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.
