How to add new hosts to the name server data base: 1) Edit 'named.hosts' file: For each machine you need to enter the following information: machine name, all its network addresses, host information, and common aliases for it. This is the entry for calder. CALDER IN A 128.32.130.1 IN A 128.32.129.3 IN HINFO VAX-11/750 UNIX UCBCALDER IN CNAME CALDER For the machine you are adding: 1) replace 'CALDER' with the new machine name 2) replace '128.32.130.1' with the new machines address if there is more then one address for the machine then add lines like the one with '128.32.129.3' 3) replace 'VAX-11/750' with the machine type 4) If it doesn't run 'UNIX' then replace UNIX with its operating system. 2) Edit 'named.rev' file: For each address of a machine you need to enter the reverse address notation for the machine: For calder the lines look as follows: 12.0 IN PTR CALDER.BERKELEY.EDU. 3.129 IN PTR CALDER.BERKELEY.EDU. Calder has two address '128.32.0.12' and '128.32.129.3' You take the two numbers after 128.32 and reverse them. Then replace CALDER with the new machine name. *** Note the trailing "." on "EDU." it needs to be there. Otherwise BIND will add the current $ORIGIN to this name, which won't work. *** 3) Increment the serial number on both files.
