NAME
nodehostnamesize — size of node name and host name
DESCRIPTION
The HP-UX operating system default configuration allows the system
node name and host name to be up to 8 and 64 bytes in
length, respectively.
The node name supports the UUCP utilities.
The host name supports the internet Domain Name
Services (DNS) host name label.
Setting a node name of more than 8 bytes or a host name of more than 64
bytes is possible only with the appropriate configuration options
enabled.
APPLICATION USAGE
See the whitepaper
Node and Host Name Sizes on HP-UX: Using the Expanded Capabilities
for more information.
WARNINGS
It is strongly recommended that all related documentation be
completely understood before setting a larger node or host name.
A node name larger than 8 bytes, or host name larger than 64 bytes, can
cause anomalous behavior or failure in applications which use the
uname
and/or
hostname
commands or the
uname()
and/or
gethostname()
system functions to obtain the names.
