Hello,<br> If I am not mistaken you can tell the conf file what file and where to put the debug info. By default it goes into messages.<br><ul><li><p><tt class="COMMAND">-p
<var class="REPLACEABLE"><portnum></var></tt> —
Specify the udp port number on which <tt class="COMMAND">dhcpd</tt>
should listen. The default is port 67. The DHCP server transmits
responses to the DHCP clients at a port number one greater than
the udp port specified. For example, if the default port 67 is
used, the server listens on port 67 for requests and responses to
the client on port 68. If a port is specified here and the DHCP
relay agent is used, the same port on which the DHCP relay agent
should listen must be specified. Refer to <a href="http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/3/html/System_Administration_Guide/s1-dhcp-configuring-server.html#DHCP-RELAY-AGENT">Section 25.2.4 <i>DHCP Relay Agent</i></a> for details.
</p></li><li><p><tt class="COMMAND">-f</tt> — Run the daemon as a foreground
process. This is mostly used for debugging.
</p></li><li><p><tt class="COMMAND">-d</tt> — Log the DHCP server daemon to the
standard error descriptor. This is mostly used for debugging. If
this is not specified, the log is written to
<tt class="FILENAME">/var/log/messages</tt>.
</p></li><li><p><tt class="COMMAND">-cf <var class="REPLACEABLE"><filename></var></tt> —
Specify the location of the configuration file. The default
location is <tt class="FILENAME">/etc/dhcpd.conf</tt>.
</p></li><li><p><tt class="COMMAND">-lf <var class="REPLACEABLE"><filename></var></tt>
— Specify the location of the lease database file. If a
lease database file already exists, it is very important that the
same file be used every time the DHCP server is started. It is
strongly recommended that this option only be used for debugging
purposes on non-production machines. The default location is
<tt class="FILENAME">/var/lib/dhcp/dhcpd.leases</tt>.
</p></li><li><p><tt class="COMMAND">-q</tt> — Do not print the entire copyright
message when starting the daemon.
