I tried to install nagios plugins and nrpe to hp-ux systems. I don't have much trouble with hp-ux 11.11. I can not compile the plugins in pa-risc 11.23, but I can use those compiled in 11.11 on them without any problem.
Finally, I tried to install them to itanium virtual systems. Both plugins and nrpe are compiled without any problem. But when I start nrpe daemon, I got the error:
/usr/local/nagios/nrpe -c /usr/local/nagios/nrpe.cfg -d
/usr/lib/hpux32/dld.so: Unsatisfied data symbol 'rfc931_timeout' in load module '/usr/lib/hpux32/libwrap.so'.
I compiled them in gcc and cc, but both of them got the same messages.
