search for: bridge0

I am experimenting with a kvm virtual machine. At the moment I trying to configure iptables for the the host instance. In Xen terms I would call this Dom0 but I do not know the appropriate KVM term, if any. The setup I have is a single NIC (eth0) host bridged (bridge0). I want iptables to allow all host generated traffic (! bridge0 I think) and to check all other traffic for brute force attempts coming in over the LAN. I have the following rules in /etc/sysconfig/iptables: . . . -A GENERAL -m comment ! -i bridge0 -j ACCEPT . . . -A GENERAL -m comment -m st...

...all works perfectly, but as soon as I do this on another machine on a public IP, I'm not getting any routing, I can't even ping it from the same machine ... My first thought was that there was an issue with IP aliases already on the bge device, but tried doing the following: ifconfig bridge0 destroy ifconfig tap0 destroy ifconfig fxp0 -alias 192.168.1.101 ifconfig fxp0 alias 192.168.1.101 netmask 255.255.255.255 ifconfig bridge0 create ifconfig tap0 create ifconfig bridge0 addm fxp0 addm tap0 up on my desktop here and then starting up the qemu image, and all worked as expected, so ha...

Hello. I desire to get bridge network working using virt-manager. Centos 7 and centos 7 guest. >From researching I think I need to have a ifcfg-br0 file like this ? cat ifcfg-br0 DEVICE=nm-bridge0 STP=no TYPE=Bridge BOOTPROTO=none IPADDR=192.168.1.8 PREFIX=32 GATEWAY=192.168.1.1 IPV6INIT=no NAME=br0 ONBOOT=yes DELAY=0 Is that for sure needed ? The use that nm-bridge0 as the network name? I dont want to mess up my current setup. Thanks, Jerry

Hi, I'm using system-config-firewall (C6 x86_64, fully up to date) to configure a gateway/firewall box. 2 nics, eth0 (configured as bridge0, mtu 7200) connected to the lan, eth1 being connected directly to the internet (public ip, mtu 1500). ssh port is open and accessible. nat is working fine. I've put bridge0 as a trusted interface, eth1 is masqueraded. I've put ports 20,21,80 as forwarded ports on eth1 to lan machines. Thing...

Hi all, Is it mandatory to add device mem to jails to enable network via the gateway? Left ezjail with FreeBSD-6.3 (and a hardware replacement of my server) and am now starting again with FreeBSD-7.1. Early this week, I upgraded from 7.0 to 7.1 (not having 'used' jails on 7.0). After creating the jail with `ezjail-admin update -i` I created a 'ports build' jail `ezjail-admin

Hello, with CentOS 6, my new server created an UUID entry in ifcfg-eth0 - additional to HWADDR entry. Up to CentOS 5 the connection to the netwark card was defind only by HWADDR. Now I have a new network card. How can I get the correct UUID? The server connects correct the network with the updated HWADDR without any UUID. Why do I need an UUID? Thank you for help in advance. Best Regards

Hi, I have a Windows 7 SP1 Pro 64-bit VM which works fine on libvirt 2.3.0 and Qemu 2.7.0. If I enable HyperV features (https://libvirt.org/formatdomain.html#elementsFeatures) like "relaxed", "spinlocks" etc - VM doesn't boot. "Starting Windows" text appears for ~2 seconds (no flying dots, no logo) and then it just goes to black screen. If I switch HyperV
