Hello
I need to limit the bandwidth from a list of ip addresses. I was planning to use the dummynet with lookup tables, so i took the example given in the manual pages:
I modified the network addresses as needed but there seems to be a problem with the last line:
I tried to do it another way, but it didn't work too:
I'm using FreeBSD 6.1
Could someone tell me what i'm doing wrong or where to find some info
i have two questions actually...
i need to block certain ports with openbsd and PF in a large lan, the firewall is supposed to be a router between the internet and the first lan switch.
first of all, would this work at all in theory?
second, i tried doing this a few days ago at a huge lan but i... (2 Replies)
Hello,
I was wondering how one would go about regulating bandwidth of a server running RH Linux 8.0 and Apache. I am running a webserver, and want only one person to be able to download one file at a time. So, they can't click about 10 files and soak up lots of bandwidth. Plus, I would like to cap... (2 Replies)
Hi,
I'm looking for some way to bring up in a shell window a realtime (or something that updates at 10 second intervals or whatever) bandwidth monitor.
I just want something that shows me how much kbps is going in and how much is going out of each interface. Is there something that might... (2 Replies)

Hi!
I've already posted this on the freebsd-questions mailing list, but I thought I could try it here too.
I'm using FreeBSD 7.0 with IPFW DUMMYNET enabled.

IPFW(4) BSD Kernel Interfaces Manual IPFW(4)NAME
ipfw -- IP packet filter and traffic accounting
SYNOPSIS
To compile ipfw into the kernel, place the following option in the kernel configuration file:
options IPFIREWALL
Other kernel options related to ipfw which may also be useful are:
options IPFIREWALL_DEFAULT_TO_ACCEPT
options IPFIREWALL_FORWARD
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=100
To load ipfw as a module at boot time, add the following line into the loader.conf(5) file:
ipfw_load="YES"
DESCRIPTION
The ipfw system facility allows filtering, redirecting, and other operations on IP packets travelling through network interfaces.
The default behavior of ipfw is to block all incoming and outgoing traffic. This behavior can be modified, to allow all traffic through the
ipfw firewall by default, by enabling the IPFIREWALL_DEFAULT_TO_ACCEPT kernel option. This option may be useful when configuring ipfw for
the first time. If the default ipfw behavior is to allow everything, it is easier to cope with firewall-tuning mistakes which may acciden-
tally block all traffic.
To enable logging of packets passing through ipfw, enable the IPFIREWALL_VERBOSE kernel option. The IPFIREWALL_VERBOSE_LIMIT option will
prevent syslogd(8) from flooding system logs or causing local Denial of Service. This option may be set to the number of packets which will
be logged on a per-entry basis before the entry is rate-limited.
Policy routing and transparent forwarding features of ipfw can be enabled by IPFIREWALL_FORWARD kernel option.
The user interface for ipfw is implemented by the ipfw(8) utility, so please refer to the ipfw(8) manpage for a complete description of the
ipfw capabilities and how to use it.
