Okay thanks!
But I'm wondering... All these HOWTOs I see are based on a router like
setup, ie sharing on internet link with several boxes and shape this.
But wat I'm looking for is shaping per box, for example:
One box has 100 virtual HTTP domains on it, and per domain we limit now
with MOD_BANDWIDTH the max bandwidth they can use: I understand that
this is the best way to do, since the virtual domains; so mainly when
you want to do bandwidth limiting on virtual stuff, you have to look for
a daemon (or module) that support this internaly.
But on the same box each customer can upload/download their website via
PROFTPD (MySQL Auth). How should I limit the (overal) FTP port
bandwidth?
And even more specific, we have some services running on, lets say, port
60000 and want to limit only this port on the box.
What I like to achieve is that we can shape every port of the several
boxes separate, but am wondering the overhead per box, disadvantages
etc. I understand that dummynet is the way to do this... Or not? And
if... How ... ;-)
Heck, I feel like a complete newbie right now on this specific base ....
Thanks again!
- Casper

Hi.
Yeah, there is one dummynet howto on bsdpro.com that makes things pretty
clear.
An example of my dummynet rules:
### Dummynet bandwith limiting :) #####
#All machines share evenly a single link - 1000Kbit/s
$fwcmd $flags add pipe 1 ip from any to 192.168.64.0/24
$fwcmd $flags add queue 1 ip from any to 192.168.64.0/24
$fwcmd $flags queue 1 config weight 5 pipe 1 mask dst-ip
0x000000ff
$fwcmd $flags pipe 1 config bw 1000Kbit/s
#Except for some boxes .... :)
#Servers:
$fwcmd $flags add 6 skipto 2001 ip from any to 192.168.64.4/32
$fwcmd $flags add 6 skipto 2001 ip from 192.168.64.4/32 to any
$fwcmd $flags add 6 skipto 2001 ip from any to 192.168.64.5/32
$fwcmd $flags add 6 skipto 2001 ip from 192.168.64.5/32 to any
I have an entry in /etc/sysctl.conf as well:
#walk through several pipes but not just one:
net.inet.ip.fw.one_pass=3D0
Good luck.
