<h1 class="topictitle1">Security considerations for using SLIP</h1>
|
||
|
|
<div><p>TCP/IP support includes Serial Interface Line Protocol (SLIP). </p>
|
||
|
|
<p>SLIP provides low-cost point-to-point connectivity. A SLIP user can connect
|
||
|
|
to a LAN or a WAN by establishing a point-to-point connection with a system
|
||
|
|
that is part of the LAN or WAN. SLIP runs on an asynchronous connection. You
|
||
|
|
can use SLIP for dial-up connection to and from iSeries™ servers. </p>
|
||
|
|
<p>For example, you might use SLIP to dial in from your PC to an iSeries system.
|
||
|
|
After the connection is established, you can use the TELNET application on
|
||
|
|
your PC to connect to the iSeries TELNET server. Or, you can use the FTP application
|
||
|
|
to transfer files between the two systems. </p>
|
||
|
|
<p>No SLIP configuration exists on your system when it ships. Therefore, if
|
||
|
|
you do not want SLIP (and dial-up TCP/IP) to run on your system, do not configure
|
||
|
|
any configuration profiles for SLIP. You use the Work with TCP/IP Point-to-Point
|
||
|
|
(WRKTCPPTP) command to create SLIP configurations. You must have *IOSYSCFG
|
||
|
|
special authority to use the WRKTCPPTP command.</p>
|
||
|
|
<div class="p">If you want SLIP to run on your system, you create one or more SLIP (point-to-point)
|
||
|
|
configuration profiles. You can create configuration profiles with the following
|
||
|
|
operating modes:<ul><li>Dial in (*ANS)</li>
|
||
|
|
<li>Dial out (*DIAL)</li>
|
||
|
|
</ul>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> A user profile is system object that allows signon. Every system
|
||
|
|
job must have a user profile to run. A configuration profile stores information
|
||
|
|
that is used to establish a SLIP connection with an iSeries system. When you start a SLIP
|
||
|
|
connection to iSeries servers,
|
||
|
|
you are simply establishing a link. You have not yet signed on and started
|
||
|
|
an iSeries server
|
||
|
|
job. Therefore, you do not necessarily need a user profile to start a SLIP
|
||
|
|
connection to iSeries servers.
|
||
|
|
However, as you will see in the discussions that follow, the SLIP configuration
|
||
|
|
profile may require a user profile to determine whether to allow the connection.</div>
