Rules for Using Host Names in NetBackup
NetBackup uses host names to identify, communicate with, and initiate
processes on NetBackup client and server computers. The correct use of host
names during configuration is essential to the proper operation of NetBackup.
Also, see “Dynamic Host Name and IP Addressing” on page 147.
NetBackup uses TCP/IP host names to connect to NetBackup servers and
clients. NetBackup validates its connections by performing a reverse host name
lookup. That is, NetBackup determines the IP address of a connection and then
uses the IP address to look up the host name with
gethostbyaddr()
. For this
to work reliably, the host name and address resolution must be set up correctly
in DNS, WINS, or the local
%Systemroot%\system32\drivers\etc\hosts
file (if necessary).
Note:
Sometimes placing the system host name and IP address in the
%Systemroot%\system32\drivers\etc\hosts
file accelerates name
lookups.
Qualifying Host Names
A major consideration when configuring host names is the extent to which you
qualify them. In many cases, using a computer’s short host name is adequate.
If the network environment is or will eventually be multi-domain, qualify host
names to the extent that servers and clients can identify each other in a multi-
domain environment.
For example, use a name such as
mercury.bdev.null.com
or
mercury.bdev
rather than just mercury.
