similar to: How to block connections on spanned host ?

Hello. I would like to know if somebody did a wireles voip with Asterisk PBX. I think to deploy a wireless for about 500 potential customers, it's a 3 km radius maximum coverage with houses without phone lines, I work for public places telephony small enterprises ( a common bussines in Spain) so I can get good rates from 4 telcos and do LCR at my asterisk PBX. Is anybody did this before

I am trying to get the equivalent of promisc mode to pass all received traffic to a kvm guest that is running snort. So I have a cisco switch with span port plugged into eh2 on my kvm host which is centos. I want the kvm host to forward all promisc traffic from the span port to the guest running snort of tcpdump. What would be the best way to do this?

hello ... how can I identify huge downloads on link to automticly move them to low priority queue ? somethink like combination rate and duration of session Thanks

Hi, my name is Calin and I''m new to linux, but I guess its the right place to ask this: what do I set on a linux RH9 box with 2.4.24 kernel to route a 10 machine private network (192.168.x.x) by 3 limited bandwidth, public IPs (193.231.x.x). The network uses a switch, the linux box has 1 ethernet card, the link is available trough a wireles ethernet bridge from my ISP. I begun to read

From: Andy Lutomirski <luto at amacapital.net> Once virtio starts using the DMA API, we won't be able to safely DMA from the stack. virtio-net does a couple of config DMA requests from small stack buffers -- switch to using dynamically-allocated memory. This should have no effect on any performance-critical code paths. Cc: netdev at vger.kernel.org Cc: "Michael S. Tsirkin"

In current Crossbow''s implementation, vlan tag seems to be unconditionally retained for promisc mode listener even when MAC_OPEN_FLAGS_TAG_DISABLE is not specified. I saw comments in mac_rx_deliver() saying that this is deliberately designed like this. I''m wondering why we design it like this (choose not to respect MAC_OPEN_FLAGS_TAG_DISABLE flag for promisc mode listener)? Or

We have DELL R910 with H800 adapter in it. several MD1220 connect to H800. Since MD1220 have 24 hard disks in it. When I configured RAID10, there is a choice call 'single spanned virtual disk" (22 disks). Can anyone tell me how "single spanned virtual disk" work? Any document relate to it? Thanks.

When sending control commands, virtio net sets up several buffers for DMA. The buffers are all part of the net device which means it's actually allocated by kvmalloc so it's in theory (on extreme memory pressure) possible to get a vmalloc'ed buffer which on some platforms means we can't DMA there. Fix up by moving the DMA buffers into a separate structure. Reported-by: Mikulas

Hello, I have been using the bridging facilities provided by Linux (vanilla 2.6.7 SMP with UML skas host patch applied) to bridge a regular physical ethernet network (on interface eth0) with a virtual network (on interface tap0, cf uml_switch, http://user-mode-linux.sourceforge.net/networking.html). A couple of virtual machines (run using user-mode linux, a tool that enables you to run linux

To give fast web browsing on my network, I prioritise http traffic by marking it all into a high priority band (''30''). This generally works quite well, as unidentified traffic such as p2p falls by default into a lower priority band (''40''). However, I would like to de-prioritise anyone doing large downloads over http, which currently get high priority. Is there

Hi, I am a beginner of bridge. I have a problem of using Fedora Core 2 to make a simple bridge. Here is my setup: The bridge computer is installed with Fedore Core 2 (with the SE Linux patch). As I know that kernel 2.6.5 is already support bridging by default, so I didn't recompile the kernel. Then I installed bridge-utils-0.9.6-1.i386. And no additional configuration is made. After

Hi, I am using linux kernle-2.6.15, iptables-1.4 and bridge-utils-1.4. Everything intslled without any issue and i am able to enable the bridge and traffic is also flowing without any issue. But i did not see any traffic on the iptables forward chain due to which i am not able to control the traffic. Do i requie enable anything more to make the traffic pass through iptables forward chain.
