Nagios Support Forum

Hi,

When we execute the following check command we are getting following error.

[root@nagios libexec]# ./check_nrpe -H host1 -p 5666 -c CheckEventLog -a filter=new file=system MaxWarn=1 MaxCrit=1 filter-generated=\>5m filter+eventID=="10004" filter+eventType==error filter+eventSource==DCOM filter=in filter=all truncate=30
CHECK_NRPE: Receive header underflow - only 0 bytes received (4 expected).


[root@nagios]# ./check_nrpe -H host1 -p 5666
I (0.3.5.1 2008-09-24) seem to be doing fine...

[root@nagios]# ./check_nrpe -H host1
I (0.3.5.1 2008-09-24) seem to be doing fine...


I truncated the command and tried.

[root@nagios]# ./check_nrpe -H host1 -p 5666 -c CheckEventLog -a filter=new file=system
CHECK_NRPE: Receive header underflow - only 0 bytes received (4 expected).



What is wrong in the check command.

Please help me.

The NSClient++ agent you are running is very old and I recommend upgrading to a newer version if possible.

The error is caused be a missing option in the NSClient++ ini file so can you go to the following folder Get the nsc.ini file and upload it here so we can view it?

I replied to the user asking for details.

I will get back to you once I get the details from the user.

Hi,

Please find the details

NSClient++ version is NSClientpp (Nagios) 0.3.5.2 2008-09-24 w32.

Uploaded nsc.ini file

That agent is 11 years old so I don't know if what I suggest will work.

Edit the nsc.ini file and under the [NRPE] section, change the following from to Save the change and restart NSClient++ and test the command.
