'dhcpd' to _only_ result in the listed action (with no further
evaluation of the file, and thus no further opportunities for
logging to be done), and the '!*' means that further evaluation
will happen if there _isn't_ such a match.


Ah, I see now.  I was just going from the example in syslog.conf, but 
this points me in the right direction.  Thanks!

syslogd program logging

[Steven Shockley]

My isc_dhcpd logs are kind of chatty, and I'd like to send them to their 
own log.  I tried appending the following to syslogd.conf:


!dhcpd
*.* /var/log/dhcpd

This works, but the dhcpd messages still appear in /var/log/daemon as well.

Is there a way to do this where syslogd will send logs from a specific 
program _only_ to the specified log file?  (Other than directly 
configuring a log file in isc_dhcpd.)


Thanks.
