Timeline (Deadlines or Time-Constraints) :

What must be done before this process is started:

Which processes are waiting for this process:

Source documents or communication with information needed for this process:

Machine or Website name and IP address to be added.

What is the end-result of this process, or the hand-off

An nslookup of the machine name will return the IP address. An nslookup of the Ip address will return the machine name.

What steps must be taken independent of the computer system (Manual Process)

Which steps must be taken on a computer (Electronic Process):

- Login to Darth (Primary DNS Server) - Assume root security "su -" - Change directory to the location of the "named" file cd /var/named - Edit the database file you wish to modify vi db.sbccd.cc.ca.us - Add the appropriate A, MX or CNAME record - Modify the Serial field on the third line of the file. The Serial field is made from the current year, month, day and a revision number for that day. yyyymmdd## - Save the file :wq - Edit any additional database files necessary - Restart the DNS services with the new settings /etc/rc.d/init.d/named restart Logoff the machine

Related Documents to Process (e.g. Datatel documentation, Government code books, etc.)

Most Linux/Unix books have examples on editing the named databases: named.ca, named.rev, named.local. These are done in the same fashion.

Notes (Cautions, suggestions for improvement, etc.)

When adding a machine to a DNS name database ie db.sbccd.org, make sure to update the appropriate database for the IP range ie db.207.233.39 for reverse lookup.
