<h2>I don’t see pppd processes, how to manually terminate session ?<a class="headerlink" href="#i-don-t-see-pppd-processes-how-to-manually-terminate-session" title="Link to this heading"></a></h2>
<p>Yes, in fact accel-ppp doesn’t use pppd because it has its own ppp implementation.
To terminate session you may use three methods:</p>
<ol class="arabic simple">
<li><p>Use cli (telnet or tcp):</p></li>
</ol>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>By<span class="w"> </span>default<span class="w"> </span>telnet<span class="w"> </span>listens<span class="w"> </span>connections<span class="w"> </span>on<span class="w"> </span><span class="m">2000</span><span class="w"> </span>port<span class="w"> </span>and<span class="w"> </span>tcp<span class="w"> </span>on<span class="w"> </span><span class="m">2001</span><span class="w"> </span>port.

accel-ppp#<span class="w"> </span>terminate<span class="w"> </span><span class="k">if</span><span class="w"> </span>ppp0
</pre></div>
</div>
<p>or</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>$<span class="w"> </span><span class="nb">echo</span><span class="w"> </span><span class="s1">'terminate if ppp0'</span><span class="w"> </span><span class="p">|</span><span class="w"> </span>nc<span class="w"> </span>-q0<span class="w"> </span><span class="m">127</span>.0.0.1<span class="w"> </span><span class="m">2001</span>
</pre></div>
</div>
<p>There are also other criterias to select session(s), use help cli command to get more information.</p>
<ol class="arabic simple" start="2">
<li><p>Use radius Disconnect-Message:</p></li>
</ol>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>$<span class="w"> </span><span class="nb">echo</span><span class="w"> </span><span class="s1">'NAS-Port=0'</span><span class="w"> </span><span class="p">|</span><span class="w"> </span>radclient<span class="w"> </span><span class="m">127</span>.0.0.1:3799<span class="w"> </span>disconnect<span class="w"> </span>testing123

</pre></div>
</div>
<p>and you can control it in logs:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span><span class="o">[</span><span class="m">2012</span>-01-21<span class="p">|</span><span class="m">16</span>:48:55<span class="o">]</span>:<span class="w"> </span>info:<span class="w"> </span>ppp0:<span class="w"> </span>recv<span class="w"> </span><span class="o">[</span>RADIUS<span class="p">|</span>Disconnect-Request<span class="w"> </span><span class="nv">id</span><span class="o">=</span>aa<span class="w"> </span><NAS-Port<span class="w"> </span><span class="m">0</span>><span class="o">]</span>
