66.92.43.99: Another method (file name should be known in advance).

ok, so how do you start and stop the firewall? In linux it's a simple "iptables stop" (or start) -- or the redhat dumbed down version is "service iptables stop"....curious how it's done in FreeBSD (haven't had a need to put a FW on one yet...)

== also, typo? ==

# let everything on your internal network talk to the firewall
$cmd 01101 allow all from any to any via $iif keep-state

shouldn't this be
# let everything on your internal network talk to the firewall
$cmd 01101 allow all from $inside to any via $iif keep-state

== $inside to any via $iif ==

If you're concerned with preventing address spoofing FROM your internal network going OUT to the real world, yes.

I tend to prefer my firewalls to let me-the-user do pretty much anything I want to, as a general rule. It shouldn't really make a whole lot of difference, in practice. --[[User:Jimbo|Jimbo]] 00:13, 7 Sep 2005 (EDT)

== starting and stopping the firewall ==

There isn't any real "omg this stops and starts it" sort of command - you just issue the rule commands you want, either directly from the command line or from a script.

For instance that ruleset in the article? Notice that the first line is #!/bin/sh - you guessed it, it's a Bourne shell script, so to start a firewall with that ruleset you would just run that script. You have to define what a "stopped" condition is before I can tell you how to "stop" the firewall. By "stop the firewall" do you mean "drop all traffic" or "pass all traffic"? --[[User:Jimbo|Jimbo]] 00:17, 7 Sep 2005 (EDT)

== Start/stop ==

In this article, the IPFW is loaded via the kernel, if the firewall was loaded via kernel module, you could issue a "kldunload ipfw.ko".

== dunno about running it as a module ==

Never tried. Everything I read said that you *needed* to build an ipfw kernel, that many things just didn't work properly when you tried to kldload it as a module. I'm not saying I know for a fact that it won't work, just that that's what I've read, and that I haven't tried anything otherwise.

Also, with that said - if you DID build it into the kernel, there IS no such thing as "stopping the firewall" in the manner of kldunloading a module. If it's built into the kernel, the firewall is ALWAYS running - "up" or "down" is a matter of what the ruleset is, not of actually "stopping" a service or daemon. --[[User:Jimbo|Jimbo]] 21:09, 7 Sep 2005 (EDT)

One uncommon way to configure the firewall is find configuration
files on the web and test a heavily commented one *carefully*, then
if it works one essentially does not need to learn the syntax.
Might save a little time...

66.92.43.99:

A certain media (mp3, ogg, .txt, jpeg ) flash memory device I recently
mounted thusly:

1... computer on
b... connect flash device to usb cable
c... turn on flash device ("power and data" on its menu, vs the other modes)
d... camcontrol rescan all
e... mount -t msdosfs /dev/da0 /mnt

It has two modes to transfer files. One method will reformat and
lose the data on your flash media device... so use MSC not MTP
( although the latter has /ports/ enabling it (mtpfs; libmtp) ).

66.92.43.99: A Safer Rm

if you alias rm to "echo something" you can
mandate the full path "/bin/rm " which
allows a few seconds of "should I do this"
as you type. Been doing that for years with
good results
