run that command as icinga user, not as root. maybe a permissions
problem?
from the commandline it works with both users, root and icinga
run a tcpdump 'host <your icinga host>' on the remote machine where nrpe
is running, and watch if the handshake is able to continue. probably add
'port 5668' if you don't want the ssh handshakes (or grep properly).
tcpdump shows that there is no traffic between the icinga-server and the
remote host, but when I run the check-command from commandline a
connection is established successfully.
That's what icinga says, when I reschedule a service check in the
icinga-web:
