NRPE Install Error

[asam30 at gmail.com]

Scott,

Paste the content of /etc/xinetd.d/nrpe file here.

Please make sure when you telnet from nagios server to remote monitoring
host on 5666, is the connection closed automatically after you execute the
command or you yourself did close the connection by pressing ctrl + ]


To avoid getting, "could not complete ssl hand shake" please follow this.

If you are monitoring the intranet host behind the firewall and sure that
you dont need the ssl then go again and compile nrpe plugins with out the
ssl support.


./configure -disable-ssl   or --disable-ssl (not sure about it, please see
./configure --help for more info)
and then make all , make install.

hope this helps.
please let me know..
