Hi, the networking just drives me crazy and it seems that i am missing something. So here is my situation: i have a server with 2 public IPs (85.214.1.230 and 81.169.1.81) the dom0 is on: ip 81.169.1.81 netmask 255.255.255.255 gw 81.169.1.1 i would like to have a domU with ip 85.214.1.230. I tried everything routing, bridging.. nothing seems to work. my dom0 config; . (network-script

I am doing some testing of openwrt'd wireless access points, using madwifi-ng'd atheros radios. In the test configuration, I have three devices in a triangle, each has wds links to the other two devices. The ath0 interface is in ap mode, ath1 is a wds link to one device, and ath2 is a wds link to the other device. All three interfaces (and an ethernet interface) are in a bridge (br-lan)

My lenny guests don''t ping gateway. this is where I have found some probe HPCNL-SR-3:/etc/init.d# brctl showstp eth0 eth0  bridge id              8000.001b210d6131  designated root        8000.001b210d6131  root port                 0                    path cost                  0  max age                  20.00                 bridge max age            20.00  hello time               

Hi, I tried already a long time to enable network in my domU but I always fail with: # ifconfig eth0 192.168.0.1 up SIOCSIFADDR: No such device SIOCGIFFLAGS: No such device Do I need to load a kernel module? I use OpenSuse 10.2 with kernel 2.6.18.8-0.5-xen (for both domU and dom0). My config: kernel = "/boot/vmlinuz-xen" ramdisk = "/home/jens/initrd.gz" memory = 1024 name

dear all: I try to configure a bridge in my embedded linux. I had fininshed these operations below: 1) configure kernel, select the option "802.1d bridge" 2) compile bridge-utils 3) issue these commands: ifconfig eth0 0.0.0.0 ifconfig eth1 0.0.0.0 brctl addbr vb brctl addif vb eth0 brctl addif vb eth1 ifconfig vb 192.168.110.24 up

Hi, we're running the standard linux bridge setup (redundant bridge) for 5 years now. So first of all, thanks to everyone involved for implementing the bridging feature in Linux. Now I'm trying to bridge hosts connected to VLAN'ed Cisco switches using linux bridge. I'm testing the following setup (Kernel 2.6.19, bridge-utils 1.2 on both bridges)

It appears that interfaces participate in STP's forwarding delay even when STP is disabled for a given bridge. I can remedy by setting the FD to 0 for each new bridge, but I'm wondering if this is by design or oversight. [root@ ~]# brctl show bridge name bridge id STP enabled interfaces br0.690 8000.00065b8bce3e no eth1.690

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a machine running 2.6.18-rc3 with a bridge config that looks like this: cr1:~# brctl show bridge name bridge id STP enabled interfaces vlan100 36b0.0007e90f40c1 yes eth0.100 eth2.100 vlan101 5dc0.0007e90f40c1 yes

Hopefully I summed up the jist of the problem in the subject line. ;) I have a GFS cluster with ten Xen 3.0 dom0s sharing an iSCSI LUN. There are on average 8 domUs running on each Xen server. The dom0 on each server is hard-coded to 2 CPUs and 2GB of RAM with no ballooning, and has 2GB of partition-based swap. When creating a new domU on any of the Xen servers, just after the completion of

Hello, I've been trying to implement a bridge in place for a clustered firewall at one of our office locations. Currently we NAT two class C's internally. We decided, for performance reasons, that it would make sense to put our servers into an official DMZ. So we started this bridging project. Our goal is to have two redundant firewalls in place. There is no need for active/active.

hi everyone, so,first it seemed a trivial question to me, but since I could not find anybody being neither able to answer this question nor giving a short config example. after a few sleepless nights and exhausting all the reading and research. here I am sharing my problem with all of you, in the hope of some possible solution/sugestion. or is it that this is impossible?? below my

Raffaele If you don't want to see much arp traffic on eth1, assuming that you have a subnet 10.190.190.0/24, with 10.190.190.1 on eth1 and the rest of the hosts on eth0, you can use for example, the following filter ebtables -N f1 ebtables -P f1 DROP ebtables -t filter -A FORWARD -i eth0 -o eth1 -p ARP -j f1 ebtables -t filter -A f1 -p ARP --arp-ip-src 10.190.190.0/24 --arp-ip-dst

Hi all, Situation: We use smbtar for backups, incrementals done using -N <last date file>, and this has worked well with samba 2.2.x After upgrading to 3.0b3, using the -N (newer) option to smbtar causes a bad interaction with smbclient. Eg,: # smbtar -s PC -x Share -u User -p Pwd -d / -t - -N last-backup -v gives (if you print out the eval at the end of smbtar script): eval

Hi All, How do I find out about new new DHCP connections as they appear? I want to write a script that will do some stuff based on a new ip request from a machine on my lan. ie - new user connects to the lan, DHCP server on my Linux (debian) gateway gives them an IP, my script is run automatically to change the firewall rules and start recording their presents, or if it''s an unknown
