I am getting results locally. I configure another fedora linux as client and configure NRPE. Here also I am getting all results except the ping. Here I am getting error “You must specify a server address or host name “ I also configured debian linux as client and configure NRPE. Here I am not getting any results. It gives message “CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages”. On remote server i.e. debain linux it gives error message: - Aug 30 16:31:45 debianserver snmpd[3426]: Connection from 192.168.157.53 Aug 30 16:31:45 debianserver last message repeated 3 times Aug 30 16:31:51 debianserver identd[26372]: started Aug 30 16:31:54 debianserver snmpd[3426]: [smux_accept] accepted fd 11 from 192.168.157.53:46122 Aug 30 16:31:57 debianserver snmpd[3426]: Connection from 192.168.157.53 Aug 30 16:32:04 debianserver last message repeated 66 times Aug 30 16:33:07 debianserver nrpe[26380]: Error: Request contained command arguments, but argument option is not enabled!
