I know how that is, I've missed stuff in the manpages too.

Not dumb.  You had a question and you asked it on freebsd-questions
looking for an answer.  That's smart in my book.  That's what the 
list is for.

Would this work for you?  From the manpage:

 For those who wish to be sure that specific ports are always compiled
 instead of being installed from packages the PT_NO_INSTALL_PACKAGE vari-
 able can be defined in the make(1) environment, perhaps in
 /usr/local/etc/ports.conf if using /usr/ports/ports-mgmt/portconf, or in
 /etc/make.conf.  This setting is not compatible with the
 -PP/--packages-only option.

Is this what you want?

sed -n 's/^\([0-9]\{1,\}[gm]\)$/\1/p'

Prints output only if the input begins with digits and ends with g or m.

Or this?

sed -n 's/^\([0-9]\{1,\}\)[gm]$/\1/p'

Prints numeric output only if the input begins with digits and ends with g 
or m.

"NTP was not designed to run inside of a virtual machine. It requires a high 
resolution system clock, with response times to clock interrupts that are 
serviced with a high level of accuracy. No known virtual machine is capable of 
meeting these
requirements.

Run NTP on the base OS of the machine, and then have your various guest OSes 
take advantage of the good clock that is created on the system. Even that may 
not be enough, as there may be additional tools or kernel options that you need 
to enable so that
virtual machine clients can adequately synchronize their virtual clocks to the 
physical system clock. "

/etc/namedb is a link to another directory, don't use the trailing

Shouldn't this be:

Where aaa.bbb.ccc.ddd is not the other gateway (aaa.bbb.ccc.196)
I.e, aaa.bbb.ccc.ddd should be an address on the switch aaa.bbb.ccc.209

Maybe even adding ' -interface ' at the end of the command.
