Firewall Ports

If you have a firewall between your NEMS Server and your host, you must open incoming TCP connections on ports 5666 and 12489 on your host side.

Since check_nrpe can pose a security risk, please do not open these ports to the world. Rather, ensure your NEMS Server is the only outside IP allowed to connect to these ports.

Host-Side Service

The NRPE service must be installed before check_nrpe can be used to monitor the host.


Fix for NEMS 1.5 and Under

In NEMS Linux 1.5 and lower, an older version of NRPE was used. This can be upgraded by running sudo nems-upgrade however you must also make a few minor changes in NEMS NConf as follows:

  • Edit check_nrpe in checkcommands, changing the command line to: $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ (essentially, just removing the quotation marks).
  • Edit / Disk Space and /var Disk Space in Advanced Services, changing the ARGS to: check_disk -a '-w 80 -c 90 -p /' and check_disk -a '-w 80 -c 90 -p /var' respectively.
