a
SunOS unknown 5.9 Generic_118559-11 i86pc i386 i86pc
bash-2.05# ./nrpe

Usage: nrpe [-n] -c <config_file> <mode>

Options:
 -n            = Do not use SSL
 <config_file> = Name of config file to use
 <mode>        = One of the following two operating modes:
   -i          =    Run as a service under inetd or xinetd
   -d          =    Run as a standalone daemon

Notes:
This program is designed to process requests from the check_nrpe
plugin on the host(s) running Nagios.  It can run as a service
under inetd or xinetd (read the docs for info on this), or as a
standalone daemon. Once a request is received from an authorized
host, NRPE will execute the command/plugin (as defined in the
config file) and return the plugin output and return code to the
check_nrpe plugin.

Looks like your /etc/inet/nrpe is pointing to the wrong config file:

Code: Select all

server_args     = -c /usr/local/nagios/etc/nrpe.cfg --inetd

Should be:

Code: Select all

server_args     = -c /etc/nagios/nrpe.cfg --inetd

Or was that a posting mistake?

Code: Select all

/etc/init.d/inetsvc stop
/etc/init.d/inetsvc start

No good; still the same error.
