Thanks, it's the default drop.  Which makes me wonder... how the heck do I
let these in w/out a port number???

Nothing special, just a couple of boxes directly connected to the switch side
of a lynksys ADSL router.

This whole thing turned up another damm problem though... ipmon on the sparc64
isn't working.

The man page says to use facility local0, so I put this in /etc/syslog.conf:

local0.*	/var/log/ipfilter_log

Nothing.  I even tried catching it with *.*

I also tried it from the command line, no errors or anything, but no output
there either.

to be sure...

adam@ultra% ls -l /var/log/ipfilter_log
-rw-------  1 root  wheel  0 Jul 31 10:51 /var/log/ipfilter_log

I'm using the GENERIC kernel and I see that IPFILTER_LOG is turned on.

maybe somebody can tell me where I'm going wrong here?

I can give you the whole body of the packets if you want.

Or maybe somebody knows how to convert those 'foo.giv,v' files that are
avaliable via ftp into files I can use (I'm stuck on 'sitedrivenby.gif' on my
apache install) (from the 'htdocs' dir)

Sorry to lay a bunch of stuff on you all, just wherever I try to work-around,
I run into another dead-end.

Thanks
