Hi

I have started noticing this on our Windows Servers
CHECK_NRPE: Invalid packet version received from server.

I have upgraded the NSClient Agent to what I think is the latest version
NSCP-0.5.2.35-x64.msi

But I still get the message

The only way to get the Windows systems to report correct is by editing the check_nrpe command to
$USER1$/check_nrpe -2 -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$

Adding the -2

Thanks

Hi,

$USER1$/check_nrpe -2 -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$

If you're running the later version of check_nrpe, you'll need to add this option since we've updated the TCP packet structure in version 4, and adding this will use the older packet types.

If you have to make the changes across of a number of hosts or services, the Bulk Mods tool is helpful here.
