+<p><em>Chap-secret</em> is the module of authentication which works with user authentication data and other data (username, password, ip address, speed etc.) stored as local file. Currently <em>accel-ppp</em> may works only with one of the authentication method, chap-secrets or RADIUS. RADIUS has more priority if set in <code class="docutils literal notranslate"><span class="pre">[modules]</span></code> section. Remove or <em>#comment</em> <code class="docutils literal notranslate"><span class="pre">radius</span></code> from section <code class="docutils literal notranslate"><span class="pre">[modules]</span></code> if you want use <code class="docutils literal notranslate"><span class="pre">chap-secrets</span></code>.

+<p>Method authentication users, control sessions and delivery without any tunnel “called” as IPoE (IP over Ethernet).
+Accel-ppp support L2 and L3 topologies and start sessions on DHCP Discover or unclassified packet.</p>
+<p>Develop auxiliary kernel module for sessions start on unclassified packet and shared interfaces.
+This module creates virtual interface, an analogue of ifb and used for sessions shaper and One-to-one NAT.</p>
+<p>The difference between L2 and L3. L2 incoming packet will be checked for the mac address set at the session start, and outgoing packets will be sent straight to this mac address without additional ARP requests, which provides protection against IP/mac address spoofing.
+In the case of L3, the outgoing packet will be routed according to the established routing rules.</p>

+<p>More modern load balancing mechanism based on weight.</p>
+<p>How it works:
+On reception of DHCPDISCOVER accel-ppp sends broadcast DHCP message to port 67 with same xid and add special vendor-specific option where encodes its current session count multiplied by weight. On reception of such message accel-ppp searches session with same xid and compares weight. If received weight is less than session’s weight then it terminates this session.
+May be used as per-interface.</p>

+</dd>
+<dt><strong>host-name=string</strong></dt><dd><p>By default <code class="docutils literal notranslate"><span class="pre">host-name=accel-ppp</span></code></p>
+<p>This name will be sent to clients in Host-Name attribute.</p>
+</dd>
+<dt><strong>hello-interval=n</strong></dt><dd><p>By default <code class="docutils literal notranslate"><span class="pre">hello-interval=60</span></code></p>
+<p>Specifies interval in seconds to send Hello control message. Its used for keep alive connection. If peer will not respond to <em>Hello</em> connection will be terminated.</p>
+</dd>
+<dt><strong>recv-window=n</strong></dt><dd><p>By default <code class="docutils literal notranslate"><span class="pre">recv-window=16</span></code> Available value range 1-32768.</p>
+<p>Set the size of the local receive window. Only received messages whose sequence number is in the range [last-Nr + 1, last-Nr + recv-window] are accepted (where last-Nr is the sequence number of the last acknowledged message).</p>
+</dd>
+<dt><strong>timeout=n</strong></dt><dd><p>By default <code class="docutils literal notranslate"><span class="pre">timeout=60</span></code></p>

+<dt><strong>rtimeout=n</strong></dt><dd><blockquote>
+<div><p>By default <code class="docutils literal notranslate"><span class="pre">timeout=1</span></code></p>
+</div></blockquote>
+<p>Specifies timeout (in seconds) to wait message acknowledge, if elapsed message retransmission will be performed. Timeout is multiplied by two after each retransmission. So if rtimeout is set to 1, first retransmission will occur after one second, second retransmission two seconds later, third one four seconds later, and so on, until a reply is received or the retransmit value is reached.</p>
+</dd>
+<dt><strong>rtimeout-cap=n</strong></dt><dd><p>By default <code class="docutils literal notranslate"><span class="pre">rtimeout-cap=16</span></code></p>
+<p>Set the maximum interval between retransmissions. The exponential backoff interval used by rtimeout will never grow above rtimeout-cap. rtimeout-cap must be higher than rtimeout and, according to RFC 2661, must be no less than 8 (though accel-ppp doesn’t enforce this rule).</p>

+<p>Default behavior - don’t ask client for mppe, but allow it if client wants.</p>
+</dd>
+<dt><strong>secret=string</strong></dt><dd><p>By default is not defined.</p>
+<p>Specifies secret to connect to server.</p>
+</dd>
+<dt><strong>hide-avps=0|1</strong></dt><dd><p>By default <code class="docutils literal notranslate"><span class="pre">hide-avps=0</span></code></p>

+</dd>
+<dt><strong>dataseq=deny|allow|prefer|require</strong></dt><dd><p>By default <code class="docutils literal notranslate"><span class="pre">dataseq=allow</span></code></p>
+<p>Specify data sequencing negotiation algorithm:</p>
+<ul class="simple">
+<li><p>deny - don’t send data packets with sequence numbers</p></li>
+<li><p>allow - send data packets with sequence numbers if peer have requested so only</p></li>
+<li><p>prefer - send data packets with sequence numbers and enable same for peer</p></li>
+<li><p>require - send data packets with sequence numbers and enforce same for peer</p></li>

+</dd>
+<dt><strong>reorder-timeout=n</strong></dt><dd><p>By default <code class="docutils literal notranslate"><span class="pre">reorder-timeout=0</span></code></p>

+</dd>
+</dl>
+<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>[shaper]
+time-range=1,1:00-3:00
+time-range=2,3:00-5:00
+time-range=3,5:00-7:00
+</pre></div>
+</div>
+<p>The first number is time range identifier. To define a specific rates uses following format of radius attributes: range-id,rate, range-id,down-rate/up-rate or cisco-like.</p>
+<p>As an example:</p>
+<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>Filter-Id=1000
+Filter-Id=1,2000
+Filter-Id=2,3000
+Filter-Id=3,4000
+</pre></div>
+</div>
+<p>That means: set 1000Kbit by default, set 2000Kbit in time range 1, set 3000Kbit in time range 2 and set 4000Kbit in time range 3.
+You have to pass multiple Filter-Id attributes to utilize this functionality.</p>
