The set safemode command disables DNS and DHCP services. Use this command to troubleshoot a NIOS appliance with unreliable services.
This command restarts all the services, including DNS and DHCP. DNS and DHCP remain active only long enough to write named.conf and dhcp.conf files. These services then shut down. All other services remain functional. This allows you to review the named.conf and dhcp.conf files to determine and alleviate the cause of the appliance distress.
Once you have determined the problem, you can reinstate DNS and DHCP services using the the set nosafemode command.
