while the operating system is in restricted state.</p>
|

|
<div class="section"><h4 class="sectiontitle">Situation</h4><p>As the network administrator,
|
||
|
|
you need to obtain backup status reports for your server. When you are running
|
||
|
|
backup procedures, the operating system must be in restricted state to prevent
|
||
|
|
users from changing any configuration. Because you are remote, you access
|
||
|
|
status reports using a personal digital assistant (PDA) device (or any TCP/IP
|
||
|
|
networking device). The PDA uses a sockets-enabled application that requires
|
||
|
|
an active TCP/IP interface available to communicate with the server. To allow
|
||
|
|
this communication, you must first start TCP/IP using special parameters.
|
||
|
|
After you start TCP/IP, you will need to start a specific TCP/IP interface
|
||
|
|
to allow access to the system. The information below provides more detail.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Restrictions</h4><div class="p">The following restrictions
|
||
|
|
apply when the operating system is running in restricted state: <ul><li>Cannot start TCP/IP servers (<span class="cmdname">STRTCPSRV</span> CL command),
|
||
|
|
since they require active subsystems.</li>
|
||
|
|
<li>Can only start one interface for a specific line type (Ethernet, token-ring,
|
||
|
|
or DDI) that is not attached to a network server description (NWSD) or a network
|

|
interface description (NWID).</li>

These are the only parameters accepted when the operating system is in restricted

start TCP/IP application servers or IP interfaces.<img src="./deltaend.gif" alt="End of change" /></p>
