Logging date of DHCP transactions ?

[James Jalbert]

I use the following script to create a csv file, then I import it into my database I have setup. I am using Ubuntu for dhcp, but I assume it should be the same for all flavors


tail -n 2000 /var/log/dhcp.log | awk '/DHCPACK on/ {print $1" "$2" "$3","$8","$10}' > /home/netop/IPLog.csv

According to the man page, dhcpd(8),

http://www.freebsd.org/cgi/man.cgi?query=dhcpd&apropos=0&sektion=0&man 
path=FreeBSD+9.2-RELEASE+and+Ports&arch=default&format=html


"...Normally, dhcpd will log all output using the syslog(3) function
with the log facility set to LOG_DAEMON.
..."


You can direct that output to a specific file by adding something
like:

 daemon.info               /var/log/daemon

to your /etc/syslog.conf file, and then touching /var/log/daemon to
assure the file exists.  You may also want to add that log to the
/etc/newsyslog.conf file so it gets rotated.



Hope this helps.
