syslog differences depending on action

["Davis, Michael (Mike)" <davis.157%osu.edu@localhost>]

Say I have the following (consecutive) lines in /etc/syslog.conf:

*.err;kern.*;auth.notice;authpriv.none  @192.0.2.1 # not real address
*.err;kern.*;auth.notice;authpriv.none  user

(The whitespace is one or more tabs in production.)

When I'm logged on via SSH (for example) as "user," I see messages like...

May 20 11:08:47 mysys /netbsd: arp info overwritten for <IP-addr> by <MAC-addr>

...logged to my session.  This isn't showing up in the log file at 192.0.2.1, 
though.  Can anyone explain the difference in behavior, and how to get the same 
data logged to both destinations?  At the end of syslog.conf, I've got a 
"!ipmon" program specification (for ipfilter logging), and using "local0.*" as 
the selector, I have separate rules pointing to 'user' and 192.0.2.1, and both 
are working.

I'm running i386 NetBSD 6.1.2

Thanks,
Mike
