Managing Serviceguard Eighteenth Edition, September 2010

on each node you intend to configure into the cluster, and ensure that the entry for the
root user comes before any other entry with a UID of 0.
NOTE: You need to do this even if you plan to use cmpreparecl (1m)
orcmpdeploycl (1m), which calls cmpreparecl. For more information about these
commands, see “Using Easy Deployment Commands to Configure the Cluster”
(page 211).
About identd
HP strongly recommends that you use identd for user verification, so you should
make sure that each prospective cluster node is configured to run it. identd is usually
started by inetd from /etc/inetd.conf.
NOTE: If you plan to use cmpreparecl (1m) (or cmpdeploycl (1m), which calls
cmpreparecl), you can skip the rest of this subsection.
Make sure that a line such as the following is uncommented in /etc/inetd.conf:
auth stream tcp6 wait bin /usr/lbin/identd identd
NOTE: If the -T option to identd is available on your system, you should set it to
120 (-T120); this ensures that a connection inadvertently left open will be closed after
two minutes. In this case, the identd entry in /etc/inetd.conf should look like
this:
auth stream tcp6 wait bin /usr/lbin/identd identd -T120
Check the man page for identd to determine whether the -T option is supported for
your version of identd
(It is possible to disable identd, though HP recommends against doing so. If for some
reason you have to disable identd, see “Disabling identd” (page 276).)
For more information about identd, see the white paper Securing Serviceguard at
www.hp.com/go/hpux-serviceguard-docs, and the identd (1M) manpage.
Configuring Name Resolution
Serviceguard uses the name resolution services built into HP-UX.
