Troubleshooting
Problem
If an administrator reconfigured the DHCP server by modifying the /etc/dnsmasq.d/nps file on an IBM Netezza 1000 system, you may discover that it does not proceed through the bootup sequence properly.
Resolving The Problem
To confirm the problem, list the files in the DHCP server configuration directory as follows:
$ ls /etc/dnsmasq.d
nps
nps.old
This is not a legal configuration because directories with names ending with “.d” such as dnsmasq.d must contain only configuration files, and all files in that directory are read when the service starts.
In this example, the “nps.old” file was read after the "nps" file. The "nps.old" file contained an overlapping configuration which took precedence over the correct configuration specified in the “nps” file.
The only way to solve the problem is to delete any files which are not valid configuration files. (You cannot resolve this problem by re-installing Netezza, by restarting the host, or by restarting the DHCP server.)
In general you should not reconfigure the DHCP server by modifying the /etc/dnsmasq.d/nps file. If you must reconfigure it, do not leave backup files in the /etc/dnsmasq.d directory.
