Change the node name (system name) to
nodename. nodename is restricted to characters
(see uname(2)). See Only users with appropriate
privileges can use the option.
When you execute the command it produces output like the following:
The displayed fields are interpreted as follows:
The operating system name (option
The UUCP network system name by which the system is known
The operating system release identifier
The operating system version identifier
The machine and model numbers
The machine identification number
The operating system license level
It is recommended that the command or the command be used to obtain the
model name, since future model names may not be compatible with See
model(1) and getconf(1).
Many types of networking services are supported on HP-UX, each of which
uses a separately assigned system name and naming convention. To
ensure predictable system behavior, it is essential that system names
(also called host names or node names) be assigned in such a manner
that they do not create conflicts when the various networking facili‐
ties interact with each other.
The system does not rely on a single system name in a specific loca‐
tion, partly because different services use dissimilar name formats as
explained below. The and commands assign system names as follows:
|Node Name |Command |name Format |Used By |
|Internet name |hostname name |sys[.x.y.z...] |ARPA and NFS Services |
|UUCP name |uname -S name |sys |uucp, related programs |
where sys represents the assigned system name. It is recommended that
sys be identical for all commands and locations and that the optional
follow the specified notation for the particular ARPA/NFS environment.
Internet names are also frequently called host names or domain names
(which are different from NFS domain names). Refer to hostname(5) for
more information about Internet naming conventions.
Whenever the system name is changed in any file or by the use of any of
the above commands, it should also be changed in all other locations as
well. Other files or commands in addition to those above (such as if
used to circumvent for example) may contain or alter system names. To
ensure correct operation, they should also use the same system name.
System names are normally assigned by the script at start-up, and
should not be altered elsewhere.
Setting a nodename of more than 8 bytes is possible only with the
appropriate configuration options enabled. It is strongly recommended
that all related documentation be completely understood before setting
a larger node name. A node name larger than 8 bytes can cause anoma‐
lous or incorrect behavior in applications which use the command or the
system function to access the name.
