I did an upgrade to my Nagios machine (from 2014R to XI 5.5.8).
I have a few scripts which are running on that machine and now I noticed that I have problems with them.
I get the following error:
I did checked the configuration on nrpe.cfg and it seems OK./check_nrpe -H localhost -t 30 -2 -c check_test -a 10.10.10.10 username
CHECK_NRPE: Receive header underflow - only 0 bytes received (4 expected).
NRPE version - NRPE v3.2.1dont_blame_nrpe=1
All my scripts on the local machine were running fine until the upgrade.
Any idea?
