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 sup-
ports 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.
