<h1 class="topictitle1">Remote support</h1>
<div><p>In some cases, IBM<sup>®</sup> support personnel can connect directly to your server
to try to determine the sources of a problem.</p>
<p>IBM can
use any of the following methods to connect to your server if you have enabled
the connection: </p>
<div class="section"><h4 class="sectiontitle">Virtual private networking</h4><p>Virtual private networking
(VPN) uses several important TCP/IP protocols to protect data traffic. If
electronic customer support has been configured to use one of the Universal
Connection VPN connectivity options, you can use the Start Remote Support
(STRRMTSPT) command with the *VPN option.</p>
</div>
<div class="section"><h4 class="sectiontitle">Point-to-Point Protocol</h4><p>Point-to-Point Protocol
(PPP) is an Internet standard for transmitting data over serial lines. It
is the most widely used connection protocol among Internet service providers
(ISPs). PPP allows individual computers to access networks, which in turn
provide access to the Internet. The iSeries™ server includes TCP/IP PPP support
as part of its wide-area network (WAN) connectivity. The *PPP option of the
Start Remote Support (STRRMTSPT) command has additional details.</p>
</div>
<div class="section"><h4 class="sectiontitle">Systems Network Architecture</h4><p>In IBM networks,
SNA is the layered logical structure, formats, protocols, and operational
sequences that are used for transmitting information units through networks.
SNA also controls the configuration and operation of networks. Advanced Program-to-Program
Communication (APPC), Advanced Peer-to-Peer Networking (APPN), and High-Performance
Routing (HPR) are some examples of the protocols included within SNA. They
can be used to connect the iSeries server with other <span class="keyword">IBM Systems</span>,
or non-IBM systems, to connect remote controllers, and to maintain a high
level of security on your system. The *VRT option of the Start Remote Support
(STRRMTSPT) command has more details.</p>
</div>
<div class="section"><h4 class="sectiontitle">Remote Service Support Facility</h4><p>Allows IBM support
diagnostic access to the Licensed Internal Code of the server.</p>
<p>If a
support person determines that this method is the best way to diagnose and
fix your problem, you will be given detailed information about how to enable
the connection.</p>
