OK, I've tried to use check_nrpe, but I can't connect to the Windows Client

# ./check_nrpe -H <WindowsClient> -p 5666 -c alias_up
CHECK_NRPE: Error receiving data from host.

When I return to check_nt, I can connect to the Windows Client.

# ./check_nt -H <WindowsClient> -p 5666 -v MEMUSE

(92%) | 'Memory usage'=201.26Mb;0.00;0.00;0.00;2469.98

the Client Logfile shows me:

Whats going on? ;-)

Here is my nsc.ini

;
;# ENCRYPTION METHOD
;   This option determines the method by which the send_nsca client will 
encrypt the packets it sends

balance between security and

resources.

method.

method the nsca daemon uses
