[Dnsmasq-discuss] Logging of DHCP activity

[dnsmasq at lovelady.com]

Hi, All:

 

I woke today to find that for the second time my /var/log filesytem was full
due to the size of the messages log.  This time and last time, the log was
over 95% due to dhcp logging, and I don't understand why.   I have commented
out the log-dhcp line in /opt/etc/dnsmasq.conf (where my configuration
lives), and have moved the messages file and restarted (rebooted) the
server.  Each time, the logging of dhcp requests begins flooding anew.

 

These requests seem to come from a pair of interfaces on a Winblows 7
machine, if that makes any difference, and apparently were the result of
this configuration line:

 

dhcp-host=00:1d:09:59:7b:7c,00:21:5c:6a:03:ef,192.168.0.10,m1330c

 

. because I had interpreted the manual differently.  Clarity has arrived - I
have disabled the wireless on the laptop - and logging is much less, but I
still wonder why this logging continues.  What must I do to make it stop?

 

Here's the tail of that log:

writing poetry.  He replied that if there was no money in poetry, there was
certainly no poetry in money, and so it was all even."
