<div class=WordSection1>
<p class=MsoNormal>I am trying to do detailed logging of DHCP and keep it in a
standard format so that it can be sent to a mysql database with entries for
type (set-top box or data), addy, mac, host-name, AID, CID, and event type
(commit, release, expiry). I have multiple scenarios in which portions of
this data is available. The scenarios are:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>-set-top-box, no host-name, AID, no CID<o:p></o:p></p>
<p class=MsoNormal>-set-top-box, no host-name, AID, CID<o:p></o:p></p>
<p class=MsoNormal>-data, host-name, AID, CID<o:p></o:p></p>
<p class=MsoNormal>-data, host-name, AID, no CID<o:p></o:p></p>
<p class=MsoNormal>-data, no host-name, AID, CID<o:p></o:p></p>
<p class=MsoNormal>-data, no host-name, AID, no CID<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I know this can be accomplished via combinations of if
statements, etc. With the various scenarios, it can get very lengthy and
convoluted. Im looking for a more elegant way to accomplish this.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So that I can just use one set of statements for on commit,
on expiry, on release - is there a way so that when the CID or host-name
does not exist, to set those options within the dhcpd.conf file to a specific
text string to log (i.e. null or ----) . Also can you define variables
within dhcpd.conf to be used within the log statements (i.e. – if option
vendor-class-identifier = “STRING” TYPE = “STB OR DATA”).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
