I have created a bridge with nmcli between eth0 and wlan0
I use this procedure

Hi all,
I need to add domain and search parameters to resolv.conf, however network manager overwrites.
Setting the PEERDNS=No in the interface file seems to have no effect on this behaviour.
Sadly I cannot just disable NM as these are not my hosts, I'm just attempting to install a platform... (3 Replies)
Once again, almost the same problem, not really solved. I need a hint for network configuration on bsd 10.1.
In the GUI for the network network manager I set two different DNS addresses. As well as the user@domain,com at hostname, broadcast is on 255.255.255.0
After restarting the machine trying... (0 Replies)
Dear Engineer,
Can anyone please inform me some application name like (CBQ) to control network bandwidth and please provide me the url to configure it.

Many papers, articles and posts about network bandwidth requirements refer to network traffic rules-of-thumb when estimating bandwidth requirements for a new network with an unknown load. I've seen a couple rules for video and VoIP.
I'd be thankful if someone could share any rules-of thumb they... (5 Replies)
We are using hp's network node manager and would like to monitor quite a few of our aix boxes. It appears that nnm does not have AIX mibs by default. Does anyone know where i can find mibs for aix to load into nnm? Thanks (0 Replies)
DUMMYNET(4) BSD Kernel Interfaces Manual DUMMYNET(4)NAME
dummynet -- traffic shaper, bandwidth manager and delay emulator
DESCRIPTION
The dummynet system facility permits the control of traffic going through the various network interfaces, by applying bandwidth and queue
size limitations, implementing different scheduling and queue management policies, and emulating delays and losses.
The user interface for dummynet is implemented by the ipfw(8) utility, so please refer to the ipfw(8) manpage for a complete description of
the dummynet capabilities and how to use it.
Kernel Options
The following options in the kernel configuration file are related to dummynet operation:
IPFIREWALL enable ipfirewall (required for dummynet)
IPFIREWALL_VERBOSE enable firewall output
IPFIREWALL_VERBOSE_LIMIT limit firewall output
DUMMYNET enable dummynet operation
HZ set the timer granularity
Generally, the following options are required:
options IPFIREWALL
options DUMMYNET
options HZ=1000 # strongly recommended
Additionally, one may want to increase the number of mbuf clusters (used to store network packets) according to the sum of the bandwidth-
delay products and queue sizes of all configured pipes.
SEE ALSO setsockopt(2), if_bridge(4), ip(4), ipfw(8), sysctl(8)HISTORY
The dummynet facility was initially implemented as a testing tool for TCP congestion control by Luigi Rizzo <luigi@iet.unipi.it>, as
described on ACM Computer Communication Review, Jan.97 issue. Later it has been modified to work at the IP and bridging levels, integrated
with the ipfw(4) packet filter, and extended to support multiple queueing and scheduling policies.
