You can tailor the log messages to output the subnet type.<br>
<br>
Add the two "subnet_type"s (below in your config) and this to
dhcpd.conf:<br>
<font color="#993300"><tt>on commit {</tt><tt><br>
</tt><tt> log ( info,</tt><tt><br>
</tt><tt> concat (</tt><tt><br>
</tt><tt> "Subnet-type", subnet_type,</tt><tt><br>
</tt><tt>.</tt><tt><br>
</tt><tt>.</tt><tt><br>
</tt><tt> )</tt><tt><br>
</tt><tt> );</tt><tt><br>
</tt><tt>}</tt><tt><br>
</tt></font><br>
Then in rsyslog.conf (just after the #### RULES #### line):<br>
<font color="#993300"><tt>if $programname == 'dhcpd' then {</tt><tt><br>
</tt><tt> if $msg contains 'Faculty' then {</tt><tt><br>
</tt><tt> action(type="omfile"
file="/var/log/dhcpd/dhcp-faculty.log")</tt><tt><br>
</tt><tt> # if $syslogseverity >= 4 then stop #
warning</tt><tt><br>
</tt><tt>
# if $syslogseverity >= 5 then stop # notice</tt><tt><br>
</tt><tt>
if $syslogseverity >= 6 then stop # info</tt><tt><br>
</tt><tt> }</tt><tt><br>
</tt><tt> if $msg contains 'Student' then {</tt><tt><br>
</tt><tt> </tt><tt>action(type="omfile"
file="/var/log/dhcpd/dhcp-student.log")</tt><tt><br>
</tt><tt> # if $syslogseverity >= 4 then stop #
warning</tt><tt><br>
</tt><tt>
# if $syslogseverity >= 5 then stop # notice</tt><tt><br>
</tt><tt>
if $syslogseverity >= 6 then stop # info</tt><tt><br>
</tt><tt>
}</tt><tt><br>
</tt><tt>
}</tt><tt><br>
</tt></font><br>
This should split out the log messages. Syslog facility 'notice'
and above still go to<br>
the regular log file. Don't forget to restart or reload rsyslogd.<br>
