Help on CHECK_NRPE: Received 0 bytes from daemon.

[Lori Adams]

I just started getting this same error.  For me it has to do with what
the argument is that I'm passing to nrpe.

I'm attempting to pass a string with '[' or ']' and I get this error:
CHECK_NRPE: Received 0 bytes from daemon.  Check the remote server logs
for error messages.

I haven't figured out where the log is yet to check for error messages.


If the string I pass does not have those brackets, it works.  I have
tried escaping the brackets to no avail.

Thoughts?

Is your nagios host listed as an allowed_hosts in nrpe.cfg? Can you
manually telnet from your nagios host to your nrpe host on port 5666?
Have you tried enabling debug in nrpe.cfg? If the first two are correct,
the last should direct you to what you need to fix.
