Hoe kunnen we helpen?
After installing Nagios NRPE on a new Raspberry host the Nagios server was unable to poll the nrpe plugin of the Raspberry. Strangely enough it was possible to poll the Raspberry via the CLI of the Nagios server. In the server’s syslog the line ‘Remote xxx.xxx.xxx.xxx does not support Version 3 Packets’ was logged on every attempt to poll the Raspberry.
This issue was solved by edit the file ‘commands.cfg’ of the Nagios server by adding the argument ‘-2’ to the affected command lines. This forces to use version 2 packets only.
