This chapter discusses a number of related topics pertaining to name server maintenance. We'll talk about commands you can (and can't) send to a running name server, modifying the zone datafiles, and keeping the root name server cache file up to date. We'll also list common Event Log messages. This chapter doesn't cover troubleshooting problems. Maintenance involves keeping your data current and watching over your name servers as they operate. Troubleshooting involves putting out fires those little DNS emergencies that flare up periodically. Firefighting is covered in Chapter 15. |
