This is useful in setting up networks for a hosted virtual machine (VM). &lfs84_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &bridge-md5sum; Download size: &bridge-size; Estimated disk space required: &bridge-buildsize; Estimated build time: &bridge-time; bridge-utils Dependencies Optional (to run tests) User Notes: Enable the following options in the kernel configuration and recompile the kernel if necessary: [*] Networking support ---> [CONFIG_NET] Networking options ---> <*/M> 802.1d Ethernet Bridging [CONFIG_BRIDGE] Bridge Utilities Install bridge-utils by running the following commands: autoconf && ./configure --prefix=/usr && make Testing the results requires running the six shell scripts in the tools/ directory. Two of the tests require two ethernet ports. Some tests will not preserve the current network configuration. See tests/README for details. Now, as the root user: make install To automate bridge creation and configuration, install the /lib/services/etc/bridge service script included in the package. bridge-utils make install-service-bridge The bridge script depends on the commands /sbin/ifup and /sbin/ifdown and the service script ipv4-static from the LFS bootscripts dated January 27, 2012 or later. The following configuration file will create a bridge device at boot time and attach the eth0 device to it. If more than one device is desired, use a space separated list of INTERFACE_COMPONENTS. This configuration is useful when planning to run a virtual machine such as kvm/qemu. Other SERVICE combinations are possible, for example, SERVICES="bridge dhcp". In that case, the address parameters are not needed, but do not interfere if present. The bridge service may also be used alone, but will require additional subsequent configuration. Do not run a parallel configuration for a device in the INTERFACE_COMPONENTS list. For instance, in the example below, do not configure /etc/sysconfig/ifconfig.eth0 to run at boot time. The command ifdown br0 followed by command ifup eth0 will work, but don't try to have both up at the same time. cat > /etc/sysconfig/ifconfig.br0 << "EOF" ONBOOT=yes IFACE=br0 VIRTINT=yes SERVICE="bridge ipv4-static" # Space separated IP=192.168.1.32 GATEWAY=192.168.1.1 PREFIX=24 BROADCAST=192.168.1.255 CHECK_LINK=no # Don't check before bridge is created STP=no # Spanning tree protocol, default no INTERFACE_COMPONENTS="eth0" # Add to IFACE, space separated devices IP_FORWARD=true EOF All addresses should be changed to meet your circumstance.
