NRPE error "CHECK_NRPE: Response packet had invalid CRC32"

[John Tabasz (jtabasz)]

Hi,

Nagios 2.9
NRPE 2.8.1
Solaris 2.8 on both Client and Server hosts. 

I'm trying to test whether nrpe works on a client host. I have built
nrpe on my server host and copied it to the client. I have inetd set up
to start the nrpe daemon as needed. I'm running into the classic problem
mentioned in the subject. To get this I run, while logged in to the
client box, #/opt/nagios/libexec/check_nrpe -n -H 127.0.0.1 -c
check_procs
The response comes back:
CHECK_NRPE: Response packet had invalid CRC32

I found a reference to a patch for this developed by Simon Kitching some
time in 2003 or 2004 that redirects the STD_ERR of the output of the
check command to /dev/null:
http://osdir.com/ml/network.nagios.devel/2004-03/msg00004.html (It's at
the bottom of the page)

What do I do with this patch? Is it already incorporated into the source
code of Nagios 2.9? 
Does everyone run nrpe as a standalone daemon? Apparantly running this
way causes the STD_ERR to be redirected to /dev/null already. 

I would rather use inetd to control operation of the nrpe. 

Please advise. 

Thanks

John
