Bridge
From Linuxintro
You will need a (software) network bridge on your computer if you
- Set up a wireless accesspoint
- use kvm virtualization
Setup
To set up a bridge you need to find out your distribution and proceed accordingly:
SUSE
- open a console and enter
yast2 lan
- then choose Add -> Bridge -> Next -> Bridged Devices -> ethx.
Ubuntu
- install brctl:
sudo apt-get install bridge-utils
- verify your bridge br0 has been set up:
tstaerk@dell-desktop:~$ brctl addbr br0 add bridge failed: Operation not permitted tstaerk@dell-desktop:~$ sudo brctl addbr br0 tstaerk@dell-desktop:~$ ip a s 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000 link/ether 00:22:19:f7:3c:bb brd ff:ff:ff:ff:ff:ff 3: wmaster0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 link/ieee802.11 00:22:fb:89:57:06 brd ff:ff:ff:ff:ff:ff 4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000 link/ether 00:22:fb:89:57:06 brd ff:ff:ff:ff:ff:ff 5: pan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether d6:2a:40:12:ff:bc brd ff:ff:ff:ff:ff:ff 6: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 3 link/ppp inet 10.57.81.93 peer 10.64.64.64/32 scope global ppp0 7: br0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether 06:ed:32:47:91:a2 brd ff:ff:ff:ff:ff:ff
