The
    <a href="cconsole/home_page">Cluster Console</a>
is available in the <tt>SUNWccon</tt> package.  After installation, 
the usage for the three different
    <a href="cconsole/session_types">session types</a>
of Cluster Console are: <p>

<dl>
<dt> <tt>cconsole</tt> [ <i>clustername</i> | <i>hostname</i> ... ]
<dd> Starts the Cluster Console connected to the console(s) of the specified remote host(s) via the
	<a href="cconsole/tc">terminal concentrator</a>
<p>
<dt> <tt>ctelnet</tt> [ <i>clustername</i> | <i>hostname</i> ... ]
<dd> Starts the Cluster Console connected to the specified remote host(s) via
     <tt>telnet</tt>
<p>
<dt> <tt>crlogin</tt>  
     [ <tt>-l</tt> <i>username</i> ]
     [ <i>clustername</i> | <i>hostname</i> ... ]
<dd> Starts Cluster Console connected to the specified remote host(s) via
     <tt>rlogin</tt>.  The <i>username</i> argument (if any), specifies a
     different username to log in as. 
</dl>

If a cluster name is specified, all three commands expand the cluster
name into its component hostnames. <p>

All three commands also take the standard X arguments.
