Stephen Hemminger, Yes,I use V2.4.17. Which patch can I use?

Hello, I have the need to connect 2 remote site with vpn, the windows pc of the 2 site it can share the HD and printer. This is my configuration : LOCAL NETWORK A : ip from 192.168.10.2 to 192.168.10.99 | | | | eth0: 192.168.10.1 FIREWALL A : ( with debian ; openvpn ver. 2.0.beta15 ; shorewall ver 2.0.11 ) eth1 : xxx.xxx.xxx.xxx ( pubblic ip address ) | | | | INTERNET | | | eth1 :

Here is the proposed revision to the bridge utilities interface to the kernel. The driving force is that the existing interface can't easily be converted to 32/64 bit compat. Right now, the bridge-utils (brctl) tries to handle 32bit command on 64 bit kernel, but the code is limited to sparc and wrong. Here is what I am thinking. get version - not needed? get bridges -

When i want to delete my test bridge, using: ifconfig eth0 down ifconfig eth1 down ifconfig br0 down brctl delif br0 eth0 brctl delif br0 eth1 brctl delbr br0 i get this error message from the kernel on the console: unregister_netdevice: waiting for br0 to become free. Usage count =3D 2 The brctl user-level command is blocked. Could you explain me what could likely be the cause of this error?

Hi there, I'm currently experiencing a minor problem using the bridge module under kernel 2.4.27 part of the Devil Linux distribution (http://www.devil-linux.org). The problem I am having is that when the bridge is unloaded during a reboot I receive the following errors in /var/log/messages: Nov 14 13:22:13 src@Devil kernel: unregister_netdevice: waiting for br0 to become free. Usage count =

Hi guys I am trying to keep a linux bridge up even when there is no interface connected to it.

Hello Greg: One older server is an NT DC, and the two others (including the WINS server with Active Directory,

I have a new Polycom Spectralink 8002 and am having trouble with the configuration or the unit but I can't see what's wrong. The unit does not seem to even attempt to register with the Asterisk proxy but I can make calls to it. I have viewed the syslog from the device which it will actually write to the asterisk server so I know it can be reached. I have also run a sip debug and

When I start xen dom0 I get that same dhcp address for eth0 and for xen-br0, dom0 can talk to the world. If I start each of my 3 domU''s mannually, each guest gets a xen-br0 vif with a dhcp address and all 3 can talk to the outside world and each other (my "flat network"). What I want is a tiered network with the first domU acting as a firewall with 3 nics vif = [

I can’t seem to find info about layer 2 tinc tap interface bridge with local physical nic. I have successfully created two nodes configuration with tinc acting as switch. My problem is ethernet packets only flow between two nodes and not to hosts on bridged nic. Example: Server 1 - eth0 bridged with tinc tap device, then bridge gets IP via dhcp server on physical nic subnet. Server 2 - local

Hi, I've been encountering some problems with bridging under linux 2.6.12-9 (ubuntu Breezy Badger). Apologies for the newbie-ish email: problem is likely a config issues, but docs appear to be sparse and I can't find much reference to the problem/solution on the 'net; trial and error really isn't working... Am attempting to bridge an offsite network to the central

With recent 2.6 kernels, the command brctl delbr br0 hangs during shutdown, and the kernel prints this message again and again: unregister_netdevice: waiting for br0 to become free. Usage count = 1 I was able to reproduce this problem with several kernels between (and including) 2.6.9-rc1 and 2.6.11-rc2-bk9. I haven't tried later versions than 2.6.11-rc2-bk9 yet. 2.6.8.1-bk2 still works

Hi, Guus Thanks a lot for your suggestion, actually I did something else as below. But one question here is if I don’t add "/sbin/ifconfig myvpn 10.0.0.1 netmask 255.255.255.0”, it seems the crontab wouldn’t trigger tinc-up, and then the ip addr of myvpn wouldn’t be configured, then it will prompt the error of "Can't write to Linux tun/tap device (tun mode) /dev/net/tun:

I'm scratching my head here a little. And my post to the openvpn mailing list is not getting any attention. I have an openvpn server working with Windows clients and I thought I'd try to get a client config on a CentOS box running. The client is a minimal install of CentOS and I like to use shorewall (3.2.x). I've tried to run the vpn client with the fw off and on with no change.

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup:
