Can any body pls give a solution for it, i didnt get it wat kind of problem it is...........

cd ./src/ && make install-plugin
make[1]: Entering directory `/usr/local/src/nrpe-2.12/src'
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/libexec
/usr/bin/install -c -m 775 -o nagios -g nagios check_nrpe /usr/local/nagios/libexec
make[1]: Leaving directory `/usr/local/src/nrpe-2.12/src'

when i try to install other packages it shows the same error....

cd ./src/ && make install-daemon

/usr/bin/install -c -m 775 -o nagios -g nagios nrpe /usr/local/nagios/bin

And if i try to check_nrpe it shows....

Connection refused by host

You are NOT supposed to post your question multiple forums. Please go read the rules.

The make commands did NOT give you any errors - the output was informational.

The error you DID get was using check_nrpe and it clearly tells you connection was refused by local host.

The nrpe plugin has both the plugin (nrpe) which needs to be configured on the client host on which it is being installed (UNIX/Linux) and the check_nrpe command which is to be run from Nagios on the master .

Typically the configuration file is in /usr/local/nagios/etc/nrpe.cfg. Default port is 1556.

Since you tried "localhost" presumably you're attempting to test the master itself so it is both the Nagios master AND the NRPE client. First check your nrpe.cfg to see what port it specified. Then check to see if nrpe is running (ps -ef |grep -i nrpe" OR is setup in xinetd.d to run from there (this will also specify port). Run "lsof -i :<port>" to see if anything is listening (e.g. "lsof -i :1556"). If not it means it isn't running nor setup to run in xinetd.

If the port IS listening then it may be a firewall issue but this is less likely on localhost than going to remote hosts. Check iptables to be sure you're not restricting access to the port on localhost that NRPE uses.
