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.
These configuration options are only available if you have installed the
optional NodeHostNameXpnd product.
APPLICATION USAGE
See the whitepaper
Node and Host Name Sizes on HP-UX,
included with the
optional NodeHostNameXpnd product and installed at
usr/share/doc/NodeHostNameSize.pdf,
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.
