HP-UX System Administrator's Guide: Configuration Management HP-UX 11i v3 (B3921-90017, September 2010)

• Enable shadow passwords (see “Setting Shadow Password Mode” (page 45))
• Use only files type nameserver backends (configured in the file /etc/
nsswitch.conf — see the manpage nsswitch.conf(4) for details)
NOTE: Some third party applications might assume that passwords are limited to
eight characters. These applications will not function correctly if longer passwords are
used. The uucpd daemon does not work with long passwords. Do not enable long
passwords if you plan to use uucpd.
Setting Long User, Group, Host, and File Names
Setting Long User and Group Names
By default, user names are restricted to eight characters and group names to 16
characters. To set long (up to 254-character) user and group names, see lugadmin(1M).
Once long user and group names have been set and used, you should not attempt to
revert to short names.
Setting Long Host Names
If the kernel tunable expanded_node_host_names is off (0), the maximum host
node name length is eight characters (for example, hprdc185) and the maximum full
host name length is 64 characters (for example, hprdc185.example.com). If it is on
(1), the maximum for both is 255 characters. By default, this tunable is off. See
expanded_node_host_names(5) for details.
Setting Long File Names
The convertfs command changes an existing file system to long file names. The
newfs command creates a new file system with short (-S) or long (-L) file names. See
the convertfs(1M) and newfs(1M) manpages and the HP-UX System Administrator’s Guide:
Routine Tasks.
A short name is up to 14 characters; a long name is up to 255 characters. A long file
name system cannot be converted back to short file names.
NOTE: The /usr directory should be in a long file name system, since many manpage
names exceed 14 characters.
Configuring /etc/hosts
You can use any text editor to edit the /etc/hosts file. If you are not running BIND,
you can use HP SMH.
