<h1 class="topictitle1">Troubleshoot VPN with the VPN job logs</h1>
<div><p>Describes the various job logs that VPN uses.</p>
<p>When you encounter problems with your VPN connections, it is always advisable
to analyze the job logs. In fact, there are several job logs that contain
error messages and other information related to a VPN environment.</p>
<p>It is important that you analyze job logs on both sides of the connection
if both sides are <span class="keyword">iSeries™</span> systems.
When a dynamic connection fails to start, it is helpful if you understand
what is happening on the remote system.</p>
<p>The VPN jobs, QTOVMAN and QTOKVPNIKE, run in the subsystem QSYSWRK. You
can view their respective job logs from <span class="keyword">iSeries Navigator</span>.</p>
<p>This section introduces the most important jobs for a VPN environment.
The following list shows the job names with a brief explanation of what the
job is used for:</p>
<dl><dt class="dlterm">QTCPIP</dt>
<dd>This job is the base job that starts all the TCP/IP interfaces. If you
have fundamental problems with TCP/IP in general, analyze the QTCPIP job log.</dd>
<dt class="dlterm">QTOKVPNIKE</dt>
<dd>The QTOKVPNIKE job is the VPN key manager job. The VPN key manager listens
to UDP port 500 to perform the Internet Key Exchange (IKE) protocol processing.</dd>
<dt class="dlterm">QTOVMAN</dt>
<dd>This job is the connection manager for VPN connections. The related job
log contains messages for every connection attempt that fails.</dd>
<dt class="dlterm">QTPPANSxxx</dt>
<dd>This job is used for PPP dial-up connections. It answers to connection
attempts where *ANS is defined in a PPP profile.</dd>
<dt class="dlterm">QTPPPCTL</dt>
<dd>This is a PPP job for dial-out connections.</dd>
<dt class="dlterm">QTPPPL2TP</dt>
<dd>This is the Layer Two Tunneling Protocol (L2TP) manager job. If you have
problems setting up an L2TP tunnel, look for messages in this job log.</dd>
