check_nfs_local

#!/bin/sh
#
# Verify that services needed for NFS to work are correctly running
# This is a debian-specific check since it uses exit codes from service init scripts.
#
# Note: this is not the panacea of all NFS checks. The real deal should be to
# actually open rpc connections from another server and verify that nfs is
# working correctly. However, because of some limitations if you can't open up
# rpc connections from your nagios servers to the NFS server the current check
# should help out monitoring at least if services are supposed to be running.
